Emulating a stretched storage device using a shared storage device

A non-transitory computer-readable medium storing instructions, which when executed by a processing device, cause the processing device to perform a method comprising:

• receiving a device discovery command from a recovery manager running on a management server within a first or second datacenter;
• requesting, in response to the device discovery command, device identifiers for one or more logical storage devices within the first datacenter;
• receiving, in response to the request, a device discovery response including a first device identifier for a first logical storage device within the first datacenter;
• modifying the received device discovery response to include the first device identifier as the identifier for both the first logical storage device and as an identifier for a peer logical storage device to emulate the peer logical storage device as being actively available within the second datacenter;
• and
• returning the modified response to the recovery manager in response to the device discovery command.

An apparatus comprising:

• a processing device;
• and
• a memory coupled to the processing device, the memory storing instructions which, when executed by the processing device, cause the apparatus to:
• receive a device discovery command from a recovery manager running on a management server within a first or second datacenter;
• request, in response to the device discovery command, device identifiers for one or more logical storage devices within the first datacenter;
• receive, in response to the request, a device discovery response including a first device identifier for a first logical storage device within the first datacenter;
• modify the received device discovery response to include the first device identifier as the identifier for both the first logical storage device and as an identifier for a peer logical storage device to emulate the peer logical storage device as being actively available within the second datacenter;
• and
• return the modified response to the recovery manager in response to the device discovery command.
