Unable to detect a faulted disk that is brought online after some time
A disk that fails temporarily and is brought online later is not detected by the operating system as the logical device for that disk is still in a failed state. (IA-31660)
Workaround:
To recover the disk, bring the logical device online.
- To view the failed logical device, use the ssacli ctrl slot=0 ld all show command.
- To bring the failed logical device online, run the ssacli ctrl slot=0 ld number_of_failed_ld modify reenable forced command where number_of_failed_ld is the ID of the failed logical device.
