2 Procedure

This section describes the procedure to follow when this alarm is raised.

2.1 Actions for "applyConfig action is ongoing"

If the alarm is raised, do the following:

Steps

  1. Check the status of the applyConfig administrative action. Refer to CUDB Node Configuration Data Model Description for more information.
  2. Wait until the value of the state attribute of applyConfigStatus is FINISHED.
  3. Perform the backup again.

2.3 Actions for "Backup with the same name already exists"

If the alarm is raised, do the following:

Steps

  1. Check if a backup file with the same name already exists:
    Go to backup directory with cd /cluster/home/cudb/swbackup, enter ll or ls command for display content of directory, and check if that backup with the same name already exists.
  2. Perform the backup again using a name that is not already in use.
  3. If the alarm does not cease, contact the next level of maintenance support. Further actions are outside the scope of this Operating Instruction..

2.4 Actions for "Internal fault"
