Dear Sirs.

Can anyone explain the effect of this kernel option?

options         SA_1FM_AT_EOD

The reason for this question is, that we have massive problems
utilizing afbackup 3.3.5/6 and the new afbackup 3.3.7pl3 with
FreeBSD versions behind 4.6-RELEASE. Since FreeBSD 4.6-RELEASE
work with the HP SureStore 40x6i autoloader (afbackup
is capable of changing tapes via chio when the end of tape has
been reached), FreeBSD 4.6.2-pl2 and FreeBSD 4.7-RELEASE does definitely not
and I can not figure out what's going wrong.
I get errors from the kernel/SCSI device like this:

rror: device is not open for writing.
sym0:5:control msgout: 80 6.
sym0:5:control msgout: 80 6.

(sorry, message was truncated due overflow)

changing tapes via chio works fine and this works also fine with
the utility afbackup delivers, but this does not work anymore
after afbackup has reached the end of the tape!

Is anyone capable of giving a hint, a tip or something else?

Are there so rare FreeBSD servers utilizing big backup systems?
What's about other libraries, autoloaders, utilized via afbackup,
do the have the same problems?

Many thanks in advance,
Oliver
