Can someone explain how iser and srp find the target devices?
Sean,
iser is no more (and no less...) then iscsi transport provider (another
in-kernel transport provider is iscsi_tcp) in the framework of the linux
open iscsi initiator. So with this 'i' at hand things --all-- go with IP
addressing.
The initiator management is done by user space daemon, where the first
stage is "target discovery" this is done using IP only and is beyond the
scope here.
Once the the target IP is known, the user space daemon attempts to login
into the target, here iser comes into play and we connect through the
rdma cm (see iser_connect() in iser_verbs.c), so with this dst IP at
hand the rdma cm resolves for us: locally the hca/port/pkey, then the
remote gid, then the path, then connect.
Or.
