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.

Result: The MegaRAID Power Console Plus Server Selection dialog box appears.

2Ensure that Access Mode > Full Access is selected, and click OK.

Result: The MegaRAID Power Console Plus 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.
