From 78adacd4eab39a3508bd8c65f0aba94fc6b907ce Mon Sep 17 00:00:00 2001 From: "Kenneth D. Merry" Date: Thu, 10 Dec 2020 21:06:06 +0000 Subject: [PATCH] Add the LTO-9 density code to libmt and the mt(1) man page. These values are taken directly from the density report from an IBM LTO-9 tape drive. (Using mt getdensity) A LTO-9 drive stores 18TB raw (45TB with compression) on an LTO-9 tape. lib/libmt/mtlib.c: Add the LTO-9 density code, and bpmm/bpi values. usr.bin/mt/mt.1: Add the LTO-9 density code, bpmm/bpi values and number of tracks. Bump the man page date.
