What to do if the status of pairs and/or logical paths is not displayed correctly in HP XP P9500?
Make sure that the correct CU image is selected. 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.
What happens to HP XP P9500 Software Cnt Ac-J Z pairs during a planned power outage?
During a planned power outage to the primary system, the Cnt Ac-J Z pairs are temporarily suspended. No recovery procedure is required. The primary system automatically removes the suspension condition when the system is powered on.
What to do if HP XP P9500 shows 'Communication error'?
A timeout error has occurred in the path between the primary and secondary systems. Delete the failed path and retry.
How to resume HP XP P9500 pair suspended by R-VOL?
If the user suspended the HP Software pair from the MCU or RCU using the R-VOL for Suspend Kind option, resynchronize the pair from the MCU (Resume Pair).
What to do if the HP XP P9500 Remote Web Console hangs?
If the HP Software Remote Web Console hangs, ensure the issue isn't with your computer, Ethernet hardware, or software. Restart your computer, which won't impact ongoing Cnt Ac-J operations. Verify all Cnt Ac-J requirements are met. Confirm that the primary and secondary systems, along with remote copy connections, are powered on and fully operational, including NVS and cache. Double-check all entered values and parameters in the Remote Web Console for accuracy, such as the secondary system S/N and path parameters. Avoid using Performance Monitor during these operations.
How to resolve HP XP P9500 Software Pair-Port Type Mismatch error?
If you get a 'Pair-Port Type Mismatch' error in HP Software, it means the specified port in the secondary system isn't configured as an RCU Target port. Make sure that the specified port in the secondary system is configured as an RCU target port.
What causes the error: primary storage system could not find valid control information in HP XP P9500?
If the primary storage system could not find valid control information in its nonvolatile memory during the IMPL procedure in HP Software, and this error occurs only if the primary storage system is without power for more than 48 hours (power failure and fully discharged batteries), restore the pair (pairresync) from the primary storage system. The primary storage system performs an initial copy operation in response to the pairresync request, so that the entire P-VOL is copied to the S-VOL.
What to do if I see a fence message displayed on the console of my HP Disk array system?
If a fence message appears on the console, first check for a failed storage path. If a failed path is found, toggle the RESTART switch and retry the operation. Should the fence message reappear, it is recommended to contact the support center for assistance.
What does 'Pair-Port Number Mismatch' mean in HP XP P9500 Software?
The 'Pair-Port Number Mismatch' error in HP Software indicates that the specified port in the secondary system is physically disconnected from the primary system. Make sure of the following: * That you specified the correct secondary system port. Correct the port number if necessary. * The primary and the secondary systems ports are connected with cables. If the systems are not connected by cables, connect them and retry the operation. * That the topology settings of ports on the primary and secondary systems are correct.
What to do if HP Software shows 'Serial Number Mismatch'?
If the HP Software shows a 'Serial Number Mismatch', it means the serial number (S/N) of the secondary system does not match the specified serial number. Ensure that you entered the correct secondary system S/N and path parameters (for example, primary and secondary system port, and controller ID). After that, delete the failed path. You may need to change the minimum paths setting or delete the secondary system in order to delete the path. After deletion finishes, add the path and the secondary system back. Make sure that you entered the correct controller ID, and also make sure that the topology settings of the primary and secondary system ports are correct.
