The LPAR tool allows the administration of any number of LPARs, managed systems and HMCs from one central system (AIX or Linux). The software can be installed as a package and is available immediately. The current version of the LPAR tool can be downloaded from our download area https://powercampus.de/en/download-2. It includes a test license for up to 10 HMCs, 100 managed systems and 1000 LPARs.
Status and configuration of LPARs are regularly needed information in the administration of LPARs. With the LPAR tool, information such as status, RMC status, number of cores, size of RAM, OS version and other data can be easily and quickly determined, even with hundreds or thousands of LPARs. Which LPARs do not have an RMC connection is shown in one of the examples.
A frequent question in larger environments (multiple HMCs, many managed systems) is: which are the HMC(s) and managed system of an LPAR. This question can easily be answered with the LPAR tool, for which there is the command “lpar show“.
How to start a console for an LPAR with the LPAR tool.
The LPAR tool can manage virtual networks (vnetwork). The article shows how to give vnetworks a meaningful name. In addition, it shows how you can search for vnetworks or VLANs in a simple way.
Creating and deleting virtual networks is done automatically by the HMC. As soon as a virtual Ethernet adapter with a new VLAN ID is created, the HMC generates the corresponding vnetwork with a standard name. When the last virtual Ethernet adapter for a VLAN is deleted, the HMC automatically deletes the associated vnetwork. But virtual networks can also be created and deleted manually.
With the LPAR Tool, SEA statistics can be displayed at any time with the command “vios seastat“. This allows you to determine at any time which client LPARs have which network throughput.
