1. A method, comprising:
- generating signature data indicating a plurality of metadata copy locations, each location identifying one of a plurality of storage devices and a copy location within the storage device, wherein each location contains one copy of the metadata, wherein the metadata includes system configuration information;
storing a copy of the signature data with each copy of the metadata in the storage devices; and
reading one copy of the metadata from one of the storage devices to obtain system configuration information to use to operate.

Abstract
Provided are a method, system, and program for storing and using metadata in multiple storage location. Signature data is stored in a system storage indicating a plurality of metadata copy locations, each locating identifying a storage device and a copy location within the storage device. Each location contains one copy of the metadata, wherein the metadata includes system configuration information. A copy of the signature data is stored with each copy of the metadata.
