iSCSI configuration for ESXi using VSC overview

Contributors netapp-ahibbard NetAppZacharyWambold

This content describes how to quickly set up the iSCSI service on a storage virtual machine (SVM), provision a LUN, and make the LUN available using an iSCSI initiator on an ESXi host computer.

This content is based on the following assumptions:

  • You want to use best practices, not explore every available option.

  • You do not want to read a lot of conceptual background.

  • You want to use System Manager, not the ONTAP command-line interface or an automated scripting tool.

  • You want to use the Classic System Manager UI for ONTAP 9.7 and earlier releases, not the ONTAP System Manager UI for ONTAP 9.7 and later.

  • You are using the native ESXi iSCSI software initiator on ESXi 5.x.

  • You are not using CHAP authentication for iSCSI.

  • You are using a supported version of Virtual Storage Console for VMware vSphere to configure storage settings for your ESX host.

  • Your network uses IPv4 addressing.

  • You want to assign addresses to logical interfaces using any of the following methods:

    • Automatically from a subnet you define

    • Manually, using an address selected from an existing subnet

    • Manually, using an address that will be added to an existing subnet

  • You have at least two high-speed Ethernet ports (1 GbE minimum, 10 GbE recommended) available on each node in the cluster.

    Onboard UTA2 (also called CNA) ports are configurable. You configure those ports in the ONTAP CLI; that process is not covered in this content.

    You should see ONTAP 9 Network Management for using the CLI to configure Ethernet port flow control.

  • You are not configuring iSCSI SAN boot.

  • You are providing storage to VMs through the ESXi hypervisor and not running an iSCSI initiator within the VM.

If these assumptions are not correct for your situation, you should see the following resources:
