Error : HACMP

[biondo68]

Hi,
In the Clverify Log find this error:

ERROR: Network option "tcp_pmtu_discover" has different settings between nodes
"it0001aix02" and "it0001aix01". Please make sure that the command no -o "tcp_pm
tu_discover" provides the same output on all cluster nodes.

ERROR: Network option "udp_pmtu_discover" has different settings between nodes
"it0001aix02" and "it0001aix01". Please make sure that the command no -o "udp_pm
tu_discover" provides the same output on all cluster nodes.

I checked the network tuning parameters and are different between two nodes

Node 1

udp_pmtu_discover = 1
tcp_pmtu_discover = 1

Node 2

udp_pmtu_discover = 0
tcp_pmtu_discover = 0

I don't remember which is the correct settings ?

Can I make the changes with the cluster active ?

Help me , please

Thanks

Have a look at this:

http://publib.boulder.ibm.com/infocenter/cmgmt/v8r3m0/index.jsp?topic=/com.ibm.vc.doc/smc00032.htm

For the cluster that i have they are set to 1!!!

So all you need is to change them on Node 2 to 1 and run the cluster verification to update the changes from Node 2!

I think you can do this while the cluster is up!

by the way, when you start a new thred try to choose the ? option instead of the lamp as this is used to indicate tips and not questions!

No offense. I'm just used to access the tips for information and i'm sure you would get more help by using the ? option
