To synchronize RAID after an unsuccessful upgrade
If the upgrade or update has failed, the system needs to be returned to the
original configuration.
Step Action
1
Restart the server and enter the Ctrl+M utility when prompted during
system bootup.
2
From the Management menu select Objects and press Enter.
3
Select Objects → Physical Drive and press Enter.
4
Select FAIL Drive for the drive on Channel 1.
Result: The drive will show as FAIL.
5 Select the drive on Channel 2 (previously taken offline as the backup
drive and marked ’Failed’) and make it ONLINE. Ignore the warning
message.
Result: At this point, the drive on the Channel 2 is ONLINE and the
one on Channel 1 is marked FAILED.
6
Exit the utility and press Ctrl+Alt+Delete to reboot the server.
Result: The system will boot up to the original configuration before
the software upgrade and an audible alarm will indicate the state
CRITICAL for the drives. You can silence the alarm but DO NOT
disable it.
7
Once the system is fully booted, open the Windows MegaRAID
console and rebuild the FAIL drive on Channel 1 using the same
process indicated in "To synchronize the RAID after a successful
upgrade" (page 131). Reverting from a failed software upgrade is
now complete. The audible alarm, if left on, should automatically
stop.
