HP XC System Software Release Notes for Version 3.1

If you want to use the Voltaire MPI tools, you can work around this issue by adding
/usr/voltaire/mpi/bin to the PATH in the /etc/profile file, similar to the following:
# Voltaire InfiniBand Stack Services - Start
PATH="${PATH}:/usr/voltaire/bin:/usr/voltaire/scripts:/usr/mellanox/bin:\
/usr/voltaire/mpi/bin"
export MTHOME="/usr/mellanox"
export NOGAMLA=1
export MTCONF=release
# Voltaire InfiniBand Stack Services - End
6.2.8 Invoke the cluster_config Utility From the Console
It is possible for an external Ethernet connection to occasionally fail to come up after invoking
the cluster_config --init | --migrate command. You may see messages similar to
the following in the /var/log/nconfig.log file:
Bringing up interface eth2: SIOCSIFFLAGS: Cannot allocate
memory Failed to bring up eth2.
If the output from the ifconfig command does not contain the external interface, invoke the
ifup command. In the following example, external_device_name is the name of an external device
such as eth2.
# ifup external_device_name
Because this issue is intermittent, HP recommends that you invoke the cluster_config utility
directly from the console (and not remotely) in case you lose the external connection.
6.2.9 HP Integrity System Does Not Boot After an Upgrade
If an HP Integrity system does not boot after a software upgrade, select the option to boot HPC
Linux, and at the boot prompt, boot the system to single-user mode as follows:
> linux single
Then, edit the elilo.conf file as described in “Required Task on HP Integrity Head Nodes:
Edit the elilo.conf File” (page 52) , and boot the system to multiuser mode.
