HP XP P9000 Command View Advanced Edition Suite Software 7.6.1-00 Administrator Guide (Web Version)

• 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). Note that if you
manage copy pairs defined in a snapshot group, the S-VOL does not need to be recognized
by the hosts.
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. Note that if you manage copy pairs defined in a snapshot group, the
host that recognizes the S-VOL does not need to 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:
Before you manipulate the copy pair from the Device Manager GUI or CLI, check
whether authentication mode is enabled for the command device that is connected
to the host (application server). If so, you must execute the raidcom -login
command on the host to authenticate yourself.
• If the OS of the host is Windows, you must be authenticated as the user who
executes the Device Manager agent service (HBsA Service).
• If multiple command devices in the same storage system are connected to the
host, enable the authentication mode for all of the command devices.
If you perform user authentication for the storage system once, you can access
all of the command devices in the same storage system.
• When the command device's authentication mode status is changed from dis-
abled to enabled, if there is another host that recognizes the command device,
also perform user authentication on that host.
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)
• A shared resource group in which a command device has been registered must be created
and assigned to each user.
Note that, if each user uses a different command device, register the command device in a
resource group managed by the user, instead of registering it in a shared resource group.
