I just noticed that there’s a new version(4.3) of the NetApp on NFS best practices document online. This document has a new best practice in there that I discussed a couple of weeks ago about the “/NFS/LockDisable” and the “prefvmx.consolidateDeleteNFSLocks” settings(Page 14).
As far as I can judge at this point in time the document seems to be also following the VMware guidelines. NetApp suggests running several commands directly on the Service Console to do the desired changes. Although I do agree with their suggested changes, I don’t agree with the order of the procedure.
On page 14 in both “procedures” NetApp suggests that you enter maintenance mode before applying the changes. Which is definitely something I would also suggest. But they also suggest to exit maintenance mode right before you reboot the server. In theory this could lead to VM’s being VMotioned to the host you’re about to reboot. When this happens the VM’s will be killed without any notice, which could lead to all sorts of problems as you can imagine.
So if you’re about to make the changes NetApp suggests, please change the order and do a reboot first and exit maintenance mode when the reboot is completed.
