DescriptionItem
Specify whether to start the initial copy operation after the volume pair is created. The default
is Entire.
Initial Copy
• 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.
Specify priority (scheduling order) of the initial copy operations (1 256). The default setting is
32.
Priority
If the time out error occurs during the Paircreate 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 Paircreate operation.
For the details of the scheduling order of the initial copy for which the Priority is set, see“Priority
set for initial copy operations and scheduling order” (page 26).
Specify the range used for splitting a pair when a failure occurs. The default is Mirror.Error Level
• Mirror: If a failure occurs with a pair, all pairs in the mirror where the pair belongs are
split.
• LU: If a failure occurs with a pair, only the pair are split.
Displays information about the master journal.M-JNL Information
• Current Mirror(s): Indicates the number of mirrors registered in the master journal.
• Total Mirror(s): Indicates the sum of the following:
(1) The number of mirrors registered in the master journal.
(2) The number of mirrors to be added by the Paircreate dialog box.
(3) The number of mirrors for volumes in the Preview list in the Pair Operation window.
