    I've noticed that several people are using exabytes for LMFS backups.  I
    have a comment and a question regarding this.

    The comment (actually a warning):  Don't try this with the exabyte on a
    Sun running 4.1.1.  It will crash your sun!

    The question:  What is the proper bpi to use for a LMFS backup?  I've
    tried 54,000 (as stated in Sun's doc) but a complete backup still wants
    to use more than one tape for 500 MB of data.  I've also tried 43,200
    bpi.  But, the backup is still > 1 tape.

    Any help would be appreciated.

Meta-. tape:*cart-max-length* or tape:get-cart-guaranteed-capacity

I cannot remember what the hack is, but you can override the default
tape lengths fairly easily.

The folks to ask are S-graphics customers. They are often very intense
exabytes tape users and I'm sure make full use of the medium.
