Configuration Guide
Assigning Unit Numbers and Unit Qualifiers
Each storageset, partition, or single (JBOD) disk must be assigned a unit number for
the host to access. As the units are added, their properties can be specified through the
use of command qualifiers, which are discussed in detail under the
ADD UNIT command
in the StorageWorks HSG80 Array Controller ACS Version 8.7 CLI Reference Guide.
Because of different SCSI versions, refer to the section “Assigning Unit Numbers
Depending on SCSI_VERSION,” page 1–19. The choice for SCSI_VERSION effects
how certain unit numbers and host connection offsets interact.
Each unit can be reserved for the exclusive use of a host or group of hosts. See
“Restricting Host Access in Transparent Failover Mode,” page 1–21 and “Restricting
Host Access in Multiple-Bus Failover Mode,” page 1–24.
Assigning a Unit Number to a Storageset
To assign a unit number to a storageset, use the following syntax:
ADD UNIT UNIT-NUMBER STORAGESET-NAME
For example:
To assign unit D102 to RAIDset R1, use the following command:
ADD UNIT D102 R1
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
