Takeover not possible: NVRAM log not synchronized
Applies to
- NetApp Storage systems with external HA interconnect cables
- More information at HA interconnect procedure guide for ASA, AFF and FAS platforms
- Except MetroCluster IP solutions
Issue
- Check Active IQ if this impacts your systems
- Manual
storage failover showcheck reports. Example:
cluster1::> storage failover show TakeoverNode Partner Possible State Description-------------- -------------- -------- -------------------------------------cluster1-01 cluster1-02 true Connected to cluster1-02cluster1-02 cluster1-01 false Connected to cluster1-01, Takeover is not possible: NVRAM log not synchronized2 entries were displayed.
- Displaying the "
Reason Takeover not Possible" field shows the following. Example:
cluster1::> storage failover show -fields reason
node reason
-------------- ------
cluster1-01 -
cluster1-02 "NVRAM log not synchronized"
- Manual takeover is not possible. Example:
cluster1::> storage failover show -node cluster1-n1 -fields possible
node possible
------------ --------
cluster1-01 false
- In Fabric MetroCluster environments the following check output can be reported. Example:
cluster1::> metrocluster check node show -instance Node Name: cluster1-01 Type of Check: ha-mirroring-op-state Cluster Name: cluster 1 Result of the Check: warningAdditional Information/Recovery Steps: Node's HA mirroring is not online. Verify the HA mirroring link status with the "metrocluster interconnect show" command, then bring the HA mirroring online with the "storage failover modify -node <node> -enabled true" command.
- ONTAP Event Message System (EMS) is reporting. Example:
... [cluster1-01: statd: cf.takeover.disabled:alert]: HA mode, but takeover of partner is disabled due to reason : unsynchronized log.
