NFS client reports error when server is brought down using shutdown command

On Solaris 11, when the VCS cluster node having the NFS share service group is brought down using shutdown command, NFS clients may report "Stale NFS file handle" error. During shutdown, the SMF service svc:/network/shares un-shares all the shared paths before taking down the virtual IP. Thus, the NFS clients accessing this path get stale file handle error.

Workaround: Before you shutdown the VCS cluster node, disable the svc:/network/shares SMF service, so that only VCS controls the un-sharing of the shared paths during the shutdown operation.
