How to Add A Heterogeneous Device to the Whitelist?

How to Add A Heterogeneous Device to the Whitelist?

Question

How to add the array to the whitelist when alarm "Incompatible Heterogeneous Array Connected to the System" is reported on the local storage system?

Answer

Contact Huawei technical support engineers to decide whether to add the array to the whitelist. If yes, the engineers will perform operations. Do not perform the operations by yourself; otherwise, services may be affected.

The following takes HP P2000 G3 as an example. In practice, the array model and vendor may be different.

  1. Log in to the interface for managing heterogeneous storage devices that have been taken over, and record the vendor, model (VID and PID), and running status of the array.



  2. Check the heterogeneous storage arrays that are compatible with the local storage system.
    1. On the CLI, log in to the storage system and enter the engineer mode.

      admin:/>change user_mode current_mode user_mode=engineer
      engineer:/>

    2. Run show remote_device support_array_list to check the compatible heterogeneous storage arrays.

      engineer:/>show remote_device support_array_list
      Manufacturer  Model             Path Selector  Fail Over  Fail Back       ASL ID  
        ------------  ----------------  -------------  ---------  --------------  ------  
        HUASY         V1500             ROUND_ROBIN    ENABLE     DELAY_FAILBACK  1       
        HUASY         V1800             ROUND_ROBIN    ENABLE     DELAY_FAILBACK  1 
        EMC           VPLEX             LEAST_QUEUE    ENABLE     NOT_FAILBACK    22      
        HP            MSA2212fc         ROUND_ROBIN    ENABLE     NOT_FAILBACK    10      
        HP            P2000 G3          ROUND_ROBIN    ENABLE     NOT_FAILBACK    10      
        HP            XP20000           ROUND_ROBIN    ENABLE     NOT_FAILBACK    12
      NOTE:
      You can find out the vendor of a heterogeneous storage array by running show remote_device support_array_list manufacturer=HP, and then check the array models of this vendor compatible with the local storage system.
      engineer:/>show remote_device support_array_list manufacturer=HP
      Manufacturer  Model       Path Selector  Fail Over  Fail Back     ASL ID  
        ------------  ----------  -------------  ---------  ------------  ------  
        HP            MSA2212fc   ROUND_ROBIN    ENABLE     NOT_FAILBACK  10      
        HP            P2000 G3    ROUND_ROBIN    ENABLE     NOT_FAILBACK  10      
        HP            XP20000     ROUND_ROBIN    ENABLE     NOT_FAILBACK  12

    3. Check whether the heterogeneous array whose information is queried in 1 is one of the compatible heterogeneous storage devices queried in 2.

      • If yes, go to 3.
      • If no, contact Huawei technical support engineers to confirm whether a corresponding heterogeneous support package needs to be developed.

  3. Add the array to the whitelist.
    1. Run show remote_device elink to obtain information about the link through which the array is connected.

      engineer:/>show remote_device elink 
      FC Link:
        ID         Health Status  Running Status  Local Controller  Remote Device Type           In Remote Device  Remote Device ID  Remote Device WWN    Remote Controller  
        ---------  -------------  --------------  ----------------  -------------------------    ----------------  ----------------  -----------------    -----------------  
        268435456  Normal         Link Up         0A                Other Manufacturer Device    Yes               512               --                   --                 
        268435457  Normal         Link Up         0A                Other Manufacturer Device    Yes               512               --                   --                 
        268435458  Normal         Link Up         0B                Other Manufacturer Device    Yes               512               --                   --                 
        268435459  Normal         Link Up         0B                Other Manufacturer Device    Yes               512               --                   --          
      • If Remote Device ID is 512, the array has not been added to the whitelist. Go to 3.b.
      • If Remote Device ID is not 512, the array has been added to the whitelist. No further action is required.

    2. Obtain the VID and PID of the array based on the link ID.

      engineer:/>show remote_device array_info link_id=268435456
      Link ID          : 268435456       
        Remote Device ID : 512             
        Vendor           : HP          
        Product ID       : P2000 G3 FC
      In this example, the VID and PID is HP and P2000 G3 FC respectively.

    3. Run show remote_device white_list to check the heterogeneous device whitelist of the local storage device, and compare whether the VID and PID queried in 3.b are on the whitelist.

      engineer:/>show remote_device white_list
      Record ID  Vendor    Product ID        Path Selector  Fail Back       Fail Over  ASL ID  Is User Added  
        ---------  --------  ----------------  -------------  --------------  ---------  ------  -------------  
        11         EMC       CX4-120           ROUND_ROBIN    DELAY_FAILBACK  ENABLE     3       No             
        12         EMC       CX4-240           ROUND_ROBIN    DELAY_FAILBACK  ENABLE     3       No
        46         HP        HSV360            ROUND_ROBIN    NOT_FAILBACK    ENABLE     5       No             
        47         HP        P2000G3 FC/iSCSI  ROUND_ROBIN    NOT_FAILBACK    ENABLE     10      No             
        48         HP        MSA2212fc         ROUND_ROBIN    NOT_FAILBACK    ENABLE     10      No  
        
      • If yes, no further action is required.
      • If no, add the array to the whitelist manually.

    4. Run add remote_device white_list to add the array to the whitelist.

      Note the following when running this command:
      • The spaces in vendor and product names can be replaced by asterisks (*).
      • Vendor and Product_id must be the same as the information queried in 3.b.
      • Path Selector, Fail Back, Fail Over, and ASL ID must be the same as the policies of the compatibility list queried in 2.
      engineer:/>add remote_device white_list vendor=HP product_id=P2000*G3*FC path_selector=ROUND_ROBIN fail_back=NOT_FAILBACK fail_over=ENABLE asl_id=10
      Command executed successfully.

    5. Run show remote_device whitelist to check the whitelist and confirm that the array has been added to the whitelist.

      engineer:/>show remote_device white_list
      Record ID  Vendor    Product ID        Path Selector  Fail Back       Fail Over  ASL ID  Is User Added

        11         EMC       CX4-120           ROUND_ROBIN    DELAY_FAILBACK  ENABLE     3       No             
        12         EMC       CX4-240           ROUND_ROBIN    DELAY_FAILBACK  ENABLE     3       No 
        46         HP        HSV360            ROUND_ROBIN    NOT_FAILBACK    ENABLE     5       No             
        47         HP        P2000G3 FC/iSCSI  ROUND_ROBIN    NOT_FAILBACK    ENABLE     10      No             
        48         HP        MSA2212fc         ROUND_ROBIN    NOT_FAILBACK    ENABLE     10      No             
        49         HP        MSA2012fc         ROUND_ROBIN    NOT_FAILBACK    ENABLE     10      No             
        154        HP        HSV100            ROUND_ROBIN    NOT_FAILBACK    ENABLE     18      No             
        159        HP        P2000 G3 FC       ROUND_ROBIN    NOT_FAILBACK    ENABLE     10      Yes            
        50         HUASY     V1500             ROUND_ROBIN    DELAY_FAILBACK  ENABLE     1       No
      If a wrong array has been added, run remove remote_device white list to delete the record. For example, to delete a record whose Record ID is 159, run the following command.
      engineer:/>remove remote_device white_list record_id=159
      WARNING: You are going to remove remote device white list. This operation deletes the information about the remote device white list from the system.
      Suggestion: Before you perform this operation, ensure that you have selected the correct remote device white list and confirm that the remote device white list can be deleted.
      Have you read warning message carefully?(y/n)y
      Are you sure you really want to perform the operation?(y/n)y
      Command executed successfully.
