10 Troubleshooting
This chapter provides Continuous Access Journal troubleshooting information.
General troubleshooting
When an error occurs in a Continuous Access Journal pair operation with Remote Web Console,
an error message displays with a four-digit error code and description. An SVP error code may
also be included. See the HP XP P9000 Remote Web Console Messages for details on error codes.
You can download Remote Web Console dump files using the FD Dump tool. If you are unable to
resolve an error, use the tool to copy the dump files to a file, and then contact the HP Technical
Support for assistance.
The following describes general troubleshooting problems and solutions for Continuous Access
Journal.
Corrective actionError
Make sure that the problem is not being caused by the computer or Ethernet
hardware or software, and restart the computer. Restarting the Remote
Web Console computer does not affect Cnt Ac-J operations in progress.
Remote Web Console hangs, or Cnt Ac-J operations
do not function properly.
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 105).
The status of a logical path is not normal.
Check the pair status in the Detailed Information dialog box, and see
“Troubleshooting by suspension type ” (page 107) for suspend types and
corrective action.
The pair status is suspended.
