Data path
When both systems are XP7, you can use multiple path groups. This is done by
registering path groups with multiple path group IDs in the same storage system.
But note that only one path group can be specified for a mirror. Up to eight paths
can be registered in one path group.
Groups of remote paths, which allows you to configure or change the configuration
of multiple paths at the same time.
Path group
•
A maximum of eight remote paths can be registered in a path group
•
A maximum of 64 path groups can be set in a storage system.
•
The range of values for the path group ID is 0-255.
•
For a mirror, the same path group ID must be used to connect the primary
storage system to the secondary system as is used to connect the systems in the
reverse direction.
•
The path group is specified during the create pair operation. It cannot be
changed by resynchronization or the swap operation.

Path groups can be created and specified using RAID Manager. See
