Description

Channel fault detection method, device and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a channel fault detection method, an apparatus, and a related device.

Background

The channel used by the host system is a connecting device for transmitting information and data, IO operation of the system, such as accessing a disk, and the like, and the data transmission process is realized through a physical fiber channel which is deployed in advance among devices. Once a channel fails, IO delay is caused, and finally, congestion of system operation transaction and other serious consequences are caused.

In the related art, the conventional way of handling the channel failure is usually passive handling, i.e. performing maintenance and replacement of the channel after the hardware failure of the channel until the channel is destroyed. However, in order to avoid incomplete transactions caused by sudden channel necrosis, a SYSTEM AUTOMATION tool (SA) is used to monitor channel exception information in SYSTEM log information, and when a single channel is found to report more than 5 errors in one minute of the same virtual machine (LPAR), the SA actively performs isolation operation on the channel. After the isolation of the fault channel is completed, the system can ensure the smooth operation of subsequent transactions due to the existence of other redundant physical connections.

Although the method can avoid the problem of transaction incompleteness caused by channel failure, the transaction execution speed is influenced in a window before channel hardware fails to completely realize isolation, and even transaction congestion is caused.

Therefore, the existing channel fault processing method cannot predict the time of hardware fault, and the hidden danger of safe and stable operation of the system is large due to a large influence range caused by fault.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein.

In order to facilitate understanding of the technical solution of the present invention, technical terms appearing in the present invention are explained:

a channel: a device for transferring information and data in a host system.

Operation: JOB, program for batch processing data.

Control-M: an automated scheduling tool.

REXX: a host programming language.

And SA: systemaautomation, a host system automation tool.

As known from the background art, the existing channel fault processing method cannot predict the time of hardware fault, and the hidden danger of safe and stable operation of the system is large due to a large influence range caused by the fault.

In the scheme, the channel operation data collected in the previous detection period is taken as the basis, the channel operation data collected in the current detection period is combined, the two channel operation data are compared, the channel fault levels of different connection sections of the physical optical fiber channel are judged according to the obtained comparison result, and corresponding channel fault maintenance is carried out, so that the time of hardware fault occurrence is predicted, the fault influence range is reduced, and the safe and stable operation of the system is guaranteed.

First, as shown in fig. 1, an architecture diagram of a channel fault detection system provided in an embodiment of the present invention is shown, where the channel fault detection system includes: the system comprises two physical hosts 11, two storage switches 12, physical disks 13, 4 monitoring modules 14, a channel health check module 15 and a channel fault early warning module 16.

In the host platform, the physical host 11 is physically connected with its peripheral devices through a channel.

Specifically, a physical fibre channel (logically referred to as an upstream channel) is deployed between the physical host 11 and the storage switch 12, so as to implement the interconnection requirement between the physical host 11 and the storage switch 12. A physical fibre channel (logically referred to as a downstream channel) is deployed between the storage switch 12 and the physical disk 13, so as to implement the interconnection requirement from the storage switch 12 to the physical disk 13, and a specific deployment effect can be seen in fig. 2.

It should be noted that, in actual deployment, in order to ensure a high availability target of a channel physical connection, a host usually accesses a physical disk by deploying at least 2 optical fiber connections of a storage switch, so as to prevent a single point failure problem of the optical fiber connections.

In fig. 1, with reference to fig. 2, in the operation process of the host system, in order to implement active routing inspection of the channel health state to complete active hardware maintenance in advance, monitoring modules 14 are deployed on 4 key connection segments of the host channel, that is, 4 monitoring modules 14 are deployed on each connection segment of the physical optical fiber channel, and are used to collect channel operation data in different connection segments of the physical optical fiber channel, that is, the number of packet losses of data transmission caused by optical attenuation.

Specifically, a monitoring module 14 is deployed on the physical host 11, and is configured to collect the number of data transmission packets lost due to optical fiber attenuation at the uplink port of the storage switch in the uplink channel, that is, to collect the number of packet losses at the uplink port of the storage switch.

A monitoring module 14 is deployed at an uplink port of the storage switch 12, and is configured to collect the number of transmission data packets lost due to optical fiber attenuation on a physical host side in an uplink channel, that is, to collect the number of lost packets on the host side.

A monitoring module 14 is deployed at a downlink port of the storage switch 12, and is configured to collect the number of data packets lost due to optical attenuation of an optical fiber at a physical disk port side in a downlink channel, that is, to collect the number of packet losses at the physical disk side.

A monitoring module 14 is deployed on the physical disk 13 side, and is configured to collect the number of transmission data packets lost due to optical fiber attenuation at the downlink port side of the storage switch in the downlink channel, that is, to collect the number of packet losses at the downlink port of the storage switch.

In other words, the 4 monitoring modules 14 specifically include: the system comprises a physical host side monitoring module, a storage switch uplink port monitoring module, a storage switch downlink port monitoring module and a physical disk side monitoring module.

