Changing the Controller’s Target ID and LUN
You can change the controller’s target ID or LUN, if necessary:
!
Target ID—This is either the SCSI target ID for the G5312 or K5312 or the
controller’s FC Loop ID for the G7313 or K7313.
– SCSI target ID—You may need to change controller’s SCSI target ID when
you have existing devices at ID 1, the controller’s default, or when you are
adding more than one controller to a system.You can set the target ID to any
number between 0 and 15.
– FC Loop ID—You may need to change this if you want the controller 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 if the controller’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 reboot the controller. If the controller cannot get the
specified Loop ID during the loop initialization process, it will try to get a
soft address.
!
LUN—You only need to assign a controller LUN if you are using the
Configuration Application Program Interface (CAPI) to configure the controller
over a host channel via SCSI protocol extensions.
If you are not using CAPI, you can set the controller LUN to NONE. If you are
using CAPI, you can set it to a value of 0-7 or SOFT. If set to SOFT, the
controller LUN is automatically assigned a LUN value when the controller
boots. The soft LUN value will be assigned to the first available LUN (starting
from zero) that does not already have a hard (that is, a numeric) LUN
assignment.
You can have three options for setting the LUN:
– NONE—Use this setting if you are not using CAPI to configure the
controller (this change takes effect immediately).
– SOFT—Use this setting if you do not care if the controller’s LUN changes
when you reboot the controller.
