How to Setup Azure Shared Storage

This section explains how to create a new virtual machine (VM) on a shared disk and attach it. If using an existing VM, proceed to step 3, “Create and attach a new disk”, and attach it to the existing VM in step 4. This will allow you to edit the existing VM instead of adding a new VM. “SCSI-3 Persistent Reservations (SCSI3) Recovery Kit” is needed for the step 7. Add the Recovery Kit by updating the installer if needed.

1. Create Storage Account
   1. Create a new resource group

2. Create a VM in the Resource group: ShareStorageSLES

3. Create a new disk that is shared by selecting Create and attach a new disk.

Select “Enable shared disk” and specify max shares. This will be a 2-node cluster, only 2 max shares are needed.

4. Create a second VM in the same resource group in the same zone. Instead of selecting “Create and attach a new disk” select “Attach an existing disk”.

!Important: Confirm that “None” is selected in the Host caching. The default, “Read-Only” has been selected.

Select the disk created in step 3.

5. Login to the primary node (“test-cluster-sles15-1”) via SSH, then format the disk.

6. Download/transfer LifeKeeper and the temporary license keys.

7. Install LifeKeeper
   1. Notice the SCSI3 Recovery Kit is automatically selected.

8. Setup communication paths.

9. Partition the shared disk on the test-cluster-sles15-1.

a. Cause the test-cluster-sles15-2 to update the partition table.

10. Create a file system on the partition.

11. Create file system resource.

12. Extend to the second node.

13. Done
