Configuration information of a disk drive includes information such as, but not limited to, drive capacity, drive RPM, group RAID type, and drive firmware. Metadata associated with configuration information of the disk drive in a pool of disk drives is generally stored as Disk Drive Module (DDM) metadata in the disk drive. The configuration information is displayed to a user using a Graphical User Interface (GUI) or a Command Line Interface (CLI). When a disk drive fails, only the failed status of the disk drive is displayed to the user. Since the configuration information of the disk drive is stored in the disk drive, it is a challenge for the user to obtain configuration information for a disk drive that has failed.

Disclosed is a method and system for maintaining and displaying configuration information of a disk drive even in case of failure of the disk drive. The configuration formation for a disk drive in a pool of disk drives is maintained in each of the other drives in the pool of disk drives. In an embodiment, the configuration information may be stored outside the pool of disk drives. For example, the configuration information may be stored in a flash file system. Accordingly, when a user wishes to view configuration information for a disk drive that has failed, the configuration information for the failed disk drive is retrieved from other disk drives in the pool...
