Perform Live Software Upgrade of Application

...

1. Login to the CLI on the active server.
   
   

2. At the CLI prompt of active server, start the LSWU using the following CLI command.


   Code Block
   language none title Example
   admin@WFDSBC01a> request system serverAdmin WFDSBC01b startSoftwareUpgrade package sbc-V05.0001.00-R000.x86_64.tar.gz This command will start live software upgrade. Do you want to proceed (yes/no): <yes> Proceeding result success reason Success from: WFDSBC01b

    

   Note
   icon false
   The package name must not contain the package path.

3. Once the upgrade starts, monitor the status using the following CLI command.



   Code Block
   language none title Example
   admin@WFDSBC01a> show table system serverSoftwareUpgradeStatus NAME UPGRADE STATUS ---------------------------- WFDSBC01a pendingUpgrade WFDSBC01b upgrading

   Note
   At the beginning of the upgrade, server is rebooted and disk partitioning is done automatically that takes approximately 15 to 20 minutes. Do not hit the power button or restart the server during this time. Open the JViewer console to watch the progress of upgrade.

4. Verify the sync status is in syncCompleted state, using the following CLI command.


   Code Block
   language none title Example
   admin@WFDSBC01a> show table system syncStatus SYNC MODULE STATUS ------------------------------------------- Policy Data syncCompleted Disk Mirroring syncCompleted Configuration Data syncCompleted Call/Registration Data syncCompleted

5. Verify the software upgrade status is in Upgraded state, using the following CLI command.


   Code Block
   language none title Example
   admin@WFDSBC01a> show table system serverSoftwareUpgradeStatus NAME UPGRADE STATUS -------------------------------- WFDSBC01a pendingUpgrade WFDSBC01b upgraded

   Note
   This process takes approximately 45 minutes to complete on a single server.

6. Verify the system server status using the following CLI command.

   Code Block
   language none title Example
   admin@WFDSBC01a>> show table system serverStatus MGMT PLATFORM APPLICATION REDUNDANCY APPLICATION UP LAST RESTART NAME HW TYPE SERIAL NUM PART NUM VERSION VERSION ROLE UP TIME TIME REASON SYNC STATUS ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- WFDSBC01a SBC 5200 2044090074 821-00430 V04V05.0200.00R00002R000 V04V05.0200.00R00002R000 active 0 Days 02:44:22 0 Days 02:43:1104 systemRestart syncCompleted WFDSBC01b SBC 5200 2052090007 821-00430 V05.0001.00R000 V05.0001.00R000 standby 0 Days 00:13:02 0 Days 00:07:23 softwareUpgradeOrRevert syncCompleted

7. Once the WFDSBC01b state changes to upgraded, proceed with upgrading the next server.

8. Upgrade the next server using the following CLI command.
   
   

   Code Block
   language none title Example
   admin@WFDSBC01a> request system serverAdmin WFDSBC01a startSoftwareUpgrade package sbc-V05.0001.00-R000.x86_64.tar.gz This command will start live software upgrade. Do you want to proceed (yes/no): <yes> Proceeding result success reason Success from: WFDSBC01a [ok][2015-01-20 05:37:04]

    

9. This causes an automatic switch-over whereby the active role is assigned to the original standby server (WFDSBC01b) which is already upgraded.
   
   

10. Once the upgrade starts, monitor the status using the following CLI command on the new active server:.


    Code Block
    language none title Example
    admin@WFDSBC01b> show table system serverSoftwareUpgradeStatus NAME UPGRADE STATUS ---------------------------- WFDSBC01a upgrading WFDSBC01b upgraded

     

    Note
    At the beginning of the upgrade, server is rebooted and disk partitioning is done automatically that takes approximately 15 to 20 minutes. Do not hit the power button or restart the server during this time. Open the JViewer console to watch the progress of upgrade.

    
    

11. Verify whether both the servers are upgraded using the following CLI command. 


    Code Block
    language none title Example
    admin@WFDSBC01b> show table system serverSoftwareUpgradeStatus NAME UPGRADE STATUS ---------------------------- WFDSBC01a upgraded WFDSBC01b upgraded

12. After both the servers get upgraded and is in sync with its peer, an automatic switchover may happen.

    Note
    On all the SBC platforms other than the SBC 7000, an automatic switchover happens at the end of upgrade from pre-5.0 releases.

     

     

13. Verify the Live Software Upgrade status is in UpgradeDone state and primary and secondary upgrade status is in upgraded state. Use the following CLI command.
    
    

    Code Block
    language none title Example
    admin@WFDSBC01a> show table system softwareUpgradeStatus state upgradeDone; previousState upgrading; upgradeStartTime "Fri JulAug 3 11:44:40 20152016"; revertStartTime n/a; package /opt/sonus/external/sbc-V05.0001.00-R000.x86_64.tar.gz; rpmName /opt/sonus/staging/sbc-V05.0001.00-R000.x86_64.rpm; upgradeScript /opt/sonus/staging/sbxUpgrade.pl; revertScript /opt/sonus/sbxRevert.pl; reason successfulCompletion; oldRelease V04V05.0200.03R00002R000; newRelease V05.0001.00R000; primaryUpgradeStatus upgraded; secondaryUpgradeStatus upgraded;
