next in thread | raw e-mail | index | archive | help
About a year ago, I see that there was a message on this list that
mentioned the warning message I'm now getting... but I didn't see a
followup or a resolution... so I'm asking for some assistance in
figuring out what is going on.
Background: I had set up a dedicated "backup server", running amanda
(2.4.2-19991216-beta1, with a few custom patches [some of which didn't
seem to catch the fancy of the amanda community, but which I found
useful, so I kept them in anyway]); the box was running FreeBSD 2.2.6-R
for a long time.
Since it's only in active use for a few hours each day, I had been
trying to set it up so I could boot it either from 2.2.6-R or 4.x-C
(a few months ago, before 4.0-R existed). Today, I decided to "upgrade"
the 4.0-C to 4.0-R -- actually, I did a re-install, overlaying the old
4.0-C. (This after running 4.0-R for several weeks on the laptop I'm
using to type this message... which is mostly serving xterms that are
opened up on various machines; quite handy, actually, for a sysadmin.)
After tweaking things here & there with the filesystem layouts,
re-building & re-installing amanda, and getting all the amanda
configuration stuff taken care of, things seem to work OK so far: I
haven't actually done a backup yet, but the "amcheck" works just fine.
But just as I was getting ready to leave the machine room, I glanced up
at the console (which I had inadvertently left on), and I saw a large
quantity fo messages like that in the Subject: -- e.g.
/kernel: ch: warning: could not map element source address 256d to a
valid element type
(The address in question rotated among 256d, 512d, 768d, 1280d, 1536d,
1792d, and 1280d. The changer in question has 7 slots. More below.)
Now, although I'm using a fairly recent version of amanda, I had started
with amanda about 1.5 years ago... and back then, there was no "changer
script" that appeared to be suitable that was distributed with amanda
(and I wasn't aware that someone else was working one one), so I cobbled
up a fairly simple-minded one (in Perl 5) that makes use of Jason Thorpe's
"chio" command to manipulate the changer... and I'm still using it.
(Please note that the functions appear to work -- I was able to get the
device to cycle through all the tapes, for instance -- it just spams
syslog with the warnings, is all.)
One of the things it does early on (for example) is issue "chio params"
and "chio status" commands (and parse the results of same) in order to
get a clue as to what the changer thinks its current configuration & status
is.
With that in mind, here are the results of the commands in question:
eng-backup# chio params
/dev/ch0: 7 slots, 1 drive, 1 picker
/dev/ch0: current picker: 0
eng-backup# chio status
picker 0:
slot 0: <ACCESS,FULL>
slot 1: <ACCESS,FULL>
slot 2: <ACCESS,FULL>
slot 3: <ACCESS,FULL>
slot 4: <ACCESS>
slot 5: <ACCESS,FULL>
slot 6: <ACCESS,FULL>
drive 0: <ACCESS,FULL>
eng-backup#
The warning messages in question appear to be generated in coincidence
with issuing the latter command ("chio params"). [Basis for this
observation is watching a "tail -f /var/log/message" while issuing the
above sequence of commands.]
Further, the message appears to be issued by code in cam/scsi/scsi_ch.c,
around lines 1036-1057:
if (desc->flags2 & READ_ELEMENT_STATUS_SVALID) {
eaddr = scsi_2btoul(desc->ssea);
/* convert source address to logical format */
for (et = CHET_MT; et <= CHET_DT; et++) {
if ((softc->sc_firsts[et] <= eaddr)
&& ((softc->sc_firsts[et] + softc->sc_counts[et])
> eaddr)) {
ces->ces_source_addr =
eaddr - softc->sc_firsts[et];
ces->ces_source_type = et;
ces->ces_flags |= CES_SOURCE_VALID;
break;
}
}
if (!(ces->ces_flags & CES_SOURCE_VALID))
printf("ch: warning: could not map element source "
"address %ud to a valid element type",
eaddr);
}
I confess, though, to being fairly unfamiliar with just what is supposed
to be going on here....
I'll copy the output of dmesg from a "boot -v" below my .sig; I'm
certainly willing to provide additional information, but the kernel
configuration (for example) differs from GENERIC (only) in that:
* I removed all the "cpu" directives but I686_CPU.
* I increased maxusers form 32 to 64.
* I decreased the SCSI "settle time" from 15 sec. to 5 sec.
* Lots of devices I didn't care about were commented out.
* The ch device (which I *do* care about!) was copied in from LINT.
* I added kernel support for (but have yet to enable) soft updates.
Thanks,
david
