Abstract: A technique for operating a high-availability (HA) data processing system includes, in response to receiving an HA logout indication at a cache, initiating a walk of the cache to locate cache lines in the cache that include HA data. In response to determining that a cache line includes HA data, an address of the cache line is logged in a first portion of a buffer in the cache. In response to the first portion of the buffer reaching a determined fill level, contents of the first portion of the buffer are logged to another memory. In response to all cache lines in the cache being walked, the cache walk is terminated.

Abstract: A technique for operating a data processing system includes determining whether a cache line that is to be victimized from a cache includes high availability (HA) data that has not been logged. In response determining that the cache line that is to be victimized from the cache includes HA data that has not been logged, an address for the HA data is written to an HA dirty address data structure, e.g., a dirty address table (DAT), in a first memory via a first non-blocking channel. The cache line that is victimized from the cache is written to a second memory via a second non-blocking channel.
