This depends on your library and how the LUNs are presented. Some libraries 
present each device as a target and not individual LUNs under a target so if 
you had 5 devices your st.conf would look like this:

name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=1 lun=0;
name="st" class="scsi" target=2 lun=0;
name="st" class="scsi" target=3 lun=0;
name="st" class="scsi" target=4 lun=0;

Some devices may need a config like this:

name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=0 lun=1;
name="st" class="scsi" target=0 lun=2;
name="st" class="scsi" target=0 lun=3;
name="st" class="scsi" target=0 lun=4;

Just avoid putting to many entries in st.conf because it does generate some 
overhead. A useful command to use when adding FV devices (disks as well) on 
Solaris: cfgadm -o show_FCP_dev -al

Hope this help,
