Dell PowerFlex Appliance with PowerFlex 4.x Administration Guide

Add the hyperconverged resource group back to PowerFlex Manager

Add an existing service to discover and import hardware resources that were not originally deployed with PowerFlex Manager.

1. Log in to PowerFlex Manager.
2. Click Lifecycle > Resource Groups.
3. Click Add Existing Resource Group and click Next.
4. Enter the resource group name that was removed in the Name field.
5. For the Type of resource group, select Hyperconverged.
   PowerFlex Manager checks to see whether there are any vCLS VMs on local storage. If it finds any, it puts the service in lifecycle mode and gives you the opportunity to migrate these to shared storage.
6. Under Firmware and Software Compliance, select the version recorded earlier.
7. Click Next.
8. Choose one of the following network automation types:
   • Full Network Automation
   • Partial Network Automation

   When you choose Partial Network Automation, PowerFlex Manager skips the switch configuration step, which is normally performed for a service with Full Network Automation. Partial network automation allows you to work with unsupported switches. However, it also requires more manual configuration before a deployment can proceed successfully. If you choose to use partial network automation, you give up the error handling and network automation features that are available with a full network configuration that includes supported switches.

9. On the Cluster Information page, enter a name for the cluster component in the Component Name field.
10. Select volumes for the cluster settings:
    For a hyperconverged or compute-only service, select the following:

    1. Target Virtual Machine Manager - Select the VMware vCenter name where the cluster is available
    2. Data Center Manager - Select the data center name where the cluster is available
    3. Cluster Name - Select the name of the cluster you want to discover
    4. OS Image - Select the image or choose Use Compliance File ESXi image if you want to use the image provided with the target compliance version. PowerFlex Manager filters the operating system image choices to show only ESXi images for a hyperconverged or compute-only service.
    For a storage-only service, select the following:

    1. Target PowerFlex Gateway - Select the gateway where the cluster is available
    2. Protection Domain - Select the name of the gateway where the cluster is available
    3. OS Image - Select the image or choose Use Compliance File Linux image if you want to use the image provided with the target compliance version. PowerFlex Manager filters the operating system image choices to show only Linux images for a storage-only service.
11. Click Next.
12. On the OS Credentials page, select the OS credential that you want to use for each node and SVM.
13. Click Next.
14. Review the inventory on the Inventory Summary screen.
15. Click Next.
16. On the Network Mapping page, review the networks that are mapped to port groups and make any required edits.
17. Click Next.
18. Review the Summary page and click Finish.
    Repeat for each site until all systems in the replication topology have been converted.
