Abstract
Embodiments of the present disclosure provide systems and methods for implementing enhanced Device Control Block (DCB) scan recovery for channel recovery actions. A disclosed method comprises identifying channels to be recovered and creating a DCB bit array reflecting each DCB to be scanned for the set of the channels to be recovered by a system assist processor. The system assist processor performs asynchronous channel communication area (CCA) recovery processing, starts synchronous DCB scan recovery, and sequentially processes an incremental portion of the DCB bit array interleaved with asynchronous CCA recovery processing. The system assist processor completes asynchronous CCA recovery processing and synchronous DCB scan recovery to complete channel recovery of the set of channels. The system assist processor starts each channel of the set of channels responsive to completing channel recovery processing for each channel.
