Suppressing Single-Controller Warning Messages
When a single controller disk array is powered 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 that 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”
To avoid future single-controller warning messages, you can suppress them using the arraymgr ARM
command line utility. The arraymgr utility is described in further detail in the System Administrator’s
Guide, which is shipped with each disk array.
