Error Condition Recommended Action
The logical devices are not recognized by the host.
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
normalLUNsonthesameport.
Verify that the maximum number of LUSE devices per
port has not been exceeded.
Verify that the disk array host mode is set correctly.
Verify the data in the emx_data.c file correctly maps
each WWN to a TID between 0 and 7.
The host d oes not reboot properly after 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 process
ing queued commands, the host may not
reboot successfully.
Physical volumes cannot be created.
Verify tha t the disk array logical devices are correctly
formatted.
Logical volumes cannot b e created.
Verify that the volume capacit y for OPEN-x volumes is
not greater than the maximum capacity allowed. See
Disk array supported emulations for capacities.
Verify that the capacity of the volume group is not
less than th e total capacity of the partitioned logical
volume.
A file sy
stem cannot be created.
Verify
that logical volume name is a character-type
volume
.
A file system is not mounted after rebooting. Verify that the host was restarted correctly.
Verify that the file system attributes are correct.

array has displayed “Not Ready” and timed out.
Contact HP.
The host detects a parity error. Check th e HBA and make sure it was installed
properly.

Make sure there are no duplicate disk array TIDs and
that di sk array TIDs do not conflict with any host TIDs.
