vSphere Replication prevents you from resizing the virtual machine disk file during replication. If you did not use replication seeds during configuration of the target disk, vSphere Replication deletes the target disk when you stop the replication.

About this task

To resize a virtual machine disk if you did not initially use replication seeds, you must perform a test recovery, clone the recovered virtual machine, and reconfigure the disk manually using replication seeds.

Procedure

  1. Run a test recovery for the virtual machine.
  2. Clone the recovered virtual machine on the same datastore where the replication occurs after you reconfigure the replication.
  3. Revert the test recovery.
  4. Unconfigure the replication.
  5. Resize the disk on the source site.
  6. Resize the disk on the cloned virtual machine on the target site.
  7. Unregister the cloned virtual machine on the target site, but do not delete the disks.
  8. Enable replication by using the disks of the cloned virtual machine as seeds.
