The logical devices are not

recognized by the system.

Verify that the READY indicator lights on the disk

array are ON.

Verify that the cables are correctly installed and ﬁrmly

connected.

Check for bent pins on the connectors and

terminators.

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 connect two devices with the same ID on the

same bus.

TheNTsystemdoesnotreboot

properly after hard shutdown.

If the NT sy

stem is powered off without executing the

shutdown process, wait three minutes before restarting

it. This pause allows the disk array’s internal time-out

process to purge all queued comm ands so that it is

availa

ble (not busy) during system start-up. If the

NT syst

em i s restarted too soon, the disk array will

conti

nue trying to process the queued commands,

andtheNTsystemwillnotrebootsuccessfully.

The system hangs.

Verify that the target IDs/WWNs are set correctly

and are not duplicated.
