Currently scsiinfo can print information from mode pages, but not log
pages. I have modified it to print log pages, but it's sort of a hack and
I only implemented the pages available on the Exabyte Eliant 820. I've
included the patch below anyway. It'd be nice if this patch or something
like it could end up in the standard .deb.
You need to uncompress scsiinfo/man8/scsiinfo.8.gz before applying the
patch. BTW, the patch also fixes some typos in the man page
("Miscanellous" and "pages pages").
