I would like to run a command from a host to gather the info just allssh does on cvms. I would like to avoid login into all the host and run a quick check from any of them. is there any easy way to do that?I read about hostssh command but my bash is not able to found it.

Can someone explain the difference between the two ?? and what are the pros and cons of them

Hi i need to download AOS 5.10.0.1 LTS

it used to take considerable effort to deploy nutanix in qemu/kvm lab, previously i had to modify install script to bypass bs hdd/ssd performance tests, etcrecently i had to test something and needed to deploy ahv,  i noticed installation iso and i thought, hey, i don’t think it was there before, probably nutanix is going in the right direction by simplifying things and now i get “an error occurred while trying to  illuminate the chassis led” and index out of range related to boot disk with that iso, loli guess i will have to dig into these install scripts againplease invest time in testing virtual deployments, and please follow KISS principleoff-topic: you have a category here in forums called “Deployment Success”, please create “Deployment Failure”, so that i and many others could properly place these threads

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

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).

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

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.  

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.

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.

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?
