A software license is required to use the LPAR tool. To make testing the LPAR tool as easy as possible, the LPAR tool includes a test license. The test license is typically valid for a few months.

Whether a valid license is present or not can be checked relatively easily as follows:

$ hmc -L
ERROR: license expired since 30.09.2021
$

In this case there is no valid license.

Here is an example in case a valid license is available:

$ hmc –L
LicenseId: 4
LicenseVersion: 1
LicenseType: test
Customer: none
HmcCount: 10
MsCount: 100
LparCount: 1000
ExpirationDate: 30.09.2022
LicenseKey: e9b1d1159514af19b8f25f24d08b0f16
$

The example output shows that this is a test license (LicenseType: test). The license is valid until September 30, 2022 (ExpirationDate: September 30, 2022).

If no valid license is available, a license for evaluation purposes can be requested info@powercampus.de. However, the internal test license of the latest version of the LPAR tool should usually be valid!

If a commercial license has been purchased, it can be entered in /opt/pwrcmps/etc/lpar.lic. In this case, the LPAR tool can be used by all users. A license can also be entered in the ~/.lpar.lic file in a user’s home directory. The LPAR tool can then only be used by that user.
