If you are able to copy audit logs from the failed primary Admin Node, you should preserve them to maintain the grid's record of system activity and usage. You can restore the preserved audit logs to the recovery primary Admin Node after it is up and running.
This procedure copies the audit log files from the failed Admin Node to a temporary location on a separate grid node. These preserved audit logs can then be copied to the replacement Admin Node. Audit logs are not automatically copied to the new Admin Node.
Depending on the failure of the Admin Node, it might not be possible to copy audit logs from the failed Admin Node. In a deployment with more than one Admin Node, audit logs are replicated to all Admin Nodes. Thus, in a multi‐Admin Node deployment, if audit logs cannot be copied off of the failed Admin Node, audit logs can be recovered from another Admin Node in the system. In a deployment with only one Admin Node, where the audit log cannot be copied off of the failed Admin Node, the recovered Admin Node starts recording events to the audit log in a new empty file and previously recorded data is lost.
