Abstract:
Example methods are provided to perform persistent reservation emulation in a shared virtual storage environment that includes a first host supporting a first node and a second host supporting a second node. One example method may comprise detecting a command issued by a first node to command issued by a first node to update information relating to a reservation or registration associated with a virtual disk, and updating persistent reservation information associated with the virtual disk to indicate that the command has been issued by the first node. The method may also comprise determining that the second node either has acknowledged the updated persistent reservation information, or has not acknowledged the updated persistent reservation information within a time interval. The method may further comprise updating the persistent reservation information based on the command.

Claim (Index 8):
A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a first host, cause the processor to perform a method of persistent reservation emulation in a shared virtual storage environment that includes the first host supporting a first node and a second host supporting a second node, wherein the method comprises:\n detecting a command issued by the first node to update information relating to a reservation or registration associated with a virtual disk, wherein the virtual disk that is stored on a physical storage system and accessible by the first node and the second node; updating persistent reservation information associated with the virtual disk to indicate that the command has been issued by the first node, wherein the persistent information is accessible by the first host and the second host; determining that the second node either has acknowledged the updated persistent reservation information, or has not acknowledged the updated persistent reservation information within a time interval; and updating the persistent reservation information based on the command.
