Description Andrew Macpherson 2001-03-17 19:31:42 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.72 [en] (X11; U; Linux 2.2.16-3 i686)

The ECRIX tape changer takes about 70 secs to unload a tape, causing the
/dev/sgN driver to time out (sg.h has
#define SG_DEFAULT_TIMEOUT (60*HZ) /* HZ == 'jiffies in 1 second' */
The tape changer being a sensitive soul goes into severe sulks when the
timeout causes a scsi abort, only cured by power cycling.

Reproducible: Always
Steps to Reproduce:
1. attach ECRIX tape library
2. configure AMANDA to use chg-zd-mtx
3. try to label a series of tapes to get going ie
amlabel <MYCONF> <MYLABEL>-1 slot 1
amlabel <MYCONF> <MYLABEL>-2 slot 2

Actual Results:  Mar 17 18:00:48 awning kernel: scsi : aborting command due
to timeout : pid 4155, scsi1, channel 0, id 5, lun 0 Move medium/play
audio(12) 00 00 00 00 52 00 06 00 00 00 00
Mar 17 18:00:48 awning kernel: sym53c8xx_abort: pid=4155 serial_number=4186

Expected Results:  command completion

problem cured by setting 


in scsi/sg.h and compiling new kernel

Problem is independent of SCSI card, reproduced on both Adaptec aha7xxx and

That would be a problem and decision for the kernel group - reassigning.

Comment 2 Bugzilla owner 2004-09-30 15:38:56 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
