Flushing export policy caches
Flushing export policy caches manually (vserver export-policy cache flush) removes potentially outdated information and forces ONTAP to retrieve current information from the appropriate external resources. This can help resolve a variety of issues related to client access to NFS exports.
About this task
Export policy cache information might be outdated due to the following reasons:
A recent change to export policy rules
A recent change to host name records in name servers
A recent change to netgroup entries in name servers
Recovering from a network outage that prevented netgroups from being fully loaded
- If you do not have name service cache enabled, perform one of the following actions in advance privilege mode:

You should only flush the netgroup cache if you are trying to resolve a client access issue that is caused by a stale netgroup.
