Data ONTAP Discussions

Re: MetroCluster & NVRAM Interconnnect

If interconnect is broken because of controller failure, partner will take over.

If interconnect fails first and controller fails later, takeover does not happen, because NVRAM cannot be synchronized so there is no way for a partner to replay it.

As soon as interconnect fails you will see message “takeover disabled”.
