RE: HMC controlling two sites.

Can the HMC work across a WAN?  I was once told that it had to be on
it's own separate LAN but I think I can make the HMC and FSP participate
in our LAN but I did not see where to put a default gateway for routing
and I do not know how much traffic goes between the HMC and iSeries.
Also I have two network cards on the HMC, on is on our LAN for remote
access and to call home to IBM, which it does well.  (Really nice when
the heat sink separated from the processor and fried the main board in
the 520.  While we were trying to figure out what happened, IBM called
us, Very Nice.

Subject: HMC controlling two sites.

Really time to change the subject Chris.

We have two HMC's.  And we have a 520 and a 570.  I almost never use the
second HMC.  I control both racks from the one HMC.  I just use the
second HMC to make sure I can do the same from it.  We've had this
working for awhile now.  Had some issues with we installed the freaking
joke of "redundant fsp's" where IBM sorta messed our HMC's up.  But it's
working ok now.  I have full confidence that when we move the one hmc
and the 520 off site we will continue to be able to do so.

How to configure is a different matter.  Both HMC's, and racks, go into
the switch.  They are not connected directly to each other.  After that,
it should be as easy as "discover systems".
