Overview

You may need to reset the MGR node in some situations. For instance, after running a Health Check, you find that it has been up and running for a long time, e.g., more than a year, which is not recommended.

This article provides detailed information on the following topics:

• Performing a Hardware Check
• MGR Backup and Reboot Process

Prerequisites

• VPN access to the end user's system.
• Release 12.4.1
• Before any reboot, the hardware needs to be checked to ensure that no hardware issue affects the reboot.

Process

Performing a Hardware Check

1. As a root user, run the following commands:
   
   NOTE: The command can also be run with # hpssacli.
   
   

   # hpacucli ctrl all show config
   
   # hpacucli ctrl all show config detail

   
   (OR)
   
   

   # hpssacli ctrl all show config
   
   # hpssacli ctrl all show config detail

2. Inform the end-user about any failures (if found), so that they can check it before planning a reboot.

MGR Backup and Reboot Process

1. As a root user, stop the MGR process:
   
   

    # /usr/TextPass/bin/tp_mgr_stop

2. As a TextPass user, stop the STV processes:
   
   

   $ ps -ef | grep -I stv
   
   $ stv_poller --stop
   
   $ stv_poll_config_sync --stop
   
   $ stv_poll_collector --stop

3. Check the stv_db_importer logs. If no more message appears for a few minutes, stop stv_db_importer:
   
   

   $ stv_db_importer --stop

4. Back up the MGR database as a root user:
   
   

   # /usr/TextPass/bin/tp_mgr_backup -name=/backup/MGRDatabase.sql -verbose

5. Copy the MGR database backup file to another node or an external PC.
6. Copy the important files:
   1. As a TextPass user, copy the content of the /usr/TextPass/etc/ directory to an external drive.
   2. As a root user, copy the route and ifcfg files from the /etc/sysconfig/network-scripts/ directory to an external drive.
7. Save the output of the commands below to an external drive:
   
   

   # netstat -rn
   
   # ifconfig -a
   
   # cat /etc/fstab
   
   # cat /etc/mtab

8. Reboot MGR as a root user:
   
   

   # init 6

9. After booting up, check if the processes are running:
   1. Check the MySQL process as a root user:
      
      

      # service mysql status
      
      # ps -ef | grep -i sql

   2. Check the MGR process as a root user:
      
      

      # ps -ef | grep -i mgr

   3. Check the STV processes as a TextPass user:
      
      

      $ stv_self_test
      
      $ stv_poll_config_sync --status
      
      $ stv_poll_collector --status
      
      $ stv_db_importer --status
      
      $ stv_poller --status

10. If there is any NMM component running in MGR, check the status:
    
    

    $ tp_status

11. Check the system logs for any persistent error:
    
    

    $ tail -f /var/log/messages

Validation

1. Check the system logs for any persistent error.
2. Check the MySQL process as a root user:
   
   

   # service mysql status
   
   # ps -ef | grep -i sql

3. Check the MGR process as a root user:
   
   

   # ps -ef | grep -i mgr
