Deployment Success

We have already mentioned some helpful resources relevant to SNMP configuration. This time we will take a look at examples, logs location and connectivity testing. Important:Nutanix appliances support only SNMP v2c and v3 (support for v2c in AOS 5.5 and higher). Starting from AOS version 4.1, auth-type MD5 is no longer supported. With SNMP v2c Nutanix support SNMP TRAP instead of SNMP GETFollow trough to KB-1333 Configuring and Troubleshooting SNMP monitoring for commands and examples.The article also reference two more KB articles as well as SNMP related PowerShell commands:KB-2448 How to import MIB in zenossKB-2028 Integrating Nutanix with Solarwinds

I have AHV nodes which have been disconnected on network, I am looking for a method to delete the data on each node through console locally. I have found a command but not sure if this will remove disk or wipe the data? Can someone please guide?Command: ncli> disk delete id="id" [force="force" ]running AOS 5.15.3

Hi! I’ve been getting some reports of users unable to use the numpad part of their 10-key keyboard in Frame… seems to work outside of Frame just fine, and no, numlock isn’t on :)  I’ve seen it, though I haven’t been able to reproduce it myself, or isolate a trigger for when it happens to people. Just curious if anyone else has come across something like this? 

Hello Team,Please help me on the below issue. in our cluster one node is not up and runnig is’s below error for the same.

Trying to upgrade to a specific version by uploading the metadata and binary of 5.17.1.3. This will make the cluster the same as all the others managed by PC.Currently, the version is 5.15.5.1 LTS.When I attempt to upload, I get this response:Software is not compatible with the current installed AOS version This makes no sense to me in that I don’t care that it isn’t compatible. I’m replacing it with this other version. Is this saying that I can’t go from 5.15.5.1 LTS and that I need to upgrade to a 5.16 before I can upgrade to 5.17? Would 5.16 be compatible?I tried finding the answer in the KB, but couldn’t find it (yet).

WE are running on AOS version 5.1.1.3 and planning to upgrade it. When I checked in Upgrade path, the maximum version I can upgrade to is 5.6.2 I need to know, if I want to upgrade to the latest version which is 5.10.0.1, do I have to follow the path like 5.1.1.3 >> 5.6.2 >> 5.9.2 >> 5.10.0.1 , basically a 3 step procedure OR is it that I can upgrade to 5.6.2 only. Please share your views.

Self Service restore (SSR) lets you open and copy a previous version of a file. For SMB, you can use SSR to restore files. Enable or disable SSR through the Prism Web Console SSR for SMB does not restore streams or attributes in directories. Files does not support SSR at the root of distributed shares or exportsFiles take snapshots of the stored cluster data at the share/export level. Self-Service Restore (SSR) exposes these snapshots to the share or export. SSR lets you restore a file from any of the previous snapshots without an administrator. SSR is disabled by default, but you can enable it during or after share or export creation. By default, Files creates a snapshot every hour and retains the most recent 24 snapshots. By default, Files deletes the oldest SSR snapshot after exceeding the retention count for the snapshot type. The snapshot retention count corresponds to the retention period. SSR has the following retention periods: 24 hours of hourly snapshots. 7 days for daily s

I had a LCM failure while upgrading firmware on a node. The node entered maintenance mode and I was never able to get it out. I have subsequently removed the node from the cluster so that I can finish the upgrade process. I have successfully completed the firmware upgrade on the other nodes.Now I am trying to upgrade AHV. LCM is failing prechecks with the message Operation failed: Failed to find node <uuid>The <uuid> is the one of the node that is no longer in the cluster. Some how I need to get past this so I can complete the AHV upgrade. I currently have two nodes at the most recent version and one at an old version. Is there someway to bypass the precheck or to modify the LCM data about the removed node so I can press on?

Hi everyone,When create Volume Group, I’ll select the allowed source VMs to access my VG either internal VM or external client, the question is in which cases I need to configure Filesystem Whitelists? Thanks in advance.  

