We have 2 servers using Windows Server 2019 in a Cluster (Server3 and Server4). I've used iSCSI to connect to a Dell Powervault MD3220i storage array

In Dell Modular Disk Storage Manager I have created several Virtual Disks and assigned them to a Host Group containing both servers. I then configured iSCSI on both servers

When I go onto either server and access "Server Manager - File and Storage Services - Volumes - Disks" I can see see both Server3 and Server4; and when I expand them I can see the & virtual disks beneath the local disks.

I am able select any virtual disk, initialize as GPT Partitions and create New Volume as either a drive letter or folder.

However, every time I right-click on a disk beneath Server4 and "Bring Online" the letter/folder will come online on Server3

e.g. If I create volume for S: drive, and i bring it online under either Server3 or Server4, the S: drive will only ever appear on Server3

NB. I have other virtual disks in the same host group that I use in SQL & CSV cluster nodes and they run on either server.

Any advice
