Split the Universal Replicator for Mainframe pairs by using the SuspendPair tag. When using
the SuspendPair tag, you can use the information of LDKC, CU, LDEV, MirrorID, and DKCSN
from the output of Step 2 to write the SuspendPair parameters.

Example

#!Version 05_02_01, CLI_RemoteCopyJournalMF, PairOperation,;
[SuspendPair]
#LDKC, CU, LDEV, MirrorID, VolType, LDKC(Pair), DKCSN, Range, S-VOLWrite, SuspendMode
00, 00, 00, 00, P-VOL, 00, 2222, Group, Disable, Flush,;

When splitting all the pairs in a mirror, by specifying Range for Group, only specify one
Universal Replicator for Mainframe pair in the mirror.

4.

Resynchronize the Universal Replicator for Mainframe pairs by using ResumePair tag. When
using the ResumePair tag, you can use the information for LDKC, CU, LDEV, MirrorID, M-JNL,
and DKCSN from the output of Step 2 to write the ResumePair parameters. In addition, you
can use the information of LDKC(S) to write the LDKC(Pair) information.

Example

#!Version 05_02_01, CLI_RemoteCopyJournalMF, PairOperation,;
[ResumePair]
#LDKC, CU, LDEV, MirrorID, M-JNL, LDKC(Pair), DKCSN, ResyncMode, Range, Priority, ErrorLevel, CFW
00, 00, 00, 00, 00, 00, 22222, 5, Normal, Group, 32, Group, Only_P-VOL,;

When resynchronizing all the pairs in a mirror, by specifying Range for Group, only specify
one Universal Replicator for Mainframe pair in the mirror.

The information displayed by the Pair tag can be used to write the parameters of SuspendPair or
ResumePair tags. Also, this information is useful when you release a pair and recreate the pair by
using the same volumes. Reduce time and avoid mistakes by copying this pair information and
saving it for later use.

Splitting Pairs (SuspendPair Tag)

When the pair status is Pending or Duplex, you can split the pair by using SuspendPair tag. Import
the spreadsheet to the primary or secondary site and then perform the CLI by using the spreadsheet
with the SuspendPair tag from either the primary or secondary site.

If volumes other than Universal Replicator for Mainframe data volumes are specified in the
spreadsheet with a SuspendPair tag, an error occurs and pair operations defined by other tags in
the spreadsheet may not execute. When an error occurs, use the Pair tag or the Pair Operation
window to check the volume status. If pair operations are not executed because of the error,
recreate the spreadsheet and execute the operation again.

The table below shows the detailed settings for the SuspendPair tag.
