-- LOCATION INFO
--
-- Generic storage information
-- ipnfsid : pnfsid of the inode
-- itype : type of storage, e.g. tape, disk
-- ilocation : type specific information like pool name for disk and HSM connetion for tape
-- ipriority : in case of multiple locations of hint for performance or other needs
-- ictime : location creation time
-- iatime : last access time, probably performance killer, but nice to have for statistics
-- istate : location status ONLINE/OFF-LINE
