MSL G3 scsi commands

Greetings,

OK, in a nutshell I thought that if I could find the scsi commands for the robot I could use the generic scsi driver on VMS to load and unload tapes by writing a quick and dirty little tool.

The robot itself is the $2$GGA0: device on VMS which is loaded utilizing the generic SCSI device driver SYS$GKDRIVER.

Device $2$GGA0:, device type HP MSL G3 Series, is online, shareable.

Error count 0 Operations completed 0
Owner process "" Owner UIC [SYSTEM]
Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G:RWPL,W:RWPL
Reference count 0 Default buffer size 0
WWID 02000008:5001-10A0-008B-86F8

Theoretically I could write a tool that will communicate with the GGA0 device using the VMS QIO interface to the generic scsi driver.

SYS$QIO([efn] ,chan ,func ,iosb ,[astadr] ,[astprm] ,p1 ,p2 [,p3] [,p4] [,p5] [,p6]) where p1 is the address of the scsi command descriptor.

So, if I can find the scsi commands to cause the robot to load/unload tapes we would have a handy little tool.

I will continue to search SCSI web sites as well as the manufacturers support pages but any help would be nice. Actually if anyone knows of such a tool all the better…

Have Fun,

Re: MSL G3 scsi commands

Greetings,

Well... Not so much fun for me but I found an OpenSource tool that does what I need and it has already been ported to VMS.

Anybody out there have any experience with mtx?

(NOTE: I officially award myself 10pts ;^})

Have Fun,
