Issue

In clusters running ONTAP 9.6 or 9.7, cluster peer errors are generated at random times:

[node-01: mgwd: cpeer.xcm.update.warn:error]: Periodic update of peer network information failed. The following operations are incomplete: discovery failure.

[node-01: mgwd: cpeer.xcm.addr.disc.warn:error]: Address discovery failed for peer cluster 15897456-d9fg-11e7-9c45-xfghdfgsgheds. Reason: Failed to discover remote addresses: Timeout: Operation "clusterPeer_rtable_iterator::get_imp()" took longer than 60 seconds to complete [from mgwd on node "node-01" (VSID: -3) to mgwd at 15897456-d9fg-11e7-9c45-xfghdfgsgheds].

[node-01: mgwd: cpeer.ping.no.lifs:error]: Failed to find intercluster LIFs in IPspace Default on node node-01.

[node-01: mgwd: cpeer.xcm.update.warn:error]: Periodic update of peer information from CLUSTERNAME failed. The following operations are incomplete: The identity of peer cluster 15897456-d9fg-11e7-9c45-xfghdfgsgheds not found.

This may lead to vifmgr and mgwd restart on the node causing the data LIFs to migrate.
If failover targets are not configured properly, this may lead to a data outage.
