Good day
I am planning on doing MSA disk firmware updates but unit has had a hard drive that is degraded for a while now and the status is only showing as "monitor the disk".
I was wondering if when I do the disk firmware upgrades if this degraded disk will cause problems. Environment will be shutdown for the MSA disk firmware upgrades.
Perhaps should just go ahead and replace the degraded disk even though its not fully failed??
Thanks
Solved! Go to Solution.

Re: MSA2040 disk degraded - monitor disk
Hi
Remove the disk which is showing monitor or degraded out of the array by 1-2 inches.
I believe it's part of a RAID disk group which is FTOL (Fault tolerant and online).
You may verify the disk group status using the below command:
"show disk-groups"
The global spare will kick in and the rebuild will start on the disk group
Then you may want to follow MSA 2040 disk drive firmware update best practices:
тАв Disk drive upgrades on the HP MSA 2040 storage systems is an offline process. All host and array I/O must be stopped
prior to the upgrade.
тАв If the drive is in a virtual disk, verify that it is not being initialized, expanded, reconstructed, verified, or scrubbed. If any
of these tasks is in progress, before performing the update wait for the task to complete or terminate it. Also, verify that
the background scrub is disabled so that it doesnтАЩt start. You can determine this using SMU or CLI interfaces. If using a
firmware smart component, it would fail and report if any of the above pre-requisites are not being met.
тАв Disk drives of the same model in the storage system must have the same firmware revision. If using a firmware smart
component, the installer would ensure all the drives are updated.
Hope this helps.!!

Re: MSA2040 disk degraded - monitor disk
@Mahesh202 Hi Mahesh
Thanks for the response and advice, yes I see the Disk Groups is FTOL and there is Global Spares, but no 2TB Global spares though. The degraded disk is a 2TB disk.
Thanks

SolutionHi,
You could execute the below commands and verify whether the degraded disk is reporting unrecovered medium errors or large number of recovered errors.
show system
show events
You could verify the events through SMU as well.
If the error event count is high ,replace the hdd before firmware upgrade.
The array should be healthy before performing any firmware upgrade.
