DASD storage required
Before you install, understand the user ID and DASD storage requirements. Some important points
to consider are:
- The installation user ID and minidisks or SFS are defined in Step 2: Allocate resources for installing High Level Assembler. Table 1 gives an estimate of the storage that is required to install High Level Assembler for z/VM®.
- P696234J is the default user ID and can be changed. If you choose to change the name, you need to create a Product Parameter File (PPF) override to change the name. This can be done in Step 1, substep 6.
- If you choose to install High Level Assembler on a common user ID, the default minidisk addresses for High Level Assembler might already be defined. If any of the default minidisks that are required by High Level Assembler are already in use, create an override to change the minidisks for High Level Assembler so they are unique.

If you
plan to use SFS directories, then calculate the number of 4K blocks that are required from Table 1.
