I'm running an HP ProLiant ML350 with an SA641 RAID controller with 6 hot plug SCSI disks.
The OS is Windows 2000 Server - SP4.
Array A = RAID 1 -> 2 mirrored disks for the system files (Logical disk C)
Array B = RAID 5 -> 3 disks in distributed parity for all data files (Logical disk D)
All disks are "Basic Disks".
I recently expanded the RAID 5 disk array to 4 disks, and then extended the Logical Disk D on this array through HP's ACU (Array Configuration Utility).
The operation succeeded, but when I go look in Win 2K's Disk Management, it turns out that the added space is marked as "unallocated space".
How can I add the extra free space to the Logical Disk D?
