Disk Space Requirements

CA CSM has the following disk space requirements:

Note: All space allocations are described for 3390 DASD.

• For the installation and setup of CA CSM:
  • Hierarchical File System (HFS) or zSeries File System (zFS) space = 680 cylinders

    Note: We recommend using zFS file systems. For information about how to migrate from HFS file systems to zFS file systems, see the latest IBM z/OS Migration guide.

    Important! Starting from z/OS V2.1, IBM has changed the way the utility program IOEAGFMT (zFS data set formatter) functions. The utility requires the zFS kernel address space to be active before any execution of IOEAGFMT is allowed. If you use zFS file systems at your site, you must ensure that zFS kernel address space is active. For more information, see the IBM z/OS Distributed File Services zFS Administration.

  • z/OS space = 678 cylinders

    This space contains the CA Datacom/MSM SMP/E environment and runtime libraries. The SMP/E environment contains the CA Datacom/MSM, [assign the DSV variable value for your book], and CA CSM components.

  • A TSO region = 143360 KB (at minimum)
  • SDS root space = 100 tracks (approximately)

    For the Software Deployment Service (SDS), the aggregated amount of DASD space for the initial DASD setup is 100 tracks. This amount includes CA CSM and SDS space on the CA CSM host only, and does not include space for the deployment snapshot file system. Additional space is needed for the SDS target system.

  • SDS deployment space = 500 cylinders

    For the SDS, each target system needs 500 cylinders of 3390, except CA Database Management Solutions for DB2 for z/OS, which needs 1500 cylinders.

• For the operation of CA CSM:

  After initial setup, CA CSM allocates additional HFS or zFS files depending on the download of products and maintenance. The amount of space that is allocated varies depending on the number of products and maintenance, and the size of any associated files.
