Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments herein without making any creative effort, shall fall within the scope of protection.
It should be noted that the terms "first," "second," and the like in the description and claims herein and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments herein described are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.
In the prior art, a tape unit fault warning mechanism is incomplete, whether the tape unit is available or not cannot be judged timely and accurately, generally, part of abnormal tape units can be solved through restarting or determined after the tape unit loses connection or backup operation fails, and part of abnormal tape units need to be replaced, so that the replacement of the tape units is passive, and preventive active replacement cannot be achieved.
To solve the above problems, embodiments herein provide a tape drive management method capable of improving accuracy of preventive replacement of a tape drive. Fig. 1 is a schematic diagram of steps of a tape drive management method provided in an embodiment herein, and the present specification provides the method operation steps as described in the embodiment or the flowchart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual system or apparatus product executes, it can execute sequentially or in parallel according to the method shown in the embodiment or the figures. Specifically, as shown in fig. 1, the method may include:
s101: acquiring the working data of a tape unit, wherein the working data comprises the total amount of read-write tapes and the total read-write duration;
s102: calculating to obtain a consumption value of the magnetic tape unit according to the working data of the magnetic tape unit and by combining a preset calculation function, wherein the preset calculation function is a function established by utilizing the working data of the magnetic tape unit and the consumption value;
s103: judging whether the tape unit needs to be replaced or not according to the consumption value of the tape unit and a preset critical value;
s104: and if the magnetic tape unit is judged to be required to be replaced, replacing the magnetic tape unit.
It can be understood that, in this document, the operational data of the tape drive is used as the parameters of the consumption calculation of the tape drive, so as to calculate the consumption value representing the life state of the tape drive itself, and thus, the operational state of the tape drive itself can be determined in real time, and then, according to the preset critical value and the calculated consumption value, whether the tape drive has a potential safety hazard or not is judged, and further, when the potential safety hazard exists, the preset active replacement is performed, so that the backup operation failure caused by the tape drive failure is reduced, and the backup efficiency is improved.
The total amount of the read-write magnetic tape is the total amount of all the read-write magnetic tapes in the working process of the magnetic tape unit, and as the total amount of the read-write magnetic tape increases, the hardware wear of the magnetic tape unit becomes more and more serious, the sensitivity of a magnetic head is reduced, and the service life consumption of the magnetic tape unit also increases, so that the total amount of the read-write magnetic tape of the magnetic tape unit can reflect the service life condition of the magnetic tape unit to a certain extent. In addition, because the working efficiency (such as the read-write efficiency) of different (types of) magnetic tape units is different, the total amount of read-write magnetic tapes and the total read-write time in the whole life process of one magnetic tape unit are different to a certain extent, for example, if the read-write efficiency of some magnetic tape units is higher, the total amount of read-write magnetic tapes is more in the whole process or a certain time period, and the total read-write time is less, so that the consumption value of the magnetic tape unit is calculated by establishing a function of the total amount of read-write magnetic tapes and the total read-write time according to the self characteristics of different magnetic tape units, and the self life consumption condition of the magnetic tape unit is further represented, and the magnetic tape unit can be replaced preventively and actively.
In this embodiment, as shown in fig. 2, the acquiring the tape drive operating data includes:
s201: acquiring an inspection log of a tape unit, wherein the inspection log comprises identification of read-write tapes and time length of each reel of tape in the tape unit;
s202: and determining the total tape reading and writing amount and the total reading and writing time length of the tape unit according to the polling log.
The polling log is configured to check the work records of the magnetic tape drive according to a preset period, for example, record an identifier of each time the magnetic tape is read and written by the magnetic tape drive, and a time length of each reel of magnetic tape in the magnetic tape drive, where the total number of the magnetic tapes read and written by the magnetic tape drive, that is, the total number of the read and written magnetic tapes, can be determined by each time the identifier of each time the magnetic tape is read and written, and the total time length of all the read and written times of the magnetic tape drive can be calculated by the time length of each reel of magnetic tape in the magnetic tape drive, and the preset period is set according to an actual situation, for example, the work records of the magnetic tape drive can be obtained by checking once a week in a manual checking manner.
In a further embodiment, the length of time each tape reel is in the tape drive is accessible to and accessible from the tape drive via the tapeIs calculated, e.g. the time of the tape entering and exiting the tape drive is T1And T2If the time length of the magnetic disk in the tape unit is T, T is the time length of the magnetic disk in the tape unit2-T1. Therefore, after the time length of each reel of magnetic tape in the magnetic tape unit is obtained, the total time length of reading and writing of the magnetic tape unit can be obtained by adding all the time lengths.
