Figure 36 Configuration for managing the primary volume and secondary volume from the same
server (without using Application Agent)

A copy group must consist of pair volumes for the same application. When a copy group consists
of more than one pair volume and there are pair volumes for different applications in the copy
group, an unexpected backup or restoration might be performed.

When using Business Copy, configure the pair volume in the storage system. When using Continu-
ous Access Software, configure the pair volume between the storage systems.

Application Agent operates the pair volumes for Business Copy, Fast Snap, Snapshot, Continuous
Access Software or Continuous Access Journal.

Application Agent cannot back up or restore volumes paired by Flex Copy or Auto LUN.

Depending on the version of RAID Manager, the model of the storage system, and the version of
the microcode, the functionality for acquiring the copy type of the pair volume (copy group) might
not be supported. Because of this, Application Agent might not be able to correctly recognize
whether the copy type of a pair volume (copy group) is supported, since the copy type cannot be
retrieved. Thus, if you configure a system in which Flex Copy pair volumes and Business Copy,
Fast Snap, or Snapshot pair volumes co-exist, since the Flex Copy pair volumes (copy groups) are
not supported, make sure that they are disregarded as backup or restoration targets, by locking
them with the drmcgctl command.

When using Continuous Access Software, do not enter an MU number in the MU# setting in the
RAID Manager configuration definition file (

horcm

n

.conf

). If

0

is defined for the MU# setting,

volume information for the Continuous Access Software pair will not be stored in the dictionary
map when you execute a

drm

XX

display

#

command with the

-refresh

option specified.

Therefore, the volume information cannot be displayed by the Application Agent command, and
the pair volume cannot be backed up.
