We got a T620 configured with RAID 5 ( 5 Disk + 1 Hot Spare). On RAID (Disk 00 - Disk 04) and Disk 05 is Dedicate Hot Spare.
Now Disk 00 & Disk 05 (Hot Spare) had failed.
Then the Disks was replaced (First with Disk 00) and then after 24hrs followed with Disk 05)
However it was then later found Disk 00 is on READY State and Disk 05 is on ONLINE State.
It appears that Disk 00 behaving like Hot Spare. How do I get back the Disk 00 to rebuild itself and become ONLINE and Disk 05 to be on READY state so that it can reconfigure it back to dedicated Hot spare?
If your RAID controller supports offlining then you can offline the drive and then set the other drive as a hot spare to initiate a rebuild. Once the rebuild starts you can set the other drive as a hot spare.
If your controller supports copyback then you can enable copyback so that the hot spare copies data to the replacement drive and goes back to being a hot spare. There is a link to the storage manual section of our site on our PERC page.
