Environment

VMware Live Cyber Recovery 7.27.x

VMware Live Cyber Recovery 7.26.x

Cause

LWD Filter can be leftover on the VMs if the VMs was protected by VLCR before and VM was either removed or Protection Group associated to the VM was deleted

Resolution

• Make sure VM is currently not protected by vSphere Replication or HCX or third party backup solutions which leverages LWD. 
• Make sure VM is not running on any snapshots
• Disable LWD filter by logging to DRC Connector VM as "admin" user (Password for admin user can be obtained from VLCR UI)
• Run these commands to obtain temporary "root" password:

entersupportmode

dev root enable

• Take another SSH to DRC Connector VM and login as root user with the temporary password obtained from above step
• Run the command to deactivate the lwd filter:

drc deactivate-hfs --vcenter-ip <vcenter_ip> --name-pattern <vm_name>

Example : drc deactivate-hfs-bulk --vcenter-ip 10.41.14.4 --name-pattern Test
