Examples of how RESTORE affects DCs and GCLs

To understand how 

iCap

 responds to the RESTORE parameter options, assume that the following conditions exist:

  • Policy A (the active policy) contains SYSA, SYSB, and SYSC.
  • Policy B contains SYSA and SYSB.
  • RESTORE=YES is set in the master PAS JCL.
Example

Switching the active policy from Policy A to Policy B produces the following results:

  • iCap restores only groups or LPARs that existed in Policy A but not in Policy B.

    Consequently, switching the policy causes iCap to restore only SYSC.

  • SYSA and SYSB (common to both the old policy and the new) remain at their current value. They are not restored until iCap stops managing them, or the master PAS terminates.
Example

As another example, assume that the same initial conditions exist regarding Policy A, Policy B, and RESTORE=YES; however, you use a MODIFY command to change the RESTORE parameter to NO while the master PAS is running. Switching the active policy from Policy A to Policy B produces the following results:

  • SYSC is not restored (meaning the DCs and GCLs do not change).

If the master PAS terminates or iCap switches from manage mode, results are as follows:

  • If RESTORE=NO, SYSA and SYSB are not restored. When you restart the master PAS, iCap uses the DC and GCL values that existed when the PAS terminated; the original values for SYSA and SYSB are lost.
  • If you change back to RESTORE=YES (before the PAS terminates), SYSA and SYSB are restored, but SYSC does not change.
