Add an 'enclosure_symlinks' option to vdev_id.conf. This creates consistently named symlinks to the enclosure devices (/dev/sg*) based off the configuration in vdev_id.conf. The enclosure symlinks show up in /dev/by-enclosure/<prefix>-<channel><num>. The links make it make it easy to run sg_ses on a particular enclosure device. The enclosure links are created in addition to the normal /dev/disk/by-vdev links. 'enclosure_symlinks' is only valid in sas_direct configurations.
