Scripting /etc/fstab changes

[Danda, Richard SFC]

Greetings all,

I have a NetApp FAS270 filer that I have migrated NFS data directories too.
I need to make changes to all my RHEL machines to point to the new device
for mounts. Is there an easy way to script the change?

Example:

Current /etc/fstab

hostA:/user/bin  /user/bin  nfs  defaults 0 0
hostA:/user/lib   /user/lib	  nfs defaults 0 0
hostA:/home/common/storage   /home/common/storage  nfs  defaults 0 0

Need to change it to this:

hostB:/user/bin  /user/bin  nfs  defaults 0 0
hostB:/user/lib   /user/lib	  nfs defaults 0 0
hostB:/home/common/storage   /home/common/storage  nfs  defaults 0 0

I believe you can use sed or awk, to do that????

Thanks for any assistance.
