No Disks Suitable For Cluster Disks Were Found

Question

I would like to preface this with the fact that I had success in performing the process below on a Windows Server 2012 R2 cluster with no issues.

We are currently in the process of geoclustering ( I know, it's an old term ) a few of our SQL clusters for a DR type scenario.

Setup:

Four node cluster running Server 2019.
Three nodes in a datacenter in Atlanta.
Storage attached to the three nodes from an appliance in Atlanta.
One node in a datacenter in Dallas.
Storage attached to the single node from an appliance in Dallas.

When trying to add the attached storage from the single node, failover cluster manager states there are no disks available.

I have tried removing/re-adding the storage and removing/re-adding the single node from the cluster in different orders with the same result.

Is there something different between Server 2019 and Server 2012 that would prevent it from recognizing the attached storage on the single node?

Hi @Anonymous

Thank you for your question and reaching out.

1. Please check if the Disk are already part of any another cluster?
2. Please check if you can see the disks in disk management? have you got the disks online or offline?
3. Please make sure that the Cluster validation shows all iSCSI drives as valid.
4. Run below PowerShell to clear Disk reservation ( Change disk number as per in Disk Management)
   “Clear-ClusterDiskReservation –Disk 4”
5. Please configure the volumes at the iSCSI initiator on each node. and also make them to ‘Auto-configure’ .

Hope this answers your question :)
Thank you.
