HP P9000 Business Continuity Manager Reference Guide (T5253-96058, September 2011)

The site names are for cases when the copy direction of copy pair configuration and the copy
direction which is actually recognized on the storage system are the same. For the opposite copy
direction, replace the primary site and secondary site with the secondary site and primary site
respectively. However, do not dissolve copy pairs during a planned outage.
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.
