Nutanix Async DR - Basic setup and Protection Domain Configuration

The Term "Asynchronous Replication" itself means to store and forward approach, in another word, writes data to the primary storage array first and then commits data to be replicated to replication targets based on a specific schedule, 

Nutanix provides native snapshots Per-VM or per volume group, by using Async DR feature the RPO would be (up to 1-hour RPO), the snapshot schedule should be equal to your desired RPO, you can set your schedule to 1 Hour or more,

Before you start you need to make sure that your network connectivity between both sites is healthy and both sites are reachable from the other site,

From the Main site, Prism interface click on the main tab and go to Data Protection and click on it

Nutanix Async DR - Recover from a Disaster

In the previous post we went through the steps of configuring Main site and DR site as a remote site to each other and create a protection domain including which VM's will be protected from Main site to DR site, details on the following link:

Async DR - Basic setup and Protection Domain Configuration (Click Here)

In this post we will go through the steps of Recover from a Disaster for protected VM's from Main site to DR site,

In this scenario we assume that we lost the Main site (No access to Main Site anymore) and we need to recover from the DR site,

From DR Site go to Data Protection page, select the protection domain you need to recover and select "Activate"

Nutanix Async DR - Planned Failover

In the previous post we went through the steps of configuring Main site and DR site as a remote site to each other and create a protection domain including which VM's will be protected from Main site to DR site, details on the following link:

In this post we will go through the steps of a planned migration for protected VM's from Main site to DR site,

As first step we need to double check that every thing looks normal in DR site, go to Data Protection page to make sure that the protection domain is listed, you will find the protection domain but not as active and if you check the VM page you will not find the VM's as it is currently running in the main site.

Nutanix Async DR - Cloning VM from Snapshot to DR Site

In the previous post we went through the steps of configuring Main site and DR site as a remote site to each other and create a protection domain including which VM's will be protected from Main site to DR site, details on the following link:

In this post we will go through the steps of Cloning protected VM to DR site,

In this scenario we have normal access to Main site and the original VM is working with no issues but we need to clone another copy for the same VM from the DR site.

From the DR Site go to Data Protection page and select the protection domain from the list, once selected you will be able to select "Local Snapshot", select the version you want to restore (Clone) your VM from, for example if you set your replication schedule every 1 hour with retention of 10 last copies then you will find here 10 versions from the last 10 hours,
Select your snapshot and click on "Restore"!

Adding New Disk to Linux VM running on Nutanix AHV (Part-2: Creating new Volume group and new Logical Volume)

In the first post, Part-1:Extending Current Volume group and Logical Volume 

We extended the current Volume group and Logical Volume with the new added disk to the VM, 

In this post we will go through How to create a new Volume Group and new Logical Volume and we will mount it to a new mounting point,

To create a new Volume Group and new Logical volume we will start with same steps like what we did in the first post:

-       Add the new disk from Nutanix Prism

-       FDISK

-       Physical Volume Create using “pvcreate”

Next step we will run the command “vgcreate” give a new name to the new Volume Group

Adding New Disk to Linux VM running on Nutanix AHV (Part-1: Extending Current Volume group and Logical Volume)

In this post, I will go through the Steps to Add a New Disk to Linux VM running on Nutanix AHV,

In my example, I have Oracle Linux 6.5 VM running with one assigned disk with 100 GB and we want to add another disk with 350 GB, first let’s check the status of the available Volumes with the command “pvscan”

Note that you have only one Volume with 100 GB

Now let’s List all available disk Partitions by running the command: Ls /dev/sd*

The command will list all available hard disks

Invisible Infrastructure: In-Place Hypervisor Conversion

The Most powerful Infrastructure is the Infrastructure you don’t see or interact with, in another word the “Invisible Infrastructure”

Single Interface that combined Compute, Storage, DR, Cloud connect and even the HYPERVISOR and more, we are talking about the future of the IT “Enterprise Cloud” we are talking about NUTANIX.

One of the very cool new features in the new edition of AOS 4.6 is the ability to convert the Hypervisor running in your Cluster, in this blog post we will go through the conversion from ESXI to AHV and from AHV to ESXI,

The beautiful part that every thing is automated and GUI even the Guest VMs are converted to the hypervisor target format with no effort,

Let’s start with the first step after having the NUTANIX Cluster up and running ESXI hypervisor, Click on “Convert Cluster”

Read the notes and consider the requirements then click on “AHV”
