Using the YKQUERY command to obtain the copy pair status for each copy pair
You can use the YKQUERY or YKEWAIT command or the Copy Group Pair Status panel to obtain
the copy pair status for each copy pair.
The copy pair status for each copy pair is determined by the combination of the copy pair statuses
of the P-VOL and S-VOL. When the status can be obtained from only the P-VOL or S-VOL, the
obtained status will be the copy pair status of the copy pair.
For Continuous Access Synchronous Z, TrueCopy Asynchronous for Mainframe, or Continuous
Access Journal Z, if the command is executed for a remote storage system when a command device
has not been defined, the copy pair status for the remote storage system is not displayed.
CAUTION:
If you attempt to obtain copy pair information from an inaccessible site (due to a line
failure, for example), an error will occur even if information from available sites has been obtained.
You can prevent the error in such cases by executing the YKQUERY command with the TO parameter
specified. This parameter allows you to specify the site (P-VOL or S-VOL when they were defined)
from which information can be obtained. For details about the information that can be obtained
by the YKQUERY command with the TO parameter, in the HP XP7 for Business Continuity Manager
Reference Guide, see the explanation of the REXX variable that is updated by the YKQUERY
command with the TO parameter.
NOTE:
The YKQUERY and YKEWAIT commands determine the copy pair status based on the
collected information, even if the defined copy types or combinations of copy pairs differ from
actual copy types or combinations of copy pairs.
The following common legend is used for
