What to do if my HP Disk array system shows a general power failure?
In the event of a general power failure, turn off all PDU switches and breakers. Once the facility power is stable, turn them back on and power up the system. Refer to Chapter 4 for detailed instructions. If the issue persists, contact HP support for further assistance.
Why does HP Software initialization fail?
If the link initialization procedure to the remote HP Software system failed, ensure that the main and remote systems are physically and correctly connected. Also, make sure that you entered the correct remote system S/N, SSID, and path parameters (port, link address, logical address).
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.
What to do if HP XP P9500 Software monitoring data is not updated?
If the monitoring data is not updated in HP Software even when the Monitoring Switch is set to Enable, set Monitoring Switch to Disable, and set Monitoring Switch to Enable again, because the time setting of SVP is changed.
Why is my HP Software communication failing between primary and secondary systems?
The communication between the primary and secondary systems may have failed because the secondary system or network relay devices were not running, causing journal volumes to remain full even after the timeout period elapsed. To resolve this, remove the failure from the primary and secondary systems or the network relay devices. If necessary, increase resources such as the amount of cache, the number of paths between primary and secondary systems, and the parity groups for journal volumes. Then, restore the failed pairs.
What to do if HP Software pair suspended by M-VOL Failure?
If the user suspended the HP Software pair from the MCU using the M-VOL Failure 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.
What to do if I see a Program Error in HP XP P9500 Software?
If a program error is detected in HP Software, delete the path by using the Delete Path or Delete DKC command, and then add the path and the secondary system again by using the Add Path or Add DKC command.
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 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.
