You can also set access attributes for BC P-VOLs, S-VOLs, and reserve volumes. For BC pair
operations and reserve attribute change operations after access attribute setting, see the following
tables.

NOTE:

The Data Retention access attributes of volumes do not change as a result of BC operations.

Even though the Quick Restore operation reverses the P-VOL and S-VOL, the access attributes of
the P-VOL and S-VOL are not reversed.
