Ah, while coming to an end with this mail and considering to check
upstream (http://christophe.varoqui.free.fr/) whether they know about your
specific storage device, I found the infos you need to configure!

    wikis.sun.com/download/attachments/186238602/2010_Q1_ADMIN.pdf

Page 107+108 gives you all required / SUN recommended settings:

device
{
vendor                      "SUN"
product                     "Sun Storage 7310"
getuid_callout              "/sbin/scsi_id -g -u -s /block/%n"
prio_callout                "/sbin/mpath_prio_alua /dev/%n"
hardware_handler            "0"
path_grouping_policy        group_by_prio
failback                    immediate
no_path_retry               queue
rr_min_io                   100
path_checker                tur
rr_weight                   uniform
}

I guess ALUA is enabled by default on the SUN storage 7310, but check it.
