PowerProtect: How to remove orphan file level restore drives from a virtual machine

This procedure may be of use where

• Orphaned hard disks remain attached to the virtual machine after a failed FLR.
• Disks are shown as independent and located on a temporary datastore in vSphere.
• The temporary datastore is named in the format: DELL-vProxy-<hostname>-xxxxxxxxx.

This may be caused where the FLR workflow failed to clean up temporary NFS-mounted disks due to an incomplete or interrupted restore session. As a result, the virtual machine retains orphaned disks and the associated temporary datastore remains mounted.

The steps below guide to remove orphaned FLR drives. Depending on where the FLR workflow failed, not all steps may be necessary.

1.) Virtual Machine Cleanup

• Log in to the affected client operating system.
• Confirm if the FLR Agent still has the mount point available in the temporary directory: 
  • Windows: C:\Program Files (x86)\EMC\vProxy FLR Agent\flr\mountpoints\FLR#########
  • Linux: ls /opt/emc/vproxyra/flr/mountpoints/FLR#########
• Unmount the drives from the temporary mount point directory:
  • Windows: vflrmount.exe -d -v remove "C:\Program Files (x86)\EMC\vProxy FLR Agent\flr\mountpoints\FLR#########"
  • Linux: /opt/emc/vproxyra/bin/vflrmount -d -v remove /opt/emc/vproxyra/flr/mountpoints/FLR#########

2.) vSphere Environment Cleanup:

• Open the vSphere Web Console.
• Select the virtual machine "Options > Edit Settings."
• Expand the hard disks on the "DELL-vProxy-myppdm.my-domain.com-xxxxxxxxx" datastore and select "Remove device." Do not select "Remove device and data."
• Clear the value for the "Dell VM Direct Engine Session" Custom Attribute on the affected virtual machine.
• Browse to the vSphere Web Console datastore view.
• Select the "DELL-vProxy-myppdm.my-domain.com-xxxxxxxxx" datastore and use the "Unmount datastore" option.

3.) Data Domain Cleanup:

• Open the Data Domain Console and browse to "Protocols > NFS".
• Select the Network File System (NFS) export with the "DELL-vProxy-myppdm.my-domain.com-xxxxxxxxx" acronym and "Delete."

4.) PowerProtect Appliance Cleanup:

• Open an SSH session to PowerProtect Data Manager and authenticate with the admin account.
• Use the Switch User command and authenticate with the root password: sudo su
• Stop the vproxyd service: systemctl stop vproxyd.service
• Remove any available FLR blog files from the /opt/emc/vproxy/runtime/state/vproxyd directory: rm -r FlrMountSessions* FlrBrowseSessions* FlrRecoverSessions*
• Remove the current date FLR session logs from the /opt/emc/vproxy/runtime/logs/recycle/vproxyd directory: rm -r ./[YYYYMMDD]/*
• Start the vproxyd service: systemctl start vproxyd.service
