To: freebsd-scsi@freebsd.org Date: Thu, 15 Jun 2000 18:06:12 -0500 (CDT) X-Mailer: ELM [version 2.5 PL3] MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I've got a system with many(7) SCSI busses. One bus has nothing other than a tape drive and autoloader. When I eject the tape from drive, it executes correctly, but I get: # camcontrol eject 3:1:0 Unit stopped successfully, Media ejected (pass7:ahc1:0:0:0): SCB 0xd - timed out while idle, SEQADDR == 0xa ahc1: Issued Channel A Bus Reset. 1 SCBs aborted Which really makes no sense, considering I wasn't talking to that device: # camcontrol devlist *snip* at scbus3 target 0 lun 0 (pass7,ch0) at scbus3 target 1 lun 0 (sa0,pass8) *snip* Then, another random scsi bus (even on a different card) will reset: (noperiph:sym1:0:-1:-1): SCSI BUS reset delivered. Has anyone seen anything like this? dmesg follows: Copyright (c) 1992-2000 The FreeBSD Project. Copyright (c) 1982, 1986, 1989, 1991, 1993 The Regents of the University of California.
