Volumes support ability to boot an Operating System over iSCSI for physical servers. In this configuration, a host can start a supported Operating System from a LUN instead of a Local Disk instance.

This procedure describes how to configure Network Adapter BIOS Settings to enable this feature.

Important Points:

• Refer to Intel Ethernet Adapter Vendor Documentation for more details about  Intel iSCSI Boot Configuration.
• According to Intel, we might be able to configure these settings through Adapter's Properties > Data Options Tab in Microsoft Windows Device Manager.
• Check Volumes Requirements and Supported Clients for a list of the supported network hardware and clients.
• Refer to Enable Nutanix Volumes and read about the procedures to perform on the Nutanix cluster. Before performing an iSCSI target discovery of the Nutanix cluster, configure BIOS boot settings for the network adapter as described in these steps
