Note

Please remember to do backup first, before installing an update in case of any problems that may occur. To do backup please follow instructions below.

 

Please perform the following steps to create a backup using the Web Interface:

  1. Open the Administration GUI

  2. Choose Backup (left side menu) and ensure that all backup options are ticked as shown in the screenshot above

    Image Removed

  3. Admin GUI > System > Backup

  4. Choose Create new backup including components and tick persistent backup. The backup creation starts immediately in the background. It will appear in the list of available backups later.
  5. Download the created backup by choosing Image Added  and store the created backup on an external drive
. To download click on the disk icon in the row of the created backup.
  1.  
Info

SONARPLEX generation 5 contains new features which aren´t available in SONARPLEX generation 4. This means that the SONARPLEX generation 5 does not support generation 4 backups anymore.

In order to perform a rollback, a backup should must be created before updating to generation 5.

Enable Large Installation Tweaks

Please enable Use large installation tweaks before the upgrade, this option deactivates automatic backups upon startup. This is highly recommended as otherwise the upgrade can take a long time and most installations can easily rely on SONARBACKUP or the regular auto backups.

To enable the large installation tweaks:

  1. Open the Admin GUI > Configuration > System > Load Configuration
  2. Activate Use large installation tweaks
Info
You can activate this option whenever you are doing maintenance tasks and want to avoid the automatic start up backup. Of course you can activate it afterwards again.

Disable Notifications

Notifications should be disabled globally during the upgrade process to avoid any unnecessary notifications or even possible alert floods. 

Disable notifications globally:

  1. Open the Web GUI > Status > Processes
  2. Choose  Disable notifications and press Commit in the next screen
Info

This disables the notifications persistently, so even reboots and Monitor process restarts will keep the notification system disabled. Check Re-Enable the Notifications after the upgrade.

Upgrade Installation

Upgrade to SONARPLEX version 4.2.x

Info

You must download the SONARPLEX image(s) for the following upgrades form the azeti Portal specifically for your device(s), see the previous section Individual File Download for details.

To upgrade to 4.2.x do the following:

  1. Open Admin GUI > Update
  2. Choose Manual Update and Browse to select the SONARPLEX version 4.2.0 image file (extension .aup) you downloaded previously
  3. Select the update icon  to start the update, the SONARPLEX will reboot which takes up to 10 minutes

Install necessary updates for 4.2.x

To allow the upgrade to SONARPLEX Generation 5 you must install a patch.

Info
Minimum patch level for the upgrade from SONARPLEX 4.2 is base 7, named update-4.2.0b-base-7.tar.

Even if you decide to stay with SONARPLEX release 4.2 the patch fixes some major bugs and it is recommended to be installed.

After the SONARPLEX Upgrade

SONARPLEX 5 is a major release and thus some minor system configuration changes must be done right after the upgrade. 

Updating the LOAD Configuration

The following step assures that the global LOAD Configuration is properly updated and is mandatory.

  1. Open Admin GUI > Configuration > System > Load Configuration
  2. Choose  to save the current configuration and apply it with the following 

Configure the global Log Level

A whole new logging framework was introduced with the upgrade. See Admin GUI > Configuration > System > Logging Configuration.

 By default the Debug log level is set to OFF. We recommend turning it to INFO for all hardware types except the azeti NG.

Note

The azeti NG runs on SD flash storage and debug log levels can lead to decreased lifetime of the storage due to large amounts of write operations through logging. Therefore leave the Debug log level set to OFF.

Flush the Retention File

To warrant a consistent status among the old and new plugins, delete the retention file. 

Info

Deleting the retention file leads to a flush of all status information, this will set every host and service object into state PENDING. This is expected and the objects will be checked during the normal check intervals and return into a non-PENDING state.

Deleting the retention file:

  1. Open Admin GUI > Status > Monitor
  2. Choose  Delete state retention file (read online help before using), the Monitor process will be restarted automatically

Flush the Mail Queue

It is possible that during the upgrade system messages are created and stored in the email queue. Those would be sent out whenever you enable the SMTP configuration and you can flush those if you don't want to receive such mails from the upgrade.

Flushing queued e-mails:

  1. Open the Admin GUI > System > Email Queue
  2. Choose  Delete all messages in queue and press OK

Re-Enable the Notifications

When all upgrade steps are done and the system behaves properly, it is save to enable the notifications again. Check that not too many service and host checks are in Non-OK states to avoid notification floods.

Enable notifications globally:

  1. Open the Web GUI > Status > Processes
  2. Choose  Enable notifications and press Commit in the next screen
