SubjectRe: 2.4.19: sym53c8xx problems

Hello Eyal , I have a CP6000 unit (PPRO's tho) & am having no
such difficulties . Now that said I rebuilt the WHOLE scsi
layout in the system in order to get rid of those older hotswap
cages (imo, they stink electrically) . Btw , Stable as heck .
Wheres that forest I need to knock on ;-)

Is your scsi setup easy enough to make an ascii art description
of ? If so would you post it please ? From the messages below
it appears (to me) that their is some difficulty in the chain that
attaches to the python . I have never seen those messages when I
have attached (albeit differant) tape drives , ie: DLT,dat2,dat3 .
