A trainee system administrator has been tasked with expanding an existing vRealize Operations Manager cluster...

The generate passphrase option allows the vRealize Operations administrator to create a one-time passphrase that can be used instead of the administrator credentials to add a node to the cluster. This option is useful when the administrator wants to delegate the task of adding a node to another user without exposing the administrator password. The passphrase is valid for 24 hours and can be used only once. The trainee administrator can use the passphrase to authenticate into the vRealize Operations Manager administration interface and then select the Expand an Existing Installation option to add a new node intothe cluster1. References: 1: Expand an Existing Installation to Add a Data Node
