Establishing a new alternate subsystem

Following a takeover, the new active subsystem runs without an alternate subsystem. You must establish a new alternate subsystem, and you can reestablish your original configuration.

Establish a new alternate subsystem by doing one of the following:

  • Establish a new alternate subsystem in the CPC that had the failed active subsystem.
  • Establish a new alternate subsystem in a different CPC without waiting for problem determination for the failed active subsystem to complete. Given a suitable configuration, this is the faster way to regain XRF capability.
    Restriction: If the XRF complex is sharing databases with another system, do not establish an alternate on a different CPC.

If you want to reestablish your original configuration (active and alternate subsystems in their original CPCs), do so in stages:

Procedure

  1. Bring up the former active subsystem as the new alternate subsystem.
  2. Perform a planned takeover.
