Improper Device Type

Step 1.

Check to be sure that all the devices attached to a single SCSI bus
are of the same type.

Only low voltage differential devices must be attached to low
voltage differential SCSI channels.

When a mix of Ultra2/3 SCSI and Ultra SCSI devices are connected
to a single bus, the bus will run at the Ultra SCSI speed. Because the
bus will auto-adjust to the slowest speed, it is not recommended that
you run both Ultra2/3 SCSI and Ultra SCSI devices on the same
bus.

Caution

If in this procedure you determine that you need to replace a SCSI
device, all I/O to the SNC 5100 must be stopped and it must be
turned off.

Step 2.

Replace any improper SCSI device with a proper device.

Step 3.

Reconnect the SCSI cable.

Step 4.

If you do not have to replace an improper device, go to

"Examine

SCSI Cables"

.

If you replaced any devices, reboot the SNC 5100.

Step 5.

After the SNC 5100 finishes booting, enter the

scsiShow

command

from the service terminal.

For more information, see the

"scsiShow"

command on page 160.

Step 6.

Compare the list of attached devices with the physical devices.

If not all of the physical devices are shown, go to

"Examine SCSI

Cables"

.

If all of the physical devices are shown, go to

"SCSI Health Check"
