Resize a VMDK of a VM replicated by vSphere Replication ends with Error „Invalid or unsupported virtual machine configuration“

Resize a VMDK of a VM replicated by vSphere Replication ends with Error „Invalid or unsupported virtual machine configuration“ 

when you trying resize a VDMK of VM thtat is configured for replication using vSphere Replication you see an error. This is caused because the virtual machine files are protected by vSphere Replication using Site Recovery Manager. 

The resolution to bypass this block is simple, follow my steps: 

Document Virtual Machine Replication Settings

Ensure that you know the path of the Target Location.

Ensure that you know Replication Settings. 

Rename the replicated vm datastore folder

original name is „TKA-Install“

i changed folder name to „TKA-Install_renamed“

Stop the virtual machine replication

go back to the Site Recovery and remove VM from replications

Remove

Completed ! 

Expand Source-live Virtual Machine disk (VDMK) 

Expand Targed-Replicated Virtual Machine disk (VDMK) 

 

use tool vmkfstools -X sizeGB NameOfDisk.vmdk

rename the folder to original name in my case back to „TKA-Install“ 

Configure Replication

Create a new replication job 

 

Select target datastore, where is stored replica folder and click to „Select seeds“

Click on „The selected seeds are correct“ 

Configure replication settings as before. 

DONE !
