That was already the case (IP of mgt1 and IP of mgt[2] are the forwarders).
I don't believe it will forward requests within the zones that it is
authoritative.
I ended up using tabdump to recreate the hosts and nodelist tables. Mostly good.
Now the problem of the day is fixing the SSH credentials so that all the
diskless nodes booting off the
new frontend can get root access to all the nodes still booted off the old
frontend. Need this
especially for GPFS. I've been trying to follow what's going on in the
remoteshell postscript,
and I'm wondering if my "sitespecific" postscript is running before
"remoteshell" is competed.
Is there a way to determine/force the order the postscripts are executed?
Sitespecific is after
remoteshell both in alphabet and in the lsdef output.
The basic problem is that mmsdrrestore fails during sitespecific, but works
fine when I try it again later by hand.
