Partition expansion.

Server 2003 SP2, HP Proliant, Raid 5, 641 Controller

I have recently added two drives to our raid 5 array. I expanded / extended the array via the HP array controller. Windows sees the new space as 'unallocated' in disk manager. It will allow me to allocate it to a new partition but not an existing one. i.e. we have a C and D partition and I want to expand D. Not add E.

Is this possible with disk manager or will it require additional software. Thanks.

    Not with Disk Manager - but you can via the command line with DISKPART - see:

    If its your production server, be very careful with DISKPART or anyother partioning utilities (e.g. Partiion Magic) . I highly recommend mailbox and configuration backups before progressing. I have successfully expanded partitions using Partition Magic few times on HP and Dell servers.

    Just take the backup and use any of the Partition Tools to re- partitioning C Drive.
