HP XP Racks - Manual (Page 18)

NOTE: A source volume exchanges the role with a target volume by the Auto LUN operation.
However, the access attribute of the source volume and the target volume does not exchange.
You can set the access attribute to the source volume or the target volume of Auto LUN with Volume
Retention. However, if the emulation type of volume is 3390-A, and you set the Read Only attribute
or the Protect attribute to the source volume or the target volume, the migration operation may stop
or the failure may occur.
You can set all access attributes that you can set by using Volume Retention to the reserved volume
of Auto LUN. The access attributes that you can set by using Volume Retention are Read/Write,
Read Only, and Protect.
Compatible XRC pair volumes
You cannot create migration plans by using the Compatible XRC pair volumes as the source volume
or the target volume. You can create the Compatible XRC pairs by specifying the Auto LUN volumes
after creating the migration plan, but the Auto LUN process stops.
Concurrent Copy (CC) pair volumes
You cannot create migration plans by using the Concurrent Copy (CC) pair volumes as the source
volume or the target volume. You can create the Concurrent Copy pairs by specifying the Auto
LUN volumes after creating the migration plan, but the Auto LUN process stops.
