Abstract
Serial number based storage device allocation is disclosed. A serial number associated with the storage device is mapped to a device file associated with the storage device on a host having a connection to the storage device. The serial number is mapped to a device address by which the storage device is known to a library with which the storage device is associated. A request requiring that an available storage device be allocated to service the request is received. The storage device is allocated, based at least in part on the serial number to device file and serial number to device address mappings, to service the request.
Claims23
A method of allocating a storage device, comprising:
- mapping a serial number associated with the storage device to a device file associated with the storage device on a host having a connection to the storage device;
- mapping the serial number to a device address by which the storage device is known to a library with which the storage device is associated;
- receiving a request requiring that an available storage device be allocated to service the request;
- and
- allocating the storage device, based at least in part on the serial number to device file and serial number to device address mappings, to service the request.
A system for allocating a storage device, comprising:
- a processor configured to:
- map a serial number associated with the storage device to a device file associated with the storage device on a host having a connection to the storage device;
- map the serial number to a device address by which the storage device is known to a library with which the storage device is associated;
- and
- a communication interface configured to receive a request requiring that an available storage device be allocated to service the request;
- wherein the processor is further configured to allocate the storage device, based at least in part on the serial number to device file and serial number to device address mappings, to service the request.
A computer program product for allocating a storage device, the computer program product being embodied in a computer readable medium and comprising computer instructions for:
- mapping a serial number associated with the storage device to a device file associated with the storage device on a host having a connection to the storage device;
- mapping the serial number to a device address by which the storage device is known to a library with which the storage device is associated;
- receiving a request requiring that an available storage device be allocated to service the request;
- and
- allocating the storage device, based at least in part on the serial number to device file and serial number to device address mappings, to service the request.
