Combining XP Snapshot with Auto LUN XP
Regardless of the status of Auto LUN XP's migration plans (Auto LUN XP pairs), you cannot perform
any Snapshot operations on the volume the migration plan uses. To use a XP Snapshot P-VOL as the
migration plan's source volume, you must create the XP Snapshot pair first, and then create the
migration plan.
When the XP Snapshot P-VOL and migration plan's source volume 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 more information about the status of migration plans and Auto LUN XP operations, see the HP
StorageWorks Auto LUN XP user guide for the XP12000/XP10000.
Combining XP Snapshot with LUN Security XP Extension
LUN Security XP Extension can set four 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
XP Snapshot pair's P-VOL, you cannot restore the pair.
By using LUN Security XP Extension, you can set the Read/Write, Read Only, Protect, or S-VOL Disable
attribute on volumes that XP Snapshot pairs already use. However, when the pair is in the following
statuses, you cannot set the S-VOL Disable attribute on the pair volumes:
• COPY
• SMPL(PD)
• COPY(RS)
• COPY(RS-R)
• PSUE
NOTE:
You can set S-VOL Disable on the P-VOL even if the pair status is COPY, SMPL(PD), COPY(RS), or
PSUE.
For more information about setting the access attribute, see the HP StorageWorks LUN Security XP
Extension user guide.
