Checking and Repairing Internal IP Address Continuity of OceanStor 18500&18800F&18800&HVS85T&HVS88T

Procedure

1. Log in to the CLI as an administrator, and run show upgrade package to view the current product version.

   

2. Based on the specific product version, perform the corresponding procedure to check and repair internal IP address continuity.
   • If the product version is V100R001C20, perform the following procedure:
     1. Run change user_mode current_mode user_mode=developer to enter the developer mode.
        NOTE:

        If an early storage system version (such as OceanStor 18000 V100R001SPC200) asks you to enter the password, enter debug@storage.
        NOTICE:

        Complete the following steps under the guidance of R&D engineers.
     2. Run minisystem to enter the minisystem mode.
        
        
     3. In the minisystem mode of each controller, run ifconfig to check whether internal IP addresses (the corresponding ports are eth2 and eth3) are consecutive.
        • If yes, no further action is required.
        • If no, go to step d.

        Check method:

        Internal IP addresses involve two network segments. The standard of IP address continuity is that internal IP addresses in the same network segment are consecutively in ascending order starting from the IP address of controller No.0. The following are examples where four controllers are involved:

        • If the IP addresses of eth2 on controller 0A, eth3 on controller 0B, eth2 on controller 1A, and eth3 on controller 1B are 126.126.126.100, 126.126.126.101, 126.126.126.102, and 126.126.126.103 respectively, internal IP addresses in this network segment are consecutive.
        • If the IP addresses of eth3 on controller 0A, eth2 on controller 0B, eth3 on controller 1A, and eth2 on controller 1B are 126.126.127.100, 126.126.127.101, 126.126.127.102, and 126.126.127.103 respectively, internal IP addresses in this network segment are consecutive.
        NOTE:

        If internal IP addresses in each network segment are consecutive, internal IP addresses of the system are consecutive.

     4. In the minisystem mode, run os_write_bay_cfg.sh -d to delete user-defined internal IP addresses, thereby making internal IP addresses consecutive. (After the system is restarted, the following internal IP addresses are automatically assigned: 126.126.126.100 to 126.126.126.103 and 126.126.127.100 to 126.126.127.103.)
        NOTICE:

        The change of internal IP addresses requires restarting the system, which leads to service interruption. It is recommended that you contact technical engineers to assess risks before performing the following repair operations.
        
        
        NOTE:

        The -d field of the os_write_bay_cfg.sh -d command indicates deleting user-defined internal IP addresses.
     5. Check whether internal IP addresses are consecutive.
        • If yes, go to step f.
        • If no, go to step h.
     6. After internal IP addresses are changed on all controllers, run reboot system in the developer mode of any controller to restart the system.
        
        
     7. After the system is powered on again, perform step b again to check whether internal IP addresses are consecutive.
        • If yes, no further action is required.
        • If no, go to step h.
     8. Collect related events and logs and contact Huawei technical support.
   • If the product version is V100R001C20SPC100 or V100R001C20SPC200, perform the following procedure:
     1. Run change user_mode current_mode user_mode=developer to enter the developer mode.
        NOTE:

        If an early storage system version (such as OceanStor 18000 V100R001SPC200) asks you to enter the password, enter debug@storage.
        NOTICE:

        Complete the following steps under the guidance of R&D engineers.

     4. In the developer mode, run change system inter_ip to change the internal IP address. Then, check whether the command is successfully executed.
        
        
        • If yes, go to step e.
        • If no, go to step g.
     5. In the developer mode, run reboot system to restart the system for the new internal IP address to take effect.
        
        
     6. After the system is powered on again, perform step b again to check whether internal IP addresses are consecutive.
        • If yes, no further action is required.
        • If no, go to step g.
