SolidFire HCI vSphere RDM configuration with LUN ID's
2019-09-19 06:08 AM
My lun's from the SolidFire storage are assigned LUN ID 0 in vSphere using iSCSI.
When using RDM's to create disks for a SQL cluster, the RDM's cannot be added to the second node.
Error:Incompatible device backing specified for device ‘0
Is there a way to make this work?

I haven't worked with SolidFire but looks like it's a well known error on the VMware blogs.
Some pointers :
1) While adding hard disk to additional nodes of cluster, instead of selecting Existing Hard Disk under New device drop-down menu, select RDM Disk under New device drop-down menu and click Add.
2) Select the LUN naaid which was added to the first node of the cluster. The LUN number may be different on this host.
3) Verify that disk got added successfully.
