It is most likely because there is an entry in the multipath code for
your array.  From what you say I'm guessing this is probably it (from
libmultipath/hwtable.c):
	r += store_hwe(hw, "SUN", "StorEdge 3510", MULTIBUS, DEFAULT_GETUID);

If you want to override the code setting, you have to put a specific
"device" section into /etc/multipath.conf, e.g.
devices {

       device {
               vendor                  "SUN"
               product                 "StorEdge 3510"
               path_grouping_policy    failover
               getuid_callout          "/sbin/scsi_id -g -u -s"
       }
}
