Для тех, кто использует NetApp Storage Encryption with KIMP servers и собирается апдэйтить ONTAP:
"We upgraded to 9.7P5 and we had an issue with losing connectivity to the external key manager server.
The server config file (on each node) was wiped upon boot up.
Volumes went offline due to the keys not being retrievable from the EKM due to the server config file being wiped, and the node not knowing how to communicate with the EKM server."
На что НетАпп советует:
Key Management Interoperability Protocol (KMIP) server connections must be reconfigured after upgrading to ONTAP 9.3 or later. If you upgrade to ONTAP 9.3 or later on a system that uses NetApp Storage Encryption with a KMIP server, after the upgrade, you must delete the existing KMIP server connection and establish ones. You can use the delete-kmip-config command to delete the existing KMIP server connections.
