Answer

  1. Ensure that all vservers and data lifs associated with these vservers have NFS protocol allowed
  2. To completely prevent the bug from happening you can clear the lmgr host list prior to reboot or takeover.

** Performing this step will cause all NFS3 clients to lose their lock state upon node reboot **

  1. set d -c off;systemshell -node < node | * > sudo kenv bootarg.lmgr.clearhostfile=1
  2. This command will force all of the entries in the host file to be removed next time the host file is read.
  3. This command will need to be ran on all nodes that will house NFS Lifs.
