Dell Unity: Unable to Resume or Retry a Paused Software Upgrade

摘要: A Dell Unity OE upgrade may fail to resume after being paused if management services switch to a different Storage Processor (SP) than the one holding the upgrade files. Reboot the active SP so the SP containing the upgrade image becomes primary, then retry or resume the upgrade. ...

症狀

The Unity OE upgrade is paused because Automatically Reboot Storage Processors was not selected. When attempting to resume the upgrade, Unisphere UI displays a Reload message and the upgrade does not continue.

service@(none) spa:~$ uemcli -u admin -p xxxxx /sys/soft/upgrade resume

Operation failed. Error code: 0x6000cb9
The system encountered an unexpected error while upgrading the software. Reboot your Primary storage processor and try upgrading again. Check System > Logs for related messages. (Error Code:0x6000cb9)

原因

The upload binaries are in the wrong SP. There was a switchover of management services from the time "Upgrade image" was uploaded and "Resume" operation was attempted.

解析度

Review the /EMC/CEM/log/cemtracer.log file for entries similar to the following:

service@(none) spa:/EMC/CEM/log$ grep "papi_get.sh tasks_info" *log
cemtracer.log:02 Aug 2017 23:03:36  - [UpdateProvider] FATAL - {0:x:x}[x|x|x][createJob @ ../../../components/providers/osls/UpdateProvider/src/C4CB_SoftwareInstallationService.cpp:1123] createJob exception: Failed to get tasks info: caused by the error in P-API backend (error running 'papi_get.sh tasks_info Unity-4.2.0.9392909.tgz.bin' meta (nil): request error code: 9, command error code: 0x100)

This error indicates that the upgrade cannot continue because the system is unable to retrieve the upgrade task information. Typically, this occurs when the upgrade files reside on one SP, while management services are running on the peer SP. For example, the upgrade files may be located on SPB, while SPA is currently hosting the management services. This condition can occur after an SP reboot, failover, or other event that changes the active SP.

Resolution

Reboot the SP currently running the management services (SPA in this example) so that the SP containing the upgrade files (SPB) becomes primary again. Once the correct SP is active, the Resume or Retry operation should succeed.

 

Note: This behavior was addressed through enhancements in Unity OE 4.3.x and later releases, reducing the likelihood of upgrade resume failures caused by management service failovers between Storage Processors.
