Yes, there is. But before trying to administrate a HACMP-cluster you should really REALLY know what you are doing. This can end up in disaster pretty fast.

In the details of of the resource groups definition (the same SMIT panel where you also state the VGs which belong to it) you can also define NFS-mounts to be part of the RG. Note, that you will need some non-NFS file system for NFS-4 mounts. (Because, unlike NFS3, NFS4 is state-aware. Locked files stay locked.)

Notice also that for NFS4 to work you need different services started, not the same as for NFS3. You also need to configure the NFS-domain before, which i suggest to be the same as the DNS-domain of the system (as this is easier to manage).

I hope this helps.

NAME
nfsmount.conf - Configuration file for NFS mounts SYNOPSIS
Configuration file for NFS mounts that allows options to be set globally, per server or per mount point. DESCRIPTION
The configuration file is made up of multiple sections followed by variables associated with that section. A section is defined by a string enclosed by [ and ] branches. Variables are assignment statements that assign values to particular variables using the = operator, as in Proto=Tcp. Sections are broken up into three basic categories: Global options, Server options and Mount Point options. [ NFSMount_Global_Options ] - This statically named section defines all of the global mount options that can be applied to every NFS mount. [ Server "Server_Name" ] - This section defines all the mount options that should be used on mounts to a particular NFS server. The "Server_Name" strings needs to be surrounded by '"' and be an exact match of the server name used in the mount command. [ MountPoint "Mount_Point" ] - This section defines all the mount options that should be used on a particular mount point. The "Mount_Point" string needs to be surrounded by '"' and be an exact match of the mount point used in the mount command. EXAMPLES
These are some example lines of how sections and variables are defined in the configuration file. [ NFSMount_Global_Options ] Proto=Tcp The TCP protocol will be used on every NFS mount. [ Server "nfsserver.foo.com" ] rsize=32k wsize=32k A 33k (32768 bytes) block size will be used as the read and write size on all mounts to the 'nfsserver.foo.com' server. [ MountPoint "/export/home" ] Background=True All mounts to the '/export/home' export will be performed in the background (i.e. done asynchronously). FILES
