HP XC System Software Release Notes for Version 3.1
6 Software Upgrades
This chapter contains notes about upgrading the HP XC System Software from a previous release
to this release.
Installation release notes described in Chapter 4 (page 37) and system configuration release
notes described in Chapter 5 (page 39) also apply when you upgrade the HP XC System Software
from a previous release to this release. Therefore, when performing an upgrade, make sure you
also read and follow the instructions in those chapters.
Go to the following sections depending upon the type of upgrade you are about to perform; see
Table 1-1 (page 23) for upgrade type definitions.
• “Notes That Are Common to Both Upgrade Types” (page 49)
• “Notes That Apply to Major Upgrades” (page 51)
• “Notes That Apply to Minor Upgrades” (page 53)
6.1 Notes That Are Common to Both Upgrade Types
The notes in this section apply to both upgrade types: major and minor.
6.1.1 Upgrade Does Not Require All Patches For Current Release
The upgrade chapter in the HP XC System Software Installation Guide (Task 1: Prepare for the
Upgrade) recommends that you install all relevant patch kits for the current release before
upgrading to Version 3.1. This step is not required.
6.1.2 Save the LSF Configuration and Customizations Before Upgrading
Before upgrading the current system, save the LSF /hptc_cluster/lsf/conf/configuration
directory. Also save any other known LSF customizations, such as elim scripts.
Compare the Final LSF configuration After the cluster_config portion of the upgrade has
completed, compare the final LSF configuration with the saved version to ensure that only the
appropriate changes relevant to the upgrade have occurred. Also ensure (or restore, if required)
the elim scripts. HP recommends that you use another terminal window to install the elim
scripts at the point when the cluster_config utility displays the following prompt:
All user specified configuration is complete.
The Golden Image will be created next.
[P]roceed, [Q]uit:
Thus, changes to the /opt/hptc/lsf/top/6.2/ directory will be included in the golden
image. This is the directory where elim scripts are expected to reside.
Any changes to the LSF configuration files in the /hptc_cluster/lsf/conf/ directory can
occur after cluster_config has finished because this directory is not part of the golden image.
If the LSF version has changed, binary paths (including the $LSF_SERVERDIR directory, where
elim scripts are expected to reside) have also changed.
6.1.3 Possible Failed RPM Dependencies Errors Seen During the preupgradesys
Utility
The preupgradesys utility might report failed dependencies errors when it is trying to remove
Myrinet, InfiniBand, and QsNet
II
interconnect RPMs. To work around this problem, you must
manually remove the appropriate RPM.
Myrinet
Remove the gm RPM if you see a message similar to the following:
