How to add a node on ServiceGuard Extension For RAC

[David Dilly]

Hello,
I look for information on how I can make to add a new node in a MC/Service Guard cluster using CVM/CFS.

Thank you.

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

Thanks Stephen,

But my problem is :
there is not LVM between the two nodes its CVM/CFS, it's for an Oracle RAC.
(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 !!!
