DELL PERC 6/i Two VD's with multiple Disk Types, can't assign Hot Spare
All,
I have a situation with my current setup. I have two VD's and no extra disk slots on my chassis. One VD has 4 SAN Solid State Drives (Toshiba 1TB each), and all are active in RAID 5. The other VD is RAID 0 with two spinning disks (Seagate 159 GB each) and one disk failed. I have removed the failed disk from the VD and (TRIED) to assign a new disk of the same type as a hot spare. When I attempt to add the disk as a hot spare I get the 0xc error that says this drive will not cover any of my existing VD's. Does this have to do with the fact that I have two VD's each with a different disk type? Am I adding the new disk as a hot spare incorrectly? It looks like when you add a hot spare, it only gives you the option to (Make Global HS) This makes me think that you have to have all the same disk types, even if you have multiple VD's. Is this True?

Hi @Mr_Dalvin10,
It is always recommended to have a similar type of drives in a virtual disk but having different drive types among virtual disks will not be a problem.
The issue here is that in RAID 0 there is no redundancy in case of a drive failure. The entire data is lost and the virtual disk will be in an "OFFLINE" state.
When a virtual disk in RAID 0 fails, the only option is to delete the data on the remaining drive and re-create a new virtual disk.
Also, from the first picture that you posted, I can see the RAID status as "OFFLINE", you can only add a drive as hot-spare if the virtual disk is in an "OPTIMAL" or "DEGRADED" state and since the VD is in an offline state, the system won't accept a hot spare.

Thank you for the info Dheeraj. My main concern was the fact that I could not assign the disk as a hot spare at all and I did not correlate the fact that I was using RAID 0 and not RAID1. That was an unfortunate choice with this box but I remember I did it because it was a lab.
If the two disks were in RAID 1 then there should have been no issue removing the degraded disk, adding the new disk and assigning it correct?

Hi, yes you can do it as you mentioned that sounds good. Whilst you are replacing the faulty drive, pull out the drive, and wait for approx. 30 seconds, then insert the new drive. If rebuilding does not happen automatically, you can assign the drive as a hot spare.
