Abstract

A performance information display method using a computer, includes the steps, in the computer, of reading out information data of a storage device previously stored in a storage device and information data of a plurality of devices utilizing the storage device, displaying an identifier of the storage device and identifiers of a plurality of devices utilizing the storage device on a screen on the basis of the information data read out, accepting a command to select the displayed identifier of the storage device, and displaying performance information data of the devices utilizing the selected storage device in association on the basis of the accepted command and the information data read out.

Claims

1. A management computer comprising:

a communication device configured to couple with;

a storage system including a plurality of RAID groups and providing storage areas in the plurality of RAID groups; and

a plurality of computers configuring a plurality of computer volumes for accessing the storage areas;

a memory storing;

(a) computer performance information including first performance values of the plurality of computer volumes; and

(b) relation information including relationships between the plurality of computer volumes and the plurality of RAID groups; and

a processor configured to;

(A) acquire an ID of a certain RAID group;

(B) identify at least one of the plurality of computer volumes having relationship to the certain RAID group, based on the relation information; and

(C) display at least one of the first performance values corresponding to the at least one of the plurality of computer volumes.

2. A management computer according to claim 1,
