Failure Detection and Troubleshoot-ing Guidelines

To choose the Continue response to a BIST error, press the left arrow key.

To choose the Loop response to a BIST error, press the right arrow key.

When your option, either/2233or &217, is displayed, press SELECT to

implement that option. indicates that the array will repeat that particular test if SELECT is pressed. &217skips the failed test and continues with the other BIST tests when you press SELECT.

Check or replace this

 

Check SCSI bus termination (single-ended arrays

 

only). Terminator may not be present, may be

 

broken, or the wrong kind.

 

Disconnect the array SCSI cable from Host and

 

reset the array. If BIST now passes, the problem

 

lies in the host system SCSI interface. Check the

(RROR￿￿￿￿8TGST￿￿￿￿

host SCSI adapter.

 

Verify Termpower. Check that the TPR jumper is

 

installed on the array controller board.

Meaning: External SCSI bus error.

Replace the array controller board.

 

 

 

 

Note

 

If a differential controller board is unterminated,

 

the BIST will complete without reporting the

 

unterminated condition. During subsequent

 

operation, various errors, apparently not related to

 

the termination, will occur. In the event of

 

unspecified error conditions, first verify that the

￿TGST(5525NCMG!￿XXXX

differential termination is in place.

 

Replace array controller board.
