This section describes items that should be considered before you install HLASM Toolkit Feature.

• VMSES/E is required to install and service this product.
• If multiple users install and maintain licensed products on your system there might be a problem getting the necessary write access to MAINT's 51D disk. If you find that there is contention for write access to the 51D disk, you can eliminate it by converting the software inventory from minidisk to the Shared File System (SFS). See z/VM: VMSES/E Introduction and Reference for information about how to make this change.
• HLASM Toolkit Feature is installed and serviced using the user ID P696234K. IBM recommends that you use this userid, however, you can change the userid name if you wish. If you change this name, you must create a PPF override. Generally this section of this installation and customization guide assumes that you have used the IBM-recommended userid, P696234K.
• If you plan to change the userid, it might be easier to do so during Step 1, substep 6, while you are installing the product.
