Overview:

The vmconfig utility is troubleshooting utility that can be used to identify potential impacts to NetWorker VMware Protection (NVP) operations. For example, it can list if a VM is still locked from backup; or if the VM has VMware Change Block Tracking (CBT) enabled or disabled. Additional uses are detailed in the below Instructions field. The ProxyHC utility can also be used to perform many of the same functions; however, vmconfig is provided on the vProxy by default where ProxyHC must be downloaded and placed on the vProxy. For more information about ProxyHC, see the Additional Info section of this article.

 

Instructions:

 

1. Log in to the vProxy as admin, then switch to root:

sudo su -

2. Change to the bin directory:

cd /opt/emc/vproxy/bin

3. Run the command below to load the library path:

source ../unit/vproxy.env

NOTE: "error while loading shared libraries" may appear while using vmconfig if the above step is not performed.

4. Run the vmconfig command.
