Thank you.

Re: How to add a node on ServiceGuard Extension For RAC
Here is a summary of what must be done.
1) Insure the same version of Serviceguard is installed on the new server.
2) Insure the same number of heartbeat LANs are configured on the new server.
3) If LVM is used, create map files (vgexport -pvs -m ...) of shared VGs on a cluster node, and copy them to the server that you want to add to the cluster.
4) Import the VGs onto the new server. mkdir /dev/
mknod /dev//group c 64 0xNNNN (where NN = unique minor number)
vgimport -vs -m /dev/ )
5) Create a cluster configuration file that includes both the old cluster nodes and custom settings, with the new node.
# cmquerycl -c -C -n
Review the file, and if it looks good, apply it:
# cmapplyconf -f -C
The node is now a member of the cluster
To start SG daemons on it:
# cmrunnode

Re: How to add a node on ServiceGuard Extension For RAC
Thanks Stephen,
But my problem is :

(ServiceGuard Extension for RAC with CVM/CFS).
I don't know if i can add the new node like a standard cluster MC/Service Guard.
I don't how to export and import the CVM/CFS configuration on the new node ?
Help !!!