Based on the above, it can be understood that the health check operation of the channel status is implemented by collecting the number of transmission data packets lost due to optical attenuation in different connection segments of the physical fiber channel by the plurality of monitoring modules 14 deployed on the whole physical channel link. After the specific connecting section of the channel with serious light attenuation is positioned, hardware maintenance personnel actively replace and maintain the connecting section which is likely to have faults according to the positioning, so that the rapid fault positioning capability is improved, the active maintenance of channel hardware is realized, and the influence on transaction caused by delayed treatment of passive maintenance after hardware problems are worsened is reduced.

The channel health check module 15 is deployed on the host system for collecting critical performance data for all channels in the host system during a particular period.

The critical performance data is specifically the number of transmission data packet loss caused by a connection segment of one channel due to light attenuation occurring in the connection segment, which is accumulated in two adjacent inspection periods, in other words, the critical performance data refers to the total number of transmission data packets caused by light attenuation occurring in different channels in specific time periods in different connection segments.

It should be noted that the specific period may be understood as a specific time period, and the specific time period, also called a health check time interval, may be determined and adjusted according to actual operating conditions of different host systems, such as an online transaction peak window, a night batch operating window, and the like.

In the embodiment of the present invention, 3 specific time periods are divided into 24 hours a day, specifically:

firstly, after the main batch of the host system is finished at night 3:30, at this time, the online transaction low peak is positive, and if the active routing inspection maintenance of the channel hardware is needed, the influence of the hardware maintenance operation on the online transaction can be reduced to the minimum;

second, 13 pm: 30, the active patrol is initiated at the moment, so that the running condition of the on-line service peak of the host system in the afternoon can be checked and confirmed in advance, and the reliability requirement of a large data updating amount window on the channel performance in the afternoon peak period is ensured;

thirdly, 21:30, after the host system goes through a daytime online transaction processing task, the online transaction peak value is already reduced, and the main batch does not start to operate at night, and the channel health check and the possible hardware maintenance operation are performed at the moment, so that the normal operation of the batch at night can be guaranteed.

In practical application, the channel health check module 15 uses an automatic scheduling tool CONTROL-M to schedule a check job flow according to a preset time point (which can be understood as the specific time period) to collect channel performance data, and collects packet loss data amount of each connection segment of each channel in the host system after a previous check point (which can be understood as a previous specific time period); and after the collection is finished, counting the packet loss amount of each connection segment of each channel through comparison operation, and judging the channel fault level according to a predicted monitoring threshold value.

It can be understood that, in the embodiment of the present invention, based on the inspection result data at the above one inspection time point, the data of the two inspection results are compared with each other in combination with the inspection result of this time, to determine whether the operation conditions of different connection segments of the optical fiber channel are degraded. If the total number of transmission data packets of a certain connecting section of a certain optical fiber channel, which are caused by light attenuation, in two adjacent check points suddenly increases, namely exceeds a preset threshold value, the connecting section of the channel is actively subjected to failure reporting processing, system personnel are prompted to pay attention to the problem, and then hardware maintenance operation of the channel is actively carried out by the hardware personnel.

The threshold value can be set according to the specific actual operation of the host system, and can be dynamically adjusted and optimized according to specific conditions after the host system operates for a certain period. If the set threshold value is too aggressive, namely channel hardware maintenance is carried out only by relatively low packet loss after two related health checks, the hardware maintenance workload can be increased, and the consumption of optical fiber consumables is too large; if the set threshold value is too wide, the aim of preventive screening of the possibly failed channel cannot be achieved, and preventive maintenance and replacement of the channel which really fails cannot be achieved.

The channel fault early warning module 16 is disposed on the host system, and configured to send a corresponding alarm according to the channel fault level information code output by the channel health check module 15.

Specifically, the result data after two inspections are compared by an automatic scheduling tool Control-M, if the result data exceeds a threshold value of a packet loss number set in advance, the result data is judged to be a high risk of the channel hardware fault, and if the result data does not exceed the threshold value set in advance, the result data is judged to be a low risk of the channel hardware fault.

After the channel hardware fault risk level is judged, the judgment result needs to be sent to a host system, and channel hardware maintenance operation is carried out by host system management personnel and hardware maintenance personnel.

In the embodiment of the invention, different message codes (which can be understood as information codes) are respectively set for the high risk and the low risk of the channel hardware fault, and after the automatic scheduling tool Control-M finishes the judgment of the channel hardware fault risk, the channel hardware fault low risk message codes or the channel hardware fault high risk message codes are respectively written into a system log according to the judgment result; and then capturing the message codes in the system log through a host system automation tool SA, and respectively sending main or secondary alarm information to system management personnel and hardware maintenance personnel according to the message code level. And the alarm information received by the system management personnel and the hardware maintenance personnel decides whether to carry out hardware maintenance operation and a specific implementation window.

Based on the channel fault detection system provided by the embodiment of the invention, the channel operation data collected in the previous detection period is taken as the basis, the channel operation data collected in the current detection period is combined, the channel operation data in two times are compared, the channel fault levels of different connection sections of the physical optical fiber channel are judged according to the obtained comparison result, and corresponding channel fault maintenance is carried out, so that the time of hardware fault occurrence is predicted, the fault influence range is reduced, and the safe and stable operation of the system is ensured.
