FreeBSD 3.2-STABLE i386, and a
sa0 at ncr0 bus 0 target 5 lun 0
sa0: <WANGTEK 5525ES SCSI 73Y1> Removable Sequential Access SCSI-2 device
sa0: 4.901MB/s transfers (4.901MHz, offset 8)
tape drive on a NCR PCI SCSI host. I'll append a boot -v
dmesg below.
>Description:
1. mt bl(ocksize) stopped working, regardless what blocksize
i try i only get
mt: /dev/nrsa0: blocksize: Invalid argument
and on the console:
Apr 27 16:00:47 saturn /kernel: (sa0:ncr0:0:5:0): MODE SELECT(06). CDB: 15 0 0 0
c 0
Apr 27 16:00:47 saturn /kernel: (sa0:ncr0:0:5:0): ILLEGAL REQUEST asc:26,0
Apr 27 16:00:47 saturn /kernel: (sa0:ncr0:0:5:0): Invalid field in parameter lis
t sks:8f,4
2. mt erase fails similarly (I don't have the syslog right
now, sorry)
3. depending on factors i haven't found out, trying to read
after a BLANK CHECK on some tapes ends up hanging the entire
SCSI bus, printing this on the console:
ncr0: SCSI phase error fixup: CCB already dequeued (0xf07e1200)
followed by several of
ncr0: timeout nccb=0xf0xxxxxx (skip)
and
vm_fault: pager read error, pid xxx (process)
CAMDEBUG tells me on the tapes where it hangs it does
five LOAD UNLOAD commands (the first rewinds the tape) while
normally it does only one LOAD UNLOAD. I can send the full
CAMDEBUG output of the working case if that helps...
>How-To-Repeat:
1.
<load any tape>
$ mt bl <anything>
2.
<load scratch tape>
$ mt erase
3.
<load problem tape>
$ mt eom
$ dd bs=5k </dev/nrsa0 >/dev/null
dd: stdin: Input/output error
0+0 records in
0+0 records out
0 bytes transferred in 0.010533 secs (0 bytes/sec)
<console prints:

<tape rewinds, then it hangs the SCSI bus like explained above>
>Fix:
??? FWIW, all this worked on 2.1-stable...
(case 3 didn't rewind automatically, just repeated the
BLANK CHECK error; I don't know if that is/was a feature)
Here is the dmesg,
