Goal: Since the system disk is a RAID 1 mirrored set, we can rebuild the shadow set by replacing one of the good sets with a blank disk

Steps

• Shutdown and power down server
• Remove the disk from bay 9, which is part of the system shadow set. Put this disk on the shelf

• Insert blank/old disk into the empty bay

Label the new disk before inserting it into the empty bay

• Power up server
• During the booting process, the following message appears: “Some configured disks have been removed from your system…”

 

 

 

Press ‘C’ to Load Configuration utility

Press 'Y' to confirm to load the foreign configuration

• In this example, the system shadow set is Disk Group 2.  (Before proceeding, confirm this is the disk group in your case).  Expanding the physical disks shows a disk in bay 8 and a missing disk in bay 9.  This is correct.   Now, we have to include the new inserted disk in this group

RAID controller reporting bay 9 is empty

• There may be times when the new disk is seen as a foreign disk.  In this case, do the following:

Foreign disk is reported in bay 9

• CTRL-N (Next Page) to Foreign Mgt
• All the disk groups will be displayed.  Typically, the disk group containing the foreign disk will be grey. 
• To remove the foreign disk
  • Highlight Controller
  • Press F2
  • Select Foreign
  • Select Clear (do NOT import the configuration!)

Clear the foreign configuration

• Now the disk can be brought into the system shadow set disk group as a hot spare

• To include the newly inserted disk into the system shadowset disk group, it must be brought in as a hot spare
  • Highlight Disk Group 2 (VD Management)
  • Hit F2
  • Select 'Manage Ded. HS'

Manage dedicated hot swap

• Select the disk in bay 9 (Hit space bar to select)
• Tab to 'OK'. 
• Hit the return key

Select hot spare to bring into RAID 1 mirror set

• Rebuild automatically commences
