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.
