Thanks for your link, nevertheless I made those changes about alua an LUNZ but it seems that it's getting worse :
multipath -v2 -d gives :
sdg: checker msg is "directio checker reports path is down"
sdm: checker msg is "directio checker reports path is down"
sde: checker msg is "directio checker reports path is down"
sdk: checker msg is "directio checker reports path is down"
sdc: checker msg is "directio checker reports path is down"
sdi: checker msg is "directio checker reports path is down"
create: mpath0 (360026b905367200012a8666a06b52fbc) DELL ,PERC 6/i

Hi,
for other purposes I came to this document that refers to a CLARiiON
CX4-480 with CentOS 5.5:
http://www.nxnt.org/2010/08/multipath-linux-and-emc-clariion/
I don't know how does it match your config, but it seems that the
possibly relevant configuration differences are
hardware_handler "1 alua"
and
product_blacklist LUNZ (without the underscore...)
HIH,
Gianluca
