+| **Plugin Title** | Disk MultiAz |
+| **Cloud** | GOOGLE |
+| **Category** | Compute |
+| **Description** |Ensure that Compute disks have regional disk replication feature enabled for high availability.|
+| **More Info** | Enabling regional disk replication will allow you to force attach a regional persistent disk to another VM instance in a different zone in the same region in case of a zonal outage. |
+| **GOOGLE Link** | https://cloud.google.com/compute/docs/disks/high-availability-regional-persistent-disk |
+| **Recommended Action** | Ensure that all Google compute disks have replica zones configured. |
+
+## Detailed Remediation Steps
+You must first create the regional Persistent Disk and then attach it to an existing instance. You can't create regional Persistent Disks as boot disks because they can't be force-attached during a failover.
+
+Create a regional Persistent Disk using the following steps:
+
+1.  In the Google Cloud console, go to the Disks page.
+
+    [Go to Disks](https://console.cloud.google.com/compute/disks)
+
+2.  Select the required project.
+
+3.  Click Create disk.
+
+4.  Specify a Name for your disk.
+
+5.  Select the Region and Zone. You must select the same region when you create your VM.
+
+6.  Select the Enable regional disk replication box.
+
+7.  Select the Replicate zone. Make a note of the zones that you select because you must attach the disk to your VM in one of those zones.
+
+8.  Select the Disk source type.
+
+9.  Select the Disk type.
+
+10. Click Create to finish creating your disk.
+
+11. After you create your regional Persistent Disk, [attach it to your instance](https://cloud.google.com/compute/docs/disks/add-persistent-disk#create_disk).
+
+    When attaching a disk to a VM, if the disk is already attached to another VM, you can force-attach the disk to the VM by selecting the Force-attach disk box on the Attach existing disk page. For more information on use cases for force-attaching regional Persistent Disks, see [Regional Persistent Disk failover](https://cloud.google.com/compute/docs/disks/repd-failover).
