Avamar Plug-in for Hyper-V VSS : Hyper-V backups "Failed to complete operation on all remote client"

Article Number: 504472
Version: 6
Article Type: Break Fix
Last Published: 04 Apr 2020
Summary:
Issue


Hyper-V backups intermittently fail with errors similar to the following:

avhypervvss Error <42447>: Failed to complete operation on all remote client(s).
avhypervvss Error <41629>: Failed to gather status from remote clients
avhypervvss Error <41659>: Backup did not complete successfully
Cause
Subworkorder communication delays between primary and secondary nodes in the Hyper-V cluster.
Resolution
Edit the avhypervvss.cmd file in the shared var directory and add the following flag:  

--subworkorder-timeout=20

This flag will allow the secondary node an additional 20 minutes to receive and acknowledge the subworkorder to the primary node.  Increase the value if necessary.
