Dear All, Thanks to everyone who responded to my question about controlling a tape autochanger from Solaris 8. I received responses from:- Jonathan Loh Andy Bach John Rowan Littell Jeff Horowitz William Enestvedt Prabhala, Rama Ric Anderson Jordan Gaston Jon Burgoyne Responses ranged from 'You control this from the front control panel', which is difficult to script, through to those enlightered souls who pointed me in the direction of a program called mtx. I'll quote John Rowan Littell directly, as his advice was what I followed:- <quote> In a similar situation, I have an Overland DLT LoaderXpress on an E450/Solaris 8. I used the sgen driver to access the loader's management SCSI address. Look for the sgen driver config file in /kernel/drv/sgen.conf -- all of the entries are commented out by default. Then I got the mtx program from http://sourceforge.net/projects/mtx/. That lets me control the changer with commands like 'mtx -f /dev/scsi/changer/<target> load <slot>'. </quote> As John says, uncomment the lines in the sgen.conf file, and reboot, and lo and behold I have a /dev/scsi/changer/c4t0d0 device. Compile mtx (after downloading gcc and gmake from sunfreeware.com), and for convenience ln -s /dev/svsi/changer/c4t0d0 /dev/changer. and I'm running. Now I can do things like "mtx load 3" to load from slot 3, or "mtx unload", to put it back. Also rather wonderfully, it will read the barcodes from the tapes, so an mtx status will tell me where everything is. Very useful to put in backup scripts for reference. Jeff Horowitz reminded me to "make sure you have applied patch 110901-01, or it won't work!", which I can't comment on, since this patch was already applied, but others may need to heed his advice. I now have an easily controllable changer, which incidentally is actually an HP C7145-8000, at least that what it reports itself as. Thanks to everyone. Matthew. -- ------------------------------------------------------------------- Matthew Atkinson Phone: +44 (0) 1904 462120 IT Development and Unix Manager Fax: +44 (0) 1904 462111 Information Systems Team Central Science Laboratory E-mail: m.atkinson@csl.gov.uk Sand Hutton, York, YO41 1LZ, England Web: http://www.csl.gov.uk -------------------------------------------------------------------Received on Tue Oct 23 13:40:48 2001
