No. This is entirely client side behavior. NFS server has no way to know whether client caches anything or not.

Subject: Query Netapp for NFS client mount options?

I'd like to know which NFS clients are mounted with the noac option.

Can I query OnTap 8.1RC2 for this info? If so, how?

thanks,

Fletcher.
