The same result can be accomplished by using the command cf disable followed by the
halt command.
From the CFE prompt or the boot LOADER prompt, depending on the model, the system can
be rebooted by using the boot_ontap command.

7.4.3 Basic HA pair configuration management

This section demonstrates HA pair configuration management, including forced HA pair
takeover and giveback.
Attention: Taking over resources affects the client environment. In particular, Windows
users and shares (CIFS services) are affected by this procedure.
Issue the cf takeover command on the node that will remain operating and take over
resources of the other node. In the example, take the node itsosj_n2 offline by issuing cf
takeover on node itsosj_n1.
Initiating takeover by using the CLI
Use the following steps if working from a command line:
1. Check the HA pair status with the cf status command as shown in Example 7-9.
Example 7-9 cf status: Check status
itsonas2> cf status
Cluster enabled, itsonas1 is up.
itsonas2>
2. Issue the cf takeover command. Example 7-10 shows the console output during
takeover.
Example 7-10 cf takeover command
itsonas2> cf takeover
cf: takeover initiated by operator
itsonas2> Sat Apr 9 02:00:22 GMT-7 [itsonas2: cf.misc.operatorTakeover:warning]: Cluster
monitor: takeover initiated by operator
