Error conditions
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.

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.
The host does 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
processing queued commands, the host may not reboot successfully.
Physical volumes cannot be
created.
Verify that the disk array logical devices are correctly formatted.
Logical volumes cannot be
created.
Verify that the volume capacity for OPEN-x volumes is not greater
than the maximum capacity allowed. See the Device Emulations
Appendix.
Verify that the capacity of the volume group is not less than the total
capacity of the partitioned logical volume.
