For the initiator side, you can see the documentation that comes with
OFED. For the target side, use the wiki page (updated it only last week):

https://wiki.openfabrics.org/tiki-index.php?page=ISER-target

I saw that you were asking about a RPM. There are RPMs for SuSE & RedHat
on the wiki page. These RPMs will be included in OFED 1.4.

Yes - on the initiator side, do the following:

seed1:~ # iscsiadm -m session
iser: [1] 192.168.10.63:3260,1 iqn.2001-04.com.noni-seed1

You can see that iSER is used.

On the target side, do the following:

noni:~ # tgtadm --lld iscsi --op show --mode target
Target 1: iqn.2001-04.com.noni-seed1
    System information:
        Driver: iscsi

                RDMA IP Address: 192.168.10.81 <-- "RDMA IP Address"
means that iSER is used
