Replace DL380 RAID 5 drive with a drive from another DL380 RAID 5 server

[smocit]

I have a failing drive that needs to replaced. I have 2 DL380's with a RAID 5 configuration. Both have the same hard drive model numbers. Both servers were in use and have an OS installed.

Can I pull a drive from the DL380 I am not using and swap it with the failing drive in the DL380 I am using?

Sure, as long as you don't mind breaking the redundancy on the server you're "borrowing" a drive from.   If you don't have spare drives on hand, I can understand that you probably have priorities on which server is more important, and that's the one that needs the drive.

Anyway, you should have no problem pulling a drive from one server and putting it in the one with the failed drive.  It will detect it as a replacement and rebuild onto it.  That's assuming it's a compatible part number and all of that, which you say it is.

Just make sure you replace the drive you borrowed if that other machine is still important enough that it needs the redundancy.
