If the host hangs or devices are declared and the host hangs, ensure there are no duplicate disk array TIDs and that disk array TIDs do not conflict with any host TIDs.
What to do if the host does not reboot properly after hard shutdown on HP XP1024?
If the host does not reboot properly after a hard shutdown: * If you power off the host without executing the shutdown process, wait three minutes to allow the disk array's internal timeout process to purge queued commands. * If the host restarts while the disk array is processing queued commands, the host may not reboot successfully.
Why are my logical devices not recognized by the host on HP Storage?
If the logical devices are not recognized by the host, verify the following: * The READY indicator lights on the disk array are ON. * Fiber cables are correctly installed and firmly connected. * The target IDs are properly configured. * The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers. * The TIDs/WWNs on each bus are unique. * Do not install two devices with the same ID on the same bus. * Recheck the buses for new devices. * LUSE devices are not intermixed with normal LUNs on the same port. * The maximum number of LUSE devices per port has not been exceeded. * The disk array Host Mode is set correctly.
What to do if HP XP1024 Storage file system is not mounted after rebooting?
If a file system is not mounted after rebooting, verify that the host was restarted correctly and that the file system attributes are correct.
How to troubleshoot HP Storage logical devices not recognized by host?
If the logical devices are not recognized by the host, verify the following: * The READY indicator lights on the disk array are ON. * Fiber cables are correctly installed and firmly connected. * The target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers. * The TIDs/WWNs on each bus are unique. Do not install two devices with the same ID on the same bus. * Recheck the buses for new devices. * LUSE devices are not intermixed with normal LUNs on the same port. * The maximum number of LUSE devices per port has not been exceeded. * The disk array host mode is set correctly.
How to fix HP Storage logical devices not recognized by host?
To address logical devices not being recognized by the host with HP Storage, ensure the READY indicator lights on the disk array are ON. Verify that the fiber cables are correctly installed and firmly connected. Confirm that the target IDs are properly configured, with LUNs for each TID starting at 0 and continuing sequentially. Ensure TIDs/WWNs are unique on each bus, avoiding duplicate IDs on the same bus. Recheck the buses for new devices and confirm that LUSE devices are not mixed with normal LUNs on the same port, and that the maximum number of LUSE devices per port has not been exceeded. Finally, verify that the disk array host mode is set correctly.
What to do if HP XP1024 host hangs or devices are declared?
If your host hangs or devices are declared and then the host hangs, ensure there are no duplicate disk array Target IDs (TIDs) and that the disk array TIDs do not conflict with any host TIDs.
What to check if HP Storage logical volumes cannot be created?
If logical volumes cannot be created, verify that the volume capacity for OPEN-x volumes is not greater than the maximum capacity allowed (refer to Appendix B, Disk array supported emulations). Also, verify that the capacity of the volume group is not less than the total capacity of the partitioned logical volume.

Why does HP XP1024 disk array perform a self reboot?
If the HP Storage disk array performs a self-reboot because it was busy or logged a panic message, reboot the host.
