Granting reservation for access to a storage drive

A multi-host storage system comprising

• a memory;
• a storage controller, communicatively coupled to the memory, to:
• receive, from a first host controller of the multi-host storage system, a first reservation command to acquire access to a storage drive that is shared to a second host controller of the multi-host storage system, the reservation command comprising a first host identifier to identify the first host controller;
• modify the first reservation command by replacing the first host identifier with a first range identifier that is associated with the first host controller and that identifies a first range of storage of the storage drive;
• and
• send the modified first reservation command comprising the first range identifier to a drive controller of the storage drive.

A non-transitory computer-readable medium comprising instructions that, when executed by a multi-host storage system, cause the multi-host storage system to:

• receive, by a storage drive of the multi-host storage system, a modified first submission queue command comprising a first range identifier, the modified first submission queue command generated by replacing a first host identifier with the first range identifier;
• responsive to receiving the modified first submission queue command, identify, by the storage drive, a first range of storage based on the first range identifier of the modified submission queue command;
• and
• grant, by the storage drive, a reservation for access to the storage drive on behalf of the first host controller by associating the reservation for the first range with a second range of storage.
