2. Description of the Related Art FIG. 19 (a) shows a configuration example of a conventional operation test device for an auxiliary storage device. In FIG. 19 (a), the information processing device 410 has two channel control units 421a and 421a.
21b is connected to the auxiliary storage device 430,
An access process to the hard disk drive 432 is performed via the two disk control units 431a and 431b provided in the auxiliary storage device 430.

In this information processing apparatus 410, the two test program processing sections 411 have channel control sections 421 corresponding to paths for which input / output request instructions are sequentially designated according to two different test programs a and b.
The data is transmitted and received via the auxiliary storage device 430. At this time, the two test program processing units 4 corresponding to the test programs a and b
11a and 411b are the hard disk drives 43 of the auxiliary storage device 430 with the respective conditions set.
It is only necessary to send an input / output request command instructing writing / reading for 2 and receive the response and access result of the auxiliary storage device 430 to this.

Further, in FIG. 19 (a), the input / output monitoring unit 412 includes a test program processing unit 411a,
The I / O request command and the interrupt notification indicating the end of the I / O operation from each of the 411b are monitored, and the above-mentioned is performed within the monitoring time set in the timer 413 after the I / O request command is issued. The configuration is such that the success or failure of the input / output operation is determined based on whether or not there is an interrupt notification.

In this operation test device, the above-mentioned 2
The input / output request commands issued by the two test program processing units 411a and 411b are processed as independent commands, and when the timings of access operations by these commands conflict, the execution order is arbitrated. Stayed

[0007]

The input / output request commands issued by the respective test program processing units 411a and 411b are as follows.
Basically, they can be handled as independent input / output instructions, but when accessing the same device (for example, hard disk drive 432) through different paths, the access operation order is simply arbitrated. Sometimes just doing is not enough.

For example, the test program processing unit 411
Both a and 411b are hard disk drives 432.
In the case of simultaneously performing the writing / reading test to / from the storage medium via the disk, the test program processing unit 411a uses the channel control unit 421a and the disk control unit 431a to pass the path A through the i-th track of the storage medium. Immediately after writing the specific data in the j-th record of, the test program processing unit 411b overwrites another data on the same record via the path B via the channel control unit 421b and the disk control unit 431b. There is a possibility that it will end up. In this case, the test program processing unit 41
Regardless of the actual success or failure of the processing result of the I / O request command issued by 1a, a read error will occur in the subsequent read processing due to the occurrence of the above-described overwrite processing, and the performance of the auxiliary storage device 430 will be validated. Can not be evaluated.

On the other hand, for example, as shown in FIG. 19B, the hard disk drive 43 is stored in the auxiliary storage device 430.
3 is added and two hard disk drives 432, 4
If the disk control units 431a and 431b independently control 33, the disk control unit 431
Since the load on a and 431b increases, the time required to complete the input / output processing may increase.

In this case, if the input / output processing completion time set in the information processing system shown in FIG. 19 (a) is applied, the monitoring of the input / output processing completion time is performed regardless of the actual success or failure of the input / output processing. The input / output monitoring unit 412 may determine that the input / output processing has failed in response to the notification from the timer 413 for this reason, and thus the performance of the auxiliary storage device 430 cannot be properly evaluated. .

As a method of avoiding such a phenomenon in the conventional operation test device for the auxiliary storage device, the program developer recognizes the configuration of the information processing system as shown in FIG. A method is conceivable in which the test programs a and b suitable for the system configuration are respectively created by designating the tracks to be subjected to the write / read test and setting the input / output processing completion time. However, in this case, it is necessary to create each test program according to the configuration of various information processing systems, which increases the burden on the program developer.

An object of the present invention is to provide an operation test device for an auxiliary storage device capable of automatically adjusting the operation of a test program according to the system configuration.

Accordingly, when the plurality of test program processing units 411 independently perform the operation test of one device, it is possible to prevent the occurrence of a read error due to the interference of other test programs, and thus it is possible to flexibly adapt to various system configurations. Correspondingly, the performance of the auxiliary storage device 430 can be properly evaluated.

