Sun cluster 3.3 in guest LDOM - disable IPMP for public

871253Mar 12 2013 — edited Mar 14 2013
Hi,
i have setup HA-NFS with Sun cluster 3.3 in two guest LDOMs on two separate T4-2. The guest LDOMs get one VNET for interconnect and one VNET for public; the vswitch for public is 2x10g port aggregated on the control domain, so there is no need to have IPMP for public interface in the ldom. But sun cluster automatically does IPMP for public even with one vnet as failover however is it coming up as failed.

I have the exact same setup for another cluster in LDOMs and public interface IPMP with one vnet is working fine. Can't seem to get this one working. any tips?

vnet2: flags=19000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,NOFAILOVER,FAILED> mtu 1500 index 3

Basically, java wasn't designed to be that low level. Other than that, probably no good reason.

Yes, I see, but why isn´t it possible to write the header myself when it consists of usual bytes? That is what I can not understand.

At a guess it is because either (a) using raw sockets requires privileges and/or (b) Microsoft keep changing the raw sockets API or (c) it's a general-purpose programming language and why would you want to do that?

You can do raw sockets with third party libraries. They won't be pure java - but you didn't really expect to do raw sockets on your cell phone or TV set top box, or spy and spoof someone's network using an applet.

The FAQ for one such library hints what kind of a mess raw sockets are due to differences in common operating systems; see http://www.savarese.com/software/rocksaw/
At least to some extent the windows API didn't support raw access when java first came out.

So lowest common denominator would be a more likely explanation.
