HP StorageWorks P9000 Performance Advisor Software v5.4 Troubleshooting and FAQs Guide (T1789-96336, April 2012)

Cause
An Unknown Host error is displayed when you view the host agent details in the Host Information
table in P9000 Performance Advisor. This is because, the host name might not be resolved.
Resolution
Do the following:
• Ensure that the host is up and running. Try to ping the host (command prompt>ping <hostname>).
• The host browser-side system is able to resolve the host name. Try to ping the host (command
prompt>ping <hostname>).
If the second option fails, you must set the DNS configuration. To configure, do the following:
1. Go to Start > Control Panel > Network Connections.
2. Right click Local Area Connection, select Properties.
3. On the General tab, double-click Internet Protocol (TCP/IP).
The Internet Protocol (TCP/IP) properties Window is displayed.
4. Click the Advanced tab.
The Advanced TCP/IP Settings window is displayed.
5. On the DNS tab, select Append DNS suffixes.
6. Add host name suffix.
7. Click OK to save the settings.
