In the following situations, Business Continuity Manager issues an error message and the command
terminates abnormally.
• One or more copy pairs in the copy group cannot transition to the status specified by the
GOTO parameter, due to failure.
• All volumes in the copy group do not transition to the specified copy pair status within the
time specified by the TIMEOUT parameter.
The YKEWAIT command with the DEVN parameter specified can be used to monitor status transitions
for a specific copy pair in a copy group.
Status Monitoring by Volume
An error will occur when copy pair information cannot be obtained from the storage system of the
P-VOL or S-VOL, due to a failure. However, the YKEWAIT command can be used with the TO
parameter specified, so that status monitoring is performed only for either the P-VOL or S-VOL, and
errors are suppressed.
The YKEWAIT command can also be used with the DEVN parameter specified in order to monitor
status changes for a specific volume in a copy group.
