HP StorageWorks XP Remote Web Console Software - Manual (Page 157)

To continue processing, do either of the following:
◦ Ensure that the Range column displays Volume for all pairs in the same mirror.
◦ In the Preview list, select all but one pair in the same mirror, right click the selected pairs,
and then select Delete.
•
Delete Mode: Allows you to specify whether to release the pair(s) forcibly. When the status of
the pair(s) to be released is Simplex, Suspending, or Deleting, the default setting is Force.
Otherwise, the default setting is Normal:
◦ Force: The pair(s) will forcibly be released even if the primary storage system is unable
to communicate with the secondary storage system. This option may be used to free a
host waiting for device-end from a primary storage system that cannot communicate with
its the secondary storage system, thus allowing host operations to continue.
If you specify Force when the pair status is other than Simplex, Suspending, or
Deleting,Range will be set to Group.
NOTE: When you delete a pair forcibly by specifying Volume for Range, other pairs
in the same journal group as the specified pair will be suspended by failure.
◦ Normal: The pair(s) will be released only if the primary storage system is able to change
the pair status of the primary and secondary data volumes to Simplex.
•
Set: Applies the settings to the Preview list in the Pair Operation window ( “Pair Operation
Window” (page 136) ).
•
Cancel: Discards the settings.
Creating a Point-in-Time Copy of Data Volumes
URz enables you to make Point-in-Time (PiT) duplicates of groups of volumes. The term "Point-in-Time
(PiT)" refers to an act of obtaining a copy of data immediately when you want to obtain it. The
URz can be used to create a PiT copy of data volumes belonging to a journal group.
To produce a PiT duplicate of data volumes belonging to a journal group:
1. Stop all write I/Os from hosts to primary data volumes in the journal group. Stop all host
updates to all URz primary data volumes in the group.
2. After all write I/Os to primary data volume have stopped, split the mirror (that is, a pair of
the master and restore journal group. When splitting it, use the Suspend Pair window and
then specify Group for Range and specify Flush for Suspend Mode.
3. When the status of all data volume pairs in the journal group has changed to Suspend, the
duplicate set of volumes is complete. If desired, you can restart your business application at
the primary site to resume business activities.
