VMEbus Error
Occurred
A VMEbus error was detected while the adapter was transferring
either parameters or data.
1DH SCSI General Timeout
For Pass-through operations, this error will be reported if a SCSI
operation takes too long to complete.
1EH SCSI Select Timeout
For Pass-through operations, this code is reported when no SCSI
device responds to the selection sequence within the timeout period.
The timeout period is specified in the Unit Options command or
Extended Unit Options command.
1FH
SCSI Disconnect
Timeout
For Pass-through commands, this code is reported when a
disconnected SCSI device does not reselect the adapter within the
timeout period. The timeout period is specified in the Unit Options
