HACMP and Filesystems question
Hello all. Yes, I searched the forum first 
I have hacmp running on 2 nodes. I wish to add a filesystem to the primary node to and existing shared VG. Not sure how to do this in a cluster environment.
My scenario:
Create the fs in the hacmp screens in smit add in the fs to and existing vg
My vg has 139GB so space is not an issue, I am looking to add a small (10gb) filesystem.
What I am not sure of is how to make sure this is picked up on the secondary node if there is a failover. Will this be done automatically, or do I need to do something specific?
Is the above logic flawed?
As always, thanks for any and all assisance.

Hello,
I was wondering if I have 3 nodes (A, B, C) all configured to startup with HACMP, but I would like to configure HACMP in such a way:
1) Node B should startup first. After the cluster successfully starts up and mounts all the filesystems, then
2) Node A, and Node C should startup !

Hi Guys,
is it possible to failover a hacmp cluster in one datacentre via SRDF to a single node in another datacentre, or do I need a cluster there in any case? This is only meant as worst case scenario and my company doesn't want to spend more money than absolutely necessary.

Hi all,
I am new to HACMP. So sorry for the newie question. But I did search the forum and it seems that no one asks this before.

If it runs in active-stanby, it is easy to... (9 Replies)

cmrunnode
cmrunnode(1m) cmrunnode(1m) NAME
cmrunnode - run a node in a high availability cluster SYNOPSIS
cmrunnode [-v] [node_name...] [-t | -w none] DESCRIPTION
cmrunnode causes a node to start its cluster daemon to join the existing cluster. This command verifies the network configuration before causing the node to start its cluster daemon. To start a cluster on one of its nodes, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the clus- ter configuration file. See access policy in cmquerycl(1m). Starting a node will not cause any active packages to be moved to the new node. However, if a package is DOWN, has its switching enabled, and is able to run on the new node, that package will automatically run there. If node_name is not specified, the cluster daemon will be started on the local node and will join the existing cluster. Options cmrunnode supports the following options: -v Verbose output will be displayed. -t Test only. Provide an assessment of the package placement without affecting the current state of the nodes or packages. The -w option is not required with the -t option as -t does not validate network connectivity, but assumes that all the nodes can meet any external dependencies such as EMS resources, package subnets, and storage. node_name... Start the cluster daemon on the specified node(s). -w none By default network probing is performed to check that the network connectivity is the same as when the cluster was configured. Any anomalies are reported before the cluster daemons are started. The -w none option disables this probing. The option should only be used if this network configuration is known to be correct from a recent check. RETURN VALUE
cmrunnode returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Run the cluster daemon on the current node: cmrunnode Run the cluster daemons on node1 and node2: cmrunnode node1 node2 AUTHOR
