Goal


Is it expected to see the active (OWNER) head reboot when the "takeover" command is run from the passive (STRIPPED) head ?

Below is the description for the TAKEOVER option available in the Oracle ZFS Storage Appliance (online) Help Guide available in the BUI:


 


BUI

The Configuration->Cluster view provides a graphical overview of the status of the cluster card, the cluster head node states, and all of the resources.

Description




Setup
If the cluster is not yet configured, execute the cluster setup guided task, and then return to the current screen. See above for a detailed description of this task.




Unconfig
Upgrade a node to standalone operation by unconfiguring the cluster. See below for a detailed description of this task.




Apply
If resource modifications are pending (rows highlighted in yellow), commit those changes to the cluster.




Revert
If resource modifications are pending (rows highlighted in yellow), revert those changes and show the current cluster configuration.




Failback
If the current appliance (left-hand side) is the OWNER, fail-back resources owned by the other appliance to it, leaving both nodes in the CLUSTERED state (active/active).




Takeover
If the current appliance (left-hand side) is either CLUSTERED or STRIPPED, force the other appliance to reboot, and take-over its resources, making the current appliance the OWNER
