HP XP7 Command View Advanced Edition Administrator Guide (Web Version) (TK981-96004, May 2014)

CAUTION:
• If the HORCM_ALLOW_INST parameter is specified in the configuration definition
file on the virtual command device server, the default port number
(34000+instance-number+1) must be used for the RAID Manager initiator
port of the application server.
• 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 (virtual command device 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
virtual command device server, enable authentication mode for all of the com-
mand devices.
If you perform user authentication for the storage system once, you can access
all of the command devices in the same storage system.
- If the command device's authentication mode status is changed from disabled
to enabled, if there is another host that recognizes the command device, also
perform user authentication on that host.
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 application servers.
• From the P-VOL and S-VOL, LUN security must be set for the host (application server).
The virtual command device server does not need to recognize the P-VOL or S-VOL.
Command device conditions:
• The virtual command device server must recognize a command device.
The command device security must not be used for a command device.
• From a command device, LUN security must be set for the virtual command device server.
To manage copy pairs for Continuous Access or Continuous Access Journal, LUN security
must be set for the host, from the command devices of the storage systems of both the P-VOL
and S-VOL.
Resource group conditions (when managing partitioned resources in HP XP7 or 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 resource group in which a command device has been registered must be created and as-
signed to each user.
• Command devices whose storage system resource group ID is 0 (resource pools of the default
virtual storage machine in HP XP7) are connected to the host (virtual command device server),
