NFS export during DR scenario

NFS export during DR scenario


One of the interface system exporting(NFS) the directory to the production Server's DNS name (say prod.aa.com which points to production IP address) and NFS mounted on that Server. In case of Disaster Recovery, I failover the applications to the DR Server and I am making changes on the DNS server to resolve DR Server IP address to prod.aa.com. In this scenario, can I just NFS mount the directory on the DR Server which I have exported before to the old prod. server? or Do the NFS export again to the new server from the source system?

Re: NFS export during DR scenario

First of all your DR Server must be nfs compatible. if it is a HP-UX OS, of course there is no problem at all.
But you need setup for this nfs mount; go through the steps:

setup /etc/rc.config.d/ ; change from 0 to 1

/sbin/init.d/nfs.server start

setup /etc/exports ; enter /nfs/your_created_directory_for_nfs

# exportfs â v /nfs/your_created_directory_for_nfs
