HP StorageWorks XP Remote Web Console Software - Manual (Page 190)

NOTE:
◦ You can select only one secondary data volume even when two or more primary data
volumes are selected in the Pair Operation window. Universal Replicator for Mainframe
automatically specifies the other secondary data volumes. For detailed information, see
the explanation about the Select Other S-VOL(s) option later in this section.
◦ If you selected more than one primary data volume, select the secondary data volume
for the primary data volume being displayed. The secondary data volumes for the rest
of the primary data volumes are automatically assigned according to the volume number.
For example, if you select three primary data volumes and select 01 as the S-VOL for the
first primary data volume, the secondary data volumes for the two other primary data
volumes will be 02 and 03.
◦ When creating more than one pair at a time, make sure that the S-VOLs to be assigned
automatically are available. If an S-VOL is not available, you will have to select the S-VOL
individually.
•
Select Other S-VOL(s): Specify how Universal Replicator for Mainframe automatically will
assign secondary data volumes if two or more primary data volumes are selected in the Pair
Operation window.
◦ Increment: Universal Replicator for Mainframe increments the volume numbers of the
resulting secondary data volumes one by one. For example, if the volume numbers of the
three primary data volumes are 01, 02, and 03, the volume numbers of the resulting
secondary data volumes will be 11, 12, and 13 if you select the volume number 11 with
the S-VOL drop-down list.
◦ Input Next: Universal Replicator for Mainframe users can specify a volume number for
each primary data volume. For example, if two primary data volumes are selected, the
Universal Replicator for Mainframe user must select Input Next, specify the secondary
data volume for the first primary data volume with S-VOL, and then click Set. Next, the
user must specify the secondary data volume for the second primary data volume with
S-VOL, and then click Set.
◦ Relative to P-VOL: Universal Replicator for Mainframe calculates the difference between
the volume numbers of two adjacent primary data volumes, and then determines the
volume numbers of the secondary data volumes.
For example, if the volume numbers of the three primary data volumes are 01, 05, and
06, the volume numbers of the resulting secondary data volumes will be 02, 06, and 07
if you select the volume number 02 with the S-VOL drop-down list.
NOTE: If you select and right-click more than one volume in the Preview list and then select
Modify, the Add Pair window appears and the Select Other S-VOL(s) drop-down list displays
No Change. To change the setting with this drop-down list, select another item from the
drop-down list.
•
Mirror: Assigns a master journal group to the primary data volume, assigns a restore journal
group to the secondary data volume, and also assigns a mirror ID to the volume pair.
◦ M-JNL: Assigns a master journal group to the primary data volume.
NOTE: M-JNL does not display journal group numbers used by XP Continuous Access.
◦ Mirror ID: Assigns a mirror ID to the volume pair.
◦ R-JNL: Assigns a restore journal group to the secondary data volume.
NOTE: M-JNL and R-JNL do not display journal group numbers used by XP Continuous
Access Journal.
