I decided I needed to read up on this and found RFC 3783 which is very
readable, highly recommended:

  http://tools.ietf.org/html/rfc3783

basically iSCSI just defines a reliable channel for SCSI.  the SCSI
layer handles the replaying of operations after a reboot or connection
failure.  as far as I understand it, anyway.
