TECH::Partial Givebacks during Storage Failovers in NetApp’s Clustered Data ONTAP

If you’ve ever used clustered Data ONTAP and done storage failover tests, you may have noticed something strange when you attempted a giveback.

cluster::> storage failover giveback -ofnode node1
Info: Run the storage failover show-giveback command to check giveback status.

cluster::> storage failover show
                              Takeover 
Node           Partner        Possible State Description

Partial Givebacks (No takebacks)

So, what happened?

To better understand that, we need to understand how storage failovers work in clustered Data ONTAP and how they differ from storage failovers in 7-Mode. Find out more on the complete post on DataCenterDude.com!
