Symptoms

  • One or more proxies show a status of "Unknown" in the UI.

  • Proxy status updates using Proxy Deployment Manager (PDM) fail during the getProxyStatus operation.

Error Details

In the PDM log file (/usr/local/avamar/var/log/vcs/deploymanager.log) on the Avamar server, the following error is shown:

<date> ERROR [:1-8543-exec-10][impl.ProxyService#   getProxyStatus]: getProxyStatus:
java.rmi.RemoteException: WBEMException; nested exception is:
        WBEMException: CIM_ERR_INVALID_PARAMETER (Malformed URI)
        at com.emc.avamar.vmware.cimsdk.cim.SblimCIMProxyMgmtConnection.login(SblimCIMProxyMgmtConnection.java:79)

 

Cause

This issue occurs when the proxy's hostname contains an underscore (_). According to Request For Comment (RFC) 1035This hyperlink is taking you to a website outside of Dell Technologies., underscores are not valid characters in Domain Name System (DNS) hostnames.

The Proxy Status feature uses Java-based CIM/WBEM libraries that enforce strict Uniform Resource Identifier(URI) validation. Hostnames with underscores are treated as malformed, resulting in the CIM_ERR_INVALID_PARAMETER error.

Example:

  • ❌ proxy_idpa_01.example.com - Not allowed

  • ✅ proxy-idpa-01.example.com - Allowed

 

Resolution

To resolve this issue, redeploy the affected proxy using a hostname that does not contain an underscore. Use hyphens (-) instead of underscores to ensure compatibility with DNS standards.
