Caution

  • The ETERNUS DX8100 S6 does not support the [Add Memory] function.

  • Perform the start maintenance operation by using the [Start/End Maintenance] function before adding memory. If the operation has not been performed, addition cannot be started.

  • Be sure to use authorized additional parts. If parts other than the additional parts are used, operation is not guaranteed.

  • Registration of the memory license is required to use the added memory if the "GS License" has been registered in the ETERNUS DX8900 S6.

  • If the CM to which memory is to be added is a Main CM, the Main CM is switched.

  • The memory is added to all the enabled CMs installed in the storage system.

  • Refer to Memory Specifications of Each Model (per CM) to make sure to observe the memory expansion unit when adding memory. If the number of installed memory modules is less than the number of installed memory expansion units, the installed memory modules cannot be used.

  • Do not add memory when Storage Migration paths are set.

  • This function cannot be used under the following conditions:

    • The general status of the storage system is not normal

    • The Drive Enclosure (DE) may be blocked

    • Maintenance for the CM cannot be performed

    • A recovery operation for the CM is being performed

    • The Main CM cannot be switched

    • An error exists in another part

Note

  • If an activation fails midway through the memory adding process for the ETERNUS DX600 S6, the [Add Memory] function must be executed again.

    Perform the following procedure.

    1. Perform a maintenance for the target component that failed to be added.

    2. Restore the memory that failed to be added back to the initial state (by performing a preventive maintenance for the target CM to remove the memory).

      Refer to Hot Preventive Maintenance for details.

    3. Execute this function again.

  • Even if an activation fails midway through the memory adding process for the ETERNUS DX900 S6 or the ETERNUS DX8900 S6, the process can be resumed from where it was interrupted by executing this function again after a maintenance for the target component that failed to be added is complete.

  • For the ETERNUS DX900 S6 or the ETERNUS DX8900 S6, memory is added in descending order from the CM (CE#n CM#n) that is installed in the CE with the largest number. Add the memory in the Main CM last.

  • The physical capacity of the installed memory in the CM is displayed in the "Memory Size" field on the [Controller Module Detail] screen. Refer to the [Controller Module] function for details.
