HP XC System Software Release Notes for Version 3.1

1. Run the following device_config command to set the external device MAC address in
the database for a specific node. Use the MAC addresses you obtained in “Required Task:
Determine MAC Addresses For Client Nodes With External Devices”.
# cd /opt/hptc/config/sbin
# ./device_config --type E MAC_address --host host_name
2. Run a similar device_config command for every node that has an external connection.
3. Verify that the MAC addresses have been populated in the database:
# shownode config | grep -A 3 External:
6.2.4 Required Task: Remove SystemImager Override Symbolic Links Before Running
the cluster_config Utility
Because the master autoinstallation scripts (named *.master.0) have changed in this release,
you must remove the symbolic links in the /var/lib/systemimager/scripts directory
before invoking the cluster_config --init | --migrate command. After you do so,
the cluster_config utility automatically creates the correct symbolic links.
If you are using file overrides to the golden image, you must also re-create the *.master.0
override file or files so that the file or files use the new version of the master autoinstallation
script.
Re-create the *.master.0 override files and associated symbolic links after invoking the
cluster_config utility (but before re-imaging) because the new autoinstallation script is not
created until after cluster_config is invoked.
6.2.5 Required Task on HP Integrity Head Nodes: Edit the elilo.conf File
If the head node is an HP Integrity model server, perform this task on the head node after you
upgrade and reboot the head node:
1. Use the text editor of your choice to edit the following file:
/boot/efi/efi/lnxhpc/elilo.conf
2. Make the following changes to the line that begins with the word kernel:
• Remove rhgb
• Remove quiet
3. Save your changes and exit the text editor.
4. Reboot the head node.
6.2.6 Required Task for HP Integrity Hardware: Set the IPMI Password
After you upgrade the system, follow the instructions in the HP XC System Software Administration
Guide to set the IPMI password on HP Integrity hardware models.
6.2.7 InfiniBand Directory is Missing from the /etc/profile File
The following note applies only to systems using an InfiniBand interconnect.
The ibhost-biz RPM adds InfiniBand directories to the PATH variable in the /etc/profile
file. When you remove or upgrade the previous ibhost-biz RPM, the RPM does not undo the
/etc/profile changes, nor does it modify the file since it changed from HP XC Version 2.1 to
Version 3.1.
This is not critical because HP does not recommend using Voltaire MPI, which is located in
/usr/voltaire/mpi/bin/mpicc. However, these tools are available for diagnostic purposes,
and you might want to use them.
For proper HP-MPI behavior, HP recommends that you module load hp/mpi/default,
which sets up mpicc and mpirun as the HP-MPI versions.
