    More info:

    After going through Symatec docs, I've now changed the config as follows and now on a "hastart" post a  "hastop -all -force", the share goes offline and almost after a minute, VCS restarts the NFS resource and then the Share resource. While the situation is better I still have a 1minute outage.

    Also, is NFSRestart a requirement if so, preonline requirements a must as well. I don't see NFSRestart adding any value if Lock failover is not enabled.

    This could be 5.1 version issue as I don't seem to hit this issue with 5.1Sp1
