Hi experts,

We have 2 HP Proliant ML 350 G4. One one them is not in use and the other have a failed disk in a 3 disks RAID 5 array. Can I unplug a disk of the unused server and replace the failed disk on th other? The disk I wish to use from the unused server has format and data. Is it a problem?

Thanks.

Yes you can just swap it over.

Same capacity and disk speed?

Assuming the size and speed are the same, it will just prompt you when it is connected to rebuild the array, and it will blow away the data on the newly added drive.  You will go into the raid utility on boot and do the rebuild.

As noted above, if a windows server will see events in the system event log.

If the disk in the unused server is not part of an array in the unused server, but instead is a single volume, then you may have to first initialize it, or remove the existing single physical volume container, before it will be accepted by the array controller as a replacement.  

If the disk in the unused server is part of a multi-disk array that holds data then you don't have to do anything to it before you replace the bad drive with it.

Good Luck,
