HP XP P9000 for Business Continuity Manager Software Reference Guide

When dissolving copy pairs in a CG container specified by EXCTG ID, if all copy pairs are dissolved
from a journal group, that journal group will be deleted from the EXCTG. In addition, if all journal
groups are deleted from the EXCTG, the EXCTG data will be deleted.
Parameters
STEM(stem-name-1) ~ <REXX prefix of 64 or fewer characters>
Specify the prefix of the name of the copy group structure that stores information about the copy
group for which you want to dissolve the copy pairs. Specify the same character string as the one
specified in the STEM parameter of the YKLOAD command that loaded the corresponding copy
group. You must also include a trailing period character.
MSG(stem-name-2) ~ <REXX prefix of 64 or fewer characters>
Specify an optional prefix for the name of the message structure used to store the messages to be
generated by this command. You must also include a trailing period character.
The message structure is initialized when the CLI command with the same name as the MSG
parameter is specified.
DEVN(p-vol-device-number,s-vol-device-number) ~ <4-digit hexadecimal number, 4-digit
hexadecimal number>
Specify the device number of the copy pair (P-VOL and S-VOL) to operate.
NOTE:
• Do not dissolve copy pairs during a planned outage.
• In 4x4x4 Delta Resync configurations, when all copy pairs in EXCTG whose copy direction
is from the primary site to the remote site are dissolved, the journal groups whose copy direction
is from the local site to the remote site are also dissolved from EXCTG registration.
For example, if a Delta Resync is executed and then the YKRECVER command is executed
when EXCTG is in the HOLD status and the copy direction is from the primary site to the remote
site, the journal groups whose status is DUPLEX and copy direction is from the local site to the
remote site are dissolved from EXCTG registration. As a result, the YKZ296E message is output
if the YKQUERY command is executed to obtain the status of Universal Replicator copy pairs
whose copy direction is from the local site to the remote site. In this case, perform either of
the following operations to register journal groups in EXCTG for the storage system:
◦ Execute the YKMAKE HOLD command for Universal Replicator copy pairs whose copy
direction is from the primary site to the remote site.
◦ Execute the YKMAKE command with a SELECT(COND) specified for Universal Replicator
copy pairs whose copy direction is from the local site to the remote site.
Return Codes
Table 125 (page 236) lists the return codes to be returned when the YKRECVER command terminates.

not been included properly.
