• Details about mapping the primary and secondary storage systems to the external system that contains the in the HP XP P9000 Provisioning for Open Systems User Guide and HP XP P9000 External Storage for Open and Mainframe Systems User Guide. • Details about CLPR in the HP XP P9000 Cache Partition User Guide. • Details about external path groups in the HP XP P9000 External Storage for Open and Mainframe Systems User Guide. Prerequisites Before you begin, make sure you have: • Installed the multipath and system software (see "Installing and configuring software" (page 22)). Workflow Use the following process to configure the primary and secondary storage systems: 1. Stop Performance Monitor, if it is running, to avoid performance impact on the TCP/IP network. 2. Set the port attributes for ESAM. 3. Configure the primary and secondary storage systems and establish logical paths between the primary and secondary VSP systems. Configuring the quorum disks Configuring the quorum disk is the third main task in the system configuration. Completion of this task ensures that the disk is configured to be able to determine which pair volume has the latest (most current) data when automatic failover is required. This task involves configuring the disk and configuring port parameters for the disk on the primary and secondary storage systems. CAUTION: For data protection reasons, make sure that the disk is not shared by two storage systems. Prerequisites Before you begin, make sure you have: • Installed the multipath and system software (see "Configuring the primary and secondary storage systems" (page 23)). Procedure 1. In the external storage system, prepare a volume for use as the quorum disk and specify any required system options. 2. Using the External attribute, configure the ports on the primary and secondary storage systems that are connected to the disk. 3. Set the paths from the disk to the primary and secondary storage systems to Active. 4. Using RWC's Ports/Host Groups and External Storages windows, map the primary and secondary storage systems to the disk by doing the following: • Configure at least two cross-system paths between the primary storage system and quorum disk, and two between the secondary storage system and the quorum disk. • Specify the these external volume parameters: - Emulation type: OPEN-V. - Number of LDEVs: 1. 24 System configuration

Prerequisites
Before you begin, make sure you have:
•
Installed the multipath and system software (see
“Installing and configuring software”
(page 22)
).
Workflow
Use the following process to configure the primary and secondary storage systems:
1.
Stop Performance Monitor, if it is running, to avoid performance impact on the TCP/IP network.
2.
Set the port attributes for ESAM.
3.
Configure the primary and secondary storage systems and establish logical paths between
the primary and secondary VSP systems.
Configuring the quorum disks
Configuring the quorum disk is the third main task in the system configuration. Completion of this
task ensures that the disk is configured to be able to determine which pair volume has the latest
(most current) data when automatic failover is required.
This task involves configuring the disk and configuring port parameters for the disk on the primary
and secondary storage systems.
CAUTION:
For data protection reasons, make sure that the disk is not shared by two storage
systems.
Prerequisites
Before you begin, make sure you have:
•
Installed the multipath and system software (see
“Configuring the primary and secondary
storage systems” (page 23)
).
Procedure
1.
In the external storage system, prepare a volume for use as the quorum disk and specify any
required system options.
2.
Using the
External
attribute, configure the ports on the primary and secondary storage systems
that are connected to the disk.
3.
Set the paths from the disk to the primary and secondary storage systems to
Active
.
4.
Using RWC’s
Ports/Host Groups
and
External Storages
windows, map the primary and
secondary storage systems to the disk by doing the following:
•
Configure at least two cross-system paths between the primary storage system and quorum
disk, and two between the secondary storage system and the quorum disk.
•
Specify the these external volume parameters:
- Emulation type:
OPEN-V.
- Number of LDEVs:
1.