In an embodiment of this specification, the obtaining, by calculation, a consumption value of the tape drive according to the tape drive operating data in combination with a preset calculation function includes:
determining a type of the tape drive;
matching the preset calculation function according to the type of the magnetic tape unit;
and bringing the working data into the preset calculation function, and calculating to obtain the consumption value of the tape unit.
In a further embodiment, the matching the preset calculation function according to the type of the tape drive includes:
determining a first preset weight value of the total amount of the read-write magnetic tape and a second preset weight value of the total read-write time according to the type of the magnetic tape unit, wherein the first preset weight value and the second preset weight value are added to be 1;
and determining the preset calculation function according to the first preset weight value and the second preset weight value.
It can be understood that, according to different types of tape drives, different weight values are set for the total amount of the read-write tape and the total read-write time, and then a corresponding preset calculation function is established, so as to realize the calculation of the consumption value of the tape drive. The specific weight of the total amount of the read-write magnetic tape and the total time length of the read-write magnetic tape in the preset calculation function can be represented by setting different weight values, that is, different proportions are set according to the read-write efficiency of different magnetic tape units, and the specific consumption condition of the corresponding magnetic tape unit can be accurately determined, wherein the weight values set differently for the total amount of the read-write magnetic tape and the total time length of the read-write magnetic tape are set according to actual conditions, and are not limited in the embodiments of the present specification.
In the embodiment of the present specification, the preset calculation function is:
Sx＝Qx*α+(Tx/t0)*β， (1)
wherein S isxConsumption value, Q, of tape drive xxTotal read and write tape amount, T, of tape drive xxTotal read-write duration, t, of tape drive x0The time length of a single disk read-write of a tape unit x is preset, alpha is a first preset weight value, beta is a second preset weight value, and alpha + beta is 1.
Note that t in the formula (1)0The preset time for reading and writing a single disk of the magnetic tape unit x can be a designated value, for example, the designated value can be selected according to the theoretical working efficiency of the magnetic tape unit when the magnetic tape unit x is actually designated, and the higher the theoretical working efficiency is, the smaller the designated value is; the lower the theoretical operating efficiency, the larger the specified value. In some other embodiments, the t0The historical average efficiency of the tape drive may also be the historical average efficiency, that is, the total read-write tape amount and the total read-write time of the full life cycle of the historical failed tape drive are obtained by obtaining the historical failed tape drive corresponding to the tape drive type, and then the t corresponding to the tape drive type is determined0That is, the t is obtained by dividing the total read-write duration of the whole life cycle of the tape drive with the total read-write tape amount0Of course, to increase t0The reliability of the calculation can be selected from a plurality of history fault tape units, and t of each history fault tape unit is calculated0And further through a plurality of t0Average value of (1) to obtain the final t0。
In the foregoing step, the determining the first preset weight value of the total amount of the read-write tape and the second preset weight value of the total time length of the read-write tape according to the type of the tape drive as shown in fig. 3 optionally includes:
s301: determining a first initial weight value of the total amount of the read-write magnetic tape and a second initial weight value of the total read-write time according to the type of the magnetic tape drive;
s302: acquiring historical routing inspection logs of historical fault tape drives of the same type;
s303: determining the total amount of historical read-write tapes and the total historical read-write duration in the historical fault tape drive according to the historical routing inspection log;
s304: and adjusting the first initial weight value and the second initial weight value according to the total amount of the historical read-write magnetic tape and the total historical read-write time length so as to obtain the first preset weight value and the second preset weight value.
The accuracy of determining the service life consumption of the different types of tape drives can be improved by determining the first preset weight value and the second preset weight value corresponding to the different types of tape drives, the types can be produced by different manufacturers, different models, different use scenes, production batches and the like, and the specification is not limited. The first initial weight value and the second initial weight value are set according to actual conditions, and in order to facilitate quick adjustment of different types of tape drives, both the first initial weight value and the second initial weight value may be set to 50%, and of course, other setting manners are also possible, which is not limited in the embodiments of the present specification.
