The configuration is as follows:
13 x 450G disks on RAID5 with 1 hot spare.
There 2 more disks but configured as RAID1.
Is it possible to upgrade the hard disks without downtime or data loss?

Looks like only M1115 supports hot swap and M5015 does not.

What is it that you are trying to achieve by replacing the hot spare with a larger drive? Are ok doing this offline since your RAID controller does not support hot swap. Your RAID may not allow expanding one drive with a larger capacity since they expect them to be of equal capacity.– ChidaAug 20, 2012 at 11:59

Updating the capacity of the SAN without downtime. Is it possible to do this with an expansion unit?– pl1nkAug 20, 2012 at 12:02

If this is your SAN then I strongly recommend you spek to IBM support and seek advice. This controller supports 32 SATA/SAS drives. You may also add an expansion unit but I'm unsure if you can do this without downtime.– ChidaAug 20, 2012 at 12:38
