  • Page 41

    3. Specify the size of the logical drive and the disk drives to be used. On the Logical Drive Size, specify the capacity of the logical drive. To use the maximum capacity of the disk, put a checkmark on the Use Maximum Capacity checkbox (a checkmark is put by default).

  • Page 42

    3.9 Deleting Logical Drive IMPORTANT: Never delete the logical drive in which the Windows file system is installed. Before deleting a logical drive, make sure that the Windows file system is not installed in the logical drive. 1. Click [Logical Drive View] in the Tree View. 2.

  • Page 45: Synchronizing Logical Drive

    3.10 Synchronizing Logical Drive Routine synchronization allows inconsistencies to be detected and repaired to prevent rebuilding from failing at a HDD fault. This is available for logical drives of RAID 1, 5, or 10. In order to keep the stable operation of the RAID system, it is strongly recommended to provide the routine synchronization by using the scheduling feature.

  • Page 46

    4. Click [Start Now]. The synchronization is started. The progress of synchronization appears in the Synchronization tab of each logical drive. Animation showing the synchronization is advanced appears in the Tree View. NOTE: Note that the processing rate decreases due to much load during synchronization.

  • Page 47: Scheduling Synchronization

    NOTES: The following message is registered when you first perform synchronization to the logical drive that has been created without initialization. Synchronization is requested to perform on the logical drive "LD-name” that has never been initialized. This does not have any influences on synchronization processing.

  • Page 48

    3. Select [Fix] or [Redundancy Check] from the [Policy] pull-down menu. Fix: If an inconsistency error is detected, data is repaired from the other mating disk configuring the RAID. Redundancy Check: If an inconsistency error is detected, the process is continued without repair of the error.

  • Page 49: Media Patrol

    3.11 Media Patrol The media patrol reads data in the following HDDs entirely. As HDDs can be deteriorated with age, faults in the HDDs may be detected only when they are accessed. By reading data in HDDs routinely, the media patrol enables such faults to be detected as early as possible. This enables the early appropriate action.

  • Page 50

    The progress of media patrol appears in the Media Patrol tab of each physical drive. Animation showing that media patrol is now advanced appears in the Tree View. NOTES: At the end of media patrol, always check the event log to see if any error occurs during media patrol.

  • Page 51: Scheduling Media Patrol

    3.11.1 Scheduling Media Patrol NOTE: A media patrol task has been scheduled to be done on AM0:00 every Wednesday as a default. To schedule routine media patrol, follow the procedure below: 1. Click the Physical Drive View icon in the Tree View. 2.

  • Page 52: Rebuilding Logical Drive

    3.12 Rebuilding Logical Drive The rebuild can recover redundancy when a single HDD is defected in the RAID level of 1, 10, or 5. During rebuild, data read and write operations are enabled. However, the redundancy is lost until the rebuild is completed. If a HDD is defected, the logical drive including the HDD is entered into the critical state, which is notified.

  • Page 53

    During rebuild, the progress appears in the Information and Rebuild tabs of the Management Window. Animation showing that the rebuild is advanced appears in the Tree View. Rebuild fails if more than 20 errors are found in read source disks. As proper rebuild has been impossible at that time, build the system again by using new disks.

  • Page 54

    At the completion of the rebuild, the logical drive returns to the normal state. NOTES: At the end of rebuild, always check the event log to see if any error occurs during rebuild. When a media error occurs, a message indicating the occurrence of the error appears before the message indicating that the rebuild has terminated normally.

  • Page 55

    IMPORTANT: Please make sure that Auto Rebuild Status is set to “Disable” in Controller- Settings tab to enable automatic start of rebuild. For details, see the description of the Settings tab in “3.6.1 Controller.” 1. Click the Logical Drive icon in the critical state in the Tree View. The status of the logical drive will be displayed in the Management Window.

    3.14 Expanding Logical Drive IMPORTANT: This feature is supported only with N8103-89. Before expanding a logical drive, always back up the data in the disks. If an unexpected error occurs during expansion, some data may be broken in the disks. Expansions in RAID5 and RAID0 are enabled.

  • Page 60

    4. Select the physical drive to be used for expansion. The available physical drives are enclosed with black frames. The selected physical drive is enclosed with a red frame. 5. Click the [Start Now] button. The expansion is started. The progress of expansion appears in the Expansion tab of the logical drive. Animation showing the expansion is advanced appears in the Tree View.
