Hello everyone:
I made the changes Jon LaBadie suggested on Friday. I also kicked
amtapetype and got the following for Dell PowerVault 124T:
# amtapetype -f /dev/nst0
Writing 2048 Mbyte compresseable data: 34 sec
Writing 2048 Mbyte uncompresseable data: 88 sec
WARNING: Tape drive has hardware compression enabled
Estimated time to write 2 * 1024 Mbyte: 88 sec = 0 h 1 min
wrote 5910198 32Kb blocks in 18074 files in 8350 seconds (short write)
wrote 5343303 32Kb blocks in 32781 files in 8346 seconds (short write)
define tapetype unknown-tapetype {
comment "just produced by tapetype prog (hardware compression on)"
length 206453 mbytes
filemark 1233 kbytes
speed 21568 kps
}
Now, there are two tapes currently in the unit but when I attempt the
following, I get a an error:
# su amanda -c "/usr/sbin/amtape DailySet1 show"
amtape: could not get changer info: cannot determine first slot
What else could be missing from my configuration?
Thanks,

Without a history of previous runs, I don't understand
how this will work. Maybe it does, I've not tried it.
If you are running amdump every day, use 7 or 0.
> tapecycle 7
Whoops. definitely not a good setting. You will be
overwriting on day 8, tape one, with the first set of full
dumps (on which the incrementals of day 2-7 are based).
An absolute minimum (though notrecommended any way no how!)
is runs/cycle + 1. A more reasonable minimum is twice that.
And I think that most sites work with higher multiples.
Those numbers for tapecycle also have to be increased based
on the number of tapes used per run (runtapes).

Looks like a linux system. You should check out the stinit
capability which will initialize several more device names
and each can have specific properties, eg. compression on/off,
block size, ...

I like the logs in a subdir rather than clutter up
the main config dir.

Few sites want the reserve at 100. This means 100% of
the holding disk is reseved for only incrementals.
Speaking of which, no holding disk defined. Gonna be
tough feeding that new drive fast enough unless you
have the buffering of a holding disk.

Without a holding disk, this doesn't matter, but I like
to have anything that didn't fit on to the tape automa-
tically flushed at the start of the next run.

I don't see changerfile defined. It should point at your changer.conf
file. Without the ".conf" specified for current chg-zd-mtx.
