•
S-VOL Write: Specifies whether hosts can issue read and write I/Os to the secondary data
volume after the mirror is split.
◦ Enable: Hosts can issue read and write I/Os to the secondary data volume after you split
the mirror.
◦ Disable: Hosts cannot issue read and write I/Os to the secondary data volume after you
split the mirror. This is the default.
This parameter takes effect only when the selected volume is a master journal group.
•
Range: Split range. This is always set to Group and cannot be changed.
•
Suspend Mode: Specify how to handle update data that is not applied to the secondary data
volume.
◦ Flush: Update data is applied to the secondary data volume when you split the mirror.
This is the default.
When the secondary array receives a request for splitting a mirror, all journal data (that
is, update data) that the mirror retains is written to the secondary data volume. After that,
the mirror's status changes from Suspending to PSUS if the mirror does not retain any
journal data for a certain period of time.
◦ Purge: Update data is not applied to the secondary data volume when you split the mirror.
If you restore the mirror, update data is applied to the secondary data volume.
Restoring mirrors (Pairresync: resuming copy operations)
A mirror is a combination of a master journal group and a restore journal group. If you split a
mirror, copying data from the master journal group to the restore journal group is suspended. To
restart data copying, you must restore the mirror.
If you are logged onto an XP10000, you can perform this operation only on journal groups that
have a number below 10.
To restore a mirror, only primary array administrators can perform the following procedure:
1. Ensure that XP Command View Advanced Edition Software or XP Remote Web Console is in
Modify mode. For more information, see the HP StorageWorks XP Command View user guide
for XP Disk Arrays or the HP StorageWorks XP Remote Web Console user guide for
XP12000/XP10000/SVS200.
2. Display the Journal Operation pane (see Displaying the Journal Operation pane ).
