Okay - well I'm getting conflicting messages here.  I had previously
been using /dev/nst0 to access the tape drive.  That wasn't working,
so someone here told me I should use the sg* nodes to access the
drive.  So that's when I switched to /dev/sg2.  I changed the dev
entry in chg-scsi.conf back to /dev/nst0 and this is what I'm still
getting:

amanda@lpdlnx00 LPD $ amcheck LPD
Amanda Tape Server Host Check

Holding disk /dumps/amanda: 36514756 KB disk space available, that's plenty
amcheck-server: could not get changer info: could not read result from
"/usr/libexec/chg-scsi"
