Two things come to mind, one being that to find many of the changer robots, the kernel must be recompiled, enabled the 'scan all luns' option. The other being that devices are assigned in the order detected by the kernel, so whats at /dev/sg0, /dev/sg1, /dev/sg2, and /dev/sg3? This should all be reported in your /var/log/dmesg file. >This is the SCSI info from dmesg > >Vendor: HP Model: C5713A Rev: H910 > Type: Sequential-Access ANSI SCSI revision: 02 >Detected scsi tape st0 at scsi0, channel 0, id 4, lun 0 > Vendor: HP Model: C5713A Rev: H910 > Type: Sequential-Access ANSI SCSI revision: 02 >Detected scsi tape st1 at scsi0, channel 0, id 4, lun 1 > >and > >$ scsi_info /dev/st0 >SCSI_ID="0,4,0" >MODEL="HP C5713A" >FW_REV="H910" > >$ scsi_info /dev/st1 >SCSI_ID="0,4,1" >MODEL="HP C5713A" >FW_REV="H910" Logical Unit Number 1, the robot, is found and assigned to /dev/st1? Or does this library have two drives in it AND they are at different LUN's of the same address? >Now the issue is that in the IDC on an identical setup in > amanda.conf the changer device /dev/sg4 although the SCSI ID's from > dmesg are the same as my test setup? > >If in amanda.conf i set the changer device to be /dev/st0 or st1 i > get > >$ amcheck gt-host >Amanda Tape Server Host Check >----------------------------- >WARNING: holding disk /var/spool/amanda: only 1388716 KB free > (3072000 KB requested) >amcheck-server: could not get changer info: badly formed result from >changer: "failed to set sg timeout - Invalid argument" Which would be correct, its the Scsi Generic driver, sg for short, that is usually used to drive the robotics. >any thoughs as i'm stuck So am I without seeing another 30 lines worth of your dmesg after the above quoted snip. >thanks > >Tom -- Cheers, Gene AMD [EMAIL PROTECTED] 320M [EMAIL PROTECTED] 512M 99.26% setiathome rank, not too shabby for a WV hillbilly Yahoo.com attornies please note, additions to this message by Gene Heskett are: Copyright 2003 by Maurice Eugene Heskett, all rights reserved.
