How to Find the LPAR Number on the AS/400

IBM originally introduced the AS/400 processor family in 1988 and rebranded the system as the iSeries in 2000. One of the biggest enhancements to these newer model processors is that they allow IT managers to logically partition the system's hardware resources into multiple computing environments, each of which is termed an LPAR (Logical PARtition). Each LPAR is assigned a separate system name and partition number. Working with any of the partitions is accomplished using HMC (Hardware Maintenance Console).

Things You'll Need

• HMC console profile and password

Instructions

1. Sign on to the HMC by entering the console profile and password. Press the "Enter" key. The "Hardware Maintenance Console" primary panel will display.

2. Click on the System Management option located in the Navigation Area dropdown menu on the left side of the panel (screen). This will open the Server and Partition Server Management dropdown menu.

3. Expand the Partitions folder, select the partition you wish to work with and right click on the partition system name. A pop-up menu will immediately display listing several functions and options which may be performed.

4. Click on the "Properties" option. The General (default) tab of the Partition Properties panel will be displayed.

5. Check the information in the "ID" field. The number displayed there is the LPAR identification number.

Tips & Warnings

• Operating the HMC requires specific training and should never be attempted by inexperienced personnel.
