1   Introduction

This instruction concerns alarm handling.

1.1   Alarm Description

The alarm is raised when a manually created backup that is automatically exported has failed.

The possible alarm causes and fault locations are explained in Table 1.

Table 1    Alarm Causes

Alarm Cause	Description	Fault Reason	Fault Location	Impact
A manually created backup that is automatically exported fails	A Backup and Restore Management (BRM) automatically export of manually created backup to the configured backup storage server has failed	The external file storage fails to authenticate the SSH® File Transfer Protocol (SFTP) user used by the Managed Element (ME)	ME configuration	The export of manually created backup fails. The next successful export of manually created backup clears the alarm.
		The ME attempts to store SFTP files in a directory that does not exist in the external file storage	ME configuration
		The ME cannot reach the external file storage over SFTP	Network problems
		The SFTP user used by the ME does not have the permission to write files in the specified external file directory	External file storage directory permissions

Note:  

This alarm can appear as a result of a maintenance activity.

The alarm attributes are listed and explained in Table 2.

1.2   Prerequisites

This section provides information on the documents, tools, and conditions that apply to the procedure.

1.2.1   Documents

This instruction references the following document:

• Create Backup
• Data Collection Guideline

Note:  

This Operating Instruction describes only the System Data backup instructions. To apply them to a User Data backup, the user needs to navigate to the User Data backup manager, as follows:

>dn ManagedElement=<node_name>,SystemFunctions=1,BrM=1,BrmBackupManager=USER_DATA

1.2.2   Tools

No tools are required.

1.2.3   Conditions

Before starting this procedure, ensure that the following conditions are met:

• A BRM, Auto Export Manual Backup Failed alarm is raised.
• The address, SFTP username, and password for the external file storage are known.

  In this document, the username is hostuser1 and the password is hostuser1pw in host1.

• An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

2   Procedure

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

2.1   Analyzing Alarm

Select the appropriate action:

• If Additional Text contains Auto Export for <backup_Ttype> failed due to authentication failure, proceed with Section 2.2 Actions for Authentication Failure.
• If Additional Text contains Auto Export for <backup_type> failed due to directory not exist, proceed with Section 2.3 Actions for Directory Not Exist.
• If Additional Text contains Auto Export for <backup_type> failed due to server unreachable, proceed with Section 2.4 Actions for Server Unreachable.
• If Additional Text contains Auto Export for <backup_type> failed due to permission denied, proceed with Section 2.5 Actions for Permission Denied.
• If alarm message contains Auto Export for <backup_type> failed, proceed with Section 2.6 Actions for Undetermined Reason. This Additional Text is displayed when an automatic export of a manually created backup fails for an undetermined reason.

2.2   Actions for Authentication Failure

Do the following:

1. Navigate to the BrmBackupManager Managed Object (MO), for example:

   >dn ManagedElement=NODE06ST,SystemFunctions=1,BrM=1,BrmBackupManager=SYSTEM_DATA

2. Check that the SFTP user configured in the ME is the correct one to export backup files to the external file storage:

   (BrmBackupManager=SYSTEM_DATA)>show autoExportUri

3. Obtain the password associated to this SFTP user (contact the external file storage administrator, if necessary).
4. Enter Config mode:

   (BrmBackupManager=SYSTEM_DATA)>configure

5. Is it needed to change the configured username?

   Yes: Continue with the next step.

   No: Proceed with Step 7.

6. Change the configured username in attribute autoExportUri, for example:

   (config-BrmBackupManager=SYSTEM_DATA)>autoExportUri=s ftp://hostuser1@host1/home/hostuser1/

   Note:  

   Only SFTP URIs are supported. The syntax is sftp://<user_id>@<hostname_or_ip_address>/<remote_destination_directory>

   
   
7. Change the configured password, for example:

   (config-BrmBackupManager=SYSTEM_DATA)>autoExportPassword="hostuser1pw" cleartext

8. Commit the changes:

   (config-BrmBackupManager=SYSTEM_DATA)>commit

9. Create a backup.

   For information on how to create a backup, refer to Create Backup.

10. Is the alarm cleared?

    Yes: Proceed with Step 13.

    No: Continue with the next step.

11. Perform data collection, refer to Data Collection Guideline.
12. Consult the next level of maintenance support. Further actions are outside the scope of this instruction.
13. Job is completed.

2.3   Actions for Directory Not Exist

Do the following:

1. Check which directory is meant to be used in the external file storage for export of backup files (contact the external file storage administrator, if necessary).
2. Navigate to the BrmBackupManager MO, for example:

   >dn ManagedElement=NODE06ST,SystemFunctions=1,BrM=1,BrmBackupManager=SYSTEM_DATA

3. Enter Config mode:

   (BrmBackupManager=SYSTEM_DATA)>configure

4. Change the directory configured in the ME:

   (config-BrmBackupManager=SYSTEM_DATA)>autoExportUri=s ftp://hostuser1@host1/home/hostuser1/

   Note:  

   Only SFTP URIs are supported. The syntax is sftp://<user_id>@<hostname_or_ip_address>/<remote_destination_directory>

   
   
5. Commit the change:

   (config-BrmBackupManager=SYSTEM_DATA)>commit

   In this document, the external file system is called host1.

2. Can the external system be reached with a delay less than 10 seconds?

   Yes: Continue with the next step.

   No: The network can have a configuration fault. Request the network administrator to act on the fault. Proceed with Step 7.

3. Create backup.

   For information on how to create backup, refer to Create Backup.

4. Is the alarm cleared?

   Yes: Proceed with Step 7.

   No: Continue with the next step.

   >dn ManagedElement=NODE06ST,SystemFunctions=1,BrM=1,BrmBackupManager=SYSTEM_DATA

2. Check the SFTP user and the directory configured in the ME:

   (BrmBackupManager=SYSTEM_DATA)>show autoExportUri

3. Has the SFTP user proper write permissions in the external file storage directory (contact the external file storage administrator, if necessary)?

   Yes: Proceed with Step 6.
