10.1 Sources for Software Packages and Information
For each supported version of the HP XC System Software, HP releases all Linux security updates
and HP XC software patches on the HP IT Resource Center (ITRC) website.
Software patches might also be available for other HP products that you are installing, such as
SVA, RGS, or Serviceguard. To determine if software patches are available, go to the
product-specific location on the ITRC.
See the following sources to determine if additional software packages (patches) are available
for this release of the HP XC System Software:
The ITRC website:
http://www.itrc.hp.com/
“Downloading and Installing Patches” describes how to download HP XC patches from
this web address, if they are available.
The HP XC System Software Release Notes for Version 4.0

10.2 Digital Signature
All HP XC software packages developed by HP are digitally signed to ensure HP XC software
integrity and authenticity.
HP provides a public key with the HP XC DVD. You can use this key to verify the integrity and
authenticity of an HP software package delivered by either on the DVD or through ITRC.
The file named RPM-GPG-KEY file in the root directory of HP XC DVD contains the public key.
IMPORTANT: You must import the public key manually from the DVD after setting up the HP
XC cluster; this is a one time task.
Use the following command to import the public key:
# rpm import path_key_file
In this case, the path_key_file is /dvd_mount_point/RPM-GPG-KEY.
To verify that whether or not an RPM is signed, use the following command:
# rpm -v --checksig --nodigest package_name.rpm
package_name.rpm
Header V3 DSA signature: OK, key ID d7265960
V3 DSA signature: OK, key ID d7265960
In the output shown, the term OK indicates that the RPM is signed and thus confirms the integrity
of the HP XC software package.
