Troubleshooting 25
• When I install storage components and restart the server, there are one or more new entries in the
LILO or GRUB tables for kernels to boot from. Is this normal?
Yes, this is normal. Each storage driver reconnects the driver to the base kernel and adds a new
entry in the LILO or GRUB tables that appear at boot. To ensure that you get the kernel with the latest
drivers, select the last entry in the table.
• I attempted to install a component that compiles from source code, but the installation fails on the
make command.
The build tools necessary to complete the build from kernel source are not located on the server
where the LDU is deploying. To build from source RPMs, the following RPMs must be installed on the
server where the HP SUM is deploying software:
o gcc-2.96-108.1 or later
o cpp-2.96-108.1 or later
o binutil-2.11.90.0.8 or later
o glibc-devel-2.2.4-26 or later
• How do I use HP SUM over a firewall? Which ports will I need to open? Are they configurable?
The ports that HP SUM uses cannot be configured. When HP SUM port initiates communications to
remote targets, it uses several well-known ports depending on the operating system. For Linux, HP
SUM uses port 22 (SSH) to start communications with the remote target.
HP SUM uses defined ports to communicate between the remote target and the workstation where
HP SUM is executing. When you run HP SUM, it uses the administrator/root privileges to
dynamically register the port with the default Linux firewalls for the length of the application
execution, and then closes and deregisters the port. All communications are over a SOAP server
using SSL with additional functionality to prevent man-in-the-middle, packet spoofing, packet replay,
and other attacks. The randomness of the port helps prevent port scanning software from denying
service to the application. The SOAP server is deployed on the remote target using the initial ports
(138, 445, and 22) and then allocates another independent port for its communications back to the
workstation where HP SUM s running. During shutdown of HP SUM, the SOAP server is shutdown
and removed from the target server, leaving the log files.
To deploy software to remote targets on their secure networks using HP SUM, the following ports are
used.
Ports Description
Port 22 This port establishes a connection to the remote Linux server using SSH.
Ports 60000-60007 Random ports are used in this range to pass messages back and forth between
the local and remote systems using SSL. These ports are used on the system
running HP SUM to send data to the target server.
Several internal processes within HP SUM automatically use the port from
60000 when no other application uses it. If a port has a conflict, the manager
uses the next available port. HP does not guarantee that the upper limit is
60007 because the limit depends on how many target devices are selected for
installation.
