HSG80 ACS Solution Software V8.6 for Windows NT and Windows 2000 Installation and Configuration Guide

Configuration Procedures 5–19
The partition number appears in the first column, followed by the size and starting
block of each partition.
4. Assign the partition a unit number to make it accessible by the hosts. See “Assigning
Unit Numbers and Unit Qualifiers” on page 5–19.
For example:
The commands to create RAID1, a three-member RAIDset, then partition it into two
storage units are shown below.
ADD RAIDSET RAID1 DISK10000 DISK20000 DISK10100
INITIALIZE RAID1
CREATE_PARTITION RAID1 SIZE=25
CREATE_PARTITION RAID1 SIZE=LARGEST
SHOW RAID1
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
Compaq StorageWorks HSG80 Array Controller ACS Version 8.6 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
