What to do if the HP Storage host does not reboot properly after hard shutdown?
If the HP Storage host does not reboot properly after a hard shutdown, 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, it may not reboot successfully.
What to do if HP Storage logical devices are not recognized by the host?
If your HP Storage logical devices are not recognized by the host, take the following steps: * Verify that the READY indicator lights on the disk array are ON. * Verify that fiber cables are correctly installed and firmly connected. * Verify that the target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers. * Verify that 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. * Verify that LUSE devices are not intermixed with normal LUNs on the same port. * Verify that the maximum number of LUSE devices per port has not been exceeded. * Verify that the disk array host mode is set correctly.
Why does my HP XP1024 host hang or declare devices and then hang?
