Abstract
A “high availability” system comprises multiple switches under the control of one more control processors (“CPs”). Each CP performs a staged startup process when failing-over from another CP or otherwise booting up. The staged startup process involves multiple stages of processing of various executable components of the image. Some stages may depend on the prior execution of other stages. The preferred staged startup process includes the use of a staging table which permits the standby image's FSS facility to efficiently schedule the various stages of the fail-over process taking into account the inter-stage dependencies.
