5.3.1 Viewing LUN Information
You can view information for each existing LUN.
To view LUN information:
1 From SAM, select Monitor Galaxy 65 Subsystem > Status > LUN Information.
The LUN Information page displays listing each existing LUN along with the node WWN, array name, and
partition name.
5.4 Changing Management LUNs
Each SM has a management LUN (also called the CAPI LUN) that you can change. These LUNs allow
the SM Configuration Application Programming Interface (CAPI) to configure the SMs. You need to
assign a management LUN only if you are using CAPI to configure the SM over a host channel using
SCSI protocol extensions. If you are not using CAPI, you can set the management LUN to NONE. If you
are using CAPI, you can set it to a value of 0-63.
Note Most UNIX, Linux, and Macintosh operating systems require that the management LUN be set to a higher
value than all array LUNs. Before creating your first array, change the management LUN to a higher
value. If you are using software that your company developed to configure and manage the controller (this
application uses CAPI to communicate with the controller), you must have a management LUN. If you are
not using software that your company developed, and therefore are not using CAPI, select NONE as the
management LUN. This allows your first array to be seen at LUN 0.
To change the management LUNs:
1 From SAM, select Manage Galaxy 65 Subsystem > LUN Management > Change SM LUN.
The Change SM LUN page displays.
2 Select the LUN you want to use for each SM:
Note:
Use this setting if you are not using CAPI to configure the Galaxy 65 Subsystem.
• Any number between 0 and 63: Select a specific number if you want the management LUN to stay
the same when you restart the Galaxy 65 Subsystem (this change takes effect following a shutdown
reboot).

5.5 Changing the Alarm Mute Setting
You can enable or disable the audible alarm that sounds when the Galaxy 65 Subsystem becomes too
hot, detects low or high voltage, or an array becomes critical or goes offline. Changing the mute setting
lets you turn off the alarm when it is sounding. You should turn it back on after resolving the problem.
You can also use the Mute button on the Galaxy 65 to turn off the alarm when it sounds.
The alarm sounds for temperature or voltage conditions (events). Warning events are generated when
the temperature or voltage enters the warning range. Shutdown events are generated when the
temperature or voltage enters the shutdown range. After reaching the shutdown range, the Galaxy 65
