Updating RSCT packages for PowerVM NovaLink
Resource Monitoring Control (RMC) connections between PowerVM® NovaLink and each logical partition are routed through a dedicated internal virtual network. For easier configuration of the internal virtual network, assign an IPv6 link-local address to the RMC virtual network interfaces. To assign IPv6 link-local addresses to the RMC virtual network interfaces on AIX® and Linux logical partitions, the Reliable Scalable Cluster Technology (RSCT) packages must be at version 3.2.1.0 or later.
RSCT packages at version 3.2.1.0 support an IPv6 Link Local addressed virtual Ethernet adapter on each AIX and Linux logical partition. The AIX or Linux logical partition uses the virtual Ethernet adapter to connect to the PowerVM NovaLink partition through a virtual switch (which is called MGMTSWITCH). The virtual switch is configured to communicate only with the trunk port. An AIX or Linux logical partition can use this virtual network only to connect with the PowerVM NovaLink partition. AIX or Linux logical partitions can connect with partitions other than the PowerVM NovaLink partition only if you configure a separate network for this purpose.
pvmctl eth list | grep -e MAC -e MGMTSWITCH
You can refer to the IP
configuration of the RMC virtual Ethernet interface on the PowerVM
NovaLink logical partition to configure the IP address of the
RMC virtual Ethernet interface on other logical partitions.- For more information about how to verify the version of RSCT packages on AIX logical partitions and how to update RSCT packages from the AIX installation media, see Verifying RSCT installation on AIX nodes.
- For more information about how to install or update the RSCT packages, see Verifying RSCT installation on Linux nodes.
- For logical partitions that run Ubuntu, you can obtain the RSCT packages from the following APT repository: https://launchpad.net/~ibmpackages/+archive/ubuntu/rsct.
- For RHEL based partitions, you can obtain the RSCT packages by enabling the YUM
ibm-power-repo repository by completing the following steps:
- Run the following command to obtain RPM files from
RSCT:
rpm -vih --nodeps http://public.dhe.ibm.com/software/server/POWER/Linux/yum/download/ ibm-power-repo-latest.noarch.rpm
- Run the following command and accept the license statement to set up the repository:
/opt/ibm/lop/configure
- Run the following command to obtain RPM files from
RSCT:
You must install the DynamicRM package to enable DLPAR and Mobility operations.
systemctl restart pvm-rest.service
