Hi,

I have a file server with a IBM EXP 400 scsi direct attached storage expansion unit containing 6 disks and configured as raid 5 with a IBM serveraid 6M controller.  This unit can support 14 disks.

How can I add more disks in this unit and expand the raid 5 capacity without affecting the actual data

In most cases of direct attached storage you will not be able to add disks to an existing Raid5 with data on it.  It really all depends on the management software of the array.  If your IBM EXP400 came with a management utility, try checking that to see if you can add drives to your array.  Be very careful though, if it does let you expand the capacity it might destroy any existing data on it.

Another alternative might be to create a second Raid5 with the newly added disks and present it to your server.
