Raid 1 Failure Replacement Procedure
I have a PowerEdge R320 with 2 SAS hard drives configured as raid 1, controller is Perc H710 Mini. One drive is in a failed state what is the procedure to replace? Do I just remove the failed drive and insert the new one?
Thanks

Hello Tony92,
When we have a predictive fail drive that is still an online member of the array, there are 2 things that should be done before pulling and replacing: Using OpenManage Server Administrator (OMSA) or the controller BIOS.
1.Consistency check:
In OMSA: Expand Storage>expand controller. Select ‘Virtual Disk’. Choose ‘Check Consistency’ from dropdown and Execute.
2.When completed consistency check then Put drive offline before replacing:
In OMSA: Expand Storage>expand controller>expand connector>enclosure>select physical disks (or array disks). Select the drop down next to hard drive , choose offline and execute.
The rebuild should start automatically once the drive is replaced. If it does not then you can use OMSA or PERC BIOS to set the replacement drive as a hot spare that will make the rebuild begin.

Hello @steamedhomer,
The procedure is fairly simple, yes, after a failed disk has been identified, just remove the failed drive and insert a new one. Before you do it, it is advisable to have a full data backup. Do confirm that the drive has failed, either by LED status or OMSA logs or from PERC BIOS. Do remember to replace the drive similar to the DPN# as the failed drive, it is recommended, to avoid any complicated issue rise.
