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
