This document outlines the procedures for upgrading Jetstream DR for AVS.
Introduction
The software upgrade process can involve updating the MSA, Plugin, DRVA, RocVA, RVM, and Cluster followed by a post-upgrade clean-up. Every version upgrade does not necessarily upgrade all the components. To ensure a smooth upgrade experience, adhere to the prerequisites listed below.
...
| Info |
|---|
The time required to complete the upgrade process is affected by various external factors beyond the control of JetStream Software (e.g., enter/exit ESX host maintenance mode); therefore, it is not possible to know how long a software upgrade will take before the operation has begun. Schedule your upgrade calendar accordingly. |
Prerequisites
The following prerequisite conditions must be met before attempting to upgrade JetStream DR for AVS:
Select a time window to perform the upgrade when the system is less loaded.
Verify and confirm the integrity of all JetStream DR components, ensuring they are operational and error-free.
Before proceeding, check and resolve any previously unsuccessful update tasks.
Execute the clean-up operation using the command
js_upgrade.py clean -vbefore initiating a new upgrade.Validate and ensure all ESXi host IO Filter storage/VASA providers are online: vCenter > Configure > Storage Providers.
Ensure there are no active Affinity rules (ESXi) that could affect the host's ability to enter maintenance mode.
Verify the health of all vSAN objects. Navigate to: vSAN Cluster > Monitor > vSAN Skyline Health - Data - vSAN Object Health.
Confirm no resync operations are currently running in the vSAN cluster. Resyncing can affect the maintenance mode process. Monitor ongoing resync activities at: vSAN Cluster > Monitor > Resyncing Objects.
Temporarily suspend any scheduled backups (snapshot-dependent) during the DRVA upgrade activity to prevent backup failures (snapshots taken during this time will fail).
Upgrade Procedure
The AVS cmdlet Update-JetDR is used to perform the JetStream DR software version upgrade. This cmdlet manages upgrading JetStream DR components to their latest versions. Additionally, it includes a “resume” option that allows continuation of a previously failed upgrade task.
Run Command
Log in to Azure portal and select the desired Azure VMware Solution private cloud. Click Run command underOperations in the left navigation menu.
...
Once the cmdlet has been initiated, monitor its status under Run execution > Information.
(Click the Refresh option to update the screen to show its current status.)

Upgrade Process Steps
The upgrade process will perform the following steps:
...
| Warning |
|---|
The AVS Run command may time out after 60 minutes. This is an AVS limitation. |
Upgrade Resume
| Note |
|---|
The Resume option should only be used if a previous attempt to execute Update-JetDR has failed.

The following screenshot highlights the “Resume” option of the Update-JetDR cmdlet:
...
Upgrade Conclusion
At the conclusion of the software upgrade, the script should gracefully exit with Run execution status indicating“Succeeded.”
Additionally, make sure there are no error messages present under the Error tab.
...
Navigate to: Datacenter > Configure > Jetstream DR > Appliances.
For each DRVA:
Check the Status
Check for any Child Alerts
Check the Software Version
...
IO Filter Synchronization
If the cluster has been upgraded to the latest version but some hosts still report old IO Filter versions, use the Resolve-Clusterissue cmdlet to resolve the discrepancy.
...
How to Check the IO Filter Version
Navigate to: Datacenter > Configure > Jetstream DR > Configurations.
Note the current software version of the cluster and if it has any warning.
Click the Host Details link to review the details of the individual hosts of the cluster.
