OMSA Add new disk and convert current single disk to RAID1

dell-poweredgeraidstorage

We got our new server last week, and unfortunately one of the two disks could not be delivered. Now we've got the second disk, and I want to install it and join it with the current disk to create a RAID1 virtual disk.

Specs:

  • Server: Dell PowerEdge R620
  • RAID Controller: PERC h710 Mini

My questions are as follows:

  1. Can I just insert the disk without shutting down?
  2. Is it possible to do this through the OMSA UI?
  3. Can I do this without loosing the data currently on the single disk?

As you might have guessed, I'm not an IT-pro (I'm a developer actually), so I might have missed some vital info here. If so, please point it out!

Thanks in advance

You can insert the disk, if your system is hot-pluggable (R620 should be).

If you set up your single disk as raid1 with a failed second member, you just need to insert the second disk.

If you did it any other way things will get more complicated, but - yes, you can rebuild raids online using OMSA.

So again yes, you can do it without loosing data on the existent single disk.

Apart from that: Backing up systems to external storage should always be done in a professional environment.
