3.5 Installing Patches or RPM Updates

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.

You are required to download and install all available patches and updated RPM packages now

before the system is configured so that the software updates are propagated to all nodes during

the initial image synchronization.

See the following sources to determine if additional software packages (patches) are available

for this release:

• The HP IT Resource Center (ITRC) website:

http://www.itrc.hp.com/

Section 3.5.1 (page 60) describes how to download HP XC patches from this website, if they

are available.

• The HP XC System Software Release Notes for Version 4.0

Because the HP XC System Software Release Notes are updated periodically, they are only

available on line:
