Expanding SPU Capacity for the Active and Standby NIPs in Hot Standby Scenarios (V500R001C50 and Later Versions)

Expanding SPU Capacity for the Active and Standby NIPs in Hot Standby Scenarios (V500R001C50 and Later Versions)

This section describes how to expand SPU capacity for the active and standby NIPs in hot standby scenarios.

Precautions

Expand SPU capacity as follows only when V500R001C50 or a later version is being used on the NIP.

Before expanding SPU capacity, prepare new SPUs. The SPUs to be installed on the active and standby NIPs for capacity expansion must be of the same model. In addition, they must be installed in the same slot on the active and standby NIPs.

If two NIPs work in active/standby mode, you must first expand the SPU capacity for the standby NIP and then for the active NIP. If two NIPs work in load balancing mode, run the hrp switch active command on one NIP to switch the operating mode to the active/standby mode and then expand SPU capacities.

The following table lists which services are affected when an SPU is hot-swapped.

Preparations

Tools:

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

  • ESD bag

Record card tables for the two NIPs. This will allow you to compare the card tables with those after capacity expansion to check whether the capacity expansion succeeds.

Procedure

  1. Confirm where the SPUs are to be installed.

    Before expanding SPU capacity, first confirm where the SPUs are to be installed, including the cabinets, chassis, and slots. Ensure that the SPUs are installed in the same slot on the active and standby NIPs.

  2. Check whether the connectors of the SPUs to be installed are damaged.
  3. Optional: If two NIPs work in load balancing mode, switch the operating mode to the active/standby mode. To switch the operating mode, run the hrp switch active command on either NIP.

    NOTE:
    If the two NIPs work in active/standby mode, skip this step.
    HRP_M<sysname> system-view
    HRP_M[sysname] hrp switch active

    The NIP on which the hrp switch active command is executed has its VGMP group priority increased by 1 to be higher than that of the other NIP and therefore becomes the active NIP. The other NIP becomes the standby NIP. Services on the standby NIP are switched to the active NIP. Service switchover takes a few moments. To ensure service continuity, run the hrp switch active command and wait one minute before performing subsequent operations.

  4. Run the undo hrp track spu enable command on the standby NIP to disable the VGMP group from monitoring the SPU.

    HRP_S<sysname> system-view
    HRP_S[sysname] undo hrp track spu enable

    After the SPU is inserted into the standby NIP, its VGMP group priority increases and becomes higher than that of the active NIP, triggering active/standby switchover. In addition, after the SPU is inserted, session tables on the standby NIP are deleted. If active/standby switchover occurs at this time, service traffic is discarded by the standby NIP due to failure to match session tables after being diverted to the standby NIP. Therefore, before the SPU is inserted into the standby NIP, run the undo hrp track spu enable command on the standby NIP to disable the VGMP group from monitoring the SPU. In this way, after the SPU is inserted into the standby NIP, its VGMP group priority does not increase, active/standby switchover is not triggered, and service traffic is still forwarded by the active NIP.

  5. Insert the SPU into the slot of the standby NIP.
    1. Take out the new SPU from the ESD bag.

      • Pull out the SPU slowly and smoothly so that it does not bump into neighboring boards and cause a malfunction.
      • When inserting an SPU, do not touch the parts on it to avoid damaging the SPU.

    2. Holding the captive screws, insert the SPU smoothly along the guide rails of the slot until the SPU is inserted fully into the slot, as shown in Figure 3-15 (1).
    3. Turn the ejector levers on the SPU outward and upward to form a 45-degree angle, and at the same time push the SPU into the slot. Then, turn the ejector levers inward and downward until the panel of the SPU touches the slot, as shown in Figure 3-15 (2).
    4. Using the Phillips screwdriver, turn the two captive screws clockwise to tighten them, as shown in Figure 3-15 (3).

      Figure 3-15  Inserting an SPU

  6. Check the running status of the inserted SPU.
    1. Run the display device command on the standby NIP to query the running status of the SPU motherboard. The SPU motherboard is running properly if all items on the SPU motherboard in the corresponding slot are displayed as follows:

      HRP_S<sysname> display device
      NIP6830's Device status:
      Slot #    Type       Online    Register      Status      Primary    
      - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
      1         SPU        Present   Registered    Normal      NA         
      2         SPU        Present   Registered    Normal      NA         
      3         LPU        Present   Registered    Normal      NA         
      4         MPU        Present   NA            Normal      Master     
      6         CLK        Present   Registered    Normal      Master     
      8         PWR        Present   Registered    Normal      NA         
      9         PWR        Present   Registered    Abnormal    NA         
      10        FAN        Present   Registered    Normal      NA         

    2. Run the display device pic-status command on the standby NIP to query the running status of the subcard. The subcard is running properly if all items on the corresponding subcard are displayed as follows:

      HRP_S<sysname> display device pic-status
      Pic-status information in Chassis 1:                                            
      - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
      SLOT PIC Status     Type                   Port_count Init_result   Logic down  Registered Cpu

      1    1   Registered SPU_CARD_TYPE_SPCC     0          SUCCESS       SUCCESS     CPU3          
      2    1   Registered SPU_CARD_TYPE_SPCH     0          SUCCESS       SUCCESS     CPU2,CPU3     
      3    0   Registered LAN_WAN_5x10GF_B_CARD  5          SUCCESS       SUCCESS     
      3    2   Registered ETH_24xGF_B_CARD       24         SUCCESS       SUCCESS     

    3. Run the display firewall cpu-table command on the standby NIP to view the card table. Compare the card table after expansion with that before capacity expansion to confirm whether the card table is updated. If the card tables before and after capacity expansion are different, the card table has been updated successfully.

      HRP_S<sysname> system-view
      HRP_S[sysname] diagnose
      HRP_S[sysname-diagnose] display firewall cpu-table

      The NIP allocates sessions to various CPUs for processing based on the card table. After the card table of the standby NIP is updated, the standby NIP sends the updated card table to the active NIP. After receiving the new card table from the standby NIP, the active NIP synchronizes session tables to the standby NIP. During session backup, the active NIP allocates sessions to CPUs for processing based on the card table of the standby NIP. In this way, the standby NIP can properly identify and process sessions after they are backed up to the standby NIP.

      Registering the SPU and updating the card table on the standby NIP FW takes around 20 minutes.

      Session backup between the active and standby NIPs takes around 2 minutes. Therefore, after confirming that the card table is updated, wait 2 minutes before performing subsequent operations.

  7. Run the hrp track spu enable command on the standby NIP to enable the VGMP group to monitor the SPU.

    HRP_S<sysname> system-view
    HRP_S[sysname] hrp track spu enable

    After the VGMP group is enabled to monitor the SPU, the VGMP group priority of the standby NIP becomes higher than that of the active NIP, triggering active/standby switchover. The standby NIP assumes the active role and processes service traffic, and the active NIP enters the standby mode.

    Service switchover takes a moment. To ensure service continuity, run the hrp track spu enable command and wait one minute before performing subsequent operations.

  8. Optional: If two NIPs work in load balancing mode, perform 3 to switch the operating mode to the active/standby mode. After 7 is complete, run the undo hrp switch active command on the NIP on which the hrp switch active command is executed (namely, the NIP in standby status) to cancel the operations from 3.

    If two NIPs work in active/standby mode, and operations in 3 are not performed, skip this step.

    HRP_S<sysname> system-view
    HRP_S[sysname] undo hrp switch active

  9. Repeat 4 to 7 on the original active (now standby) NIP to expand its SPU capacity.
  10. Check whether the service is working properly.
