we do igroup show to know the hosts in the igroup.now it lists both the fcp and iscsi hosts in the igroup.

now my question is  ->  for fcp they are the wwpns of hosts listed .if so what is for iscsi are they wwnn or wwpn or iscsi node?

The most precise answer is.....neither. iSCSI goes by what are called "iqns" -- something like "iqn.1998-01.com.vmware:esx10-3f9da30d". Great info on the format here....

You can mix in CHAP as well for higher security (basically a single shared password).

iscsi is represented using iqn naming conventions,

They are nodes. You can use igroup show -v <initiator_group> to list members of the particular group and get a verbose listing.
