One command that every Networker
administrator will come to know well is nsrjb. Read & reread the man
page on this command, which both manages the jukebox & the volumes
or devices within the jukebox. While the Jukebox menu within the nwadmin
GUI allows access to much of the same functionality, several powerful options
-- nsrjb -H & nsrjb -IE -- are not available from the Jukebox menu.
This makes it a useful option to senior sysadmins who wish to restrict
junior admins to a subset of nsrjb's functionality.
Commands found in /etc/LGTOuscsi
enable a more fine tuning of the Legato's interface to the tape peripherals
than nsrjb permits. The man page describes them. (According to Stein Bjorndal,
these commands exist on the NT version of the server.)
In a post dated 27 Mar 2000,
Joseph Sleigh offered an example of using some of these commands:
If you want to check what
density a tape is, you can use the
msense command, e.g.
/etc/LGTOuscsi/msense -a x.x.x -p 0 | /etc/LGTOuscsi/pmode
where x.x.x is the scsi address
for your drive from the /etc/LGTOuscsi/inquire command. The output you
will get looks like
Mode Header: mdl=11 mtype=0x85 dparm=0x10 bdlen=8
Block Desc[0]: dens=0x85 nblks=0 blklen=0
Q. How can I get a list
of what's in my library from the command line?
nsrjb -Cv
mminfo -a -r 'volume(20),location(20), pool(15), %used'
No slot information, but others have shown how to get that.