Moreover, as described above, the test target track is assigned automatically by the test control processing section 210. Therefore, in this case, the program developer selects each test program processing section 411 as a test target. It is not necessary to be aware of the track, and the work load on the program developer can be greatly reduced. The series of channel command words rewritten in step 303 described above are sequentially input to the monitoring time calculating unit 217, and the monitoring time calculating unit 217 determines the time required for the input / output processing instructed by these channel command words. The monitoring time is calculated based on the setting, and is set in the timer 413, so that the input / output monitoring unit 412 provides the monitoring process.

FIG. 13 shows the detailed structure of the monitoring time calculating section. The cache determination processing unit 231 shown in FIG. 13 uses the determination means 13 described in claim 5 in step 304.
1 and operates as described above, and the system configuration table 214 described above.
Also, based on the device information table 215, it is determined whether or not actual access to the hard disk drive 432 is necessary for each channel command word included in the command sequence.

FIG. 14 is a flow chart showing the processing for determining the necessity of actual access. At this time, the cache determination processing unit 231 first refers to the system configuration table 214 and the device information table 215 to determine whether the disk control unit 431 forming the path designated by each channel command word has a disk cache. Is determined (step 311).

In the case of negative determination at step 311,
The hit / miss table 232 stores the judgment result indicating that there is a miss corresponding to all the channel command words, and also sends these channel command words to the command analysis section 233 (step 312), thus ending the judgment processing. Good. On the other hand, in the case of a positive determination in step 311, the cache determination processing unit 231 determines whether or not the disk cache is softly separated based on the corresponding device information in the device information table 215 (step 313). If the determination is affirmative, the above-described step 312 may be executed to end the determination processing.

Further, in the case of a negative judgment in step 313, the cache judgment processing unit 231 judges whether or not the target data exists in the disk cache for each channel command word, and hits this hit judgment result. / Store each in the miss table 232 (step 3
14) Then, the channel command word for which the determination result indicating the error is obtained is sent to the command analysis unit 233 because it is necessary to actually access the channel command word (step 315), and the determination process may be ended.

In this way, the cache determination processing unit 231
Performs the processing of step 311 and step 313, so that the first usage determining unit 134 described in claim 6 is executed.
The above function can be realized, and the presence / absence of a hard disk cache and the presence / absence of a soft disconnection of the disk cache can be reflected as a test condition in the monitoring time calculation process described later. In addition, the functions of the hit determination means 135 and the determination result output means 136 are realized by performing the processing of step 312 or steps 314 and 315 according to the determination results of step 311 and step 313, and for each channel command word The hit determination result can be reflected in the monitoring time calculation process described later.

As a result, the monitoring time can be accurately calculated according to the detailed test conditions regarding the cache memory assumed by the test program. The determination result for each channel command word thus obtained is provided to the processing of the command analysis unit 233 and the transfer byte calculation unit 234 as shown in FIG.

In FIG. 13, the command analysis unit 233
Is configured to perform an analysis process, which will be described later, on the channel command word for which the actual access process is required by the cache determination processing unit 231 described above. In addition, the transfer byte calculation unit 234, based on the hit / miss table 232 described above, the channel control unit 42.
1 and the transfer byte Bc between the disk controller 431 and the hard disk drive 432 and the disk controller 431 are calculated for each channel command word, and a transfer byte table 235 is created. Has become.

For example, as shown in FIG. 12, step 3
In response to the affirmative determination 04, the command analysis unit 233
The command analysis process is performed in step 305, while the transfer byte calculation unit 234 may perform the transfer byte calculation process in step 306 regardless of the determination result of step 304. After that, step 307
In step 3, it is determined whether or not the processing has been completed for all the channel command words, and in accordance with the negative determination in step 307, the process can return to step 304.

Here, for the channel command word which is determined to hit the disk cache, the transfer byte calculation unit 234 sets the transfer byte designated by the command as the transfer byte Bc corresponding to the corresponding channel command word, and the transfer byte table. On the other hand, regarding the channel command word which is held in 235, the transfer byte corresponding to the corresponding channel command word is stored in the transfer byte table 235 as the transfer byte Bc and the transfer byte Bd. Good.

