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 Z to add the secondary system
LDEV incrementally. Your S-VOL LDEV numbers must be numbered incrementally. 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.
- Select Input Next to specify S-VOL LDEV numbers one at a time for each P-VOL. For
example, if after setting the S-VOL LDEV 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 Z to add S-VOL LDEV
numbers closest in number to the P-VOL's LDEV numbers. For example, if the LDEV numbers
of the three P-VOLs are 001, 005, and 006; and you select LDEV numbers 02 for the
first S-VOL, LDEV numbers 06 and 07 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 unused or
existed master journal on the primary storage system 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.
The M-JNL list does not display journal numbers used by Continuous Access Journal Z.
7. In the DKC list, select the secondary system. In the DKC list, display the serial number, the
LDKC number, the controller ID, and the model name about the secondary storage system.
The secondary system must be the same for all pairs being created during one operation.
8. In the Initial Copy list, select one of the following:
Entire, to create the Continuous Access Journal Z pair relationship and copy the data
from primary to secondary volumes immediately.
None, to create the Continuous Access Journal Z 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 Z 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
