Table 6 Error conditions
Recommended actionError condition
Verify the following:The logical devices are not recognized
by the host.
• 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.
• The data in the emx_data.c file correctly maps each WWN to
a TID between 0 and 7.
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.
The host does not reboot properly after
hard shutdown.
Verify that the disk array logical devices are correctly formatted.Physical volumes cannot be created.
Verify that the volume capacity for OPEN-x volumes is not greater
than the maximum capacity allowed. See
“Disk array supported emulations” on page 33 for capacities.
Verify that the capacity of the volume group is not less than the total
capacity of the partitioned logical volume.
Logical volumes cannot be created.
Verify that logical volume name is a character-type volume.A file system cannot be created.
Verify that the host was restarted correctly.
Verify that the file system attributes are correct.
A file system is not mounted after
rebooting.
Reboot the host.The disk array performs a self reboot
because the disk array was busy or it
logged a panic message.
Contact HP.The disk array responds “Not Ready”
or the disk array has displayed “Not
Ready” and timed out.
Check the HBA and make sure it was installed properly.
Reboot the host.
The host detects a parity error.
Make sure there are no duplicate disk array TIDs and that disk array
TIDs do not conflict with any host TIDs.
The host hangs or devices are declared
and the host hangs.
