NAS Storage library and managed assets

 I need a NAS library for my server pool. On a managed asset, I manually created a zfs filesystem from an existing zpool and set the sharenfs attributes necessary to allow both the EC/PC and the servers that will form the server pool to access the share read/write. I then go to Ops Center and follow the procedure in Storage management chapter and follow procedure but managed assets drop down list is empty.  The BUI is implying that any NFS share on a managed asset would be discovered but since it isn't working that way I'm guessing that only applies to ZFS storage
