2. If multiple pairs are created at one time, use the Select Other S-VOL(s) list to specify
S-VOLs.
If you selected multiple volumes as P-VOLs, you can instruct the system to automatically
assign S-VOLs for the remainder of P-VOLs. Do this from the Select Other S-VOL(s) list, as
follows:
- Select Increment to cause Continuous Access Journal to add the secondary system LUN
incrementally. Your S-VOL LUN numbers must be numbered incrementally. 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.
- Select Input Next to specify S-VOL LUN one at a time for each P-VOL. For example, if
after setting the S-VOL LUN for the current P-VOL you click the Set, then you would reopen
the dialog box to set the next S-VOL, and so on.
- Select Relative to P-VOL to cause Continuous Access Journal to add S-VOL LUN closest
in number to the P-VOL's LUN. For example, if the LUN numbers of the three P-VOLs are
001, 005, and 006; and you select LUN 002 for the first S-VOL, LUN numbers 006 and
007 will be assigned by the system as the next two S-VOLs.
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.
6. In the Mirror box, proceed as follows.
1. Select the master journal from the M-JNL list. In the M-JNL list, the number of existed
journal other than restore journal is displayed.
2. Select a mirror ID (0 to 3) from the Mirror ID list.
3. Select a restore journal from the R-JNL list. In the R-JNL list, the all number of journal
between 000 and 0FF are displayed.
NOTE:
Continuous Access Journal Z.
7. From the CT Group list, specify the consistency group number. If possible, assign the consistency
group number matching the Continuous Access Journal journal number (best practice).
8. In the Initial Copy list, select one of the following:
Entire, to create the Continuous Access Journal pair relationship and copy the data from
primary to secondary volumes immediately.
None, to create the Continuous Access Journal pair relationship but copy no data from
primary to secondary volumes. You must be insure that data in the P-VOL and S-VOL are
identical when selecting None.
Delta, to create the Continuous Access Journal pair for a delta resync. No initial copy
operation starts after the volume pair is created. The status of the volume pair changes
to HOLD or HOLDING.
9. In the Priority list, specify the scheduling order for the initial copy operation. The default value
is 32, and 1 to 256 can be specified.
For performing more initial copy operations than the setting value of the Maximum Initial Copy
Activities set on the System Option dialog box, the scheduling order (Priority) can be set for
the initial copy operations to be performed.
The Priority is determined within the range of the number of initial copy operations performed
at the same time. Therefore, until the first initial copy operations complying with the order of
the Priority are completed, the additionally specified initial copy operations are not started.
If a time-out error occurs during the Add Pair operation, the copy operation may not be
executed correctly in the order specified in the Priority field. A time-out error may be caused
