Preparing The Old Node For Removal - Hitachi NAS Platform 4000 Series Hardware Reference Manual

Procedure
1. Obtain the HNAS Factory Reset code for the required level to be installed on the
node.
2. Complete a factory reset of the new node per the documented procedure in order
to install the node at the desired code level.
3. Run nas-preconfig on the node, entering the required information to allow BALI
to start following a reboot of the new node.
For the Admin EVS, enter a valid IP address that is available for use temporarily.
Once this node is joined to the cluster this address will be removed and the existing
Admin IP address in the cluster will be used.

BALI.
