Removing Inaccessible Objects in vSAN: A Step-by-Step Guide

As virtualization administrators, we have all faced the issue of inaccessible objects in our vSAN environment at some point. Whether it’s due to a host reboot or a virtual machine (VM) migration, these inaccessible objects can cause performance issues and hinder the overall functionality of your virtualized infrastructure. In this blog post, we will discuss how to remove such inaccessible objects in vSAN using various methods.

Before we dive into the removal process, let’s understand why these objects become inaccessible in the first place. When a VM is powered off or migrated, its associated objects, such as virtual disks and snapshot files, are not automatically removed. These objects remain in the vSAN cluster until they are explicitly deleted or marked for deletion. If these objects are not removed, they can cause performance issues and consume unnecessary space in the vSAN cluster.

Now, let’s explore the different methods for removing inaccessible objects in vSAN:

Method 1: Using the vSphere Client

One of the simplest ways to remove inaccessible objects in vSAN is using the vSphere client. Follow these steps:

1. Open the vSphere client and select the vSAN cluster you want to work with.

2. In the left navigation pane, click on “Objects” and then select “Inaccessible” from the filter menu.

3. Select all the inaccessible objects and right-click to select “Remove Objects.”

4. Confirm the removal of the objects by clicking “Yes” when prompted.

Method 2: Using PowerShell

PowerShell is a powerful tool for managing vSAN environments, and it can also be used to remove inaccessible objects. Here’s how:

1. Open PowerShell and connect to your vSAN cluster using the “Get-VsanObject” cmdlet.

2. Use the “Where-Object” cmdlet to filter the list of objects based on their accessibility status. For example, you can use the following command to find all inaccessible virtual disks:

“`

Get-VsanObject -Type VirtualDisk | Where-Object {$_.Accessibility -eq “Inaccessible”}

“`

3. Once you have identified the inaccessible objects, you can remove them using the “Remove-VsanObject” cmdlet. For example:

“`

Get-VsanObject -Type VirtualDisk | Where-Object {$_.Accessibility -eq “Inaccessible”} | Remove-VsanObject

“`

Method 3: Using vSAN API

If you are comfortable with programming and have experience working with APIs, you can use the vSAN API to remove inaccessible objects. Here’s an example of how to do it using Python:

1. Install the vSAN API client library for your preferred programming language.

2. Use the API to retrieve a list of all inaccessible objects in the vSAN cluster. You can use the “GetAllInaccessibleObjects” method to do this.

3. Loop through the list of inaccessible objects and use the “RemoveObject” method to remove each one.

Conclusion

Removing inaccessible objects from your vSAN environment is an essential task for maintaining performance and preventing storage consumption issues. In this blog post, we have explored three different methods for removing these objects: using the vSphere client, PowerShell, and the vSAN API. By following these steps, you can ensure that your vSAN cluster remains healthy and optimized.
