Case: VCSA 7.0 - Update Planner "Unexpected error occurred while fetching the updates"

 I am getting this error message for VCSA 7.0 - Update Planner "Unexpected error occurred while fetching the updates". Also getting errors under "Interoperability" - Unexpected error occurred while fetching the interoperability details.

Update Planner is part of vSphere Lifecycle Manager used to facilitate vCenter Server updates. When you use the Update Planner in the vSphere Client, you might see: Unexpected error occurred while fetching the updates. So this article offers 2 ways to solve the error in vCenter 7.

Way 1. Fix vCenter 7 unexpected error occurred while fetching the updates

You could try SSH into VCSA 7.0 and reboot VCSA. To solve the “non-operational" error, you could follow these steps as below.

1. SSH to your VCSA 7.x appliance

If you don't have SSH access enabled, temporarily turn it on by following along by using VAMI, which in my lab meant browsing to https://vcsa.lab.localhost:5480

2. Type your credentials, root username and password

3. You likely don't have BASH shell active by default, so when prompted, just type:


4. You'll now see a command like this

root@vcsa [ ~ ]#

5. Next, delete this one file, you can copy-and-paste the following 1-line command into your SSH session if you'd like:

rm /etc/applmgmt/appliance/software_update_state.conf

6. Try the upgrade again.

Way 2. Invoke the API to solve vCenter 7 update planner error

The issue also occurs when you use a custom HTTPS port that prevents you from running interoperability reports by using the vSphere Client.

The Workaround is to manually invoke the API. So in this article, I will introduce the necessary steps to enable you to begin calling APIs.

1. Create a session ID.

2. Include the session ID returned in the above call using an HTTP header as follows:

3. You have been authenticated and have retrieved your API session ID. Then to create your first virtual machine using this API.

4. Once your VM is created, you can get the details of your VM by passing VM identifier.

The issue with update planner is known to VMware. VMware are trying to solve it. If you are worried about losing data due to vCenter upgrade, you should backup vCenter first for better protection.

Batch backup VMs on vCenter for better data protection

As we know, vCenter Server provide a scalable, extensible platform for centralized management of VMware vSphere environments. With a single vCenter Server, you can manage up to 1,000 hosts and 10,000 running virtual machines. However, vCenter Server does not provide the feature of virtual machine backup.

So here I introduce you to a VMware backup software - AOMEI Cyber Backup, it automates the backup process of multiple VMs managed by vCenter Server, and sends email notifications if there's an error.

Centralized Backup: create complete and independent image-level backup for VMware ESXi and Hyper-V VMs without install Agent VMs.
Batch vSphere Backup: batch backup large numbers of VMs managed by vCenter Server, or multiple VMs on a standalone ESXi host.
Different Storage Locations: backup to local drive, or network destinations like NAS.
Auto VM Backup: schedule VM backups and run it automatically by daily, weekly, and monthly with email notifications.
Restore VM Easily: restore immediately available VMs from any selected restore points to original or new location without any complicated configuration or reinstallation.

AOMEI Cyber Backup supports VMware ESXi 6.0 and later versions. Next, I will show you how to batch backup VMs managed by vCenter Server with AOMEI Cyber Backup. You can click the following button to download the 30-day free trial.

4 Steps to batch backup VMs on vCenter Server

1. Bind Devices: Access to AOMEI Cyber Backup web client, navigate to Source Device > VMware > + Add VMware Device to Add vCenter or Standalone ESXi host. And then click  > Bind Device.

2. Create Backup Task: Navigate to Backup Task > + Create New Task, and select VMware ESXi Backup as the Backup Type.

3. Set Task NameDeviceTargetSchedule, and Cleanup as needed.

  • Task Name: you can chance the task name or use the default name with an ordinal.
  • Device: batch select large numbers of VMs managed by vCenter Server for centralized backup.
  • Target: select to back up to a local path, or to a network path.
  • Schedule (optional): offers full / incremental / differential backup methods and flexible time type for backup.

  •  Backup cleanup (optional): automatically delete the old backups and retain the new VM backups.

  • Run Backup: Click Start Backup and select Add the schedule and start backup now, or Add the schedule only.

4. Restore: You can create a new VM by hitting Restore button, and it allows you to restore VM to original/new location directly from any selected backups, which saves the trouble of re-configuring the new VM.
