Changing Scratch Pool Information

You can define scratch pools only once for each initialization of the HSC. If it is necessary to change CA VM:Tape scratch pool information, you must:

  1. Change the CA VM:Tape scratch pool definition and assignment files.

    Note: If you define your scratch pools in the HSC configuration file, you must make the corresponding updates to that file also.

  2. Synchronize the CA VM:Tape scratch pools with the HSC scratch pools by issuing the CA VM:Tape REFRESH POOL command, or end and restart CA VM:Tape.
  3. End and restart the HSC service virtual machine to enable CA VM:Tape to communicate the new pool definitions to the HSC.

    If you do not reinitialize the HSC service virtual machine, the CA VM:Tape interface to HSC remains started but the new scratch pool definitions are not conveyed to HSC. This situation can cause unpredictable results when scratch mount requests are satisfied.
