Using SWCC to Specify LUN ID Alias for a Virtual Disk
Setting a LUN ID alias for a virtual disk is the same as setting a unit identifier. To
set the LUN ID alias for a previously created virtual disk, perform the following
procedure:
1. Open the storage window, where you see the properties for that virtual disk.
2. Click on the Settings Tab to see changeable properties.
3. Click on the
Enable LUN ID Alias button.
4. Enter the LUN ID alias (identifier) in the appropriate field. It is strongly
suggested that, for simplicity, the LUN ID alias match the virtual disk number.
Note: If, while using the StorageWorks HBA, you create a unit after your server is
online, you must run the
SaveCfg command to see the unit.
Preferring Units
In multiple-bus failover mode, individual units can be preferred to a specific
controller. For example, to prefer unit D102 to “this controller,” use the following
command:
SET D102 PREFERRED_PATH=THIS
RESTART commands must be issued to both controllers for this command to take
effect:
RESTART OTHER_CONTROLLER
RESTART THIS_CONTROLLER
Note: The controllers need to restart together for the preferred settings to take effect.
The RESTART this_controller command must be entered immediately after the
RESTART other_controller command.
