8-22 Chapter 8 Performing Pair Operations
Hitachi Universal Replicator for IBM /OS User’s Guide
• In the Preview list, select all but one pair in the same mirror, right click
the selected pairs, and then select Delete.
• Suspend Mode: Allows you to specify how to deal with update data that
has not been copied to the secondary data volume. The default is Flush:
– Flush: When you split the pair, update data will be copied to the
secondary data volume.
When the secondary storage system receives a request for splitting a
pair, all the journal data (i.e., update data) that the pair retains will be
written to the secondary data volume. After that, the status of the pair
will change from Suspending to Suspend if the pair does not retain
any journal data for a certain period of time.
– Purge: When you split the pair, update data will not be copied to the
secondary data volume. If you restore the pair later, the update data
will be copied to the secondary data volume.
• Set: Applies the settings to the Preview list in the Pair Operation window
(
Figure 4-2).
• Cancel: Discards the settings.
