I have the system drive in a mirror Raid 1+0, there are 2 72 GB drives.  I'd like to upgrade those with 2 146 GB drives.  Is there a non-destructive way to do this.  Can I take one of the 72 GB drives out and replace with the 146 wait for it to mirror and then take the other one out?

You can replace the drives with bigger ones one at a time and you must give the system enough time to do the mirroring completely before proceeding to the next disk. This procedure is not enough though. After all disks have been replaced, you need to use the HP ACU's expand utility to make the logical drive use the new extra space. And after that you need to use your OS-specific tools to utilize the new space either by creating new partitions or expanding the existing ones.

The above is correct but you will need battery backed write cache for logical drive extension to be enabled. You can also add more drives to the current array, but again only if you have BBWC.

Thanks.  Worked perfectly.  Widows 2008 handles the drive expansion alot smoother than 2003 did.
