I thought that as well and tried to change it to one slot in chg-manual
(firstslot=1 and lastslot=1), but with the same result.

I've now tried to direct the output from chg-manual to
/var/log/chg-manual.log instead of to /dev/tty, as per Dustin's
suggestion, but it doesn't work yet:

-rw------- 1 amanda disk      0 Jun 11 16:25 chg-manual.log

# su -c "amtape daily show" amanda
changer: got exit: 0 str: 1 2 1
changer_query: changer return was 2 1
changer_query: searchable = 0
amtape: scanning all 2 slots in tape-changer rack:
changer_find: looking for NULL changer is searchable = 0
changer: got exit: 0 str: 1 /dev/nst0
slot 1: date X        label daily-6
changer: got exit: 0 str: /usr/lib/amanda/chg-manual: line 86:
/var/log/chg-manual.log: Permission denied
slot /usr/lib/amanda/chg-manual:: tape_rdlabel: tape open: line 86:
/var/log/chg-manual.log: Permission denied: No such file or directory

I'll try adjusting the log file's permissions, and will try with only
one slot again.

Thanks for your replies.

Johan

I've not used chg-manual.  But is it reasonable that
the changer script thinks there are two slots available?
Maybe that is the way it is written, but it looks
strange to me that it should be looking for the
second slot in a manual tape drive.
