SUMMARY: Exabyte FS4000 on Solaris 1.1.1/2.3?

Well, it turns out that Exabyte themselves came through!

I called their customer service center at 913.492.6002 and told them what
I wanted to do. They sent me a 19-page FAX detailing everything I ever
wanted to know about connecting *any* exabyte tape product to Solaris 1.X
and Solaris 2.X.

Anyhow, with SunOS 4.1.3[_U1], for an EXB-4200 and 4200c, the entries that
you make in /sys/scsi/targets/st_conf.c are:

/* Exabyte 4mm 2GB cartridge */
  "Exabyte EXB-4200 4mm Helical Scan", 16, "EXABYTE EXB-4200",
  5000, 5000,
  { 0, 0, 0, 0 },
  { 0, 0, 0, 0 }
/* Exabyte 4mm 4GB w/compression cartridge */
  "Exabyte EXB4200c 4mm Helical Scan", 17, "EXABYTE EXB-4200c",
  5000, 5000,
  { 0x63, 0x43, 0x0c, 0x0c },
  { 0, 0, 0, 0 }

A previous summary listed the steps to add this drive to a Solaris 2.X
machine; Exabyte's information differs from that in the summary. FYI, the
additions (as given by Exabyte) are:

tape-config-list =
  "EXABYTE EXB-4200", "Exabyte 4mm EXB-4200", "EXBT-4200",
  "EXABYTE EXB-4200c", "Exabyte 4mm EXB-4200c", "EXBT-4200c"

  EXBT-4200 = 1,0x34,1024,0x0029,4,0x63,0,0,0,3;
  EXBT-4200c = 1,0x34,1024,0x0029,4,0x63,0,0x13,0,3;

Exabyte also recommends that the following levels of code should be used
in the 4mm tape drives:

EXB-4200 No restriction, but recommend level 148 or higher
EXB-4200c Level 149 minimum (mode select for compression)

I have tested both configurations and they seem to work just fine.

My original message:

> Greetings and all that.
> We have recently been given 2 4mm Exabyte FS400 drives. These were
> originally intended for Intel-based systems, but through some mixup they
> ordered the wrong drives.
> Anyhow, I now have these things, and I'm trying to figure out how to get
> them to work on our Suns. We are running 4.1.3_U1 Rev B, and will be
> upgrading to 2.4 soon.
> What changes do I have to make to st_conf.c (and other files) to get
> these to work? probe-scsi reports
> removable tape EXABYTE EXB-4200c 124
> Any clues?
