RoleName

Specifies the role for which the alarm is generated.

Specifies the host for which the alarm is generated.

Impact on the System

No operation can be performed for the KrbServer and LdapServer users in the cluster. For example, users, user groups, or roles cannot be added, deleted, or modified, and user passwords cannot be changed on MRS Manager. Authentication for existing users in the cluster is not affected.

Possible Causes

  • The node where the LdapServer service resides is faulty.
  • The LdapServer process is abnormal.

Procedure

  1. Check whether the nodes where the two SlapdServer instances of the LdapServer service reside are faulty.

    1. On MRS Manager, choose Service > LdapServer > Instance to go to the LdapServer instance page. Obtain the host name of the node where the two SlapdServer instances reside.
    2. On the Alarm page of MRS Manager, check whether alarm ALM-12006 Node Fault is generated.
      • If yes, go to 1.c.
      • If no, go to 2.a.
    3. Check whether the host name in the alarm is consistent with the host name in 1.a.
      • If yes, go to 1.d.
      • If no, go to 2.a.
    4. Rectify the fault by following the steps provided in ALM-12006 Node Fault.
    5. In the alarm list, check whether alarm ALM-25000 LdapServer Service Unavailable is cleared.
      • If yes, no further action is required.
      • If no, go to Step 3.

  2. Check whether the LdapServer process is in the normal state.

    1. On the Alarm page of MRS Manager, check whether alarm ALM-12007 Process Fault is generated.
    2. Check whether the service name and host name in the alarm are consistent with those of LdapServer.
    3. Rectify the fault by following the steps provided in ALM-12007 Process Fault.
    4. In the alarm list, check whether alarm ALM-25000 LdapServer Service Unavailable is cleared.
      • If yes, no further action is required.
      • If no, go to Step 3.

  3. Collect fault information.

    1. On MRS Manager, choose System > Export Log.
    2. Contact technical support engineers for help, detail see technical support.
