Recommended Action
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 the disk array host mode is set correctly.
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.
Verify that the disk array logical devices are correctly formatted.
Verify with the appropriate utility (MAPPER or fcscan) that disk array
devices are recognized by the host system.
Verify all components of the SYSGEN I/O configuration pertaining to
the disk arrays.
