performance degradation, since different physical disks are used for read and write
operations on source volumes and the replica.
To set disk group pairs, use the omnidbsmis command. See the omnidbsmis man
page for command syntax and examples of manipulating the disk group pairs
configuration file. The file template is as follows.

NOTE:
After instant recovery, if you use the “switch” restore method, the disk group of your
snapclones become the disk group of the newly restored source volumes. This may have
a large impact on application performance in cases where performance characteristics
of the disk groups are different.
Configuration of backup system
As part of a ZDB session, Application Recovery Manager performs necessary
configuration steps, such as configuring volume groups, filesystems, mount points on
the backup system. Based on the volume group, filesystem, and mount point
configuration on the application system, Application Recovery Manager may create
the same volume group and filesystem structure on the backup system or can mount
to the mount points specified in the backup specification.
Before running backup sessions, you need to ensure that the host representing the
backup system is configured on the EVA storage system. If the backup system is not
configured, configure it manually. If the hostname on the EVA storage system is
