Corrective actionError
The pair create or pair resync operation resulted in
a timeout error.
• If the timeout error was caused by a hardware failure, a SIM is
generated. See “Service information messages (SIMs) ” (page 120). If
necessary, call HP Technical Support, and retry Cnt Ac-J operations
after the problem is solved.
• If no SIM was generated, wait for a while (5 or 6 minutes), then check
the pair status of the pairs being created or resumed. If the pair status
changed correctly, the failed operation completed after the timeout
message was issued. If the pair status did not change as expected,
heavy workload might have prevented the Cnt Ac-J operation from
being completed. In this case, retry the Cnt Ac-J operation when the
system has a lighter workload.
• If a time-out error occurs during the paircreate operation, the copy
operation might not have been executed correctly in the order specified
in the Priority field. A time-out error may be caused by the CU
configuration or a remote copy path error. Review the error, release
the pair with the error, and then retry the paircreate operation.

journal volumes that belong to the journal, then delete the journal group
again.

message.
• The Preview list contains two or more pairs belonging to the same
mirror.
• Mirror is defined in the Range column for at least one of the above
pairs.
To continue processing, do either of the following:
• Ensure that the Range column displays LU for all pairs in the same
mirror.
• In the Preview list, delete all but one pair in the same mirror.
The error code appears in the right-most column of the Preview list. To
view detailed information about the error, right click the error code and
select Error Detail.
