Defining the BIM-EPIC Environment Designing Disk Pools

Chapter 2. Installing the Basic System 2-41

Step Action

1 Obtain a VTOC listing of all potential pool volumes. For each pool, perform the

steps below.

2 Choose the pool name and write it on the Disk Pool Worksheet. Pools are

referenced by six-character names. Use a real volume serial number or any other

six-character name for a disk pool.

Write “alias” pool names on the worksheet. Using aliases helps to avoid JCL

changes. Existing JCL can reference real disk volume serial numbers, and BIM-

EPIC considers those references to be pool names. By making each volume serial

number an alias for the pool that contains the actual volume, the JCL will

automatically refer to the correct pool. An alias can also be used to easily change

a pool name once it has become established in the system.

3 Choose the disk volumes for the pool and write each volume serial number on the

worksheet.

4 When you cannot use an entire volume in a pool area, write the starting and ending

address of the space to use next to the volume serial number on the worksheet.

Remember that a specific volume can be defined only once in a given pool. If you

want to pool multiple areas on a volume, you must place each area on that volume

in a separate pool.
