cluster network error

[janine67]

Hello

wana to built a cluster with two node, but I have network error when I run cmcheckconf.
Lan4 on node prod1 cannot be configured in the cluster.
The lan4 is connected and correctly configured in the asci file.
Please take a look to the attached file and tell me what is wrong.

thanks

The error you have is:
lan4 on node test1 cannot be configured in the cluster
because it does not have an IP address, and it is not a standby lan for any ot.

"because it does not have an IP address"

Have you configured and ip to that NIC ?

can you post ifconfig output of both servers?

What is the use of configuring a NIC that doesn't have an IP and canot act as a standby LAN for any other NIC? It must either be assigned an IP that matches a subnet and NIC on the other node, or at least reside on the same network as another NIC that does have an IP (to be considered as a standby NIC).

hello
thanks for your reply.
If I want to set Lan4 as a standby lan for lan0, how can I set this in the asci config file.
I will provide you next the output of ifconfig lan4.
Best regards

you DONT set it in the ascii file.
Serviceguard must be able to do a physical check from lan0 to lan4 on the local AND the remote node at the time of doing the cmquerycl/cmapplycl
I.E. you should be able to use linkloop to check for physical connectivity between lan0 and lan4 on the local node, AND to the remote node.

lan4 should also NOT be configured at all, i.e. in netstat -in there should be no entry for lan4 on either node

Hello,
I think that the problem is on the lan4 connectivity. In this example is the LAN 4 standby for lan0 or lan2? Or it is for both?

NODE_NAME test1
NETWORK_INTERFACE lan2
HEARTBEAT_IP 10.10.5.5
NETWORK_INTERFACE lan0
STATIONARY_IP 10.10.100.4
NETWORK_INTERFACE lan4

I have added two others lan card, LAN1 and lan3, how can I set lan1 standby lan card for lan2 which is a heartbeat card and set LAN 3 and LAN 4 standby for LAN 2
thanks

neither, UNLESS there is physical connectivity between them.
Just having the lan card specified in the ascii file does NOT mean it is useable.
If you use cmquerycl and send the output to a file, i.e.create the ascii file, it will give you a comment BELOW the interface section indicating if a lan card may possibly be used as a standby.

To do this, cmquerycl does probing down all of the lans, and tries to see if there is PHYSICAL connectivity bertween a NIC that is configured with an IP and one that is NOT configured.
If all else fails, use linkloop or nwmgr to do physical link checks
