Converting a Dual Controller
Array to a Single Controller Array
If one controller fails in
a dual array controller configuration, you might want to run a single
controller for an extended period of time so that the array does not display
as degraded in the console.
- Make sure you know the serial
number of the controller being removed. You can check the event log
for the failed controller's serial number or check the console and make
a note of the primary controller's serial number.
- Change the remaining controllers
redundancy setting to disabled.
You must use the firmware application to disable redundancy on the controller.
Refer to the SANnet II RAID Firmware Users Guide for your
array for information about accessing the firmware application, and
then continue with the following steps.
- From the Main Menu,
select view and edit Peripheral devices, and press Return.
- Select Set Peripheral
Device Entry, and press Return.
- Select Redundant Controller
Primary, and press Return.
- Select Disable redundant
controller, and press Return.
- Stop the Agent as explained
in the installation chapter for your operating system.
- Change to /var/opt/DotHill/ssagent
and edit the file sscontlr.txt.
The very last line in the file contains the serial numbers of both controllers.
Remove the failed controllers serial number from this line.
# RAID_CONTROLLER=Enable:3197861:3179746
- Start the agent as explained
in the installation chapter for your operating system.
- Rescan the console if it
was open during this procedure.
