Hi:

I never asked a question about this but saw some enquiries. It caused me
pain and Sun SUpport didn't even know they sold it! so I thought I'd
hopefully alliviate someone elses pain. To get the 2.5Gb you do need
a high density tape supposedly and these settings:

Solaris 2.5 has the entry for the drive in /kernal/drv/st.conf so this
is for 2.4 and below -
Add to /kernal/drive/st.conf:

# For a FIXED blocksize
tape-config-list=
"TNADBERG TDC 4200", "TANDBERG 2.5 Gig QIC","TAND-25G-FIXED";
TAND-25G-FIXED=1,0x37,512,0x867a,1,0x00,0;
TAND-25G-VAR=1,0x37,512,0x867b,1,0x00,0;

#For a VARiable blocksize
tape-config-list=
"TNADBERG TDC 4200", "TANDBERG 2.5 Gig QIC","TAND-25G-VAR";
TAND-25G-FIXED=1,0x37,512,0x867a,1,0x00,0;
TAND-25G-VAR=1,0x37,512,0x867b,1,0x00,0;

SunOS 4.1.X:
add to /usr/kvm/sys/scsi/targets/st_conf.c (Requires remaking kernal)

/* Tandberg 2.5 Gig Qic */
{
        "Tandberg QIC 2.5 Gig QIC", 17, "TANDBERG TDC 4200",
        0x37,512,
        (ST_QIC| ST_BSF| ST_BSR| ST_AUTODEN_OVERRIDE| ST|LONG_ERASE),
        400, 400,
        {0x00, 0x00, 0x00, 0x00},
        {0, 0, 0, 0}
}

e.g. On 4.1.X to make a new kernal: (as root)
        - cd /usr/kvm/sys/`arch -k`/conf
        - cp GENERIC NEWTAPE
        - config NEWTAPE
        - cd ../NEWTAPE
        - make
        - cp /vmunix /vmunix.old
        - cp vmunix /vmunix
        - reboot.

Hope this helps somebody.
