• If there are multiple NICs on the host, the Device Manager agent and XP RAID Manager must
use the same IP address.
• XP RAID Manager must have fewer than 32 running instances.
Figure 6-2 shows a configuration example of operating copy pairs when central management is
used.
Figure 6-2 Example of pair operations when central management is used
When central management is used:
• From the P-VOL or S-VOL, LUN security must be set for the host.
The host does not need to recognize the P-VOL or S-VOL.
• From a command device, LUN security must be set for the host that centrally manages copy
pairs.
To manage the copy pairs for XP Continuous Access Software or XP Continuous Access
Journal Software, LUN security must be set for the host, from the command devices of the
storage devices on both the P-VOL and S-VOL.
• The host that centrally manages copy pairs must recognize a command device.
The command device security must not be used for a command device.
• Device Manager agent must be installed on the host that centrally manages copy pairs.
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 host that centrally manages copy pairs.
For details on how to install XP RAID Manager, see the relevant manual for XP RAID Manager.
