The server is a Dell PowerEdge R640, and it has been re-branded back to a standard Dell R640 in iDRAC - the installation is only for Lab/testing, not for production.I have tried several installation combinations:Latest available AOS/AHV versions — although I understand these may not be supported on this older hardware Latest supported combination I could find for this platform: AOS 6.5.1.8 AHV 20220304.336 In all attempts, Foundation fails during the installation with the following error:CRITICAL svm_rescue: No suitable SVM boot disk foundAOS installation failed. Reason: NoneThe node boots successfully into Phoenix, downloads the AOS package, AHV ISO, Anaconda bits and driver package, but fails when the CVM/SVM installation begins.Model: Dell PowerEdge R640 / R640-10Boot mode: Legacy BIOSSecure Boot: DisablediDRAC: iDRAC9Storage controller: HBA330Boot device: Dell BOSS-S1 RAID1BOSS virtual disk size: approx. 240 GBDat

Dear experts,I have successfully installed Nutanix Community Edition (CE) 2.1 on VMware Workstation, but I'm facing a networking issue.Environment Platform: VMware Workstation Nutanix Version: Community Edition 2.1 Allocated Resources: 65 GB RAM 8 vCPUs Installation completed successfully, and I can log in to Prism without any issues.ProblemAfter logging into Prism, I checked the Network Configuration, but the Virtual Switch list is empty. Because no virtual switch is available, I'm unable to create a VM since there is no network to attach.What I've CheckedInstallation completed without any reported errors. Prism is accessible through the management IP. The virtual switch is not created or displayed under the networking section.Has anyone experienced this issue with CE 2.1 running on VMware Workstation?

An administrator is deploying an NC2 cluster on AWS in the us-west-2 region. A VPC, management subnet, and a VM subnet are already created in the target region.The management subnet has a local route and a route to the Internet. The VM subnet has a local route and a route to the NAT gateway. During the deployment, the management subnet appears in the drop-down list in the Create Cluster wizard, but cannot be selected.What is the cause of this problem?The subnet has an IPv4 CIDR block but does not have an IPv6 CIDR block.The subnet has a direct route to an Internet gateway.The subnet has both an IPv4 CIDR block and an IPv6 CIDR block.The subnet does not have route to a Site-to-Site VPN connection through a virtual private gateway.

Hi Team,I am trying to set up a small Nutanix lab environment on VMware ESXi for learning and testing Prism Central integration.However, I do not have access to the Nutanix Support Portal, so I am unable to download the Prism Central OVA file.I checked multiple links but they all redirect to the support portal login page.Is there any:Community / trial download for Prism Central OVA (ESXi format), or Alternative way to obtain a POC/evaluation copy for lab use?I am not using this for production, only for learning and testing.Any guidance would be appreciated.Thank you.
