The PowerScale policy scan does not work with a Not All Nodes on Network (NANON) configuration, also known as Not Every Node on Network (NENON). This is because not every PowerScale node can connect to an ICAP server and this causes the anti-virus job engine to fail.
However, the PowerScale on-access scan can work with NANON. For more details, refer to the KB article OneFS: AVScan fails if one or more nodes are unable to connect to an ICAP server.
