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"
}
}
