HP Smart Update Manager 6.4.1 Release Notes

Prerequisites for using Linux and HP-UX root credentials
If you run HP SUM from a Linux system where you have not logged into the system as a root user, you
can still update nodes if you use sudo or super user Access level options.
• If you have run HP SUM as a root user, remove the temp directory created by HP SUM.
• Make sure you have read/write access permissions to the /tmp and /var directories.
• If you create a sudo user, make sure that you add that user to the /etc/sudoers file. The
following table shows the privileges and specifications for users.
SpecificationPrivilegeUser
ALLALL= (ALL)Root
ALLALL= (ALL)Sudo_user
• Edit the entry in the /etc/sudoers file so the system asks for the sudo user password instead
of root user password when you run the sudo command.
The following table shows the privileges to comment or remove from /etc/sudoers.
SpecificationPrivilegeUser
ALLALL= (ALL)All
This often occurs in SUSE Linux systems.
#Defaults targetpw # ask for the password of the target user.
WARNING! Only use this option with Defaults targetpw.
• To use super user functionality, configure the user as a super user with all root privileges. You
can also use non-root user with a root user to update components.
Network ports used by HP SUM
HP SUM requires that certain network ports are available for proper operation. If you lock down
network ports, make sure that the ports listed in the network port tables are open so that HP SUM
works correctly when connecting to remote node servers and hosts. If you are unable to unlock these
network ports, you must run HP SUM locally and update network-based hosts, such as the OA, iLO,
and VC modules, through their web interfaces.
NOTE: Use the open_firewall parameter for HP SUM to automatically open the required firewall
ports on the local host and any remote Linux servers.
Updates for most node types require network traffic in both directions between the server running HP
SUM and the node. The server running HP SUM creates a local HTTP server, which is used to serve
firmware binaries to the node and to communicate node status. The remote node issues HTTP requests
and posts status updates to the server running HP SUM during the update process. If there is a routing
problem or firewall blocking traffic back from the remote node to the system running HP SUM, firmware
updates might be blocked, status updates blocked or delayed, or both.
