In the archives, on May 6, 1997, you said about "amanda/Archive DAT
changer problem solved":
We've finally gotten Amanda working correctly with our Archive 4mm DAT
changer (4586NP). First, 2.2/3.0 now has the chio SCSI changer code from
NetBSD incorporated. Second, Amanda 2.3.0.4 from ftp.gps.caltech.edu
includes a seagate-changer program that can control the changer directly
using the chio mechanism. This has been a long standing problem for us
and just thought that I point it out if somebody else is using a similar
configuration.
On that recommendation and a few others here recently, I got one from
www.instantauction.com for $175. This changer holds 4 4mm DATs in an
internal cassette with built-in changer mechanism. Seems happy to run
with dump and manual amanda (I'm an amanda newbie but it looks like
exactly what I need).
Problem is I can't get the changer part to work. I'm running
FreeBSD-2.2-Stable, cvsupped a week about a week ago. I compiled in
support for ch0 in the kernel and it's recognized at boot:
(ncr0:6:0): "ARCHIVE Python 28849-XXX 4.CM" type 1 removable SCSI 2
st0(ncr0:6:0): Sequential-Access
st0(ncr0:6:0): 5.0 MB/s (200 ns, offset 8)
density code 0x13, 512-byte blocks, write-enabled
(ncr0:6:1): "ARCHIVE Python 28849-XXX 4.CM" type 8 removable SCSI 2
ch0(ncr0:6:1): Medium-Changer 4 slots, 1 drive, 1 picker
Some of the chio commands don't work, most notably "status":
operator@thanatos<17> chio status
chio: /dev/ch0: CHIOGSTATUS: Input/output error
After such a failure, the logs show the following, three times:
Oct 9 09:19:38 thanatos /kernel: ch0(ncr0:6:1): extraneous data discarded.
Oct 9 09:19:38 thanatos /kernel: ch0(ncr0:6:1): COMMAND FAILED (9 0) @f0642800.
Others do work, including movement from drive to slot#, and slot# to drive:
operator@thanatos<18> chio params
/dev/ch0: 4 slots, 1 drive, 1 picker
/dev/ch0: current picker: 0
operator@thanatos<19> chio move drive 0 slot 0 [does the right thing]
operator@thanatos<20> chio move slot 3 drive 0 [does the right thing]
I can't get *anything* to work with the Amanda "seagate-changer"
command. I had to tweak it a little, adding "#ifdef HAVE_CHIO",
changing the include to "<sys/chio.h>", and changing the name of the
function name "isnumber" to "myisnumber". Still, no joy -- IOCTL
failures:
operator@thanatos<26> seagate-changer -info
ioctl failed: 0xffffffff Input/output error
operator@thanatos<27> seagate-changer -reset
ioctl failed: 0xffffffff Input/output error
operator@thanatos<28> seagate-changer -eject
ioctl failed: 0xffffffff Input/output error
Syslog logs the same message, three times each, for each of the above
command failures:
Oct 9 09:25:19 thanatos /kernel: ch0(ncr0:6:1): extraneous data discarded.
Oct 9 09:25:19 thanatos /kernel: ch0(ncr0:6:1): COMMAND FAILED (9 0) @f0642800.
Can someone who's gotten this working tell me how you did it, or what
I'm doing wrong that "chio status" and "seagate-changer -info" fail?
Many thanks.
