Another long-distance e-troubleshooting quandary:
Machine: SGI Personal IRIS 4D/20 (WDC 33C93A SCSI, single channel)
All disks pop up as unknown type, for instance the main system disk
comes up under the PROM as
Unknown SCSI type 191 / removable: scsi (0,1)
drive settings:
-ID: 1
-Time monitoring is disabled
-Read-Ahead caching is enabled
-Normal operational mode
-LED active when drive connected to bus
-CHECK CONDITION posted (unit attention response)
-Unlimited 250ms, 128 retries (scsi time monitoring)
-SCSI-2(scsi level)
-SAVE DATA POINTER is issued for disconnection (message mode)
-CHECK CONDITION status not posted(error report at mode select
parameter rounding)
-0 (PER default value)
-Motor start on power up (motor start timing)
-Executed by IDD (scsi bus parity check)
-CHECK CONDITION status not posted (synchronous mode transfer rate)
-Disabled (OPEN 1.2 to 2.67MB/s)
-Power is supplied to the terminating resistor from the IDD and TERMPWR
pin. Power is also supplied to the TERMPWR pin from the IDD. (Pin 26 of
the interface) (scsi terminating power)
new SCSI cable tried, terminator known working, drive visible from a
different machine (Linux PC). The devices pop up at the proper SCSI
IDs, but all are misidentified as Type 191 (I suppose this is a decimal
representation of the hex SCSI identifier numbers.) Is this likely a
dead 33C93A or is there somewhere else to look?
P.S. - we love you, Tony- Don't leave.
