Legend:
Yes: Related.
N/A: Not applicable.
NOTE:
If the required configuration for the function in use is not set, the status might not be
acquired correctly in situations such as:
•
While copying in the reverse direction, if Business Continuity Manager cannot issue any I/Os
to an S-VOL, the SWAPPING status will not be acquired correctly. If this occurs, the pair will
be put in the SUSPOP status instead.
•
While performing a Delta Resync on copy pairs, if Business Continuity Manager cannot issue
any I/Os to a P-VOL, the HOLDER, HOLDTRNS, and NODELTA status will not be acquired
correctly. If this occurs, the pair will be put in the HOLD status instead.
Using the YKQRYDEV command to obtain the copy pair status of specified volumes
You can use the YKQRYDEV command or the Volume Query Information panel to obtain the copy
pair status of specified volumes.
When the Volume Query Information panel is used to display the copy pair status, the YKQRYDEV
command is executed for the P-VOL and S-VOL of the specified copy pair, and the copy pair status
of each volume is displayed. However, if the command is executed for volumes in a remote storage
system when a command device has not been defined, the copy pair status of the volumes in the
remote storage system is not displayed.

of Continuous Access Synchronous Z, TrueCopy Asynchronous for Mainframe, Continuous Access
Journal Z, and Business Copy Z volumes that can be obtained by using the YKQRYDEV command.
