Error: Permission denied to 192.168.28.21

[Gregor Weertman Euramax]

After changing the subnet of a cluster I get "Error: Permission denied to 192.168.28.21" when executing cmviewcl.
the subnet is changed from 255.255.255.0 to 255.255.252.0.
The file cmclnodelist seems to be configured properly.
Wat can be the problem?

Shalom,

Both nodes of the cluster need to be in the same subnet.

Then:
cmquerycl
cmcheckconf
cmapplyconf

After any package scripts that include subnet are modified.

This is something that you should be able to pull off without downtime(rolling node by node change), though its easier to implement with a down cluster.

You should reconfigure the cluster for new changes. What is your SG version ?

See examples and hints for changing IP/netmask - http://docs.hp.com/en/B3936-90122/ch07s04.html#cegieecb

What is your default router address? Could it be a network issue or what address is being broadcast.

I'm no network person, but I believe that changing the subnet mask could affect what address actually gets broadcast, depending on your network configuration. And it is possible that some network router information may be affecting what that is.

I'll probably explain this badly-but I'll give it a shot...So all you real network gurus feel free to correct me...I welcome the training.

Let's say your default route is 192.168.28.1, with a subnet mask of 255.255.255.0 then you will broadcast as 192.168.28.0 - and that should be ok.
But if your now using a default router that is on a different subnet and now you've changed your subnet mask value to x.x.252.0 couldn't that change which subnet you are broadcasting on. Wouldn't it go to the lowest possible c class subnet that it can broadcast on and broadcast from there?

And by the way..when you made the network change in your cluster - did you make with the cluster up or down? Did you check/apply things?

I failed to do the cmapplyconf.
When I have the oppertunity I will shut the packages down change the subnet and applyconf.
I hope I can do it on saturday.
