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
/223 or &217, is displayed, press SELECT to
implement that option.
/223 indicates that the array will repeat that particular
test if SELECT is pressed.
&217 skips the failed test and continues with the

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

host SCSI adapter.

Verify Termpower. Check that the TPR jumper is
installed on the array controller board.
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
differential termination is in place.
