Please use the following workaround to repair disk00 when disk00 has key CDNFS data and can not be unused. This was found in VDS-IS version 2.5.11.
Below are the steps:
1) Use the cli shutdown poweroff
2) Remove disk00
3) Remove disk01 and place it into disk00's location (essentially swapping their location)
4) Power on the system
5) Allow some time ( so that CAL/UNS will rebuild the 'key drive' (symlink tree) onto the new disk00 - which was originally disk01 )
6) Use the cli show disk details , show cdnfs to confirm this
7) Re-insert the original disk00 into disk01's location
8) Reload the system; the original disk00 (now disk01) will be reclaimed as a SYSTEM drive but without any symlink tree
9) U can now unuse the new disk01 (which was the original disk00):
disk unuse disk01
10) Proceed with repairing disk01:
disk repair disk01
Note: ignore the RAID alarms that will be raised when disk00 is removed
