Uncompress (gunzip) and untar the release package.
Create a backup of the "inodes" using samfsdump. This is a precaution
and always a good idea.
cd /mount_point
samfsdump cf /path-to-backup
Make a copy your mcf file (precaution).
Make a copy of /etc/fs/samfs/inquiry.conf if you have added devices.
umount any mounted SAM-FS file systems and send sam-init a INT.
pkgrm LSCsamfs (if already installed)
pkgadd -d file-name (file-name is the uncompressed package file).
Verify the mcf file has not changed (pkgadd should not overwrite
this file) or create a new one (see notes below).
If needed, merge changes from your copy of inquiry.conf into
/etc/fs/samfs/inquiry.conf.
Reboot the system. The installation of SAM-FS installs a new
system call and a reboot is needed. Failure to reboot will cause
a PANIC when the file system is mounted.
