Mmmm, from your subject I can see that you have a query about your disks, partitions, etc.
Similar to SAM would be 'admintool' but doesn't give you any info about your disks. It only deals with basic admin issues.
mayby df -k will do a bdf for you.
maybe mount. maybe commands start with fs.... but you have to be carefull.
do a 'man -k volu' or 'man -k "something you thing is relevant"'
