Foundation with Phoenix - reborn from ashes

Warning: Use of Phoenix to re-image or reinstall AOS with the Action titled "Install CVM" on a node that is already part of a cluster is not supported by Nutanix and can lead to data loss. Use of Phoenix to repair the AOS software on a node with the Action titled "RepairCVM" is to be done only with the direct assistance of Nutanix Support. Use of Phoenix to recover a node after a hypervisor boot disk failure is not necessary in most cases. Please refer to the Hardware Replacement Documentation for your platform model and AOS version to see how this recovery is automated through Prism. What is Phoenix? Phoenix is an ISO-based installer that you can use to perform the following installation tasks on bare-metal hardware one node at a time: Configuring hypervisor settings, virtual switches, and so on after you install a hypervisor on a replacement host boot disk. This option does not require you to include AOS and hypervisor installers in the Phoenix ISO image. Installing the Controller V

PC Scaleout migration options

I just deployed Prism central scale out on my ESXi cluster and see that the two additional PC appliances have an iso mounted to their CDROM drives. Does this need to stay connected? I’d like to spread these 3 appliances across different datastores. (And ideally, I’d like to move these across sites but I understand that this is a future feature: https://next.nutanix.com/product-ideas-61/multi-cluster-scale-out-prism-central-28305)

Nutanix snapshot how he lives together with esxi ?

Hello, I need to understand how nutanix snapshot he lives together with vmware snapshot. It's possible to protect VM with Nutanix snapshot although maybe some users make snapshots from vmware side ? Do they work together ? are there any contraindications or special attentions ? Do they not interfere with each other? I think only be careful not to interfere any restore snapshot from nutanix side with any backup/snapshot made vmware side (aka veeam) ? Thanks Manuel

How Alert Auto Resolve Works

I'm new to Nutanix and learning as I go. I'm looking at monitoring and alerting and noticed an alert that has not auto resolved. The specific alert is: Node Marked To Be Detached From Metadata Ring I've run ALL NCC Health Checks on the node and it comes back healthy. This alert is set to auto resolve but for some reason will not resolve. I check policy and the auto-resolve checkbox is checked. I did some digging and found a KB article (#000004269) for alert_auto_resolve_helper. I read about this NCC check and I don't see this as an available check in my environment. Any thoughts and tips are appreciated. Thanks!

A question about NearSync DR

Hi, My customer is considering leveraging NearSyncDR for their production clusters. Looks like I have to explain to them how NearSync should be configured and how it works to match their needs for future plan. As it matters, I have dived around Nutanix portal for some documents related to this technology but nothing explains clearly why it should run by its behavior in the example below: In the case I configured a schedule that repeats 1 min and retention policy of local cluster for 5 days, NearSync will work as that it will: Create a snapshot per minute and retain it for 15 minutes. Create hourly snapshots and retain for 6 hours. Create daily snapshots and retain for 5 days. So the question is if a snapshot A was created and deleted in 15 mins later, in the case user wanted to use this snapshot A to recover his file, how did he do? Is snapshot retaining time able to be changed by any command?

Cost Vs Performance 10Gb BaseT vs 4@ 1Gb BaseT

Hi, I'm planning a 3 node Lenovo 2320-E node. The most it will ever grow, is to a 4 node. Each node has a 4 x 1/10Gb BaseT network card (IMM/IPMI) connection is separate. The max number of VM's will probably never exceed 16 (Windows 2008R2/Windows 2016 ) The priority of importance in this case is: Reliability Lowest Cost Performance Network Config Option 1 (1 switch 1 GB ports only): Purchase 1 switch with dual hot-swap power supplies. (Not to jinx myself, but switches have a low fail rate) Setup each node as balance-slb, with 4 x 1Gb BaseT Network Config Option 2 (2 switches 1GB ports only) Purchase 2 switches, each with a single power supply Setup each node as balance-slb, with 4 x 1Gb BaseT Network Config Option 3 (1 switch with both 1 & 10Gb BaseT) Purchase a switch that supports mixed 1 & 10Gb BaseT ports Setup each node as balance-slb and use 2 x 10Gb (of the 4 ports) My understanding of balance-slb is I will have 4Gb of throug

