Symptoms

NetWorker VMware Protection integration is configured with the vProxy Appliance. The VMware Backup action fails to run work orders against a specific vProxy Appliance in the environment. 

The Backup action log shows:

MM/DD/YYYY HH:MM:SS VM_NAME: Unable to start backup on vProxy 'MYVPROXY.MYDOMAIN.COM': libCURL: function "curl_easy_perform" returned error 60: "An error occurred as a result of an SSL protocol failure. For example, failure to verify server/CA certificate during the handshake. MYVPROXY.MYDOMAIN.COM:9090 ".

Cause

The vProxy certificate that resides in the NetWorker Resource database (nsrdb) does not match the certificate from the vProxy appliance.

Resolution

The vProxy appliance must be re-registered against the NetWorker Server to update the certificate in the nsrdb.

Delete the vProxy appliance from the configuration and register it with the steps documented in the Dell NetWorker VMware Integration Guide.

Alternatively, the appliance can be re-registered by following:

  1. 1. Delete the vProxy from NetWorker the vProxy from the NetWorker Management Console (NMC) under Devices->VMware Proxies. Similarly, the NetWorker Web User Interface (NWUI) may be used to and delete the vProxy from Protection->VMware Proxies.
  2. Connect to the vProxy over SSH and log in as 'admin'.

mv /opt/emc/vproxy/runtime/state/vProxyRegistry.dat /opt/emc/vproxy/runtime/state/vProxyRegistry.dat-`date -I`

       5. Reboot the vProxy: reboot

       6. Once the vProxy is back online, add it back to NetWorker from the NMC or NWUI.
