I have a Dell PowerEdge R530 running ESXi 6.0.0 Update 2 (Build 4192238).
It has 4 drives in a RAID10 on the PERC H730.
One drive went bad and of course the status switched to Degraded. I replaced the drive, the rebuild completed, and the DRAC now shows all 4 drives green and OK (not in rebuilding status, no predicted failures, all normal, etc), and the RAID10 itself is back to healthy (no longer showing degraded in the DRAC).
However, in ESXi it still shows as Degraded and I can't seem to find anything that will get it to go back to normal.
The array hasn't been in Degraded status (according to the DRAC itself) for well over 24 hours now.
I've tried rebooting the Host multiple times. I've even tried completely unplugging both PSU for about 10 minutes and doing a cold boot.
Is there some command you can enter in esxcli to force it to check/update the status of a disk that was previously reporting as degraded?
