Re: back to back cluster
1. Load the required licenses on both machines (don't forget the CLUSTER license)
2. Make the physical connection.
3. Run the CLUSTER$CONFIG procedure on one machine. Here, you CREATE the cluster, giving it a name, number and password.
4. Reboot machine # 1
5. Run the CLUSTER$CONFIG procedure on the other machine and JOIN the cluster. Here, you specify number and password of the cluster to join.
6. Reboot machine # 2
and you're done.
And since it's VMS (well designed) there is no need for DECNet nor TCPIP (Cluster communication uses a separate protocol).
There are quite a number of things to consider if you want to take advantage of all facilities a VMS cluster offers (there is a whole manual about cluster configurations), but this is the base of all. Once it took me about 15 minutes ;-)

Re: back to back cluster
Considering the time it takes some managed ethernet switches to boot, having a direct ethernet connection for LAVC can make the cluster more robust. The machines shouldn't have any problem finding themselves over the dedicated link.

Re: back to back cluster
right now the cluster is assembled and runing, but its only lan cluster.
If I wan connect back to back for hardbit I need rebuild again with cluster_configure?
Thanks for your comments

Re: back to back cluster
so, you HAVE an existing cluster:
- Shutdown
- do the physical instal
- reboot
The cluster will automagically use all available interconnects.
(if you would venture and succeed in installing the new connection in the RUNNING cluster, even the reboot would not be necessary! )
Proost.
Have one on me.

Re: back to back cluster
Are the nodes connected to a network switch/hub/other and you plan to replace this with a simple cable?

Re: back to back cluster
If I understand yours situation, you have two configured cluster nodes in lan cluster. Each node has two or more lan adapters. One of these adapters on each node is free (not connected).
If this is correct just connect the cross cable betwen the adapters and you are done. The connection will be detected automaticaly.

Re: back to back cluster
Edgar,
Bojan is correct, if you have open network ports you just need to connect them. The cluster will automatically begin to use the new path for SCS (cluster) traffic.
You do need to make sure the ports are both configured for the same speed and duplex settings. You can use the LANCP utility for this.
$ MCR LANCP SHOW DEVICE
$ MCR LANCP SET DEVICE EIB0/SPEED=100/FULL_DUPLEX
$ MCR LANCP DEFINE DEVICE EIB0/SPEED=100/FULL_DUPLEX
Note for your networking team, you don't want a second VLAN on the same hardware the primary network interfaces are connected to. This is a redundant path to ensure cluster availability. For two nodes a cross over cable will do the job. For more than two nodes, you need to have a redundant network connection, either a switch or hub.
