Software iSCSI setup on ESXi

How to set up the Software iSCSI initiator in ESXi

Go to the Inventory  Hosts and Clusters  Configuration  Storage Adapters screen

iSCSI-Adapter

Click the iSCSI Software Adapter, if it’s not present simply click the Add button on the top right of the screen to add the iSCSI Software Adapter.

iSCSI-None

As you can see here that no paths have been configured, click the Properties button from the lower pane to bring up the iSCSI Initiator properties.

iSCSI-Prop

Click Network Configuration

iSCS-Init-blank

Now we need to add the Port Groups, Click Add

iSCSI-vSwitch

Add each required port group individually.

We now have 1 port groups added to the iSCSI Initiator, click the Dynamic Discovery tab

iSCSI-Dy

Add the IP or Host name for your iSCSI storage, click on the Static Discovery tab. Click Close

iSCSI-rescan

Click Yes

iSCSI-devices

We now have four paths to the iSCSI Storage server but we would only be using a single path back to our storage so we need to change our Path Selection setting from MRU (Most Recently Used) to Round Robin.

iSCSI-mgmt-Path

Right click the LUN and choose Manage Paths…

iSCSI-fixed

Change the Path Selection to Round Robin.

iSCSI-fixed

Changing to Round Robin has made all the Paths Active and all of them are now being used to issue I/O to the LUN.

Repeat these steps on all hosts.

Once you have completed these step you iSCSI should be ready to present the LUNs/DataStores.
