 error description: 
  The current operation is not allowed because the controller has data in cache for offline or missing virtual drives.  
 
 Code: 0x54

Cause

Virtual disk configuration has not been deleted correctly from the RAID controller. To confirm, please use the GetPreservedCacheList command to see which virtual disk is failing.

 MegaCli64 
 -GetPreservedCacheList -aALL                                     
 
Adapter #1
 
Virtual Drive(Target ID 11): Missing.
 
Exit Code: 0x00

Workaround

First, discard the missing virtual disks configuration:

 MegaCli64 
 -DiscardPreservedCache -L11 -a1                                     
 
Adapter #0
 
Virtual Drive(Target ID 11): Preserved Cache Data Cleared.
 
Exit Code: 0x00

Then configure the RAID:

 MegaCli64 
 -CfgLdAdd -r0 [32:10] -a1                                     
 
Adapter 0: Created VD 11
 
Adapter 0: Configured the Adapter!!
 
Exit Code: 0x00
