Troubleshooting host discovery
If you encounter discovery problems, complete the following checklist to ensure that discovery was
set up correctly. For more complete information about troubleshooting adapters, refer to the
Adapters Troubleshooting Guide.
1. Verify IP connectivity by issuing a ping command to the host.
a. Open the command prompt.
b. From the server, type
ping Host_IP_Address .
2. If the host is responding to ping, but discovery still fails, verify that HCM agent is up or not by
browsing to the following URL:
https://Host_IP_Address:34568/JSONRPCServiceApp/JSON-RPC
If HCM agent is running and reachable, you should receive a prompt of credentials and then
show an Error 500 (No Reason) result page.
3. Verify that firewall port 34568 is open.
There are firewall issues with the HCM Agent on Windows 2008 and VMware systems. When
installing the driver package on these systems, open TCP/IP port 34568 to allow agent
communication with the Management application.
• For VMware, use the following commands to open port 34568:
 esxcfg-firewall –o 34568,tcp,in,https
 esxcfg-firewall –o 34568,udp,out,https
• For Windows, use Windows Firewall and Advanced Service (WFAS) to open port 34568.
VM Manager discovery
The Management application enables you to discover VM managers. VM Manager discovery
requires vCenter Server 4.0 or later.
NOTE
vCenter discovery time is dynamically determined based on the number of hosts being managed by
the vCenter. For every 50 hosts managed, the vCenter collection period increases 30 minutes.
For 0-50 hosts managed, the collection duration is 30 minutes; for 50-100 hosts managed, the
collection duration is one hour, and so on.
