@bezeddinThe model which I am using is XC6320-6 which is different from rest of the Dell XC models. In this model I am not able to see the SD card.

Please find the screenshot.

PS: I am following the doc "Rapid Appliance Self Recovery (RASR) for Dell EMC XC Series Web-Scale Hyperconverged Appliance – Windows 2012 R2
For the Dell EMC XC Series XC430-4, XC630-10, XC630-10AF, XC730xd-12, XC730xd-24, XC730xd-12c, XC730-16G, XC6320-6 and XC6320-6AF

Re: Dell XC 6320 - How to reimage the CVM ?

@bezeddinI did that and lost my CVM. After I found that the document says the below Smiley Sad.

"WARNING: Do not boot to the Embedded Disk Storage Device on XC6320 nodes. This can lead to erasing the operating system and the Nutanix CVM. For recovery on XC6320 refer to Using RASR for Dell EMC XC Series for XC6320."

 

Now I am not able to launch RASR, I think I have lost the recovery partition. One strange, still I am able to see my ESXi and Broken CVM which keeps rebooting.

 

There is nowhere I can see the document to launch RASR without USB or do re-imaging (Factory reset). Even for factory reset I need RASR.

Re: Dell XC 6320 - How to reimage the CVM ?

@bezeddinHi,

Finally we got the Nutanix cluster up and running.

We did the following.

1. Re-imaged XC nodes via Phoenix.iso

2. Once we re-imaged the nodes were available to join the cluster

3. We used the foundation applet to discover the nodes and installed the cluster

 

Now I got a question reg upgrade. We installed the NOS version 4.7.5.2 and would like to upgrade to 5.0.2.  Can you point us in the right direction for this version?

 

Cheers,
Jaffer

Got to the settings wheel in Prism and click on Upgrade Software.  In the available compatible versions section choose 5.0.2 and download.  After it's downloaded, go back to the same place and run the pre-upgrade check.  If that finishes successfully, click on upgrade, go grab a drink, and watch the running task (if you want).  

 

You should loose connectivity to Prism or get a timeout at least once when the CVM that you are watching through reboots.  As long as you are connecting through the cluster ip address, refresh the page and it should come back up.  The whole process on 4 nodes or less should take between 15-30 minutes.

 

Enjoy.
