A valid license is required to use the LPAR-Tool.

To make testing the LPAR-Tool as easy as possible, the versions of the LPAR-Tool available for download contain a time-limited test license. This test license allows the use of the LPAR-Tool for the purpose of evaluating the tool. This excludes temporary productive use.

To use the LPAR-Tool productively, a regular license is required. The conditions and costs for such a regular license can be requested by mail to info@powercampus.de.

Using the “-L” option, each of the 4 LPAR-Tool commands can be used to check whether a valid license is available:

$ hmc -L
LicenseId: 4
LicenseVersion: 1
LicenseType: test
Customer: none
LparCount: 1000
MsCount: 100
HmcCount: 10
ExpirationDate: 31.03.2024
LicenseKey: 473843cc5f7c7c058de63f6c0ec31acf
$

The example output shows an integrated test license, which is valid until March 31, 2024. It supports up to 10 HMCs, up to 100 managed systems and up to 1000 LPARs.

If the integrated test license is still valid, then no license needs to be requested to evaluate the LPAR-Tool. You can just start your tests!

If there is no valid license, the following message is displayed:

$ hmc -L
ERROR: license expired since 30.09.2023
$ 

The expiration date of the built-in test license or the existing regular license is displayed.

If the integrated test license is no longer valid and you still want to test the LPAR-Tool, you can request a test license by email (to info@powercampus.de).

If you have requested and received a test license, or you have purchased a regular license, it must be saved on the system or systems on which the LPAR-Tool is to be used.

If a regular license was purchased or the LPAR-Tool is to be tested by several users, then the license should be entered in the file /opt/pwrcmps/etc/lpar.lic:

$ cat /opt/pwrcmps/etc/lpar.lic
LicenseId: 4
LicenseVersion: 1
LicenseType: test
Customer: none
LparCount: 1000
MsCount: 100
HmcCount: 10
ExpirationDate: 31.03.2024
LicenseKey: 473843cc5f7c7c058de63f6c0ec31acf
$

(In the example, the integrated test license was entered in the file /opt/pwrcmps/etc/lpar.lic.)

If the LPAR-Tool is only used by one user, then the license can also be entered in the .lpar.lic file in the user’s home directory:

$ cat ~/.lpar.lic
LicenseId: 1009
LicenseVersion: 1
LicenseType: fixed
Customer: TheCompany
LparCount: 200
HMCs: 12A3B4C,56D7E8F
HMCs: 1234567,ABCDEFG
ExpirationDate: 28.02.2024
LicenseKey: 90ab715fcc1930ae469b7cfe617578cd
$

After a license has been saved in one of the files mentioned, the validity of the license should be checked (especially to exclude typos):

$ hmc -L
LicenseId: 1009
LicenseVersion: 1
LicenseType: fixed
Customer: TheCompany
LparCount: 200
MsCount: 
HmcCount: 
ExpirationDate: 28.02.2024
HMC: 1234567
HMC: 12A3B4C
HMC: 56D7E8F
HMC: ABCDEFG
