Use the information
listed in Table 5-4 to ensure that your system meets all requirements. Your system
must meet all requirements in order for an upgrade to be successful.
Table 5-4 Upgrade Readiness Criteria
| Component | Requirement |
|---|
| Version of HP XC System Software currently
installed on the system | The current HP XC system
must be running HP XC System Software Version 3.0, Version 3.1 ADK, or Version
3.1. |
| Firmware | The firmware versions installed on all system
components have been updated according to the Version 3.2 master
firmware list: http://www.docs.hp.com/en/linuxhpc.html |
| Distribution media | You must have in your possession the HP XC System Software Version 3.2 DVD
that is appropriate for the cluster platform architecture. |
Notify users in advance that
a software upgrade is planned. Because you must shut down all nodes,
plan the upgrade for a time when system activity is at its lightest.
Use your preferred backup
solution to perform a full backup of the head node, which can be done
while the head node is up and when jobs are running. If the /hptc_cluster file system is located on an HP SFS server,
ensure you back up the SFS server as well.
It can be beneficial to have online access to the contents of the /etc, /opt/hptc, and /hptc_cluster directories after the upgrade in case you need to look at previous
configuration files for configuration information.
If the upgrade is not successful, you might have
to revert to the previously installed release.
If you are using LSF,
make sure that you save the LSF /hptc_cluster/lsf/conf/ configuration directory. Also save any other known LSF customizations,
such as elim scripts.
If the system is using HP
StorageWorks Scalable File Share, see the SFS documentation to determine
if you are required to update the SFS server and client software for
the new HP XC release. If an SFS software update is required,
you perform that task in “Task 6: Install Patches and Reinstall Additional Software” .
If the system is configured
with an InfiniBand interconnect, upgrade the HCA cards on all nodes
now.
Determine whether to configure
improved availability of services. Improved availability of services
is a new feature introduced in HP XC System Software Version 3.1.
See “Task 9: Plan a Service Availability Strategy”, which describes what improved availability
offers, how it is achieved, the supported availability tools, and
the services that are eligible for improved availability.
Read the Version 3.2 HP XC System Software Release Notes before
beginning the upgrade procedure. The release notes describe any last-minute
changes to software, firmware, or hardware that might affect the upgrade
process.
The HP XC System Software Release Notes for each HP XC software
release are available online:
