HP XC System Software Installation Guide Version 4.0

Table 9-4 Upgrade Readiness Criteria
RequirementComponent
Your current HP XC system must be running HP XC System
Software Version 3.2 or Version 3.2.1.
Version of HP XC System Software
currently installed on the system
The firmware versions installed on all system components have
been updated according to the HP XC Version 4.0 Master Firmware

IMPORTANT: If your HP XC configuration has one or more
supported generations of ProLiant DL145 servers in the hardware
configuration, you must upgrade the BMC firmware to version
1.25A after the upgrade to HP XC System Software Version 4.0 is
complete.
Firmware
You must have in your possession the HP XC System Software
Version 4.0 DVD that is appropriate for the cluster platform
architecture.
Distribution media
2. 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 low.
3. 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 Scalable File Share (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.
4. 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.
5. If the system is using SFS, see the SFS documentation to upgrade the SFS server and client
software that is compatible with the new HP XC release, or contact your local SFS support
center. Perform the SFS server upgrade first, then perform the HP XC upgrade.
IMPORTANT: Completing the SFS upgrade before proceeding with the HP XC upgrade is
especially important when the /hptc_cluster directory is an SFS file system.
Verify the InfiniBand software stack used on the SFS cluster before proceeding with the HP
XC software upgrade.
a. Connect to the SFS administration server as root and run the sfsmgr command.
b. If you are using an InfiniBand interconnect, run the following command to verify the
configuration of the SFS file system called hptc_cluster.
sfs> show filesystem hptc_cluster
...
Interconnect: o2ib
...
In the previous example, the Interconnect field shows the interconnect used.
6. If the system is configured with an InfiniBand interconnect, verify that all HCA cards are
running the minimum required firmware listed in the HP XC Version 4.0 Master Firmware
