We need to install Oracle 11G and ASM point of view both node need to see same disk, generally multipath point of view when nodes come up its possible to see different LUN with different mapth name and its cause an issue for install oracle
There is an file under /etc/multipath which name is bindings , you can see that world wide name of disks and multipath names there.
What i did , take the one of node config file information as a baseline and copy it to other, then everything become okay, we do not have any issue of Oracle ASM configuration time about disk.
Related configuration is like below, hope its help for all
[root@kahin02-11g ~]# cat /etc/multipath/bindings
# Multipath bindings, Version : 1.0
# NOTE: this file is automatically maintained by the multipath program.
# You should not need to edit this file in normal circumstances.
