PROBLEM DESCRIPTION:
SBus Timeout errors occur during back to back writes using FDDI/S 5.0 board
on Ultra systems. The errors arise due to a marginal timing problem. Typical
error messages are as follows...
unix: NFS write error on host LTU1: Stale NFS file handle.
unix: (file handle: 304484f 4d450000 0 0 b4ed b0198 21228000 0)
unix: WARNING: SBus0 Primary Error Timeout: AFSR 0x40000020 00000000
AFAR 0x000001ff 0000804c Id 31
Another failure symptom that may be experienced is that the SAS board hangs
under heavy load.
All FDDI 5.0 SBus cards the version 1.0 PLD chip are affected. Positive
identification can be achieved by viewing the label on the PLD at
location U16 on the SBus adapter. If the Label shows "650-0336-01 Rev.
1.0"
the board is affected. If the label shows "650-0336-02 Rev. 1.1" the
board
is not affected by this problem. It is expected that the FDDI/S 5.0 boards
in the following range of serial numbers are suspect;
5100012702
This problem was corrected in October 1996 in Sun Manufacturing when the
vendor implemented the use of version 1.1 PLD chip in place of the
version 1.0 PLD chip.
IMPLEMENTATION:

REPLACEMENT TIME ESTIMATE:
SPECIAL CONSIDERATIONS: 30 minutes
CORRECTIVE ACTION:
Replace upon failure with the following as applicable:
370-2339-01 SAS FDDI 5.0 with version 1.1 PLD chip at U16,
or with "DPCO_120" label
370-2340-01 DAS FDDI 5.0 with version 1.1 PLD chip at U16,
or with "DPCO_120" label
OR
370-3142-01 SAS FDDI/S 5.0 w/2-piece backpanel
370-3143-01 DAS FDDI/S 5.0 w/2-piece backpanel
