[VMC on AWS] Resize vSphere Replication Protected Virtual Machine Disk Files

Products

• VMware Cloud on AWS

Issue/Introduction

This article provides information on resizing a vDisk protected to VMware Cloud (VMC) on Amazon Web Services (AWS) using vSphere Replication, without doing a full re-sync.

Resolution

To achieve this on VMC:

1. Remove the VM from the Site Recovery Manager (SRM) protection group, if this protection is configured.
2. Perform recovery from Replications tab, without powering off the source VM.
3. There should now be a powered off VM at the target site and you can edit the settings of the VM and resize the disk from there.
4. Unregister the VM from the target vCenter inventory, but keep the disks.
5. Configure replication using seeds.
6. Re-add the VM to SRM protection group, if needed.

Note: vsphere replication 8.3 and above.
Seamless disk re-sizing. You can increase the virtual disks of virtual machines that are configured for replication, without interruption of ongoing replication. The virtual disk on the target site will be automatically resized
