iozone is ok, but a little complex to run. Any disk benchmark will be ok - bonnie++, blogbench, etc. but each has an emphasis on a different aspect of the system. I think bonnie++ will be the simplest in your case. Make sure you know what you're benchmarking - for example if the iSCSI drive (target) is hosted as a file in a regular file system, it will be overly (and dangerously) cached on the server.
