Dear Wilko,
I have "DEC TZ87 (C) DEC 9514 type 1 removable SCSI-2" "density code 0x19"
tape drive. It works very well with MS WinNT. But with FreeBSD I met some
problems. If I use tar,dd, or simple "cat big.file > /dev/rst0" command fails
in random time with
st0(ncr1:1:0): Deferred Error: RECOVERED ERROR asc:a,0 Error log overflow
After light hack of st driver I find out that at this time
sense->error_code equals 113 (decimal). I add to st.c lines
(into st_interpret_sense(xs) function):
if(sense->error_code==113)
return ESUCCESS;
With that hack the tape seems to work right.
What is the reason for such TZ87's behaviour ?
NCR PCI 53c815 is my SCSI controller. FreeBSD-2.1, 2.2-SNAPs, 2.2-BETA (now)
Regards,
Sergey Kosyakov
