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 S tate: System Warnin g”
+ “Warning: Single Controller”
NOTE. If you do not see the Single Contr oller warning message and the disk array continues to
display a System War ning, refer to the
Service Manual

line utility. The ARM utilities are installed with the AutoRAID Manager software. If the software has not been
