HP XP Continuous Access Software - Manual (Page 138)

NOTE: You can select only one secondary data volume even when two or more primary
data volumes are selected in the Pair Operation pane. XP Continuous Access Journal
automatically specifies the other secondary data volumes. For more information, see the
explanation for the Select Other S-VOL(s) option.
NOTE: If you selected more than one primary data volume, select the secondary data volume
for the primary data volume being displayed. Secondary data volumes for the remaining
primary data volumes are automatically assigned according to the LUN. For example, if you
select three primary data volumes and select LUN01 as the S-VOL for the first primary data
volume, the secondary data volumes for the two other primary data volumes are LUN02 and
LUN03.
NOTE: When creating more than one pair at a time, ensure that the S-VOLs to be
automatically assigned are available. If an S-VOL is not available, you must select S-VOLs
individually.
NOTE: You can specify the port number with two characters. For example, you can abbreviate
CL1-A to 1A. You can also enter the port number in both lowercase and uppercase characters.

Select Other S-VOL(s): Specifies how XP Continuous Access Journal automatically assigns
secondary data volumes if you select two or more primary data volumes in the Pair Operation
pane.
◦ Increment: XP Continuous Access Journal increments the resulting secondary data volumes'
LUNs by one. For example, if the three primary data volumes' LUNs are 001, 002, and
003, the resulting secondary data volumes's LUNs are 011, 012, and 013 if you select
LUN 011 from the S-VOL list.
◦ Input Next: You can specify a LUN for each primary data volume. For example, if you
select two primary data volumes, you must select Input Next, specify the secondary data
volume for the first primary data volume with S-VOL, and click Set. Next, you must specify
the secondary data volume for the second primary data volume with S-VOL, and click
Set.
◦ Relative to P-VOL: XP Continuous Access Journal calculates the difference between LUNs
of two adjacent primary data volumes, and then determines the secondary data volumes'
LUNs. For example, if the three primary data volumes' LUNs are 001, 005, and 006,
the resulting secondary data volumes' LUNs are 002, 006, and 007 if you select LUN
002 from the S-VOL list.
NOTE: If you select and right-click more than one volume in the Preset list and select
Modify, the Paircreate pane appears, and the Select Other S-VOL(s) list displays No
Change. To change the setting with this list, select another item from the list.
•
Mirror ID: Assigns a master journal group to the primary data volume, assigns a restore journal
group to the secondary data volume, and 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 Hitachi Universal
Replicator for z/OS.
NOTE: M-JNL displays only journal groups containing journal volumes belonging to
the CLPR where the selected volumes belong.
◦ Mirror ID: Assigns a mirror ID to the volume pair.
◦ R-JNL: Assigns a restore journal group to the secondary data volume.
