(Optional) Performing the Pre-expansion Evaluation

Procedure

1. Open SmartKit.
2. Add a storage device to SmartKit.
   1. In the SmartKit main window, click the Devices tab and select Add.
   2. In Basic Information, select Specify IP Address (add a device by the IP address) and enter the management IP address of the storage system. Then click Next.
   3. In the Login Information area, enter the user name and password of the storage system super administrator and click Finish.
   • When a device is added for the first time or a device certificate is not trusted, a message is displayed indicating that the connection is not trusted.
   • When an SSH server is added for the first time or the fingerprint of an SSH server changes, a message is displayed asking whether you want to continue to register the SSH server.

3. In the SmartKit main window, choose Home > Storage > Capacity Expansion > Expansion Evaluation.

   The Expansion Evaluation page is displayed.

4. Select devices.
   1. Click Device Selection. The Select Devices dialog box is displayed.
   2. Select the storage system to be expanded and the save path for task results. Click OK.

      After the expansion evaluation is complete, the storage system's configuration data is automatically backed up to the \data\config directory in the task result package. The backup can be used to restore the storage system in the event of an expansion failure.

5. Evaluate the capacity expansion solution.
   1. Click Expansion Evaluation.

      The Expansion Configuration page is displayed.

   2. (Optional) For devices that are configured with HyperMetro, select the device you want to perform capacity expansion evaluation from the device list and click Next.
   3. Select a capacity expansion scenario.

      Select Add disks, disk enclosures, and disk cabinets in Capacity expansion scenario.

   4. Click Add Hardware Information and Expansion Mode.

      You can add multiple configuration policies.

   5. Specify the configuration parameters according to the capacity expansion plan. Table 8-2 lists the parameters.
      Table 8-2 Capacity evaluation parameters

      Parameter	Description
      Storage Capacity Expansion Mode	Method to add storage space.
      BOM of Disk	BOM code of the new disk. NOTE: If the BOM code of the new disk is the same as an existing one in the storage system, select the BOM code from the drop-down list. If the BOM code of the new disk is not included in the drop-down list box, select Customize. To add multiple disk types, click Add Hardware Information and Expansion Mode to add new configuration policies.
      Disk Type	Type of the new disks. NOTE: When Customize is selected for BOM of Disk, you need to manually select a disk type. Self-encrypting drives (SEDs) are supported.
      Physical Capacity of a Single Disk	Capacity of the new disks. NOTE: When Customize is selected for BOM of Disk, you need to manually enter the disk capacity.
      Capacity Unit	Capacity unit of the new disks. NOTE: When Customize is selected for BOM of Disk, you need to manually select a capacity unit.
      Disk Quantity	Number of new disks.
      Operation	You can click Delete to delete the current configuration policy.

   6. Click Next.

      The Information page is displayed.

   7. Read and confirm the displayed message, and click OK.

      The Start Evaluation page is displayed and the system starts evaluating the capacity expansion solution.

      • After the evaluation is complete, click Open the report to go to the save path of the evaluation report. The report is a .zip file named by the evaluation time.
      • You can also click View the report to open the report directly.
   8. Click Finish.

   Rectify the failed items (if any) according to the suggestions and evaluate the solution again. If the items fail again, contact Huawei technical support engineers for assistance. Otherwise, risks may arise during capacity expansion.
