Re: Degraded disk group
Can you please provide the picture of all Global Spares by hovering your mouse pointer as marked below on top of each Global Spare so that drive details will pop-up like below one,
Hope this helps!

Re: Degraded disk group
Have you run your logs through the MSA HealthCheck? https://www.hpe.com/storage/MSAHealthCheck
I notice your drive firmware is downlevel this is not causing this problem.
Have you tried setting the spares back to available and then back again to SPARE?
Are the SPARE drives suitable replacements? Same or larger size and same type of drive?
One of the updated best practices (see HealthCheck) is to enable Dynamic Sparing which will also take AVAIL drives and use them as spares.

Re: Degraded disk group
HealthCheck:
Status Unhealthy Component Description Recommendation
Virtual Pool A The virtual pool is degraded. - Ensure that spare disks are available. Reconstruction should start automatically. - When the reconstruction is complete, replace the failed disk(s). (Look for event 8 in the event log to determine which disk(s) failed.) - Disk groups that cannot find compatible spares will automatically move data to fault-tolerant components.
Disk Group dgA02 The disk group is not fault tolerant. Reconstruction cannot start because there is no spare disk available of the proper type and size. - Replace the disk with one of the same type (SAS SSD, enterprise SAS, or midline SAS) and the same or greater capacity. For continued optimum I/O performance, the replacement disk should have performance that is the same as or better than the one it is replacing. - Configure the new disk as a spare so the system can start reconstructing the vdisk. - To prevent this problem in the future, configure one or more additional disks as spare disks.

Re: Degraded disk group
1.10 - EG1200JEHMC
1.5 - EG1200JEHMC
1.13 - EG1200JEMDA
1.24 - EG1200JEHMC
It seems no issue with drive models.
Next you can try deleting all Global Spares and make 1,5, 1.13 and 1.24 as AVAIL drives. Then configure Dynamic Spare. Follow below process,
https://support.hpe.com/hpesc/public/docDisplay?docId=c04220794 (page no 183)
With dynamic spares enabled, if a disk fails and you replace it with a compatible disk, the storage system rescans the bus, finds the new disk, automatically designates it a spare, and starts reconstructing the disk group.
If above still didn't work then try configuring only One Global Spare for example, 1.5 or 1.24. Rest two drives leave it as AVAIL drives.
If still it's not working then log a HPE Support case,
https://support.hpe.com/hpesc/public/docDisplay?docId=cep-help_en_us&page=index.html
Hope this helps!

Re: Degraded disk group
I have finished with settings, but no luck with isuue resolving.
We replaced disks with new one model - EG001200JWJNQ. Does it fit with MSA 2040 or incompatible, because still no changes...

Re: Degraded disk group
It looks to me supported model only as per below supported drive firmware link,
https://support.hpe.com/hpesc/public/swd/detail?swItemId=MTX_e4af5736d2d743bc836ba7bee4
You go ahead and log support case with HPE.
Hope this helps!

Re: Degraded disk group
Hi SUBHAJIT
I have same issue, Disk Group dgB02 - Degraded ,and HPE support advice me reboot the controller, but I have too much workload, production, can you help for an other cli command run rescan disks or way I can restart Reconstruction opration. also advise do I rescan disk channel so it will impact running SAN status.
System Health
Degraded
Reason:
A subcomponent of this component is unhealthy.
Unhealthy Components
Virtual Pool B - Degraded
A virtual disk group is missing one or more disks.
- Ensure that spare disks are available. Reconstruction should start automatically.
- When the reconstruction is complete, replace the failed disk(s). (Look for event 8 in the event log to determine which disk(s) failed.)
- Disk groups that cannot find compatible spares will automatically move data to fault-tolerant components.
Disk Group dgB02 - Degraded
One disk in the RAID disk group failed. Reconstruction cannot start because there is no spare disk available of the proper type and size.
- Replace the disk with one of the same type (SSD, enterprise SAS, or midline SAS) and the same or greater capacity. For continued optimum I/O performance, the replacement disk should have performance that is the same as or better than the one it is replacing.
- Configure the new disk as a spare so the system can start reconstructing the disk group.
- To prevent this problem in the future, configure one or more additional disks as spare disks.
- If the disk group is being expanded, reconstruction will start after the expansion is complete.
