Upgrading Hard Drive Capacity

You can increase the storage capacity on a system by swapping drives one at a time
for higher capacity drives. This method is viable as long as a fault-tolerance method
is running, and can be done even if there are no available drive bays.
CAUTION: Since a data rebuild takes about 15 minutes per gigabyte, your system is
unprotected against drive failure for many hours, or even days, while the rebuild is in
progress.
To upgrade hard drive capacity:
1. Back up all data.
2. Replace any drive. The data on the new drive is re-created from redundant
information on the remaining drives.
3. When data on the new drive has been rebuilt (the Activity LED is no longer
illuminated), repeat the previous step for the other drives in the array, one at a
time.

CAUTION: If a 1785 (Not Configured) POST message is displayed, power the
system down immediately to avoid data loss, and then return the drives to their
original locations.
CAUTION: Do not replace any other drive until data rebuild on this drive is
complete.
