Target ID FC Loop ID—You may need to change the FC Loop ID if you want the SM module to be at a
specific address or if your system checks addresses in reverse order (lowest address first).
You have two options:
• SOFT—Use this setting if you do not care whether the SM module’s Loop ID changes
when you power down and power up. This setting lets the FC loop initialization process
determine the Loop ID.
• Any number between 0 and 125—Select a specific number if you want the Loop ID to
stay the same after you power down and power up. The Disk Array Administrator
software cannot tell you which Loop IDs are available. To be sure that you have
successfully assigned the Loop ID you want, check the Loop ID after you restart the SM
module. If the SM module cannot get the specified Loop ID during the loop initialization
process, it will try to get a soft address.

Information on
page 196.
Each SM module has one LUN that you can change when you configure the host channels.
You only need to assign a CAPI LUN if you are using CAPI to configure the Galaxy 65
Subsystem over a host channel via SCSI protocol extensions.
If you are not using CAPI, you can set the CAPI LUN to NONE. If you are using CAPI, you
can set it to a value of 0-63.
You have two options for setting the LUN:
• NONE—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 CAPI LUN to
stay the same when you restart (this change takes effect immediately unless the CAPI
LUN is currently in use).
