hardware - HP array device fails after pci slot change

i changed my HP 410 smart array controller from one pci slot to another because it was faulty. After the change the logical unit i had fails showing one disk as unassigned and a new one into the array

Smart Array P410 in Slot 5                (sn: PACCRID11231CTT)

array A (SATA, Unused Space: 0 MB)

  logicaldrive 1 (931.5 GB, RAID 1, Interim Recovery Mode)

  physicaldrive 0:1 (box 0:bay 1, SATA, 0 MB, Failed)
  physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SATA, 1 TB, OK)

unassigned

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

Is there any way to change the failed physicaldrive for the unassigned? the physicaldrive 0:1 doesn't exist.

System is a Windows Server 2008

Thanks.

Answer

Since this is a RAID 1 (Mirror), your healthy disk physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SATA, 1 TB, OK) should be holding a complete copy of your data. I would remove this disk and ensure the data is backed up. Then delete the logical drive on the controller, reinstall 2 healthy disks, create a fresh array and copy the data back onto it.

I think this is the safest way, particularly if your controller is now giving incorrect information about the physical disks that are present, although this could indicate further hardware problems (disk bay backplane, controller).

Probably also worth taking the opportunity to update all firmware.
