In OneFS release 9.5.0.0 and later IPv6 is disabled by default for new clusters, unless IPv6 is configured during the initial cluster configuration wizard. For existing clusters that upgrade to OneFS release 9.5.0.0, the current IPv6 configuration remains intact. In OneFS release 9.5.0.0 and later, once IPv6 is enabled on a new cluster, the IPv6 sub-options must also be enabled manually. IPv6 options are configured using the isi network external commands.
