Questions on /dev/*st*

[dennett at kodak.com]

I have a Sun 4/280 (4.0.3) with 2 scsi devices.  One is a 1/4" tape drive
the the other is a Exabyte drive.  The 1/4" drive has entries in the /dev
directory of rst0, rst8, rst16, and rst24 (plus the non-rewinding ones).
The Exabyte has rst1, rst9, rst17, and rst25.

According to the man pages st(4) (for 1/4") the rst0 is QIC-11 and the
rst8, rst16, and rst24 are all QIC-24.  Is there any difference between
the rst8, rst16, and rst24 entries?  Where might I find this difference
explained if in fact there is a difference?

Likewise, what, if any difference is there between the 4 entries for the
Exabyte drive, or do they all end up doing the same thing?

Thanks for any help.
