Configuration Procedures 5–21
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
Assigning Unit Identifiers
One unique step is required when configuring storage units for OpenVMSSGI IRIX:
specifying an identifier (or LUN ID alias) for each unit. A unique identifier is required for
each unit (virtual disk). This identifier must be unique in the cluster.
This section gives two examples of setting an identifier for a previously created unit: one
using CLI and one using SWCC. The CLI uses the older terms “identifier” and “unit”,
while SWCC uses the terms “LUN ID alias” and “virtual disk”.
Identifier = LUN ID alias
Unit = virtual disk
Using CLI to Specify Identifier for a Unit
The command syntax for setting the identifier for a previously created unit (virtual disk)
follows:
SET UNIT_NUMBER IDENTIFIER=NN
