How to dedicate a set of slots and a drive to an amanda config

How to split one Tape Library to be used by several independant amanda configs

General info about devices used in the configs below:

Storage Changer /dev/sg2 is the the changer device /dev/sg2
Data Transfer Element 0 is tape drive /dev/nst0
Data Transfer Element 1 is tape drive /dev/nst1

Run mtx on the changer device to see all the slot and drive info:

-bash-3.00$ mtx -f /dev/sg2 status

FIRST CONFIG (Uses tape drive 0 and slot 1-10) to run Daily backups:
Example of an amanda.conf:

org "zmanda"    # your organization name for reports
mailto "[email protected]"     # space separated list of operators at your site
dumpcycle 7     # the number of days in the normal dump cycle
runspercycle 6          # the number of amdump runs in dumpcycle days
                       # (4 weeks * 5 amdump runs per week -- just weekdays)
tapecycle 10 tapes       # the number of tapes in rotation
                       # 4 weeks (dumpcycle) times 5 tapes per week (just
                       # the weekdays) plus a few to handle errors that
                       # need amflush and so we do not overwrite the full
                       # backups performed at the beginning of the previous
                       # cycle

                       # for each client host
