How to perform Takeover/Giveback
Applies to
- ONTAP 9
- Storage Takeover/Giveback
Description
- This article covers performing a takeover and giveback of a node in an ONTAP cluster
- If one or more nodes in the cluster needs to be shutdown, instead follow Gracefully shutdown and power up your storage system Resolution Guide
Procedure
System Manager
- Use System Manager to Perform a Reboot of the node
- When the node reboots the HA partner automatically executes a takeover
- After the reboot is complete the giveback option can be performed through System Manager
ONTAP CLI
- Check that both nodes are connected with the storage failover show command:
cluster1::> storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Connected to cluster1-02
cluster1-02 cluster1-01 true Connected to cluster1-01
2 entries were displayed.
- If the
Possiblefield is false; enable storage failover before proceeding. - If automatic giveback is not desired after performing a takeover, review How variations of the storage failover modify command affect automatic giveback. During the takeover Data LIFS (logical interfaces) automatically migrate off the target node. If manual LIF migration is desired ahead of the takeover, use the network interface migrate-all command. None of the items in this step are required.
- Initiate a takeover of the node to be taken over:
cluster1::> storage failover takeover -ofnode <nodename>
The following example causes a node named cluster1-02 to be taken over
cluster1::> storage failover takeover -ofnode cluster1-02
Warning: A takeover will be initiated. Once the partner node reboots, a giveback will be automatically initiated. Do you want to continue? {y|n}: y
- Check the progress of the takeover:
cluster1::> storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Takeover scheduled. cluster1-02
has relocated its SFO aggregates in
preparation of takeover.
cluster1-02 cluster1-01 false Pending shutdown
2 entries were displayed.
- Check if the takeover is finished, and then giveback will perform automatically, or you can giveback manually:
cluster1::> storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 false In takeover, Auto giveback will be
initiated in 416 seconds
cluster1-02 cluster1-01 - Waiting for giveback
2 entries were displayed.
- If the giveback is not started automatically, then you can perform a manual giveback:
cluster1::> storage failover giveback -ofnode <nodename>
- Run the storage failover show to ensure that both nodes are connected:
cluster1::> storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Connected to cluster1-02
cluster1-02 cluster1-01 true Connected to cluster1-01
2 entries were displayed.
- After the giveback is complete, it may be necessary to Revert all LIFs back to their home port.
