Replacing Hard Disk With A Previously Used Disk

atrerice — Mon, 01 Feb 2021 22:39:28 GMT

Hi,

I have a ProLiant DL360 Gen9 that has a failed disk. Controller is a SmartArray P440ar, one logical disk configured as RAID 10. The drive in question is a 600GB 10K SAS 2.5". I have several of these disks sitting in decommissioned servers and was wondering if I can just take one of those and hotswap with the failed one and will it just start rebuilding as it would if that disk was blank? Or, does it need to be zeroed out first? I have swapped many failed disks, but only with brand new ones.

Thanks in advance!

If you are sure that there is no data on old hard drives and it was already erased then go ahead.

Else better zeroed out first..so that any information written previously will be cleared and then replace.

No problem if you swap them online.

Don't swap them offline!

@Torsten. Will I need to zero out the drive first, or am I good to just use the drive full of data and swap it in and the system will take care of overwriting it?

If you put it in the running System, there is no need to clear the Drive.

Just put the old Drive in the Running System as a replacement and the rebuild should start automatically.