As described above, the transfer byte calculating unit 234 performs the above-mentioned processing based on the hit / miss table 232, thereby realizing the function of the transmission analyzing unit 133 and providing the calculation processing of the basic time described later. Has become.
Next, the analysis processing by the command analysis unit 233 will be described in detail with reference to the flowchart showing the command analysis processing shown in FIG.

In response to the input of the channel command word,
The command analysis unit 233 first determines whether or not the channel command word is a seek command for moving the head of the hard disk drive 432 in the radial direction (step 321). In the case of a negative determination in step 321, the command analysis unit 233 determines whether or not the channel command word is a search command for detecting a target record in the track of the recording medium (step 322). In the case of a positive determination in this step 322, 1
The number of search operations nsc indicating the number of search operations included in the channel command word string transmitted each time is incremented by 1 (step 323). On the other hand, in the case of a negative determination in step 322, the command analysis process may be terminated. .

In this way, the command analysis unit 233 realizes the function of the operation determination means 141 described in claim 8 by performing the processing of steps 321, 322, and is instructed by each of the input / output request commands. Each mechanical operation can be discriminated and used for the monitoring time calculation process.
Further, in the case of the affirmative determination in step 321 described above, the command analysis unit 233 refers to the device information table 215 and determines whether or not a replacement track is assigned to the target track (step 324).

In response to the affirmative judgment at step 324,
The command analysis unit 233 adds 2 to the seek number nsk indicating the number of seek operations included in the channel command word string transmitted at one time (step 325). On the other hand, in the case of a negative determination, the seek number nsk is set. One is added (step 326), and the process may proceed to step 327. In this step 327, the command analysis unit 233
It suffices to determine whether or not the seek command input as the new channel command word and the seek command immediately before the seek command match the target track numbers.

In response to the negative determination in step 327,
In step 328, the command analysis unit 233 stores the information indicating the target track of the new seek command in the track information holding unit 236, and then ends the command analysis process. The command analysis unit 233
The information regarding the target track designated by the immediately preceding seek command may be obtained from the track information holding unit 236, and the determination processing in step 327 described above may be performed.

On the other hand, in the case of affirmative determination in step 327, since the head has already moved to the target track by the immediately preceding seek operation, it is not necessary to perform another seek operation in response to a new seek command. The seek count nsk may be adjusted by subtracting 1 from the seek count nsk (step 329), and then the process may proceed to step 328.

In this way, the required mechanical operation is analyzed for at least one channel command word sent at one time, and the seek number nsk and the search number nsc indicating the number of times the seek operation and the search operation are executed, respectively. And step 3 as the command analysis result.
It is possible to provide the basic operation time calculation processing of 08. In particular, the command analysis unit 233 performs the process of step 324 described above, thereby realizing the function of the first instruction determination unit 142 described in claim 9, and according to the determination result,
By performing the processing of step 325 and reflecting the occurrence of the extra seek time due to the designation of the defective track in the seek number ns, the function of the first operation time adjusting means 143 is realized, and the basic time calculating unit 237. The resulting basic time can be adjusted.

Further, the command analysis section 233 realizes the function of the second instruction determining means 145 described in claim 10 by performing the processing of step 327 described above, and in accordance with the determination result, the operation of step 329 is executed. By performing the processing and reflecting the decrease in seek time when the same track is designated in the seek count ns, the function of the second operation time adjusting means 146 is realized, and similarly, the basic time calculating unit 2
The basic time obtained at 37 can be adjusted.

In FIG. 13, the basic time calculation unit 237
Is required for hardware operation and data transmission based on the above-described system configuration table 214, device information table 215 and transfer byte table 235, and seek count nsk and search count nsc obtained by the command analysis unit 233. The basic monitoring time ts is calculated. Further, the monitoring time adjustment unit 238 determines the monitoring time tw by adjusting the basic monitoring time ts based on the system configuration count Cs described later, sets the timer 413, and sets the timer 413 to perform the monitoring process by the input / output monitoring unit 412. It is configured to be used for.

