The shared VMDK volume size was increased to 50 GB, but RecoverPoint still sees the old size, which was 25 GB.

The process, to increase shared disks protected with RecoverPoint, is different from nonshared disks. In nonshared disks, RecoverPoint detects the size change and replicate those changes to the Replica VM. In shared disks, RecoverPoint cannot replicate those changes to the replica VM, as the shared disks have a special configuration in order to be protected.

Workaround:

In order to avoid the issue stated above, use the below procedure to increase shared disks/s size.

 

1. Access RecoverPoint for Virtual Machines (RecoverPoint for Virtual Machines) Plugin.
2. Select Protected VMs.
3. Find which VM/s have the shared disk/s and press Protection Policy.
4. Clear the shared disk/s to stop the replication and Update Policy. (Has to be done for all the protected VMs sharing the disk being resized.)

Resolution:

RecoverPoint for Virtual Machines is working by design.
