Claim:
1. A method for managing host recovery operations in a computing storage environment, by a processor, comprising: providing real-time indications from a device to each of at least one of a plurality of hosts that a connected storage controller is entering a recovery operation, and further providing real-time sense data to the at least one of the plurality of hosts for presenting a real-time indication of an expected recovery timeframe; wherein providing the sense data includes pushing asynchronous notifications from the device to the at least one of the plurality of hosts; presenting the sense data by the device to the at least one of the plurality of hosts once per enabled logical path, the enabled logical paths being provided by a bitmap; providing notifications from the storage controller to the device of intermediate steps, which comprise checkpoints during a warmstart of the storage controller; and monitoring, by the device, the checkpoints provided by notification by the storage controller; wherein the checkpoints are either completed or failed by determination of a predetermined timeframe.
