The issue occurs when automatic replication of new disks is activated.

Problem

When you both remove and add a protected disk on the same SCSI device in a single step, the replication enters Error state:​
The set of disks on the vSphere Replication Server does not match the source set for replication 'vm name'.

Solution

  • Workaround 1: Replace disk with two separated configuration operations.
  • Workaround 2: If you replaced the disk on the SCSI device with a single configuration operation, reconfigure the replication.
