Jay Holt ---- The best answer !!!
Question:
1. Does Sun still support Solaris 1.1.2 or aka SunOS 4.1.4 ?
answer: YES
2. Will the 14 GB Sun Tape drive (8505-XL) work on Sun 670 and running with
SunOS 4.1.4 or aka Solaris 1.1.2 ? (Note that this tape drive was new as of
last year and SunOS 4.x is much older.)
As I understand from several of the answers, the manual that comes with the
14 GB tape drive explains how to install it on the older SunOS 4.1.4, I do
not have the manual since it is at the site I am needing to support. So I am
taking your word that it is in there.

The best answer was from Jay Holt. Here is his reply:
Yes, this can be done.
The following file must be modified to support
your tape device:
/usr/sys/scsi/targets/st_conf.c
You must add an entry for the exabyte 8505XL drive.
/* Exabyte 8mm 5GB compression half height cartridge */
{ "Exabyte EXB-8505 8mm Helical Scan", 16, "EXABYTE EXB-8505",
ST_TYPE_EXB8500, 1024,
(ST_VARIABLE | ST_BSF | ST_BSR | ST_LONG_ERASE | ST_KNOWS_EOD),
5000, 5000,
{ 0x14, 0x15, 0x8C, 0x8C },
{ 0, 0, 0, 0 }
},
Then you must do the following:
***** CONFIGURATION TASKS FOR SUNOS *****
REBUILDING YOUR KERNEL
All SunOS users must rebuild their kernels after modifying the
st_conf.c file.
To rebuild your kernel, do the following:
1. If prior changes have been made to your kernel configuration file, create
the kernel build directory using the /etc/config command. Otherwise, go to
step 2.
host# cd /usr/sys/<karch>/conf
host# /etc/config <KERNEL_CONFIG_FILE>
KERNEL_CONFIG_FILE = name of the kernel configuration file (e.g., GENERIC)
2. Rebuild the kernel using the make command. The resulting file is named
vmunix.
host# cd /usr/sys/<karch>/<KERNEL_CONFIG_FILE>
host# make
3. Save a copy of the original kernel file vmunix as vmunix.save until the
new
kernel file has been completely tested.
host# cp /vmunix /vmunix.save
4. Copy or move the new kernel file vmunix to the root (/) directory.
host# mv vmunix /vmunix
5. Reboot your system.

Answers from other Sun Managers that might help someone else:
Solaris 1.1.2 (aka SUNOS 4.1.4) will support 8mm 14GB, that's what
we are using now. SunOS 4.1.3 does not have support for 14GB drive, but
that is an instruction to hack the kernel to make it work
Yes, the drivers for 8mm shipped with Solaris 1.1.2 will work.
We use (currently) the 14G 8mm drive on our 4.1.2 670 machine. It required
an extra line to be edited into the SCSI configuration part of the kernal,
and then a recompilation of the kernal. The changes are documented in the
papers that come with the drive. The drive works perfectly.
Thanks again.
