RoleName

Specifies the role for which the alarm is generated.

Impact on the System

The authentication services are unavailable and cannot provide security authentication functions for web upper-layer services. Users may be unable to log in to MRS Manager.

Possible Causes

The OLdap resource on which OKerberos depends is abnormal.

Procedure

  1. Check whether the OLdap resource on which OKerberos depends is abnormal in Manager.

    1. Log in to the active management node.
    2. Run the following command to check whether the OLdap resource managed by HA is normal:

      sh ${BIGDATA_HOME}/OMSV100R001C00x8664/workspace0/ha/module/hacom/script/status_ha.sh

      The OLdap resource is normal when the OLdap resource is in the Active_normal state on the active node and in the Standby_normal state on the standby node.

      • If yes, go to 3.
      • If no, go to 2.

  2. Resolve the problem by following the instructions in ALM-12004 OLdap Resource Abnormal (For MRS 2.x or Earlier). After the OLdap resource status recovers, check whether the OKerberos resource is normal.

    • If yes, no further action is required.
    • If no, go to 3.

  3. Collect fault information.

    1. On MRS Manager, choose System > Export Log.
    2. Contact the O&M engineers and send the collected logs.