In this embodiment of the present specification, the first initial weight value and the second initial weight value are adjusted by historical data, so that the adjusted weight values can be ensured to be closer to actual values, and thus the obtained calculation function is more accurate and reliable, optionally, in the process of adjusting the weight values, the adjusted weight values are adjusted according to a specific gravity relationship between the total amount of the read-write magnetic tapes in the history failure magnetic tape unit and the total read-write time duration, for example, when the total amount of the read-write magnetic tapes in the history failure magnetic tape unit is larger, it indicates that the read-write speed of the magnetic tape unit is fast in actual work, and the total read-write magnetic tapes account for more than the total read-write time duration in the life consumption calculation process; when the total read-write time in the history fault magnetic tape drive is longer, the fact that the read-write speed of the magnetic tape drive is lower in actual work is shown, and the total read-write time accounts for being larger than the total read-write magnetic tape in the service life consumption calculation process.
Therefore, optionally, the adjusting the first initial weight value and the second initial weight value according to the total amount of the historical read-write tapes and the total time length of the historical read-write tapes to obtain the first preset weight value and the second preset weight value includes:
when the total amount of the historical read-write magnetic tapes exceeds a first threshold value and the total time of the historical read-write magnetic tapes does not exceed a second threshold value, adjusting the first initial weight value and the second initial weight value according to a first adjustment rule;
and when the total amount of the historical read-write magnetic tapes does not exceed a first threshold value and the total historical read-write time exceeds a second threshold value, adjusting the first initial weight value and the second initial weight value according to a second adjustment rule.
It can be understood that, in this step, the weight value to be adjusted is determined according to the actual conditions of the total amount of the historical read-write magnetic tape and the total duration of the historical read-write magnetic tape, where the first threshold and the second threshold are set according to the actual conditions, and the first adjustment rule is to increase the first initial weight value and correspondingly decrease the second initial weight value; the second adjustment rule is to reduce the first initial weight value, correspondingly increase the second initial weight value, and obtain different preset weight values by adopting different adjustment rules according to the size relationship between the total amount of the different historical read-write tapes and the total duration of the historical read-write tapes, so that different preset calculation functions can be established according to different types of tape machines.
For example, the first threshold may be 200, the second threshold is 10h, and when the total amount of the history read/write magnetic tape is determined to be 300 by the history inspection log and the total duration of the history read/write magnetic tape is 8h, the first adjustment rule range is satisfied, at this time, the first initial weight (for example, 50%) may be adjusted to 60%, and the second initial weight (for example, 50%) may be adjusted to 40%, that is, the first preset weight is 60%, and the second preset weight is 40%. When the total amount of the history read-write magnetic tape is determined to be 100 through the history routing inspection log, and the total time length of the history read-write magnetic tape is 12h, the second adjustment rule range is met, at this time, the first initial weight value (for example, 50%) may be adjusted to 40%, the second initial weight value (for example, 50%) may be adjusted to 60%, that is, the first preset weight value is 40%, and the second preset weight value is 60%; when the total amount of the historical read-write magnetic tape and the total time length of the historical read-write magnetic tape are not in the above range, designating the first initial weight value as the first preset weight value, and designating the second initial weight value as the second preset weight value. The above is only one way of adjusting the first initial weight value and the second initial weight value in the embodiments of the present specification, and there may be other ways, which are not limited in the embodiments of the present specification.
It should be noted that, in order to improve the accuracy and reliability of the adjustment of the initial weight value of the magnetic tape units, multiple groups of history faulty magnetic tape units in the same type of magnetic tape units may be selected, and abnormal data (such as data with sudden change) in the multiple groups of history read-write magnetic tape units and the total history read-write duration are removed by acquiring the total amount of the history read-write magnetic tape units and the total history read-write duration, and then the final total history read-write magnetic tape units and the total history read-write duration are determined by calculating the average value of the preprocessed data, so as to perform the adjustment; in some other embodiments, the initial weight values of each group of data of the magnetic tape drive with the history failure may also be adjusted in sequence to obtain a plurality of groups of adjusted preset weight values (for example, a plurality of groups of first preset weight values and a plurality of groups of second preset weight values), and then the final first preset weight values and the final second preset weight values may be determined by averaging.
In a further embodiment, in the process of adjusting the initial weight value, the initial weight value may be determined according to a relationship between a first difference between the total historical read-write tape amount and the first threshold value, and a second difference between the total historical read-write tape length and the second threshold value, as optionally:
determining a first change rate of the total historical read-write tape amount and the first threshold value, and a second change rate of the total historical read-write time and the second threshold value;
determining the larger absolute value of the first change rate and the second change rate, and marking the larger absolute value as a target change rate;
determining an initial weight value and an adjusting method corresponding to the target change rate;
and adjusting the initial weight value according to the adjusting method and the target change rate.
