8-26 Chapter 8 Performing Pair Operations
Hitachi Universal Replicator for IBM /OS User’s Guide
Releasing a Pair of Data Volumes
The Delete Pair window (Figure 8-8) allows you to release a pair of data
volumes.
When one journal group uses two mirror IDs, the result of the operation differs
as follows according to the status of the mirror of specified URz pair.
• When you specify a mirror of the URz pair in Hold or Hlde status, only the
URz pair of the specified mirror will be deleted.
• When you specify a mirror of the URz pair that is not in Hold or Hlde
status, URz pairs of both mirrors (including the mirror which you do not
specified) will be deleted.
To release one or more pair(s), follow the procedure below. Not only the
primary storage system administrator but also the secondary storage system
administrator can perform this operation:
1. Ensure that the Storage Navigator main window is in Modify mode.
