Thanks Alex, Yes, I can get open-iscsi working with iscsi. The problem is both ofed and open-iscsi install iscsiadm, so there's a conflict here and I haven't figured out what's the relationship in between. Besides, my centos box is working on iser using ofed. Does anyone know the history between ofed and open-iscsi?

This is supported in the official CentOS repos. You just need to yum install iscsi-initiator-utils iscsiadm -m discovery -p <targetip> -t sendtargets iscsiadm -m node -p <targetip> -T <target iqn reported by prev cmd> -l Then the block device nodes appear - as if by magic - under /dev/disk/by-path/ I'm not familiar with ofed, but it sounds like it requires you to reconfigure and rebuild your kernel.
