v
You must have a network interface to the HA pair partner node.
v You must have a separate IP address to use to netboot the target node.
About this task
The following procedure is written with the assumption that the target node has
been taken over by the partner node and that the target node has booted to the
boot environment prompt after the takeover has been completed.
Attention: You can only use this nondisruptive procedure in an HA pair that is
running Data ONTAP 8.1.1 and later.
Procedure
