10 Troubleshooting
This chapter provides troubleshooting information.
General troubleshooting
General troubleshooting information for Continuous Access Journal follows.
Table 15 General troubleshooting
Corrective actionError
Make sure that the problem is not being caused by the computer or
Ethernet hardware or software, and restart the computer. Restarting
Remote Web Console hangs, or Cnt Ac-J
operations do not function properly.
the Remote Web Console computer does not affect Cnt Ac-J
operations in progress.
Make sure that all Cnt Ac-J requirements and restrictions are met.
Make sure that the primary and secondary systems and remote copy
connections are powered on, and that NVS and cache are fully
operational.
Check all the entered values and parameters to make sure that you
entered the correct information on the Remote Web Console computer
(for example, secondary system S/N, path parameters, P-VOL and
S-VOL IDs).
If you are using Performance Monitor, refrain from using it.
Please call HP Technical Support for assistance.An initiator channel-enable LED indicator (on the
control window) is off or flashing.
Make sure that the correct CU image is selected.Status of pairs and/or logical paths is not
displayed correctly.
Check whether you selected correct items or options in Cnt Ac-J
windows, such as the DKC Operation window, the Pair Operation
window, and the Display Filter dialog box.
Remove the error cause, and then retry the Cnt Ac-J operation.A Cnt Ac-J error message appears on the Remote
Web Console computer.
Check the path status in the DKC Status dialog box, and see
“Troubleshooting logical paths ” (page 104).
The status of a logical path is not normal.
Check the pair status in the Detailed Information dialog box, and
see “Troubleshooting suspended pairs ” (page 106) for suspend types
and corrective action.
The pair status is suspended.
If the timeout error was caused by a hardware failure, a SIM is
generated. See “Service information messages (SIMs) ” (page 119).
The pair create or pair resync operation resulted
in a timeout error.
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 pair(s) 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 communication error occurs between the Remote Web Console
computer and the SVP, see HP P9000 Remote Web Console User
Guide for instructions.
Because the time setting of SVP is changed, the monitoring data
might not be updated. Set Monitoring Switch to Disable, and set
Although Monitoring Switch is set to Enable, the
monitoring data is not updated.
Monitoring Switch to Enable again. For further information on
