Dell NetWorker remediation is available for multiple security vulnerabilities that could be exploited by malicious users to compromise the affected system.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. In certain situations, it is necessary to perform a restore from the command line (CLI). This article provides general information about performing a Virtual Machine (VM) Image Restore using nsrvproxy_recover.

The NetWorker VMware Protection integration is configured with the vProxy Appliance. The vProxy backups fail when they run against a specific vProxy in the environment. The NetWorker Management Console (NMC) shows a warning message "vProxy <vProxy FQDN> is not available." The NetWorker server daemon.raw file error indicates the NetWorker server is unable to connect to the vProxy over port 9090.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy Appliance. The backup of a virtual machine fails to complete in the environment.  The NetWorker Management Console message simply indicates it is unable to backup virtual disk "Hard disk 1". The ESX host that hosts the vProxy appliance has an issue with the HBA and cannot retrieve disk information required to perform the backup.

This article provides a general overview for troubleshooting network connectivity between systems that are involved during backup and restore operations of virtual machines (VMs) protected by the NetWorker VMware Protection (NVP) vProxy appliance.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. The vProxy encounters an error while trying to be registered to NetWorker through the NetWorker Management Console (NMC).

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. vProxy backups are failing with an error message that suggests there is a permissions issue. The vCenter user account is not set on the vCenter root, or it is missing required permissions. ​

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. When the vProxy is attempting to perform backups, certain virtual machines (VMs) consistently fail. The NetWorker Management Console (NMC) message says "Backup is CANCELED."

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. The vProxy appliance goes into an invalid state during backup. The NMC may show an alert stating "vProxy is unavailable". The vProxy shows inactive in vSphere. The vProxy is unresponsive and cannot perform backups in its current state.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. When attempting to add a vProxy in the NetWorker Management Console (NMC), it fails with error "Unable to log in to vCenter." The vProxy cannot resolve the vCenter name because it is not configured with a proper DNS. Edit the vProxy /etc/resolv.conf to include a proper DNS that can resolve the NetWorker Server, vCenter Server, and Data Domain.

vProxy FLR fails with error "Failed to log in to Data Domain service". The mount session logs point to a TCP network connection failure. Either the TCP connection was reset or the context deadline was exceeded.

NetWorker VMware Protection (NVP) vProxy Virtual Machine (VM) FLR or Instant Access recovery fails with error "Failed to login to Data Domain service"… "remote error: TLS: handshake failure."

This KB provides a general overview of NetWorker services and ports.

A NetWorker VMware Protection (NVP) Virtual Machine (VM) File Level Restore (FLR) fails to mount. Instant Access restore may also fail. The error logging returns that the vProxy failed to log in in to the Data Domain because the REST service on the Data Domain is disabled.

A Virtual Machine (VM) File Level Recovery (FLR) is being performed through NetWorker, using the NetWorker VMwar Protection (NVP) vProxy appliance. During the FLR, the mount process fails. The error returned is that the nsrvproxy_flr process failed to log in to the Data Domain.

NetWorker vProxy Virtual Machine (VM) workflow is marked as failed but all VMs report successful. Error: "Unable to find selected VM work item with UUID "UUID" in vCenter, the work item will be skipped."

NetWorker VMware Protection (NVP) Virtual Machine (VM) backups complete successfully but the workflow is marked as failed. The backup action log reports "Unable to find selected vCenter container work item with ID "host-###" in vCenter, the work item will be skipped."

NetWorker VMware Protection (NVP) backup policies are marked as failed but all Virtual Machines (VM) were successful. Error showing in the policy summary: Unable to find selected vCenter container work item with ID "vm-MOREF" in vCenter, the work item will be skipped.

NetWorker vProxy backups are being marked as failed but all Virtual Machines (VM) are backed up successfully. The backup action log reports "Unable to find selected vCenter container work item with ID XX in vCenter"

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. When a Virtual Machine (VM) is backed up, we do not store VM attributes such as the VM's tags and annotations. VM tags and annotations are part of the vCenter, not the individual VM configuration files. Since we do not backup these details, they are not restored and must be manually set after the restore completes.

A NetWorker VMware Protection (NVP) backup or restore is started; however, the Virtual Machines (VM) in the workflow sit in a "waiting to run" state. VM restore sessions start but do not progress, no write session is established. vProxy backup and recover jobs must be canceled manually.

Root account access through the vProxy appliance is lost.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. When attempting to install the vSphere web client plugin from the NetWorker Management Console (NMC), the plugin installation fails. During a review of various logs, it is found that there are many authentication errors that occur when installing the vCenter plugin. The NetWorker Server authentication database is corrupt. Reinstall NetWorker with a fresh installation of the authentication database.

This KB provides instructions for how to reset the NetWorker VMware Protection (NVP) vProxy appliance credentials.

This article provides instructions for unlocking the NetWorker VMware Protection (NVP) vProxy appliances admin account. It also provides an overview of how to determine where failed authentication attempts are coming from.

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. For information regarding vProxy compatibility with NetWorker, Data Domain Operating System (DDOS), vCenter, and ESXi versions, please refer to the Online Compatibility Guide.

After replacing the NetWorker certificate, vCenter plug-in installation fails due to certificate mismatch.
