Abstract
A lower level processor holds a link, in response to detecting a link down condition of the link. In response to the holding of the link, the lower level processor transmits a command to an upper level processor indicating the link down condition of the link. The lower level processor initiates a process of link recovery for the link, in response to receiving an authorization from the upper level processor.
