Step 1. Issue the scsiShow command from the service terminal to display
a list of attached SCSI devices.
For more information, see the
"scsiShow" command on page 160.
Step 2. For each SCSI channel, make a list of attached devices. Include
SCSI device ID, manufacturer, and device status/flags.
Step 3. Go to "Compare Listed versus Physical Devices".
Compare Listed versus Physical Devices
For each SCSI channel, compare the list of attached devices with the physical
devices.
If any of the physical devices are not shown, go to “Check SCSI Bus
Termination” on page 53.
If all the physical devices are shown, go to "Compare Listed versus Supported
Devices".
Compare Listed versus Supported Devices
Step 1. Compare the attached devices to the list of supported devices listed.
Step 2. If the attached devices are all supported, go to “SCSI Loop Back
Test” on page 58.
If any attached devices are not supported, report them to the system
administrator for possible replacement.
Caution
If all other diagnostic procedures fail to isolate a SCSI problem, and
there are unsupported SCSI devices attached to the SNC 5100,
those devices will need to be removed or replaced.
