ABSTRACT:
Methods and structure for storing volume and other configuration information on all disk drives of a volume group and for performing pre-merge operations to inform a user of the pending availability of the identified volumes. Configuration information has been historically stored in two distinct areas of configuration information on disk drives—a volume information area and an “other” information area. Aspects of the invention provide for storing all configuration information in the “other” information area. All disks of a system therefore include all configuration information relating both to volumes and to pseudo volume. A pre-merge operation is performed when each disk drive is inserted into a storage system to present new volume information to a user. When the last disk drive of a volume group is inserted, the user may select new volumes to be imported into the system.
