Suppressing Single-Controller Warning Messages When a single controller disk array is turned on for the first time, the control panel may display a "System Warning" error message, which occurs because only one controller is installed. By default, the disk array assumes there should be two controllers installed, and therefore it will generate single-controller error messages until you suppress them. If a "System Warning" error message is displayed on the front panel, you must first verify that it is caused by the detection of a single controller. Use the control panel keys to verify the source of the message by using the following key sequence: KEY CANCEL CANCEL MENU - ENTER + DISPLAY "System Warning" "Language" "View Settings" "System State: System Warning" "Warning: Single Controller" NOTE. If you do not see the Single Controller warning message and the disk array continues to display a System Warning, refer to the HP SureStore E Disk Array 12H User's and Service Manual for assistance in interpreting the warning. To avoid future single-controller warning messages, you can suppress them using the arraymgr ARM command line utility. The ARM utilities are installed with the AutoRAID Manager software. If the software has not been installed on the host, refer to the HP SureStore E Disk Array 12H System Administrator's Guide for instructions. To suppress single-controller warning messages, type the following command from the host: arraymgr -J SingleController can contain the disk array serial number or an alias text string assigned to the disk array.

Suppressing Single-Controller Warning Messages
When a single controller disk array is turned on for the first time, the control panel may display a “System Warning”
error message, which occurs because only one controller is installed. By default, the disk array assumes there should
be two controllers installed, and therefore it will generate single-controller error messages until you suppress them.
If a “System Warning” error message is displayed on the front panel, you must first verify that it is caused by the
detection of a single controller. Use the control panel keys to verify the source of the message by using the following
key sequence:
KEY
DISPLAY
CANCEL CANCEL
“System Warning”
MENU
“Language”
–
“View Settings”
ENTER
“System State: System Warning”
+
“Warning: Single Controller”
NOTE.
If you do not see the Single Controller warning message and the disk array continues to
display a System Warning, refer to the
HP SureStore E Disk Array 12H User’s and
Service Manual
for assistance in interpreting the warning.
To avoid future single-controller warning messages, you can suppress them using the
arraymgr
ARM command
line utility. The ARM utilities are installed with the AutoRAID Manager software. If the software has not been
installed on the host, refer to the
HP SureStore E Disk Array 12H System Administrator’s Guide
for instructions.
To suppress single-controller warning messages, type the following command from the host:
arraymgr -J SingleController <array-id>
<array-id>
can contain the disk array serial number or an alias text string assigned to the disk array.
