Verifying consistency on the drives
This optional consistency check on the logical drive of the RAID system
ensures that the data on the drives is identical. If any errors are found,
they are corrected automatically. Nortel strongly recommends that you
do a consistency check before you split the RAID system pack. If
possible, perform the consistency check the day before the scheduled
maintenance. A good data backup on an offline drive is important if you
need to revert to the CallPilot system from an unsuccessful upgrade or
update.
Note: The consistency check can take up to 2 hours to complete and has
no significant impact on system performance.

To perform a consistency check

1In Windows, click Start > Programs > Power Console Plus >
Launch Client.

dialog box appears.

displaying the Logical View of the Physical Devices and the Logical
Devices. The status bar at the bottom of the window indicates that
RAID channels are being scanned. When scanning is done, the
screen refreshes and the Physical and Logical Devices screen
appears.
3In the Logical Devices section, right-click the logical drive, and then
choose Check Consistency from the shortcut menu.
