Upgrade a Single Node Cluster Environment with the ISO and Template

Important

• Upgrading to release 21.1 requires a system on 19.x, with security updates completed.

• While template installation and system upgrade takes approximately two hours at a single site, this may vary in accordance with your topology, number of devices and subscribers. Adjust your upgrade maintenance window to allow for your configuration.

• When upgrading from CUCDM 11.5.3 Patch Bundle 2 or VOSS-4-UC 18.1 Patch Bundle 2 and earlier, re-import specified CUC models according to your current version. Refer to the final upgrade procedure step.

• Tasks that are marked Prior to Maintenance Window can be completed a few days prior to the scheduled maintenance window so that VOSS support can be contacted if needed and in order to allow for reduce down time.

The standard screen command should be used where indicated. See: Using the screen command.

Validate the system health. Verify there are no pending Security Updates: security check	Done
Check system health. diag disk If there is any sign of the paths below are over 80% full, a clean-up is needed, for example to avoid risk of full logs occurring during upgrade. Clean-up steps are indicated next to the paths: / (call support if over 80%) /var/log (run: log purge) /opt/platform (remove any unnecessary files from /media directory) /tmp (reboot) Adaptation check - if the GS SME Adaptation is installed, check for duplicate instances of of GS_SMETemplateData_DAT and deleted any duplicates before upgrading to 21.2.	Done

Schedules, Transactions and Version Check (Maintenance Window)

Description and Steps	Notes and Status
Turn off any scheduled imports to prevent syncs triggering part way through the upgrade. Two options are available: Individually for each job: Log in on the Admin Portal as a high level administrator above Provider level. Select the Scheduling menu to view scheduled jobs. Click each scheduled job. On the Base tab, uncheck the Activate check box. Mass modify: On the Admin Portal, export scheduled syncs into a bulk load sheet. Modify the schedule settings to de-activate scheduled syncs. Import the sheet. Schedules enabled on the CLI: Run schedule list to check if any schedules exist and overlap with the maintenance window. For overlapping schedules, disable. Run schedule disable <job-name>.	Done
Check for running imports. Either wait for them to complete or cancel them: Log in on the Admin Portal as a high level administrator above Provider level. Select the Transaction menu to view transactions. Filter the Action column: Choose Status as “Processing” and then choose each Action that starts with “Import”, for example, “Import Unity Connection”. Click Search and confirm there are no results. If there are transactions to cancel, select them and click Cancel.	Done
Customized ``data/Settings`` If data/Settings instances have been modified, record these or export them as JSON. The modifications can be re-applied or exported JSON instances can be merged following the upgrade. See: Post Template Upgrade Tasks single node cluster (Maintenance Window). Version Record the current version information. This is required for upgrade troubleshooting. Log in on the Admin Portal and record the information contained in the About > Extended Version	Done

Pre-Upgrade Steps single node cluster (Maintenance Window)

Create a restore point and then restart server. As part of the rollback procedure, ensure that a suitable restore point is obtained prior to the start of the activity, as per the guidelines for the infrastructure on which the VOSS Automate platform is deployed. If you cannot restore the application from a restore point, your only recourse is to reinstall the application. When the backup is complete and you do not need the restore point for restore activities, you can remove it. After the restore point has been created, restart. Optional: If a backup is required in addition to the restore point, use the backup add <location-name> and backup create <location-name> commands. For details, refer to the Platform Guide.

Done

Description and Steps	Notes and Status
Before upgrading, check all services: Make sure no services are stopped/broken. The message ‘suspended waiting for mongo’ is normal on a fresh node. app status Verify the node is not in the ‘recovering’ state (stateStr is not RECOVERING) database config	Done

Upgrade single node cluster (Maintenance Window)

Description and Steps

Notes and Status

It is recommended that the upgrade steps are run in a terminal opened with the screen command. On the primary unified node: screen If upgrading from earlier than release 20.1.1: app upgrade media/<upgrade_iso_file> Note If upgrading from release 20.1.1, on the primary unified node, use the command: cluster upgrade media/<upgrade_iso_file> If upgrading from release 21.1 and up, on the primary application node, cluster upgrade media/<upgrade_iso_file> All unused docker images except selfservice and voss_ubuntu images will be removed from the system at this stage. Note: If the system reboots, do not carry out the next manual reboot step. When upgrading from pre-19.1.1, an automatic reboot should be expected. To remove a mount directory media/<iso_file basename> on nodes that may have remained after for example an upgrade, run: cluster run all app cleanup Manual reboot only if needed: system reboot If node messages: <node name> failed with timeout are displayed, these can be ignored. Since all services will be stopped, this takes some time. Close screen: Ctrl-a \

Done

Note

In order to carry out fewer upgrade steps, the updates of instances of the some models are skipped in the cases where:

• data/CallManager instance does not exist as instance in data/NetworkDeviceList

• data/CallManager instance exists, but data/NetworkDeviceList is empty

• Call Manager AXL Generic Driver and Call Manager Control Center Services match the data/CallManager IP

Post-Upgrade, Security and Health Steps single node cluster (Maintenance Window)

Description and Steps	Notes and Status
Verify the status: diag health	Done
If upgrade is successful, the screen session can be closed by typing exit in the screen terminal. If errors occurred, keep the screen terminal open for troubleshooting purposes and contact VOSS support.	Done
Complete all the security updates. security update The docker images selfservice and voss_ubuntu will be removed from the system at this stage. Note: If the system reboots, do not carry out the next manual reboot step . When upgrading from pre-19.1.1, an automatic reboot should be expected. Manual reboot only if needed: system reboot	Done

Database Filesystem Conversion single node cluster (Maintenance Window, if required)

Important

To check if the step is not required:

• Run drives list and ensure that the LVM storage shows for all converted database nodes under Volume Groups. If the output of the drives list command contains dm-0 - mongodb:dbroot, the step is not required. Refer to the drives list command output example below.

The database convert_drive command provides parameters that allow for a flexible upgrade schedule in order to limit system downtime.

When the database convert_drive command is run, the voss-deviceapi service will be stopped first and started after completion. The command should therefore be run during a maintenance window while there are no running transactions.

For a single node cluster system drive conversion, ensure the standalone parameter is used.

Description and Steps

Notes and Status

Shut down. Since all services will be stopped, this takes some time. system shutdown Create a restore point as per the guidelines for the infrastructure on which the VOSS Automate platform is deployed so that the system can easily be reverted in the case of a conversion error. Stop transactions from being scheduled. Run: database convert_drive standalone Note: this step may take a few hours. Wait until it completes successfully. database config Ensure that the storage engine for the database node shows as storageEngine: WiredTiger drives list Ensure that the LVM storage for the database node shows under Volume Groups In the example below, dbroot/dm-0 shows under Volume Groups, Logical volumes $ drives list Used disks and mountpoints: sdc1 - services:backups dm-0 - mongodb:dbroot Unused disks: none - if disks have been hot-mounted, it may be necessary to reboot the system Unused mountpoints: services:SWAPSPACE Volume Groups voss - 10.0 GB free, 60.0 GB total Physical volumes: sdd1 Logical volumes: dbroot/dm-0 - 50.0 GB
