DM multipath :iscsi lun shows by diff names on two server where its exported

Hi,

I am trying to setup multipathing (using DM multipath) for a redhat cluster setup ...all setup is done but issue is :

node 1 shows the shared iscsi lun as sdc
node 2 shows the same as sdg (changes on reboots)

Due to this (i guess) i get i/o error & i can not read files created by other node. eg

Code:

[root@rh600 Packages]# cd /var/www/html/
[root@rh600 html]# ls
ls: cannot access index.html: Input/output error
index.html  lost+found  test
[root@rh600 html]#
 
[root@rh500 html]# ls -l
ls: cannot access index.html: Input/output error
total 13
-????????? ? ?    ?        ?            ? index.html
drwxrwxrwx 2 root root 12288 Nov  2 21:32 lost+found
-rw-r--r-- 1 root root     5 Nov  2 21:39 test
[root@rh500 html]#

Anyone knows work-around for this ?

Thanks in advance
