Figure 6-1 Example of pair operations when local management is used
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 recognizes a command device.
• Device Manager agent must be installed on the hosts that recognize the P-VOL or S-VOL, and
a command device.
If there are multiple hosts that recognize the P-VOL, a Device Manager agent only needs to be
installed on one of the hosts. Similarly, if there are multiple hosts that recognize the S-VOL, a
Device Manager agent only needs to be installed on one of the hosts.
For details on the correspondence between copy pair operations and required Device Manager
agent versions, see
Table 6-1.
• XP RAID Manager must be installed on the hosts that recognize the P-VOL or S-VOL, and a
command device.
If there are multiple hosts that recognize the P-VOL, XP RAID Manager only needs to be
installed on one of the hosts. Similarly, if there are multiple hosts that recognize the S-VOL, XP
RAID Manager only needs to be installed on one of the hosts.
For details on how to install XP RAID Manager, see the relevant manual for XP RAID Manager.
