Select button
You can use the select button to select an item from a menu.
The select button and navigation buttons help you to navigate and select menu
and boot options, and start a service panel test.
The select button is located on the front panel of the SAN Volume Controller, near
the navigation buttons.
Node identification label
The node identification label on the front panel displays a six-digit node
identification number.
The node identification label is the same as the six-digit number that is used in the
svctask addnode command. It is readable by system software and is used by
configuration and service software as a node identifier. The node identifier can also
be displayed on the front panel display when node is selected from the menu.
If the service controller assembly front panel is replaced, the configuration and
service software displays the number that is printed on the front of the
replacement panel. Future error reports contain the new number. No cluster
reconfiguration is necessary when the front panel is replaced.
Error LED
Critical faults on the service controller are indicated through the amber, error LED.
The error LED has the following two states:
OFF The service controller is functioning correctly.
ON A critical service controller failure was detected and you must replace the
service controller.
