HP StorageWorks P9000 Command View Advanced Edition Suite Software 7.1 Administrator Guide (web) (TB581-96050, May 2011)

We recommend that P-VOL and S-VOL be assigned to separate hosts. Note that the P-VOL and S-
VOL must be recognized by at least one host.
• 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 command
device on the S-VOL side.
• Both the host that recognizes the P-VOL and the host that recognizes the S-VOL must recognize a
command device.
• The volumes below must be registered in a resource group managed by the user.
The setting is required when managing partitioned resources in P9500.
• P-VOL
• S-VOL
• All pool volumes that make up a pool (when managing Snapshot 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.
The setting is required when managing partitioned resources in P9500.
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.
• 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.
For details on the correspondence between copy pair operations and required Device Manager
agent versions, see “Device Manager agent requirements for managing copy pairs” on page 53.
• 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 recog-
nize the S-VOL.
If the authentication mode for command devices recognized by a host is enabled, install version
01-25-03/01 or later of RAID Manager on the host.
For details on how to install RAID Manager, see the relevant manual for RAID Manager.
• If there are multiple NICs on the host, the Device Manager agent and RAID Manager must use
the same IP address.
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.
