Okay now I see that asm_disk33 is properly added to the multipath of node 2.
No problems there.

Node 2 multipath.conf.

asm_disk33 (360a98000647064512f2f46745a574646) dm-63 NETAPP,LUN
[size=200G][features=1 queue_if_no_path][hwhandler=0][rw]
\_ round-robin 0 [prio=8][enabled]
 \_ 5:0:4:122  sdgt 132:144 [active][ready]
 \_ 5:0:5:122  sdgu 132:160 [active][ready]
\_ round-robin 0 [prio=2][enabled]
 \_ 5:0:2:122  sdgr 132:112 [active][ready]
 \_ 5:0:3:122  sdgs 132:128 [active][ready]

So, according to this I m giving you the following plan:

You
Create those alias manually on non-working nodes(Node 2),
# cd /dev/oracleasm/disks
# mknod <ASMLIB Label Name> b <Major_number> <Minor_number>
# chown oracle:oinstall <ASMLIB Label Name>  (oracle:oinstall may be changed according to your environment, check the other disks in /dev/oracleasm/disks and chown accordingly)

Then do
# oracleasm scandisks
# oracleasm listdisks
