| Just my personal, quick and dirty notes | |
| A tape LIBRARY or changer contains one or more tape DRIVES and they are addressed/used independently of one another (mostly) | |
| `mt` command is for tape drive(s) | |
| `mtx` command is for tape library/changer | |
| The library has the robot arm for moving tapes around, and slots for storage. The drives are... well, the drives. Like a VCR, for data. I guess then the library is like the Blockbuster. But for data. |

| # Background: this was done on a CentOS 6.5 ESXi VM running pmacct 1.5.0rc2 and PostgreSQL 9.3 from PGDG repo with | |
| # the following config line for pmacct: | |
| # | |
| # ./configure --enable-pgsql --enable-geoip --enable-ipv6 --with-pgsql-libs=/usr/pgsql-9.3/lib --with-pgsql-includes=/usr/pgsql-9.3/include | |
| # | |

| # I also customized the table they used in postgres to add vertical partitioning, but that's another gist :) | |
