Description
Specify how Cnt Ac-J Z automatically assigns S-VOLs if two or more P-VOLs are selected in the
Pair Operation window.
Increment: Cnt Ac-J Z increments volume numbers of the resulting S-VOLs one by one. For
example, if you create 3 pairs and specify 1 1 on the LDEV of P-VOL, the LDEVs on the
secondary system are incremented at 1 1, 12, and 13.
Input Next: You can specify a volume number for each P-VOL. For example, if two P-VOLs
are selected, the 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 Z calculates the difference between volume numbers of two
adjacent P-VOLs, and then determines volume numbers of S-VOLs.
For example, if the volume numbers of the three P-VOLs are 01, 05, and 06, the volume
numbers of the resulting S-VOLs will be 02, 06, and 07 if you select the volume number
02 with the S-VOL list.
If you select and right click more than one volume in the Preview list and select Modify, the
Add Pair dialog box 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.
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.
Mirror ID: Assigns a mirror ID to the volume pair.
R-JNL: Assigns a restore journal to the S-VOL.
M-JNL and R-JNL does not display journal numbers used by Continuous Access Journal.
Select the serial number (the LDKC number) and the controller ID (model name that indicates
the model) of the secondary storage system. This option also allows you to specify the path
type (i.e., channel type).
The secondary storage system must be the same for all pairs being created during one operation.
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.
The user must 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.
Specify priority (scheduling order) of the initial copy operations (1 256). The default setting is
32.
If the time out error occurs during the Add Pair operation, the copy operation may not be
executed correctly in the order that you have set with the Priority parameter. The time out error
may be caused by the CU configuration or a remote copy path error. Review the error, release
the pair with the error, and then retry the Add Pair operation.
For the details of the scheduling order of the initial copy for which the Priority is set, see
set for initial copy operations and scheduling order" (page
Specify the range used for splitting a pair when a failure occurs. The default is Mirror.
Mirror: If a failure occurs with a pair, all pairs in the mirror where the pair belongs are
split.
Volume: If a failure occurs with a pair, only the pair is split.
