RAID splitting 135
What to do How to do it
Full data
backup
Do a full data backup before RAID splitting is performed as an extra precaution.
RAID splitting
Note: Because
the 703t has only
one physical drive
per channel, the
RAID splitting can
be done using
the Windows
MegaRAID
console without
risk of CallPilot
database
corruption.
1. Load the Windows MegaRAID console. Ensure all drives are in ONLINE
state (GREEN).
2. Right click the Channel 2 first drive (i.e (0) A1-2-Onln).
Select Tools → Fail Drive. A warning message will pop-up. Ignore it and
press OK. The drive status will change to FAILED and the color of the icon
should change to RED. The alarm should start beeping.
Note: The alarm can be silenced, but under no circumstances should it be
disabled. Select Adapter → Alarm Control → Silence Alarm
Technically the drive that is marked FAILED is now the Backup Drive.
Perform Call
Pilot software
upgrade
Let the system boot. The system will still run after Channel 2 of the RAID
card was taken out of service and will boot to Windows. Perform the software
upgrade.
RAID synching
for upgrade
successful
WITHOUT shutting down the server, in the Physical Devices section of the
MegaRAID console, right click the Channel 2 first drive (i.e Channel 2 (0)
A1-2-Failed). From the right mouse pop-up menu select Rebuild. When
Rebuild is done, the drive status will change to ONLINE and the color of the
icon should change to green. The alarm should stop beeping unless it was
temporarily silenced. The process can take up to one hour. DO NOT shut
down the machine before the rebuild is complete. If you do reboot or power
down during this process, you need to do ’RAID synching for upgrade NOT
successful’, then start again. You can monitor the rebuild by opening the
Windows MegaRAID console.
RAID synching
for upgrade
NOT successful
If the software upgrade has failed, the system needs to be returned to the
original configuration.
1. Restart the server and enter the Ctrl+M utility.
2. Select Objects → Physical Drive → FAIL Drive for the drive on Channel
1.The drive will show as FAIL after this step.
3. Select the drive on Channel 2 (previously taken offline or the Backup drive)
and make it ONLINE. Ignore the warning message.
At this point the drive on the Channel 2 is ONLINE and the one on Channel
1 is marked FAILED.
4. Exit the utility and reboot. 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. At this time, you can silence
the alarm but DO NOT disable it.
