Use the information
listed in Table 5-4 to ensure that your system meets all requirements. Your system
must meet all requirements for an upgrade to be successful.
Table 5-4 Upgrade Readiness Criteria
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 HP SFS documentation to
upgrade the HP SFS server and client software for the new HP XC release,
or contact your local HP SFS support center. Perform the SFS server
upgrade first, then perform the HP XC cluster upgrade.

|
 | IMPORTANT: Complete the HP SFS 2.2–1 upgrade before proceeding with
the HP XC 3.2.1 upgrade, especially when the /hptc_cluster directory is an HP SFS file system. |
|
| |
|
Verify the InfiniBand software stack used on the SFS cluster
before proceeding with the HP XC software upgrade.
Connect to the HP SFS Admin server as root and run the sfsmgr command.
If you want to check the configuration of the HP SFS file
system called hptc_cluster, run the following
command:
sfs> show filesystem hptc_cluster
...
Interconnect: o2ib
... |
In the above example, the field Interconnect shows the interconnect used.
If the system is configured
with an InfiniBand interconnect, verify that all HCA cards are running
the minimum required firmware listed in the Version 3.2.1 master firmware
list:
http://www.docs.hp.com/en/linuxhpc.html
The InfiniBand firmware binary files are included in the HP
SFS 2.2–1 software and are automatically installed on all SFS
nodes. However, the firmware on the HCA adapter must be upgraded manually,
using these firmware binary files.
If you need assistance with identifying and upgrading the firmware
on the InfiniBand switches and HCA adapters, contact your local HP
support center.
If the system is not configured
with improved availability of services, determine whether you want
to configure that feature. Improving the availability of services
is a feature that was 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 3.2.1 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:

Visualization Array, V2.1.1 Release Notes before
beginning the upgrade procedure. Upgrade and reinstall procedures