Here, the basic monitoring time ts can be obtained as the sum of the operation time tmo required for the hardware operation and the transmission time ttr required for the data transmission. The operation time tmo is obtained as the sum of the total seek time tsk and the total search time tsc obtained by multiplying the positioning time τp and the rotation waiting time τc of the hard disk drive 432 by the seek count nsk and the search count nsc, respectively. On the other hand, the transmission time ttr is obtained by dividing the total transfer byte Bsc and the total transfer byte Bsd, which are the sum of the transfer byte Bc and the transfer byte Bd corresponding to each channel command word, by the channel transfer rate Rc and the device transfer rate Rd, respectively. Channel transfer time t obtained by
It is obtained by adding c and the device transfer time td.

Therefore, in step 308, the basic time calculator 237 determines the positioning time τp, the rotation waiting time τc, the channel transfer rate Rc and the device transfer rate Rd stored in the device information table 215.
By substituting the seek count nsk, the search count nsc, the total transfer byte Bsc, and the total transfer byte Bsd into the formula, the basic monitoring time ts may be calculated and provided to the processing of the monitoring time adjusting unit 238.

[0065]

[Equation 1]

Further, the monitoring time adjustment unit 238 holds a function indicating a change corresponding to a change in the number of devices of the system configuration coefficient corresponding to various system configurations, and in step 309, the system described above is held. It suffices to find a suitable system configuration coefficient Cs from the configuration table 214 and these functions, multiply it by the basic monitoring time ts described above, and set the multiplication result as the monitoring time tw in the timer 413.

For example, as shown in FIG. 16, regarding the system configuration of the combination in which the number of channel control units and the number of disk control units are changed, the graph is obtained by plotting the system configuration coefficient corresponding to the change in the number of disk drives. The system configuration coefficient Cs suitable for the system configuration may be obtained. When the monitoring time tw thus obtained is set in the timer 413, the transmission processing unit 218 shown in FIG. 11 causes the channel control unit 421 designated in step 310 to specify the series of channel command words described above. It may be sent to the auxiliary storage device 430 via the.

In this case, an appropriate monitoring time is set in the timer 413 in consideration of various factors such as presence / absence of cache, time required for hardware operation, and the number of bytes of data transmitted in each section in detail. Has been done. Therefore, the input / output monitoring unit 412 can reliably determine whether or not the hardware is operating normally, depending on whether or not there is an interrupt from the auxiliary storage device 430 within this monitoring time tw. .

This makes it possible to reliably measure the time from the issuance of the series of channel command words described above to the notification of the interrupt from the auxiliary storage device 430, so that various system configurations and tests can be performed. The input / output processing performance of the information processing system can be properly evaluated by flexibly responding to the conditions. By the way, in the disk cache, in order to improve the hit rate, when one track is an access target, the contents of tracks consecutive to this track are continuously read from the hard disk drive and loaded into the cache memory. There is a mode to keep, it is called the dynamic cache mode.

By using the track information held in the track information holding unit 236 described above, when this dynamic cache mode is applied, it is possible to calculate the monitoring time in consideration of its effect. In this case, the device information collection unit 212 collects dynamic cache application information indicating whether or not the dynamic cache mode is applied as a part of the device information of the disk control unit 431, and via the table creation unit 213. The function of the device information collecting means 125 described in claim 7 is realized by holding the same in the device information table 215, and is used for the processing of the cache judgment processing part 231 corresponding to the judging means 131.

At this time, the cache determination processing unit 23
1 is configured to correct the hit determination of each channel command word based on the track information corresponding to the immediately preceding channel command word held in the track information holding unit 236 according to the dynamic cache application information. Good. For example, as shown in FIG. 17, after the processing of step 314 of the cache determination processing described above is completed, the cache determination processing unit 231 determines, in step 316, based on the device information of the corresponding disk control unit 431 that the dynamic cache It is determined whether or not the mode is applied, and a hit determination correction process described later is performed according to the affirmative determination. On the other hand, in the case of a negative determination, step 315 is directly performed.
The processing may be performed and the processing may be ended.

In response to the affirmative determination at step 316 described above, the cache determination processing section 231 first, based on the track information held in the track information holding section 236,
It is determined whether the track that the channel command word of interest is accessing is expected to be loaded into the disk cache by the dynamic cache mode (step 317).

