Fiber channel connection storage controller

A storage system adapted to be coupled to a plurality of host devices via a fibre channel, the storage system comprising:

• a plurality of storage devices;
• a storage control device that stores data sent from said plurality of host devices to a plurality of storage regions provided by said plurality of storage devices into said plurality of storage devices;
• and
• an input device being used to set information related to a first relationship between a first N_Port_Name and a first LUN, the first N_Port_Name being related to a first host device of said plurality of host devices, the first LUN being related to a first storage region of said plurality of storage regions;
• wherein said storage control device sends information, indicating that said first host device is permitted to access said first storage region, to said first host device based on said first relationship.

A storage system adapted to be coupled to a plurality of host devices via a fibre channel, the storage system comprising:

• a plurality of storage devices corresponding to a first logical unit of a plurality of logical units;
• a storage control device controlling to store data, addressed to the first logical unit, into the plurality of storage devices;
• and
• an input device;
• wherein the storage control device receives a first frame sent from a first host device of the plurality of host devices to the first logical unit, and sends a second frame to the first host device in response to receiving the first frame,
• wherein an information, included in the second frame, indicates that the first logical unit is acceptable for inputting/outputting data from/to the first host device, if a first relationship between the first host device and the first logical unit is set by the input device, and
• wherein the information, included in the second frame, indicates that the first logical unit is not acceptable for inputting/outputting data from/to the first host device, if a second relationship between a second host device of the plurality of host devices and the first logical unit is set by the input device, instead of the first relationship.

A storage system adapted to be coupled to a plurality of host devices via a fibre channel, the storage system comprising:

• a plurality of storage devices corresponding to a first logical unit of a plurality of logical units;
• a storage control device controlling to store data, addressed to the first logical unit, into the plurality of storage devices;
• and
• an input device being adapted to be used to set whether or not a port of a first host device of the plurality of host devices is permitted to access the first logical unit for inputting/outputting data;
• wherein the storage control device receives a first frame sent from the port of the first host device to the first logical unit, and sends a second frame to the port of the first host device in response to receiving the first frame,
• wherein an information, included in the second frame, indicates that the first logical unit is acceptable for inputting/outputting data from/to the first host device, if the port of the first host device is permitted to access the first logical unit for inputting/outputting data, and
• wherein the information, included in the second frame, indicates that first logical unit is not acceptable for inputting/outputting data from/to the first host device, if the port of the first host device is not permitted to access the first logical unit for inputting/outputting data.

A storage system adapted to be coupled to a plurality of external devices via a fibre channel, the storage system comprising:

• a plurality of storage devices corresponding to a first logical unit of a plurality of logical units;
• a storage control device controlling to store data, addressed to the first logical unit, into the plurality of storage devices;
• and
• an input device being adapted to be used to set whether or not a port of a first external device of the plurality of external devices is permitted to access the first logical unit;
• wherein the storage control device receives a first frame sent from the port of the first external device to the first logical unit, and sends a second frame to the port of the first external device in response to receiving the first frame,
• wherein an information, included in the second frame, is changed by the storage control device based on whether or not the port of the first external device is permitted to access the first logical unit.

A storage system adapted to be coupled to a plurality of host devices via a fibre channel, the storage system comprising:

• a plurality of storage devices corresponding to a first logical unit of a plurality of logical units, the first logical unit having a first logical unit number (LUN);
• a storage control device controlling to store data, addressed to the first LUN, into the plurality of storage devices;
• and
• an input device being used to set information, which is used to provide LUN security to prevent unauthorized access to a LUN and which corresponds to a relationship between a first host device of the plurality of host devices and the first logical unit.

A storage system adapted to be coupled to a host device via a fibre channel, the storage system comprising:

• a storage control device that provides a plurality of logical units to the host device;
• and
• an input device being used to set information related to a first relationship between a first N_Port_Name and a first LUN, the first N_Port_Name being related to the host device, the first LUN being related to a first logical unit of said plurality of logical units;
• wherein said storage control device sends information, indicating that said first host device is permitted to access said first logical unit, to said first host device based on said first relationship.

A storage system adapted to be coupled to a plurality of host devices via a fibre channel, the storage system comprising:

• a storage control device that provides a plurality of logical units to at least one host device of the plurality of host devices, each of the plurality of logical units being specified from a fibre channel command frame sent from said at least one host device;
• and
• an input device being used to set information to a first relationship between a first N_Port_Name and first LUN, the first N_Port_Name being related to the at least one host device, the first LUN being related to a first logical unit of said plurality of logical units;
• wherein said storage control device sends information, indicating that said first host device is permitted to access said first logical unit, to said first host device based on said first relationship.
