If you are receiving an HPSUM Connection Error
or Discovery Failed messages, follow these main troubleshooting
tips.
Ensure your workstation does not have an
existing connection to the ADMIN$ share on the target IP address.
If it does, it prevents HP Smart Update Manager from connecting to
the remote server's share because Windows only allows one
connection from a client to a server's share. This can be checked
by entering net use at a command prompt. If there is an existing
share to the target IP address \admin$ share, delete it and try the
installation again.
Ensure that the target IP address server's
admin$ share is accessible. Validate the target server can be
accessed by entering net use x:
\\<ip_address_or_dns_name>\admin$ for the target server's IP
address or DNS name. When the connection is validated, ensure that
it is deleted by entering net use x: /d at command prompt.
Ensure the user ID being used to connect to
the target IP address server is part of the administrator's group.
If it is not, HP Smart Update Manager blocks installation to the
target.
Ensure WMI is enabled and running on all
Windows target servers.
For Linux, ensure the SSH port is not
blocked.
In some rare cases, external storage
enclosures may cause HP Smart Update Manager to report a discovery
failure. To resolve this problem, disconnect the external storage
until the firmware updates are completed.
For Linux, ensure that the target server can
be contacted through SSH and that the scp command is available to
securely send files to the target server.
Ensure the firewall ports on any routers in
the network as documented in the Enabling ports in HP Smart Update
Manager section of this document.
The Symantec End Point Protection product
(SEP) blocks HP Smart Update Manager ability to communicate with
remote targets if the Network Threat Analysis feature is enabled.
Disable this feature while HP Smart Update Manager is in use on the
workstation.
Examine the OpMan.trace, IPScout.trace,
OSScout.trace, discagent.trace and discmanager.trace files to
determine the cause of the failure. For more information, see
Collecting trace directories.