At this time, the cache determination processing unit 231
May determine whether or not the track specified by the corresponding channel command word is a track continuous with the track indicated by the track information described above. Also,
In response to the affirmative determination at step 317, the cache determination processing unit 231 determines that the hit determination result corresponding to the corresponding channel command word is a hit and corrects the contents of the hit / miss table 232 (step 31
8) After that, the process of step 315 may be performed to end the cache determination process.

As described above, based on the information indicating whether or not the dynamic cache mode is applied and the track information indicating the track designated by the immediately preceding seek command, the cache determination processing unit 231 causes the above-mentioned steps 316 to 316. By performing the processing of 318, the functions of the second usage determining means 137 and the modifying means 138 described in claim 7 are realized, and the effect of applying the dynamic cache mode is hit / miss table 232 and the monitoring time It can be reflected in the calculation process.

Further, it is possible to test the checking function by the error check code and the ability to restore from the overrun state in the state where the data check and the channel overrun are intentionally generated. For example, as shown in FIG. 18, the monitoring time calculation unit 217 is added to the data check detection unit 2
41 and an overrun detection unit 242 are added, and each of these units detects the occurrence of a parity error and the occurrence of a channel overrun phenomenon based on the input channel command word string, and outputs the detection result as the basic time. The configuration may be used for the processing of the calculation unit 237.

The data check detecting section 241 corresponds to the error detecting means 151 described in claim 11, and, for example, whether or not a parity error has occurred in the data indicated by the input channel command word. Based on the above, the number of data checks nch may be counted, and the counting result may be sent to the basic time calculation unit 237. Further, the overrun detection unit 252 corresponds to the overrun detection unit 153 described in claim 12, and, for example,
The number of overruns nov is counted based on whether or not a channel command word whose transfer unit is less than or equal to a predetermined number of bytes is continuously input for a predetermined number or more, and the count result is sent to the basic time calculation unit 237. Good.

In this case, for example, the data restoration time τdr required when a data check occurs and the restoration time τre required when an overrun phenomenon occurs are stored in the disk controller in the device information table 215. 431
It may be stored as information regarding the test conditions corresponding to a and 431b. Further, the basic time calculation unit 237 may calculate the basic time in consideration of the data restoration time τdr, the recovery time τre, the number of data checks nch and the number of overruns nov described above.

Specifically, the total data restoration time τ obtained by multiplying the data restoration time τdr by the number of data checks nch
dt and the total recovery time τrt obtained by multiplying the recovery time τre by the number of overruns nov, respectively, to calculate the correction time calculation means 152 and the recovery time calculation means 153 described in claims 11 and 12. Each function should be realized. Also, this total data restoration time τdt
And the total recovery time τrt obtained by the above equation
Claim 11 and Claim 12 by adding to s
The function of the adjusting means 129 described in 1 above is realized, the basic time ts1 corresponding to the occurrence of the data check and the occurrence of the overrun is obtained, and the basic time ts1 may be sent to the monitoring time adjusting unit 238.

As a result, not only can various system configurations be dealt with, but also various test conditions such as occurrence of data check and occurrence of channel overrun can be flexibly set and an appropriate monitoring time can be set. It is possible to reliably evaluate the input / output processing performance under these test conditions.

[0080]

As described above, according to the inventions of claims 1 and 3, different input / output request commands for accessing the same recording medium via different paths are stored differently based on the system configuration. Since the area can be automatically allocated, the occurrence of a read error due to interference from other test programs can be prevented, and the operation of the auxiliary storage device can be evaluated properly.

Further, the inventions of claims 2 and 4 to 13 are based on the information on the system configuration and the performance of the individual hardware constituting the system.
Since it is possible to finely correspond to various conditions and calculate appropriate monitoring times for use in monitoring the input / output processing operation, it is possible to reliably determine the success or failure of the operation of the auxiliary storage device.

As described above, according to the present invention, the operation test of the auxiliary storage device can be flexibly performed in correspondence with the configurations of various information processing systems to be tested.
The labor required for the development work of the test program can be significantly reduced, and the operation test of the auxiliary storage device can be efficiently advanced.
