verified by entering net use at a command prompt. If a share to the target IP address \admin$ share exists, delete it, and then attempt 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: \\\admin$ for the target server IP address or DNS name. When the connection is validated, ensure that it is deleted by entering net use x: /d at the command prompt. • Ensure the user ID being used to connect to the target IP address server is part of the administrator's or Linux root equivalent group. If it is not, HP SUM blocks installation to the target. • Ensure WMI is enabled and running on all Windows target servers. • For Windows target servers, enter the user name in DOMAIN\USER format, where is the administrative user name, and is either the NETBIOS computer name or the Active Directory domain name for this user account. • For Linux, ensure the SSH port is not blocked by a firewall. • 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. For more information, see "Network ports used by HP SUM" (page 57). • The Symantec Endpoint Protection product blocks HP SUM ability to communicate with remote targets if the Network Threat Analysis feature is enabled. Disable this feature while HP SUM is in use on the workstation. • Examine the trace directories for connection problems. For more information, see "Collecting trace directories" (page 59). • Ensure the server has a valid serial number. HP SUM hangs during discovery If a system hang is observed during HP SUM discovery and the system is connected to external storage, in most cases disconnecting the external storage should resolve the issue. If discovering an ESXi 5 server, make sure you have installed the CIM providers from HP. You may download this within the "Offline Bundle Utilities" on ESXi 5 server downloads from the HP support website at http://www.hp.com/support, or they come already bundled in the HP custom ESXi image HP SUM hangs during boot If the system hangs while booting, check that the IP address 192.168.0.1 is not being used on your network. If this IP address is being used on the network, you might have to disconnect the server from the network to perform updates.

By default, the target firewall is enabled in Linux. To recover remote Linux functionality, the target and host firewall must be disabled or reconfigured to allow IP traffic through the ports needed by HP SUM to deploy firmware.

verified by entering
net use
at a command prompt. If a share to the target IP address
\admin$ share exists, delete it, and then attempt 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 IP address or DNS name. When the connection is validated, ensure that
it is deleted by entering
net use x: /d
at the command prompt.
•
Ensure the user ID being used to connect to the target IP address server is part of the
administrator’s or Linux root equivalent group. If it is not, HP SUM blocks installation to the
target.
•
Ensure WMI is enabled and running on all Windows target servers.
•
For Windows target servers, enter the user name in
DOMAIN\USER
format, where
<user>
is the administrative user name, and
<domain>
is either the NETBIOS computer name or the
Active Directory domain name for this user account.
•
For Linux, ensure the SSH port is not blocked by a firewall.

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.
