Parameters

Meaning

Node_IP

Brick_path

Storage unit path.

Impact on the System

The backup proxy will not run any task that needs to connect to the storage unit until the connection is restored.

Possible Causes

  • The network connection between the backup proxy and storage device is interrupted.
  • The network performance is poor.
  • If the storage unit type is S3, check whether the AK and SK of S3 are correct.

Procedure

  1. Possible cause 1: The network connection between the backup proxy and storage device is interrupted.

    1. Use PuTTY to log in to the backup proxy where the alarm is reported.

      Default account: hcp. Default password: PXU9@ctuNov17!.

    2. Run the su root command and enter the password of user root to switch to user root.

      The default password of user root is Cloud12#$.

    3. If the IP address is an IPv4 address, run the ping IP address of storage unit command. If the IP address is an IPv6 address, run the ping6 IP address of storage unit command. Check whether the IP addresses can be pinged.
      • If yes, 2.
      • If no, contact the equipment room administrator to recover the network connectivity and ensure that the network connection is normal.

  2. Possible cause 2: The network performance is poor.

    1. Check whether packet loss occurs based on the command output in 1.
      • If yes, contact the administrator to improve the network performance and ensure that the communication between the backup proxy and the storage unit is stable. No further action is required.
      • If no, 3.

  3. Possible cause 3: If the storage unit type is S3, check whether the AK and SK of S3 are correct.

    1. Use PuTTY to log in to the backup proxy where the alarm is reported.

      Default account: hcp. Default password: PXU9@ctuNov17!.

    2. Run the su root command and enter the password of user root to switch to user root.

      The default password of user root is Cloud12#$.

    3. Run the cd /opt/huawei-data-protection/ebackup/sbin command to go to the sbin directory.
    4. Run the export LD_LIBRARY_PATH=/opt/huawei-data-protection/ebackup/libs command to import the LD_LIBRARY_PATH environmental variable.
    5. Run the ./uds_plug-in TestBucket S3_IP bucketName AK SK command to check whether the AK, SK, and bucket name are correct.
      • If yes, contact technical support engineers.
      • If no, contact the administrator to obtain the correct AK, SK, and bucket name, and reconfigure the storage unit.
