Hi all,

         I am having one cluster active passive cluster.We are having HANFS also.One fs is exported from this cluster server to another client server. Now I want to remove this NFS from the client.And the same FS need to be mounted to another client server to access the HANFS FS.How can I achieve the same.What are the steps inviolved.Is there any downtime required.

OS-HP-UX11.31

Hey;

The steps to do that are the same as if you didnt' have a cluster with one addendum.  You can do that all in one command via:

exportfs -o access=${new_client} ${mount_point} # if 11.23/below or 

share -F nfs -o sec=sys,root=${new_client} ${mount_point} # for 11.31

The one addendum is that you'll want to update your hanfs script and copy it over to the adoptive node.  At some point, sooner rather than later, you'll want to run a failover test to verify that you haven't messed up the script at all.

Hope that helps.

Have you considered using HA-NFS templates provided in the HA-NFS toolkit? The manual describes how to implement HANFS in a Serviceguard environment. See http://www.hp.com/go/hpux-SG-NFS-docs -> Serviceguard NFS Toolkit A.11.11.06, A.11.23.05 and A.11.31.08 Administrator's Guide (May 2011)
