vsim 9.7 and 9.9.1 cluster perr partial

adminqskills

Hi everybody,

we do have the problem that we are unable to build a relationship between two, 2-Node vsim cluster.

We are only get

sim19c51::> cluster peer show
Peer Cluster Name Cluster Serial Number Availability Authentication
------------------------- --------------------- -------------- --------------
sim19c50 1-80-000011 Partial ok

I made ipspaces, broadcast domains mit mtu 1500 as well as 9000 but still no luck.

we made the cluster peer command with both ICL IP and only one ICL IP

cluster peer create -address-family ipv4 -peer-addrs 10.19.50.110,10.19.50.111 -ipspace intercluster

but still show partial

has anyone an idea what is wrong or missing?

thanks in advance for the answers

Yes, duplicate Serialnumbers will not work.

I am not sure how it suppose to show on a simulator. But, could you quickly go through the checks to ensure everything is setup ok.

thanks for the replies.

setup should done right, but cluster peer ping says ok , health not

Just for an experiment , I tried to create a cluster peer between my two Simulators 9.1 & 9.7, and it worked. That means there must be some communication issue between the two clusters in your case. I have attached the screenshot just for reference purpose. Please note, my setup is very simple, everything runs in the default ipspace. In my example - 9.1 is a single node cluster simulator and 9.7 is a two node cluster simulator.

adminqskills

is it possible that duplicate serialnnumbers are the reason? I can peer two single node cluster.

This is what i get in the log:

Yes, duplicate Serialnumbers will not work.

adminqskills

ok thanks for the information. But this behavior came with 9.7? With 9.6 we did not have these problem.

penangmis

Any idea how do we fix that, we recently upgrade one site of the box which have cluster peer to 9.9.1 and it now show same serial number for the other side (9.7) which was working before.

How do we fix this issue?
