11. Restart HP SUM.
Performing these steps allows HP SUM to function, although after a period of time (ranging
from minutes to hours), McAfee disables HP SUM access.
IPv6 network issues
If HP SUM cannot connect to the remote server, you might receive a Discovery Failed error. Discovery
failures can be caused by third-party storage, failure to access the remote target server, and an
inability to access system resources. For IPv6 networks, host discovery failures can be caused by
the incorrect configuration of the IPv6 network.
Solution: Follow the steps for your environment to correctly configure the IPv6 network.
Troubleshooting HP SUM in IPv6 Windows Server 2003 environment
To validate that the IPv6 network is configured correctly for HP SUM support, you must verify the
following based on your operating system version.
• Validate that the addresses are site-local. Site-local addresses normally start with "FEC0:".
Global and link-local IPv6 addresses are not supported when the remote target is Windows
Server 2003.
• Validate that you can ping the remote target server. With computers running Windows, you
can still use the ping command to ping IPv6 addresses:
ping <ipv6 address>.
• Ensure you can ping the IPv6 loopback address:
ping ::1
• Use the DNS hostname instead of IPv6 address to ensure the address is correct.
• Ensure you have installed the IPv6 protocol. It is not installed by default in Windows Server
2003. Be sure to reboot the server after installing the protocol to ensure addresses are properly
obtained.
• Verify that you can connect to the admin$ share using the credentials within HP SUM by
issuing the following command at a console prompt:
net use * \\<ipv6-address>.ipv6-literal.net\admin$ /user:<username>
net use * \\fec0::2.ipv6-literal.net\admin$ /user:administrator
