An AC Fails to Be Upgraded

Symptom

An AC fails to be upgraded or downgraded.

Possible Causes

• There is insufficient available storage space on the AC.
• The AC upgrade file does not match the AC model.
• The AC software version is incompatible.
• The network between the file server and the client is disconnected.
• The user name or password of the file server is incorrect.
• The AC upgrade file is changed.

Troubleshooting Procedure

1. Check whether a PC can successfully ping the AC.
   1. Access the Windows command line interface (CLI) on your PC, and run the ping command to check whether the PC can successfully ping the AC.

      C:\Users\xxxx> ping 192.168.0.1
      Pinging 192.168.0.1, with 32 bytes of data:
      Reply from 192.168.0.1: bytes=32 time<1ms TTL=128
      Reply from 192.168.0.1: bytes=32 time<1ms TTL=128
      Reply from 192.168.0.1: bytes=32 time<1ms TTL=128
      Reply from 192.168.0.1: bytes=32 time<1ms TTL=128
      Ping statistics for 192.168.0.1:
      Packets: Sent = 4, Received = 4, Lost = 0 (0% lost)
      Estimated RTT (ms):
      Minimum = 0ms, Maximum = 0ms, Average = 0ms

      If the message "Request time out" is displayed, the target device is unreachable.

   2. If the PC fails to ping the AC, change the IP address of the AC or PC.

      To change the IP address of the AC, perform the following steps:

      1. Run the display ip interface brief command in any view on the AC to check whether the IP address of the AC is correctly configured.
      2. If the IP address is incorrect, run the ip address ip-address { mask | mask-length } command in the interface view to reconfigure the IP address of the AC.
   3. After the IP address is modified, run the ping command on the PC again to check whether the PC can successfully ping the AC.

2. Check whether the user name and password of the file server are correct.

   When you load the system software through a file server, ensure that the FTP, SFTP, or TFTP service is enabled on the file server and the user name and password are correctly configured.

   1. Perform the following operations to check whether the AC can access the file server.

      Assume that the IP address of the file server is 192.168.0.2, and the user name and password are huawei and huawei123, respectively.

      • For the FTP server:

        <AC6605> ftp 192.168.0.2
        Trying 192.168.0.2 ...
        Press CTRL+K to abort
        Connected to 192.168.0.2.
        220 FTP service ready.
        User(192.168.0.2:(none)):huawei
        331 Password required for huawei.
        Enter password:
        230 User logged in. 

        If the system prompts you to enter the user name and password, the FTP service is enabled on the file server. You need to enter the user name and password to access the file server.

      • For the SFTP server:

        <AC6605> system-view
        [AC6605] ssh client first-time enable
        [AC6605] sftp 192.168.0.2
        Please input the username: huawei
        Trying 192.168.0.2 ...
        Press CTRL+K to abort
        Enter password:
        sftp-client>

        If the system prompts you to enter the password after you entered the user name, the SFTP service is enabled on the file server. You need to enter the password to access the file server.

      • For the TFTP server:

        No user name or password is required for the TFTP server. You can upload a local file on the AP to the file server to check whether the TFTP service is enabled on the file server. If the file is successfully uploaded, the TFTP service is enabled on the file server.

        The following uses the local file test.txt as an example.

        <AC6605> tftp 192.168.0.2 put test.txt

   2. If the FTP, SFTP, or TFTP service is disabled, enable the service on the file server.

      For details, see the help information of the corresponding server.

   3. When a PC functions as the FTP, SFTP, or TFTP server, you are advised to temporarily disable the firewall and check whether the AC can access the file server.
   4. If the user name and password are incorrect, reconfigure the user name and password.

      You are advised to configure a password that consists of letters and digits but no special characters.

3. Check whether the AC has sufficient available storage space.
   1. Log in to the AC, and run the dir command in the user view to check whether the remaining space on the flash memory or SD card is sufficient for storing the system software package to be upgraded.

      <AC6605> dir
      Directory of flash:/
      
        Idx  Attr     Size(Byte)  Date        Time(LMT)  FileName

      1,927,220 KB total (1,130,464 KB free)

      The command output shows that there is 1,130,464 KB available flash space. Compare the remaining flash space with the space required for upgrading the system software package. If the remaining flash space is insufficient for the upgrade, delete useless files from the flash memory.

   2. Run the delete command to delete unnecessary files from the flash memory. Ensure that there is sufficient space to store upgrade files. Before deleting the files, ensure that the files to be deleted are backed up or no longer needed. The following shows an example of deleting the earlier version AC6605V200R003C00.cc from the flash:/ directory.

      <AC6605> delete /unreserved flash:/AC6605V200R003C00.cc
      Warning: The contents of file flash:/AC6605V200R003C00.cc cannot be recycled 
      . Continue? (y/n)[n]:y
      Info: Deleting file flash:/AC6605V200R003C00.cc...succeed.

4. Check whether the AC upgrade file is correct.
   1. Run the display version command to check whether the AC software version matches the AC device model.

      <HUAWEI> display version
      Huawei Versatile Routing Platform Software
      VRP (R) software, Version 5.160 (AC6605 V200R006C10SPC100)
      Copyright (C) 2011-2015 HUAWEI TECH CO., LTD
      ......

      The AC software version must match its device model, that is, the software version for an AC model cannot be loaded to a different AC model.

   2. Check whether the size of the AC upgrade file is consistent with that of the source file.

      <HUAWEI> dir
      Directory of flash:/
      
        Idx  Attr     Size(Byte)  Date        Time(LMT)  FileName
          0  -rw-     47,214,212  Jul 16 2015 19:09:33   AC6605V200R005C10SPC300.cc
          1  -rw-     53,195,539  Feb 02 2016 10:31:56   AC6605V200R006C10SPC100.cc
      
      206,324 KB total (93,496 KB free)

      Compare the size of the AC upgrade file with the value shown in the Size attribute of the upgrade file in Windows. If the values are different, the AC upgrade file has been modified.

   3. If the AC upgrade file does not match the AC device model, or if the upgrade file has been modified, log in to the Huawei enterprise technical support website (http://support.huawei.com/enterprise) to obtain an upgrade file of the corresponding AC device model.

5. Check whether the AC software version is compatible.

   If an AC is running V200R001 or V200R002, upgrade it to V200R003 before upgrading it to a later version.

   The configuration models for V200R005 and V200R006 are different. Before upgrading V200R005 to V200R006, convert the configuration file. For details, see the Upgrade Guide of the corresponding version.

   1. Run the display version command to check the version information.

      <AC6605> display version
      Huawei Versatile Routing Platform Software
      VRP (R) software, Version 5.160 (AC6605 V200R002C00)
      ......

      The command output shows that the current version is V200R002C00, so it must be upgraded to V200R003 first.

   2. Enable the upgrade function.

      You must enable the upgrade function before upgrading V200R001 or V200R002 to V200R003. This operation is not required for upgrading a V200R003 version to another V200R003 version.

      <AC6605> system-view
      [AC6605] upgrade enable
      Info:Current upgrading version is on.

   3. Upgrade the AC from V200R001 or V200R002 to V200R003 before upgrading it to a later version. For details, see the Upgrade Guide at http://support.huawei.com/enterprise.

6. Collect the fault information.
