Abstract

A method for monitoring according to a hint when allocating a storage volume. When a threshold value violation has occurred, judgement is performed from which use purpose the threshold value derives. The management computer for managing a computer system includes a unit for creating a storage volume according to a hint, a unit for deciding a threshold value for managing the storage volume according to the use purpose of the storage volume, a unit for acquiring a performance value from the storage apparatus, and a unit for comparing the acquired performance value to the threshold value and notifying a warning including a message based on the hint when a threshold value violation is detected.

Claims

1. A computer-readable storage medium containing a computer system management program for managing a computer system having a storage apparatus and for causing a computer to execute steps of:

creating a storage volume in the storage apparatus according to a parameter indicating a characteristic of the storage volume;

deciding a threshold value associated with performance information indicating performance of the storage volume;

acquiring the performance information indicating the performance of the storage volume of the storage apparatus; and

comparing the performance information to the threshold value and detecting a threshold value violation.
