Oracle RAC11gR2 （ASM）
RHEL 5.8
FAS 3210
a two nodes Oracle RAC on RHEL 5.8.both 2 nodes will restart while halt a controller.
Oracle ASM lost diskgroup at that time and never recover in 200s(Oracle RAC default disktimeout)
At the same time,all my vmware esxi goes well.
here is my multipath configuration:

flush_on_last_del yes
max_fds max
pg_prio_calc avg
queue_without_daemon no
user_friendly_names no
