Storage system and a storage management system
First Claim
1. A storage system comprising:
- a plurality of physical ports connected with a name management device, a plurality of computers, and a packet transfer device through a network;
a control device;
a memory; and
a plurality of disk devices, and wherein said control device manages a plurality of logical volumes created on storage areas included in said plurality of disk devices;
wherein said memory stores information about connecting relation among said plurality of physical ports included in said storage system, a plurality of physical ports included in said plurality of computers, and a plurality of physical ports included in said packet transfer device; and
wherein said control device reads information of an identifier of a first computer of said plurality of computers and an identifier of a first logical volume of said plurality of logical volumes from a management terminal connected with said storage system, selects an unused first physical port of said plurality of physical ports included in said packet transfer device and a second physical port of said plurality of physical ports included in said packet transfer device connected with said storage system by referring to said information about connecting relation, transmits information of a group composed of said first computer and said first logical volume to said name management device, and instructs said packet transfer device to execute a configuration of allowing packets to be transferred between said first physical port and said second physical port.

Abstract
A storage device managing one or more logical volumes is connected with a name management device through an IP-SAN 6 composed of a switch. The storage device stores a topology table saving connecting relation among physical ports of host, physical ports of the storage device and physical ports of the switch, reads an identifier of the host and an identifier of the logical volume, selects a unused first physical port of the switch by referring to the topology table, selects a second physical port of the switch connected with the storage device, registers a group composed of the host and the logical volume with the name management device, and executes a configuration of allowing packets to be transferred between the first and the second physical ports with respect to the switch.

16. A storage management computer comprising:
-
a network interface being connected with a storage system having a plurality of physical ports and a plurality of logical volumes, a name management device, a plurality of computers and a packet transfer device through a network;
a control device; and
a memory, and wherein said memory stores information about connecting relation among said plurality of physical ports included in said storage system, a plurality of physical ports of said computers, and a plurality of physical ports included in said packet transfer device, and wherein said control device receives information about an identifier of a computer of said plurality of computers and an identifier of a logical volume of said plurality of logical volumes, selects an unused first physical port of said plurality of physical ports included in said packet transfer device and a second physical port of said plurality of physical ports included in said packet transfer device connected with said storage system by referring to said information about connecting relation, transmits a request for registering a group composed of said computer and said logical volume to said name management device through said network interface, and transmits a request for instruction a configuration of allowing packets to be transferred between said first physical port and said second physical port to said packet transfer device through said network interface. - View Dependent Claims (17)

19. A storage system comprising:
-
a plurality of physical ports connected with a name management device, a plurality of computers, and a switch device through a network;
a control device;
a memory; and
a plurality of disk devices, and wherein said control device manages a plurality of logical volumes created on storage areas included in said plurality of disk devices;
wherein said memory stores a topology table corresponding to information about connecting relation among said plurality of physical ports included in said storage system, a plurality of physical ports included in said plurality of computers, and a plurality of physical ports included in said switch device, wherein said control device reads information of an identifier of a first computer of said plurality of computers and an identifier of a first logical volume of said plurality of logical volumes from a management terminal connected with said storage system, selects a first physical port to be used for communication between said storage system and said first computer from said plurality of physical ports included in said switch device, selects a second physical port included in said switch device and connected with said storage system, transmits information about a group composed of said first computer and said first logical volume to said name management device, and instructs said switch device to execute a configuration of allowing packets to be transferred between said first physical port and said second physical port, wherein after executing said configuration of said switch device, said control device specifies a third physical port included in said storage system connected with said second physical port by referring to said information about connecting relation, assigns said third physical port to said first logical volume, allows said first computer to access said first logical volume through the use of said third physical port, and wherein said control device specifies a physical port with the smallest number of assigned logical volumes from said plurality of physical ports included in said storage system when selecting said second physical port and also selects a physical port included in said switch device connected with said specified physical port as said second physical port.
