Hi DurgaReddy

For FQDN change? Need VCSA 6.7 U3 min.
you may refer to this link. https://blogs.vmware.com/vsphere/2019/08/changing-your-vcenter-servers-fqdn.html.
Have also to reinstall the HPE SimpliVity plugin and regenerate certificates, refer to the below link
https://kb.vmware.com/s/article/2112283.
Then use dsv-update-vcenter on each ovc

Hope this helps.!!

Hi DurgaReddy,

Thank you for writing us.

Please follow the steps that was provided by my peer Mahesh.

After renaming the vCenter FQDN and re-generating the vCenter certificates. Uninstall and Re-install the SimpliVity Plug-In.

Note: If there are multiple vCenters used for the SimpliVity Federation in the Linked Mode. Then the SimpliVity Plug-In must be uninstalled and re-installed on all the vCenters if the FQDN is changed on all the vCenters.
Then run the below command on all the OVCs one after the other in the Federation :

dsv-update-vcenter --server "ip address of the vCenter server" --user "administrator@vsphere.local"

<administrator@vsphere.local></administrator@vsphere.local>
Enter the administrator@vsphere.local password

Note: The OVC will go for a reboot after running the above command. Ensure all the VMs in the cluster has the Storage HA. In order to verify if all the VMs has the Storage HA, run the command, "svt-vm-show" the "Storage HA" must show as "Yes" on all the VMs. If there is a single node in the cluster, then all the VMs must be powered off before running the above command.

Example: 
1. SSH (Putty) to the OVC using the OVC Management IP
2. Run the command svt-federation-show - Check all the OVCs shows "Alive" in the output
3. Run the command svt-vm-show. Check if all the VMs' "Storage HA" shows as "Yes" in the output
4. Elevate to root by typing - < sudo su >
5. Then type < source /var/tmp/build/bin/appsetup >
6. Run the command dsv-update-vcenter --server "ip address of the vCenter server" --user "administrator@vsphere.local"<administrator@vsphere.local> on the first OVC</administrator@vsphere.local>
7. Wait for the OVC to completely reboot
Note: You will lose the SSH(Putty) session after the OVC reboots. Hence, you have to restart the SSH(Putty) session
8. After the OVC reboots. The SVTFS will take some time to load. Wait for 15-20 Minutes
9. Run the command svt-federation-show - Check the rebooted OVCs shows "Alive" in the output
10. Run the command svt-vm-show. Check if all the VMs' "Storage HA" shows as "Yes" in the output
11. Once all the VMs' "Storage HA" shows as "Yes. Proceed with the next OVC
