igroup

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?

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

Re: igroup

hey thankyou for ur kind reply,

but dude  why they are nodenames for iscsi as  they are port names in case of fcp? can u digg out more into this

Re: igroup

iscsi is represented using iqn naming conventions,

Re: igroup

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).
