RE: Tape order
Jean-Louis,
It seem that amadmin config tape figures out the order of the new tapes,
while amcheck, and I assume amdump, seems to use the tape in the first
available slot. Just a guess.
I already have a script that will look for unlabeled tapes and label, and I
have modified the script to sorts the tapes into the ascending slots in
ascending order after they are labeled.
This should resolve my problem.
Thanks
Robert

Ha, they are new tapes, there is no order for new tape, amanda use the
first one.
Put them in the changer in the oreder you want them to be used.

be
A00224 and will use tapes in slot 31-36.
Why the difference between the two command.?
amadmin list the order in which the tape should be used.
amcheck list the first tape it will use, it is your responsibility to
but the tape you want in the correct slot
chg-zd-mtx do not use the barcode, that's why the fiorst slot is always

RE: tape order
This is what I do to keep my tapes in sequence. Say I have the following tape list. 20061010200953 D00025 reuse 20061009201023 D00024 reuse 0 D00023 reuse 20061009141704 D00022 reuse 20061008200944 D00021 reuse I change the time for D00023 to something in between D00022 and D00024. Such as 20061010200953 D00025 reuse 20061009201023 D00024 reuse 20061009141904 D00023 reuse 20061009141704 D00022 reuse 20061008200944 D00021 reuse I have several L0 dumps so for me this is not a problem. It is best to do this as time gets closer to the date you want to change to. To keep things in order I always run sort -r oldtapelist new tapelist The output will be sorted as above. The next tape on my list is always the bottom tape. Since I have been running amanda (3 years) my daily tapes have always been in sequence. Now my amadmin config tape list the correct tapes that will be used next. There is no rocket science in what I am doing but it works for me. Robert _ Robert P.

Re: tape order
Forget about tape order. It's not important. AMANDA bases the order on what is expiring/expired. So just forget about tape order, it's going to get out of whack.

My tapecycle is 10. On the sticker used on the tape, do a double numbering, one by Amanda label and one by human sequence (13 a) (16 b) (15 c) (14 d) (17 e) etc. Though after many years of using Amanda I never had the tapes going out of sequence, if one tape wears out, I replace it with a new tape, using the same label (amlabel -f), but I do the replacement only the very day I should have been reusing the bad tape. When a dump resolve that tape 7 is faulty, I continue with tape 8 and etc, only when Amanda ask to use tape 7 again, I label a new tape 7 and use that new 7. I do that with a PostIt on the bad tape to remind me that I must replace that tape the next time I try to use it. Olivier