Getting started with Nutanix

Hi Friends, It's nice joining you in this wonderful community. I'm Ridwan Oladipupo from Algorism Limited, Nigeria. I'm representing my company as a System Engineer saddled with the responsibility of handling the technicalities of Nutanix during POC. Please I'm absolutely new to the system, I've started with nutanix school, but I felt that is not sufficient enough to get the Job done. I need to get with the guys doing the job. I would be glad if anyone can volunteer to mentor me on this solution. Thanks in anticipation.

Setting up and troubleshooting remote authentication LDAP/AD

Remote authentication is one of those things that once set up correctly just work. We do not notice it, we simply put in our credentials and use it.It takes some understanding and a tiny bit of thinking ahead when mapping AOS roles and permissions to LDAP/AD users and user groups.So where to start?First, follow Prism Element Security Guide: Configuring Authentication to set up remote authentication.Run NCC Health Check: ldap_config_check.For any issues leverage KBs:KB-2066 Unable to Log In to the Prism web console using Group LDAP authenticationKB-3363 Prism: Troubleshooting LDAP Issues for Prism Log On For those of you PowerShell fans there is a little bit of CLI available:PowerShell Cmdlets Reference: LDAPConnection PowerShell Cmdlets Reference: Domain

Latest Powershell CmdLets for 5.11

There appears to be an issue with the latest Powershell Cmdlets for Version 5.11 that reports itself as Version 5.1.1 (not 5.11) so there is a mismatch. This will bring up a Warning dialogue box asking you if you want to continue with this mismatch (Cluster Version 5.11 and CmdLets Version 5.1.1). This can affect any Powershell Automation Scripts you have running that will be waiting for user intervention! You can change the Nutanix Connection method to Force the Connection using the following syntax: Connect-NTNXCluster -Server "Your server here" -UserName "Your user" -Password "Your password" -AcceptInvalidSSLCerts -ForcedConnection Note: It is the ForcedConnection that enables the bypass of the mismatch for your scripts. Hopefully they will update the Version with the next iteration of the Cmdlets without the apparent typo of 5.1.1 instead of 5.11. Please feel free to "Like" to mark as "Best Answer" Kind Regards Andy @andymlloyd

REST API Authentication

Nutanix REST API gives flexibility to a developer or an administrator to create scripts which can execute administrative jobs on a Nutanix cluster. Using the API, you can request information about different entities in the cluster or even change some configuration. Everyone at the end of the day wants to make sure that their infrastructure is fully secure.  So what about Authentication? What kind of authentication does REST API require?   Nutanix support multiple authentication options. Want to know about them and how to configure and use them in your scripts? Give the following KB a readKB-2257 Want to know more about Nutanix REST API and different dev tools we provide?

Metro Availability (Standby Site Maintenance steps)

Hello, I will need to power off a "Metro Standby Site", which has VMs running on it. I would like to manually migrate those VMs to the primary (active) site and Shut down / Power Off the nodes in the Standby site approx. 24-36 hours. All VMs need to be running on the active side and no VMs are to be restarted (RTO + RPO =0). The steps I propose to take to achieve the goal are as follows: I have included as much environment info as possible. Any insight or corrections to this process are welcome.

Fibre Channel connectivity to old SAN

Can you use a FC card in one node of a Nutanix cluster to do a storage Vmotion / migration to the New esxi Hosts in the cluster ? FC card will present the current VMFS partition to the new esxi host running in the cluster .Then storage vmotion the vm's across to the new storage( NFS partition in the nutanix cluster ) Is this possible ? Prefered option as NFS would only be on a 1 gig network and we need to do this quickly Any input will be appreciated ?
