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.
