Assigning a Unit Number to a Single (JBOD) Disk
To assign a unit number to a single (JBOD) disk, use the following syntax:
ADD UNIT UNIT-NUMBER DISK-NAME
For example:
To assign unit D4 to DISK20300, use the following command:
ADD UNIT D4 DISK20300
Assigning a Unit Number to a Partition
To assign a unit number to a partition, use the following syntax:
ADD UNIT UNIT-NUMBER STORAGESET-NAME PARTITION=PARTITION-NUMBER
For example:
To assign unit D100 to partition 3 of mirrorset mirr1, use the following command:
ADD UNIT D100 MIRR1 PARTITION=3
Preferring Units
In multiple-bus failover mode, individual units can be preferred to a specific controller.
For example, 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 for the preferred settings to take effect. The RESTART
other_controller command must be entered immediately before the RESTART this_controller
command.
