HPSS always attempts to read a label at the beginning of a tape when performing an import. Some tape
drives and device drivers will report errors when asked to read unreadable tapes (as described above). If
this happens, manually write two tape marks at the start of the tape and retry the import. Most UNIX
systems provide the mt command, which can be used to write tape marks.
An HPSS label is basically just an ANSI label. A few characters are changed to identify the tape as
having been labeled by HPSS. Both label types are supported by HPSS; tapes already beginning with an
ANSI label are not relabeled unless the overwrite import option is selected and volume labels match.
