My bet is that you could probably edit the sshd_conf file on the 3PAR
to force it to accept hmac-sha1-96.  I wouldn't want to do that on anything
touching the outside world and I might be a little nervous about doing that
on something touching a corporate network, but if it's a private net I don't
see why not to do it.
