In this section, PowerFlex volumes are created and mapped to VxRail dynamic nodes cluster, using which a datastore will be created for running workload VMs.
Before you begin, ensure that:
The following figure shows the high-level overview which represents the volume mapping procedure:
To create the PowerFlex volume:
1. Log in to PowerFlex Presentation Server (PowerFlex GUI) using your MDM credentials and navigate to Volume tab.
2. Click ADD.
3. On the Add Volume page, enter the number of Volumes (if two or more number of volumes are to be created, add a volume prefix and starting number) and the Volume Name.
4. Select Thick or Thin provisioning and then specify the Volume Size.
Note: The PowerFlex volume size will always be a multiple of 8. The free capacity of the shared datastore for the VxRail system should be 800 GB at least.
5. Select Storage Pool from the list of pools.
6. Click ADD VOLUME.
To expose the PowerFlex volumes to the work domain nodes:
1. Select the volumes that you created and in the upper right corner, select MAPPING > Map.
2. Under SDCs, select all SDCs used for this configuration, and then click MAP and APPLY.
3. After the volume is selected, verify the status of each volume that is mapped to host in the Details section.
To map the PowerFlex to the VxRail dynamic nodes:
1. In the vSphere Web Client, go to Menu > host and cluster.
2. Select one of the VxRail dynamic node, configure > Storage > Storage Devices and verify that the mapped PowerFlex volume is listed as a LUN, as shown in the following figure:
3. Right click on the cluster and select Storage > New Datastore.
4. Select VMFS as the datastore type.
5. In Name and device selection:
6. Select VMFS version as VMFS 6 and click Next.
7. Specify Partition configuration and click Next.
8. In the Ready to Complete page, review the datastore configuration information.
9. Click Finish.
10. Verify that all the mapped hosts are listed under the newly created datastore.
a. Select the newly created datastore and click the Hosts tab, after few minutes it will list all the mapped VxRail nodes.
The PowerFlex volumes are now mapped as storage to VxRail dynamic nodes.
To create a new VM storage policy:
1. In the vSphere Web Client, navigate to Menu > Policies and Profiles.
2. Select VM Storage Policies from the left side of the page and click Create VM Storage Policy.
3. In the Name and description page that opens, update the name.
4. On the Policy structure page, under Host based services, select Enable host-based rules.
5. In the Host based services page, apply these settings:
6. The Storage Compatibility page lists compatible datastores.
7. Under Review, verify the details and click Finish.
8. Verify that the newly created PowerFlex datastore is visible under the storage compatibility of the new VM storage policy.
