Windows Server 2022 Failover Clustering iSCSI Target

Let’s have a look at Windows Server 2022 Failover Clustering iSCSI Target setup and configuration. The two-node failover cluster configuration operating Windows Server 2022 with shared disks mapped from the ISCSI san.

In this guide, I will cover the steps of the creation of a two-node Active/Passive Windows Server Failover Cluster. For the purpose of creating such a cluster it is necessary to have a few things in place, so I thought I should start from the beginning. This guide will brief connection to shared NAS storage using the iSCSI initiator.

I have experience involving in creating High Availability solutions for Enterprise products and based on that work have a short time ago worked with Windows Failover Clustering and network load balancing clustering in Windows Server 2022. I have built multi-node failover clusters for Hyper-V, SQL Server, different applications, and Network Load Balancing clusters.

Now you can see Failover Cluster Manager in Server manager tools

Server Manager Tools

Creating Windows Server cluster – Using iSCSI to connect to shared storage

Follow the below steps to configure iSCSI.

Run the iSCSI Initiator from the first Node Server 2022 (WS2022-01).

Click on tools and then iSCSI initiator

Server manager 2022

Select the Yes button to start the iSCSI initiator service and enable it to start automatically every time when a server reboots. You want this service to start automatically so that your cluster nodes will be automatically connected to the shared storage when rebooting.

Microsoft iSCSI service is not running

The iSCSI Initiator will popup, click on the Discovery tab.
Click the Discover Portal button.

iSCSI initiator properties discovery

Type the IP Address of the iSCSI shared storage and then click on the Advanced button.

Discover target portal

In the Advanced settings from the Local Adapter, the dropdown box chooses Microsoft iSCSI Initiator, and in the Initiator IP box choose the IP Address of the NIC that is dedicated to your iSCSI connection. Click ok twice

Discover target portal advanced settings

Choose the LUNs you need to connect to and then click the Connect button.

iSCSI initiator properties targets

Click ok

iSCSI initiator connect to target

Now you are connected to your iSCSI target.

Follow the same steps for the secondary node

How to create Windows cluster configuring shared disk in the cluster node 1 (WS2022-01)

We will have a look at configuring the disks we have attached to our prospective cluster nodes.
Type DISKMGMT.MSC in the run box and then hit enter to open disk management.

Diskmgment.msc run command

Now you can see the shared disk (iSCSI) displayed as Offline, Unknown, and Unallocated.
Right-click on the disk representation and then choose Online.

Disk management online disk

Right-click on the disk and then choose Initialize Disk.

Disk management initialize disk

Click ok

Initialize disk

Right-click on the disk and then choose New Simple Volume.

Disk management new simple volume

Click Next

Welcome to new simple volume

Click Next

New simple volume size

Assign the drive letter by selecting it from the dropdown menu. In this shared disk I am using E. Click Next

New simple volume drive letter

Provide a volume label and then click next.

New simple volume format partition

Select the Finish button to complete the creation of the volume.

Completing the simple volume wizard

Now you can see the shared disk.

Disk management

After configuring the disks on the first node, take them offline. Right-click on the disk and select Offline.

Disk management disk offline

On the second cluster node (WS2022-02) open disk management by typing DISKMGMT.MSC in run command.

Right click on the disk and then select Online.

Disk management disk online

The disk(s) appear and are formatted with the drive letter.
If the drive letter doesn’t show then select Rescan Disks from the Action menu.

Failover Cluster readiness check on Primary Node (WS2022-01)

Now we have successfully mapped two nic’s to both servers, and added the same ISCSI san on both servers, formatted and have a volume up on one server.

Let’s verify if everything is ok.

Under Server Manager choose Tools and then select Failover Cluster Manager.

Server manager

Under the Action menu, select Validate Configuration.