For example, the first threshold may be 200, the second threshold is 10h, the total amount of the historical read/write tapes is 300, the total duration of the historical read/write tapes is 8h, then the first change rate (total amount of the historical read/write tapes-first threshold)/first threshold) (300-, for example, if the number of the tapes is increased by 4% in an equal difference manner, the adjusted first preset weight value is 50% + [ (300-.
Therefore, the adjusting method can be an adjusting mode set according to an equal difference, equal ratio or a designated mode, so that the first initial weight value and the second initial weight value can be adjusted in a targeted mode, and the accuracy of calculating the service life consumption of the tape drive is improved.
In the embodiment of the present specification, the critical value may be understood as the critical point of the life of the tape drive, that is, the consumption value obtained by counting the total amount of the read/write tapes and the total duration of the read/write in the life cycle of the tape drive. Alternatively, the preset critical value is obtained by:
acquiring a history routing inspection log of a history fault magnetic tape unit;
determining the total amount of historical read-write tapes and the total historical read-write duration in the historical fault tape drive according to the historical routing inspection log;
and calculating to obtain a preset critical value of the magnetic tape unit according to the total historical read-write magnetic tape amount and the total historical read-write duration by combining a preset calculation function.
It can be understood that, through the analysis of the historical tape drive with failure, the life value of the tape drive of the type can be determined (i.e. the calculated value through the preset calculation function), and the life value is used as the working critical value of the tape drive of the type, so that the active replacement can be effectively carried out preventively, the failure shutdown is avoided, the continuity of backup is improved, the timeliness of operation and maintenance is improved, and the method has great practical value.
Alternatively, the preset critical value is obtained by the following formula (2):
S0＝Q0*α+(T0/t0)*β， (2)
wherein S is0For a predetermined threshold value, Q, of the tape drive0Reading and writing the total amount of tape for the history of the tape drive, T0Total time of history read/write, t, for the tape drive0The method is characterized in that the preset duration of reading and writing a single disk of a magnetic tape unit is represented by alpha which is a first preset weight value, beta which is a second preset weight value, and alpha + beta which is 1.
In a further embodiment, since there may be individual differences among the tape drives, and the life of the tape drives may fluctuate around a critical value, in order to improve the use range and reliability of the critical value, a tape drive replacement threshold value is determined as a replacement value, and the tape drive replacement threshold value is lower than the critical value, so that it can be determined that more tape drives can be replaced in time by the replacement threshold value, wherein the replacement threshold value may be 80% -95% of the critical value, and preferably, S is set1＝S090% of where S1For changing threshold values of tape drives, S0Is a preset critical value of the tape drive.
Alternatively, since the preset critical value represents the maximum service life value of the tape drive, the difference between the preset critical value and the consumption value can be used as the remaining life of the tape drive, and a life safety value can be further set, wherein the remaining life of the tape drive is lower than the life safety value to ensure that the tape drive is within the normal operating performance range, and the life safety value is set according to actual conditions, such as a certain proportion, preferably 10%, of the total life of the tape drive (the preset critical value).
In practice, there may be a scenario where multiple sets of tape drives are operating simultaneously, and a preferred replacement tape drive may be determined by comparing tape drive consumption values, for example, taking two tape drives a and b as an example, if A, B represents the total amount of tape read/write for tape drive a and tape drive b, respectively, and Δ t represents the time duration in the tape drive per reel, the time t that can be entered in the tape drive per reel can be determined by the time t that each disk is entered in the tape driveIntoAnd a time of departure tGo outTo obtain, TA、TBThe total time for reading and writing is represented as:
a is 1+1+1 … … +1 (a total),
b is 1+1+1 … … +1 (total of B),
Δt＝tgo out-tInto，
The comparison results are output by data arrangement of the magnetic tape a and the magnetic tape b as the following table 1:
TABLE 1
| Magnetic tape unit (a, b) | TA＞TB | TA＝TB | TA＜TB |
| A＞B | Change a | Change a | Further judgment |
| A＝B | Change a | Both are equal to each other | Change b |
| A＜B | Further judgment | Change b | Change b |
Further, although the magnetic tape unit a and the magnetic tape unit b are the same type of magnetic tape unit, there is a certain difference in actual operation, so that the magnetic tape units with large consumption values can be preferably replaced by calculating and comparing the corresponding consumption values, and the specific replacement process is not limited in this specification.
