RAID splitting
Ensure that your system is in full working order and the RAID hardware
configuration is set up properly as described on page 142.
Split the RAID before you install software upgrades (PEPs). If you are
performing a platform upgrade or migration, refer to the Upgrade and
Platform Migration Guide (555-7101-207) for complete instructions.

To split the RAID

1Load the MegaRAID console. Select Start > Programs > Power
Console Plus > Launch Client.
2Ensure that Access Mode > Full Access is selected.
3Click OK.
Result: The MegaRAID Power Console Plus window appears.
4Ensure all drives are in ONLINE state (marked green).
5In the Physical Devices section, right-click the first drive (A01-2-
Onln).
6Select Tools ➝ Fail Drive from the shortcut menu.
Result: A message appears advising that marking the online drive
Failed results in changes.
7Ignore the warning and click OK. The drive status changes to
FAILED and the color of the icon changes to red (for example, A01-

ATTENTION As an extra precaution, Nortel recommends that you
perform a full system backup prior to performing a RAID-
split. For more information about system backups, see the
CallPilot Manager online Help.
