Smart Array P420i controller replacement

hphp-prolianthp-smart-arrayraid

I have two identical servers with Smart Array P420i
One server has 4 physical drives, which form 2 logical drives (2 + 2 raid 1)
Second server also has its raid configuration with two physical drives (one logical drive, raid 1)
I put 4 drives from server one to free slots in server two and see

logicaldrive 1 (1.8 TB, RAID 1, OK)

  physicaldrive 1I:1:1 (port 1I:box 1:bay 1, Solid State SATA, 2 TB, OK)
  physicaldrive 1I:1:2 (port 1I:box 1:bay 2, Solid State SATA, 2 TB, OK)

unassigned

  physicaldrive 1I:1:3 (port 1I:box 1:bay 3, Solid State SATA, 1 TB, OK)
  physicaldrive 1I:1:4 (port 1I:box 1:bay 4, Solid State SATA, 1 TB, OK)
  physicaldrive 2I:0:5 (port 2I:box 0:bay 5, Solid State SATA, 500 GB, OK)
  physicaldrive 2I:0:6 (port 2I:box 0:bay 6, Solid State SATA, 500 GB, OK)

So, my controller sees drives, but set them as unassigned though they formed logical drives in the same controller on other server.

Can I somehow save my data and make current server to recognize existent logical drives.

  • Why did you move the drives?
  • Did you keep the drives together and in the same order?
  • What does the array setup look like on the original server?
  • Did you move one Logical Drive at a time?

If you missed some of these steps, all bets are off :(
