OK, from what I've been seeing online (including at this link Repurpose spare drive in HP ProLiant RAID 5 array) it should be pretty simple to do what I need. I just want to get confirmation, since I haven't dealt with RAID arrays in years (when nothing like this was possible).
Basically, we have a ProLiant DL380 G7, running version 8.70.9.0 of the Array Config Utility. We have 2 arrays setup on it as: Array A - 2 600 GB drives in RAID 1
Array B - 5 600 GB drives in RAID 5
- 1 600 GB drive as a shared spare
The server itself is a Server 2008 R2 Hyper-V host, holding the DC, file server, and SCCM DP for a smaller site. However, the Hyper-V host is down to about 50 GB's of free space. What we were thinking as a temporary fix (until they can purchase a new server next year), is to remove the spare, and add it to Array B to increase the available space.
Again, from what I can tell online, removing the spare and adding it to and expanding Array B should all be possible while the server is running. Just Manage Spare Drives, uncheck the drive in Bay 8 (it looks like I need to uncheck it for both arrays?), then after that's done add it to Array B and extend it.
Can anyone tell me if I have any incorrect information or assumptions? Thanks in advance.