Volumes acts as one or more targets for client Windows or Linux operating systems running on a bare metal server or as guest VMs using iSCSI initiators. Do not use Volumes to create an iSCSI datastore to Hyper-V or ESXi hosts. This configuration is not supported.The iSCSI data services IP acts as an iSCSI target discovery portal and initial connection point. The client only needs this single IP address to help load balance storage requests and provide path optimization in the cluster, preventing bottlenecks.Enable Nutanix Volume Get the client IP address that you will add to a volume group client whitelist. Create an iSCSI data services IP address for the Nutanix cluster. This address cannot be the same as the cluster virtual IP address. Provision storage on the Nutanix cluster by creating a volume group consisting of one or more vDisks. Perform an iSCSI target discovery of the Nutanix cluster from the clients. [Optional] Configure CHAP or Mutual CHAP authentication on the init

The last couple days I have received an error email indicating that snapshot replication to AWS was skipped because a newer snapshot is available.

Hello, I want to know each usage rate of hosts recommended by Nutanix.(For example, do not exceed 90% of the host's memory.)→ CPU, Memory, Disk Usage rateThis site is an ESXi environment.Is Nutnaix officially documented? Thank you.

Hello Community!! I'd like to discuss an ambiguous issue.There is an 3-nodes Hybrid Storage AHV cluster set to RF2. In this case, each node has 70% storage usage. Each node’s storage capacity is same.Of course, it's 70 percent overall.The data resiliency status is critical.That cluster has enough CPU and memory. The problem comes up from here.If one node goes down, will data rebuild occur?If data rebuilding occurs, the total cluster capacity will be over 95%.That would cause problems with the cluster's IO. Is there anyone who can clearly tell me how the cluster works in the event of a failure in that situation.

AHV host supports load balancing of vDisks in a volume group for Guest VMs. Load Balancing of vDisks in a volume group enables IO-intensive VMs to use the storage capabilities of multiple CVMs If you enable load balancing on a volume group, the guest VM communicates directly with each CVM hosting a vDisk. Each vDisk is served by a single CVM. Therefore, to use the storage capabilities of multiple CVMs, create more than one vDisk for a file System and use the OS-level striped volumes to spread the workload. This configuration improves and prevents storage bottlenecks. vDisk load balancing is disabled by default for volume groups that are directly attached to the VMs. You can attach a maximum of 10 load balanced volume groups per guest VM. For Linux VMs, ensure that the SCSI device timeout is 60 seconds.  Procedure: SSH into the CVM as a nutanix user Do one of the following Enable vDisk load balancing if you are creating a volume group acli vg.create vg_name load_balance_vm_attachm

Hello everyone, After some research i saw that there is no opportunities to collect Total Snapshot Usage (Exclusive Usage) per Protection Domain through the API (i’m on 5.15.3 AOS).As i have lot of VMs per PD, how can i collect this info through Nutanix Cmdlets and obtain this one per PD ?  Thanks.

I migrated 2 linux servers from Xen Citrix successfully. In the image configuration, can I delete the disk images or if I do that the VM will no longer function.

Hi I have a question in the Nutanix enviroment.I need to change control for the ssh to CVM so that just some IPs can access to avoid some intrusion access.I checked the <Nutanix security Guide> and there are some descriptopm in TCP Wrapper Integration, But after I changed the file of /etc/hosts.allow to include just the allowed IPs and CVM management subnet. But It will be changed to default after the cluster security config schedule(by default daily.) Is it possible to change the sshd allow list to achieved this goal? there are security requreiments for the enviroment. thanks.

Now I am studying at Nutanix University. I sometimes see “hot spots” like “eliminate any hot spots” what is exactly means “hot spots”? is it performance of the node or storage degraded? 

Hi,Looking to automate some reports using the Rest API. So far I can successfully pull out CPU, RAM and Physical & Logical storage cluster wide and snapshot details but am unable to calculate the values as shown on the capacity runway when viewing a cluster in PC.. specifically the storage usage figure for ‘snapshots’ and ‘system.Anyone know how these are calculated?Thanks

Hi,Can anyone tell if there is an endpoint in v2 to get stats for VMs? I don’t see it under the VM category. Thanks!

I want to gather data for the following stats metrics using the REST API v2. I understand that I need to put the metrics ID as part of the parameters, is that correct?In addition, can anyone tell me the ID for the following stats metrics?Disk Usage (%) GPU Framebuffer Usage GPU Usage GPU video decoder Usage GPU video encoder usage Memory Usage (%) Network Rx Bytes Network Tx BytesThanks!

I want to use the stats endpoints in the API v2 but the metrics are not documented, how can I get the list of metrics available for each stat endpoint?

Petter Glenstrup shows you what you can do with X-Ray, the performance benchmarking and scenario based testing tool from Nutanix.
