Dell PowerFlex 4.6.x Administration Guide

Replace the initial CloudLink cluster

Use this procedure to replace the CloudLink 7.1.9 cluster.

1. From the CloudLink 7.1.9 web console, generate a CloudLink backup:
   1. Browse to the IP address or hostname of one of the CloudLink Center VMs.
   2. Log in using the secadmin credentials.
   3. Navigate to System > Backup.
   4. To generate a new key and backup file, click Generate New Backup.
   5. Download both the key and backup file and store together. These files are required while restoring. If you have a CloudLink 7.1.9 cluster, backup from one of the cluster members is sufficient.
2. Power off the CloudLink 7.1.9 VM from step 1. The connected nodes are connected to another member of an existing cluster.
3. Deploy a new CloudLink 8.1.x OVA:
   1. From the VMware vSphere Client, log in to the vCSA and click Menu > Shortcuts > Hosts and Clusters.
   2. From PFMC datacenter, right-click PFMC Cluster and select Deploy OVF Template.
   3. Select the local file and click Upload Files.
   4. Select the CloudLink OVA and click Open > Next and enter the name.
   5. Click Next thrice and select the datastore and virtual disk format: Thin Provision.
   6. Click Next, select the CloudLink Center associated VLAN, and click Next > Finish.
4. Before powering on the CloudLink 8.1.x VM for the first time, configure the network settings to retrieve the same static IP address which was originally assigned to the now powered down 7.1.9 CloudLink Center (from step 2):
   1. Navigate to the VM from the vCenter inventory.
   2. On the Configure tab, expand Settings, select vApp options, and click Edit....
   3. From OVF Details > OVF Environment transport , select the VMware Tools check box, and click OK.
   4. Under OVF Settings, ensure that View OVF Environment and OVF Environment Transport: VMware Tools and Installation boot are disabled as VM is in a powered off state.
   5. Under Properties, click ADD and create separate entries for the following values. Ensure you add the key ID and label as specified in the following table for all labels.

      Table 1. Key IDs and labelsEntries you need to create for Key IDs and labels

      Key ID	Label
      cl.interface.0.ip.4.netmask	IPv4 netmask
      cl.interface.0.ip.4.gateway	IPv4 gateway
      cl.interface.0.ip.4.address	IPv4 address
      cl.hostname (optional)	Hostname (optional)

      After each entry, click Save.
   6. For each item created in the previous step, select Set Value and set the static IP address, gateway, netmask, and hostname (optionally).
   7. Snapshot the setting values (if desired).
5. Power on the CloudLink 8.1.x VM:
   1. From the VMware vSphere Client, log in to the vCSA, click Menu > Shortcuts > Hosts and Clusters.
   2. From PFMC datacenter, click PFMC cluster, and right-click CloudLink 8.1 VM.
   3. Click Power > Power ON.
6. Once the CloudLink VM boots up, the IP configuration should be set as the static IP address and the web console should be reachable.
7. Browse to the hostname or IP address of the powered on CloudLink Center 8.1.x.
8. From Boot Terms and EULA, accept the terms and conditions and set the secadmin credential password (use recorded value).
9. The initial configuration window appears on top of the main console view.
10. To set the login password to the existing CloudLink 7.1.9 VM login password, click Change password.
11. Set the console password to the existing CloudLink 7.1.9 VM password. This may be defined as a CloudLink console or an OS user. Click Change Console Password.
12. If you configured the optional hostname parameter, the INITIAL CONFIGURATION wizard contains the value. If not, a randomly affixed name appears. If you intend to modify the hostname, enter a name and click Next. The INITIAL CONFIGURATION wizard reloads and may take a minute or so to reconnect. You may have to refresh the browser.
13. Click Next and wait for the browser to refresh.
14. Click Deployment Type and select Restore from Backup.
15. Select CloudLink 7.1.5+ for Backup File Version and set CloudLink Data is backed up to Yes. Click Next.
    A warning appears, directing to restore only on standalone node (future nodes are added as cluster members).
16. Click Next.
17. When prompted for the server name or IP address, retain the pre-populated IP address of the new VM and click Next.
18. To upload the key file and backup file, click Folder, browse and select the key or backup file, and click Open. Click Restore.
    Wait for a couple of minutes until restore completes successfully.
19. Log in and check if the restore is successful with CloudLink Center 8.1.x.
20. Confirm the configuration data (DNS, NTP, etc) from the previous instance, such as, the time servers. Click Server > Time.
