amadmin delete hostname disk
Though in your case "disk" would be the directory, i.e. the DLE entry.
Then remove the entry fromt he disklist.

Vytas,
you aren't serious are you? You are so undertaped it is silly.
Every disklist entry you make must first receive a level 0 backup. That
alone will take about 50 tapes.
Then assume you are running dumps daily with a dumpcycle of 1 week.
Best case scenario is about 10 tapes per day with a mixture of about
8 for level 0's and 2 for incrementals (assuming only a 5 percent change
in data per day). With only 2 dumpcycles of tapes, that is 140 tapes.
And that only covers 3 systems out of 20 hosts that need backing up.
If they are similarly sized, that is 7 times more data, meaning 70 tapes/day?
There may not even be enough hours in a day. Assuming a data rate of 1MB/sec
(my 12GB DDS3 tape does that), it would take 2 hours of writing per tape.
You really must think about a different backup device.
