6 Setup for managing copy pairs
This chapter discusses the following setup requirements:
• Server requirements for managing copy pairs
• Host requirements for managing copy pairs
• Disk array requirements for managing copy pairs
• Creating configuration definition files for XP RAID Manager
6-1 Server requirements for managing copy pairs
This section describes the requirements for the Device Manager server to manage copy pairs.
• You can use Device Manager to control copy pairs in one of two ways:
○ Local management, with each host managing the copy pair(s) for the LUs recognized by
that host, or
○ Central management, with a single host managing all of the copy pair(s) for the LUs
recognized by multiple hosts. The
server.agent.rm.centralizePairConfiguration property file for the Device
Manager agent must be set to enable.
• The disk arrays that are candidates for P-VOL or S-VOL must be managed by a single Device
Manager server.
• When local management is used, the Device Manager server must recognize the hosts that
manage copy pairs.
6-2 Host requirements for managing copy pairs
This section describes the host requirements for operating copy pairs when local management is
used and when central management is used. If you have not yet created a copy pair, in the following
explanation you must read P-VOL as P-VOL candidate and S-VOL as S-VOL candidate:
Figure 6-1 shows a configuration example of operating copy pairs when local management is used.
