next in thread | raw e-mail | index | archive | help
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*
<EXABYTE Exabyte EZ17 1.06> at scbus3 target 0 lun 0 (pass7,ch0)
<EXABYTE EXB-89008E00012F V41b> 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:
