You can set only Read/Write as the access attribute to the reserved volume of Auto LUN. You
cannot set the Read Only, Protect, and S-VOL Disable attributes.
Volumes having access attribute of Volume Retention
You can select a volume setting an access attribute by using Volume Retention as a source volume.
However, depending on the access attribute of the target volume, you may not be able to perform
the Auto LUN operations. For the information about whether or not you can perform the volume
migration operation to the volume having the access attribute of Volume Retention, see
Table 13 (page 20). For the information about whether or not you can set the reserve attribute to
the volume having the access attribute specified with Auto LUN, see Table 14 (page 20).

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.
