Item Description
Select a S-VOL. When specifying a S-VOL, you must use the three lists to select a port, a GID,
and an LUN of the S-VOL. The GID is a group number for a host group.
You can select only one S-VOL even when two or more primary data volumes are selected in
the Pair Operation window. Cnt Ac-J automatically specifies the other S-VOLs. For detailed
information, see the explanation about the Select Other S-VOL(s) option later.
If you selected more than one primary data volume, select the S-VOL for the primary data
volume being displayed. The S-VOLs for the rest of the 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 S-VOLs for the two other
primary data volumes is LUN02 and LUN03.
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, select the S-VOL individually.
You can specify the port number with two characters. For instance, 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) For multiple pairs, sets S-VOLs for other P-VOLs.
Specify how Cnt Ac-J automatically assigns S-VOLs if two or more P-VOLs are selected in the
Pair Operation window.
Increment: Cnt Ac-J increments LUNs of the resulting S-VOLs one by one. For example, if
you create 3 pairs and specify 01 1 on the LUN of P-VOL, the LUNs on the secondary system
are incremented at 01 1, 012, and 013.
Input Next: Specify a LUN for each P-VOL. For example, if two P-VOLs are selected, select
Input Next, specify the S-VOL for the first P-VOL with S-VOL, and then click Set. Next, specify
the S-VOL for the second P-VOL with S-VOL, and then click Set.
Relative to P VOL: Cnt Ac-J calculates the difference between LUNs of two adjacent P-VOLs,
and then determines LUNs of S-VOLs.
For example, if the LUNs of the three P-VOLs are 001, 005, and 006, the LUNs of the
resulting S-VOLs will be 002, 006, and 007 if you select the LUN 002 with the S VOL list.
If you select and right click more than one volume in the Preview list and then select Modify,
the Paircreate dialog box opens and the Select Other S VOL(s) list indicates No Change.
If you want to change the setting with this list, select another option from the list.
Mirror Assigns a master journal to the P-VOL, assigns a restore journal to the S-VOL, and also assigns
a mirror ID to the volume pair.
M-JNL: Assigns a master journal to the P-VOL.
M-JNL does not show journal numbers used by Continuous Access Journal Z.
Mirror ID: Assigns a mirror ID to the volume pair.
R-JNL: Assigns a restore journal to the S-VOL.
R-JNL does not show journal numbers used by Continuous Access Journal Z.
CT Group Specify a consistency group. This option cannot be changed after a pair has been created.
DKC Select the serial number with the number of LDKC and the controller ID with the model name
of the secondary storage system. This option also allows you to specify the path type (that is,
channel type). The secondary storage system must be the same for all pairs being created
during one operation.
Initial Copy Specify whether to start the initial copy operation after the volume pair is created. The default
is Entire.
Entire: The initial copy operation starts after the volume pair is created. When the initial
copy operation executes, all data on the P-VOL is copied to the S-VOL.
None: The initial copy operation does not start after the volume pair is created. The primary
storage system starts copying of update data as needed. Ensure that the P-VOL and S-VOL
are already identical when using None.
Delta: No initial copy operation starts after the volume pair is created. The status of the
volume pair changes to HOLD or HOLDING, which means that the pair is for delta resync
operation.
