This patch fixes a problem with the cpio command in which cpio fails to create
multiple archives on 150 MB or 250 MB tape.  The system displays the following
error message:

        /dev/CTAPE1 weof 1 failed: I/O error
        ERROR: Cpio operation failed.

error message. The problem occurs when a tape drive is plugged into the slot
previously occupied by a disk.

This patch fixes an ASE NFS problem that occurs on ASE systems with KZPBA 
disk controllers. The system crashes with a "simple_lock timeout" panic.

ASE NFS services send the aseagents for most or all nodes into an
uninterruptable state:

Under certain conditions, the message "ctape_strategy: READ case and density
info not valid." was being printed for every read from tape.  This change will
print the message only once.
