Figure 1-12 Example of pair operations when local management is used
From the P-VOL or S-VOL, LUN security must be set for the host.
LUN security from the P-VOL and S-VOL must be set for at least one host, although the host to
which LUN security from the P-VOL is assigned and the host to which LUN security from the S-
VOL is assigned do not need to be the same.
The host must recognize the P-VOL or S-VOL.
The P-VOL and S-VOL must be recognized by at least one host, although the host that
recognizes the P-VOL and the host that recognizes the S-VOL do not need to be the same.
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.
The host that recognizes the P-VOL or S-VOL must recognize a command device.
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 section
