Symptoms

During a Hyper-V GLR browse operation, the Restore window in Avamar Administrator displays “Err” in the tree view, and no further action occurs.The following errors appear in avagent.log on the Hyper-V GLR client avagent Warning <5464>: Invalid browse request (6)No PID to executable association avagent Warning <6690>: CTL workorder "Browse" non-zero exit status 'code 536870925: externally cancelled' ... avagent Error <5365>: Cannot connect to 192.168.1.1:28001. avagent Error <5449>: No executable associated with PID 3033-Hyper-V GLR. avagent Error <5365>: Cannot connect to 192.168.1.1:28001. The avhyperv_plugin.log file shows messages similar to: avhypervglr Info <9528>: Cancel request received - no assistant or aborted assistant

Cause

Network connectivity issues between the Avamar grid and the Hyper-V client prevent GLR browse operations, even if backups complete successfully.

Resolution

Verify Port Connectivity From the Avamar grid, test connectivity to the Hyper-V client using telnet: telnet hyperv.avamar.com 28002 telnet hyperv.avamar.com 30002 If session security is enabled, the Avamar agent listens on port 30002 instead of 28002.GLR requires successful connectivity on one of these ports. Check Firewall Settings Temporarily disable Windows Firewall on the Hyper-V client for testing purposes. Test Network Performance Run iPerf tests between the Avamar server and the Hyper-V client to identify bandwidth or latency issues.Pay attention to packet flow from the grid to the client.Refer to Dell KB articles for guidance: for example: Avamar: Troubleshoot network issues causing Windows backup performance to be very slow Alternative Workaround Redirect the Hyper-V GLR browse operation to another Windows client with the Hyper-V GLR plug-in installed.
