SCSI Send Diagnostics Test
The SCSI send diagnostics test runs the self-test for an
individual SCSI device. You can specify whether the test alters
drive parameters and includes a write operation.
To run the SCSI send diagnostics test, type
t 3/scsi/sdiag
scsi_id [
d
] [
u
] [
s
] and press Return.
When you type the SCSI send diagnostics command,
Replace
scsi_id
with the SCSI ID of the device you want to
test. The default SCSI ID is 0.
Include the optional d and u parameters to specify the
conditions that those parameters set for the specific drive
you are testing. Note that the result of including d and u
depends on the specific drive. To determine the effect of
including d and u, refer to the service guide for the drive
that you want to test.
Include the optional s parameter to suppress the error
message display.
