HP XP P9000 Command View Advanced Edition Suite Software 7.6.0-00 Administrator Guide (Web Version)

• A host that recognizes the S-VOL
Host (application server) conditions:
• Device Manager agent must be installed on hosts as follows:
If there is one host that recognizes the P-VOL and one host that recognizes the S-VOL, install
a Device Manager agent on each of the hosts.
If there are multiple hosts that recognize the P-VOL and multiple hosts that recognize the S-
VOL, install a Device Manager agent on one of the hosts that recognize the P-VOL and one
of the hosts that recognize the S-VOL.
• RAID Manager must be installed on hosts as follows:
If there are multiple hosts that recognize the P-VOL and multiple hosts that recognize the S-
VOL, install RAID Manager on one of the hosts that recognize the P-VOL and one of the hosts
that recognize the S-VOL.
If the command devices recognized by a host support the authentication function, install version
01-25-03/01 or later of RAID Manager on the host.
• If there are multiple NICs on the host, the Device Manager agent and RAID Manager must
use the same IP address.
Copy pair (P-VOL and S-VOL) conditions:
• The P-VOL and S-VOL must be managed by a single management server (Device Manager
server).
• The P-VOL and S-VOL must be recognized by the hosts (application servers).
HP recommends that P-VOL and S-VOL be assigned to separate hosts.
• From the P-VOL or S-VOL, LUN security must be set for the host (application server).
From the P-VOL and S-VOL, LUN security can be set for different hosts.
Command device conditions:
• Both the host that recognizes the P-VOL and the host that recognizes the S-VOL must recognize
a command device.
• From a command device, LUN security must be set for the hosts that recognize the P-VOL or
S-VOL.
For a host that recognizes the P-VOL, LUN security must be set from the command device on
the P-VOL side. For a host that recognizes the S-VOL, LUN security must be set from the com-
mand device on the S-VOL side.
CAUTION:
If the host is connected to a command device whose authentication mode is enabled,
you need to authenticate users by executing the raidcom command on the host
before performing copy pair operations from the GUI or CLI. If the application
server OS is Windows, you need to authenticate users as a Device Manager agent
service (HBsA Service) execution user.
Resource group conditions (when managing partitioned resources in P9500):
• The volumes below, or a storage system containing the volumes below, must be registered in
a resource group managed by the user.
- P-VOL
- S-VOL
- All pool volumes that make up a pool (when managing Snapshot or Fast Snap pairs)
- All journal volumes that make up a journal (when managing Continuous Access Journal pairs)
