RHEL5 dual-path (HDLM) support?

[Young, Mike]

Hello,

I have installed 2 HBA SAN cards in my RHEL5 server, and have heard that dual-path in RHEL5 is "included".  We have a Hitachi SAN, so I'm aiming for HDLM functionality (which is effectively dual-path).  Both HBA cards are online and working.  Is there a way that I can verify dual-path is working, without unplugging one of my fiber connections?

Thanks,
Mike.
