Data Retention Utility
Data Retention Utility can set four different kinds of access attributes on the volumes: Read/Write,
Read Only, Protect, and S-VOL Disable. XP Snapshot cannot create a pair by specifying a volume
whose access attribute is S-VOL Disable as the S-VOL. In addition, if the S-VOL Disable attribute
is set on the P-VOL of the XP Snapshot pair, you cannot restore the pair.
By using Data Retention Utility, you can set the Read/Write, Read Only, Protect, or S-VOL Disable
attribute on the volumes that are already used by the XP Snapshot pairs. However, when the pair
is in the following status, you cannot set the S-VOL Disable attribute on the pair volumes:
•
COPY*
•
SMPL(PD)*
•
COPY(RS)*
•
COPY(RS-R)
•
PSUE*
*: You can set S-VOL Disable on the P-VOL even if the pair status is COPY, SMPL(PD), COPY(RS),
or PSUE.
For detailed information about setting the access attribute, see the HP XP24000/XP20000 Data
Retention Utility User Guide.
Auto LUN
Regardless of the status of the migration plans of Auto LUN, you cannot perform any XP Snapshot
operations on a volume that is used by the migration plan. To use an XP Snapshot P-VOL as the
source volume for the migration plan, you need to create the XP Snapshot pair first, and then create
the migration plan.
When the XP Snapshot P-VOL and the source volume for the migration plan are shared, you can
execute the migration plan only when the XP Snapshot pair is in PAIR status. Deleting and canceling
the migration plan are always allowed. These operations are not affected by the XP Snapshot pair
status.
For information on using XP Auto LUN, contact HP technical support (see

volume to create an XP Snapshot pair. Also, if you use a volume of an XP Snapshot pair to
