HP StoreVirtual 4330 Hard Drive Upgrading
Like the title says I need to upgrade the drive capacity of the SAN. I'll be taking the 8x450GB SAS (currently in RAID6) drives out and replacing them with larger drives. I am unfamiliar with this process (and SANS for the most part) and wondering what all it entails. I know how to physically replace drives I'm just talking about within the configuration of the SAN what I need to do.
The SAN is running the StoreVirtual OS w/ HP StoreVirtual Centralized Management Console version 11.0. The data is all backed up on the companies BCS appliance so no worries there. I'd just like to know hopefully in a step by step manner what I need to do. Are there services and other things that need to be stopped prior to shutting it down and exchanging the drives etc? When I setup the new volumes how do I configure it so that my production server can see them (again I'm a SAN novice).
Thanks for any help here.

Okay great that makes since. Could you elaborate on how you get the storage attached to your server?
David - replace 2 drives in a RAID-6, What? that would leave all the data at risk of what is now a third drive failure and loss of all data!
Dustin, please make sure you have viable full backups before you start this process - dont forget "Schrodinger Backups: The condition of any backup is unknown until a restore is attempted"
If you just replace the 450GB disks with say 1TB, then after replacing the disks you can either expand the RAIDset and then the LUN, or create a new LUN from the spare space

Otherwise you replace 2 drives leaving 4 to replace, rebuild, replace 2 drives, rebuild, replace 2 drives, rebuild expand the lun, rebuilding is a disk intensive process and at any time a weak drive could fail on you
