Handling hibernation of a process on a storage device

A non-transitory computer-readable medium storing software that, when executed by at least one processor, handles hibernation of a process, the software comprising:

• executable code that freezes paths to a storage device corresponding to the process, wherein freezing the paths prevents performing new input/output (I/O) operations using the paths while allowing performance of prior I/O operations using the paths, the prior I/O operations being initiated prior to the freezing of the paths;
• executable code that, after performing the prior I/O operations using the paths, suspends the process;
• and
• executable code that, after suspending the process, obtains a snapshot, the snapshot including at least metadata for the process;
• executable code that, after obtaining the snapshot, restores the snapshot and then resumes the process;
• executable code that determines from among the paths a first path to the storage device from an active host and a second path to the storage device from a passive host;
• and
• executable code that thaws the first path and maintains the second path for at least some time as a frozen path, wherein, after thawing the first path, the first path is provided in a reserved state allowing I/O operations between the active host and the storage device, and wherein the second path, being still frozen, is provided in a blocked state preventing I/O operations between the passive host and the storage device, wherein the first path is thawed according to at least one of:
• (i) prior to resuming the process;
• or
• (ii) after resuming the process.
