Figure 13 Example of a system configuration for managing copy pairs (configuration that uses a virtual
command device server)
• Application servers that recognize the P-VOL and S-VOL must be registered in the Device Manager
server.
• The P-VOL and S-VOL are managed by a single Device Manager server.
• From the P-VOL and S-VOL, LUN security must be set for the application server.
The virtual command device server does not need to recognize the P-VOL or S-VOL.
• Application servers must recognize the P-VOL or S-VOL.
We recommend that P-VOL and S-VOL be assigned to separate application servers. Note that the
P-VOL and S-VOL must be recognized by at least one application server each.
• 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.
• The virtual command device server must recognize a command device.
The command device security must not be used for 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)
• Device Manager agent version 7.1 or later must be installed on the application servers.
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.
