Prism Central (CE) - httpd will not start

Hi, I seem to be having a problem deploying Prism Central using the automated deployment. Everything seems to go through fine, the VM is created however the install task always fails. Looking at the Prism Central VM, it seems the httpd service cannot start up, with the error: [code]Redirecting to /bin/systemctl status httpd.service ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2018-10-08 00:59:43 PDT; 1min 34s ago Docs: man:httpd(8) man:apachectl(8) Process: 5495 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Process: 5493 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 5493 (code=exited, status=1/FAILURE) Oct 08 00:59:43 ntnx-192-168-4-59-a-cvm systemd[1]: Starting The Apache HTTP Server...

Using nCLI non-interactively

I would like to download the cluster info file so I can apply licenses to my prism element over CLI. I can do this interactively by opening an SSH command and it asks if I am sure [y/N]. When automating this, how do I go about entering “y”? I usually get around this by using -echo 'y' | ncli license download-cluster-info file-path='/home/nutanix/cluster_name.csf' But its not liking it -nutanix@NTNX-20FM5A210030-A-CVM:10.248.8.62:~$ echo 'y' | ncli license download-cluster-info file-path='/home/nutanix/L02VM1.csf'This operation will start the licensing process. Are you sure you want to proceed (y/N)?: Error: null

AHV and CVM fails after restarting the AHV nodes

Hello People, Facing strange issues on deploying Nutanix 3 node cluster. Everything is completed without any issues deploying Nutanix. After restarted the nodes we are not able to reach AHV Node IPs after logging into ILO manually restarted the network services and then the AHV and CVM are reachable and all the cluster is normal. These happen only I restarted the nodes or shutting down AHV.Before restarting, network interfaces are up only.   From Switch side we have configured access port VLAN tagged 1010.  Here eth4 is connected on switch-1 port 1 and same eth6 is connected on switch-2 port 2  Note : Both switch-1 and switch-2 is stacked  Model : Cisco SG350XG  AOS : 5.20.1.1 LTSHere my config nutanix@NTNX-CVM:101.101.0.13:~$ allssh manage_ovs show_uplinks================== 101.101.0.14 =================Bridge: br0  Bond: br0-up    bond_mode: active-backup    interfaces: eth6 eth4    lacp: off    lacp-fallback: false    lacp_speed: slow================== 101.101.0.15 =================

Prism Central - home partition does not expand to 50Gb

Currently running PrismCentral pc.2021.3.0.2After upgrading to this version, the /home partition is supposed to expand to 50gb from 40gb.  This unfortunately did not happen.I found KB9525, and tried to run this command to manually expand the partition:sudo python /usr/local/nutanix/bootstrap/bin/pc_config_home_partition.py --skip_end_sector_validationThat didn’t succeed in expanding the /home partition (which was sitting at 91% utilisation)In the pc_config_home_partition.log file, I found this error::178 BLKRRPART: Device or resource busysfdisk: The command to re-read the partition table failed.Run partprobe(8), kpartx(8) or reboot your system now, before using mkfsI ran partprobe, didn’t helpkpartx requires parameters, and I wasnt sure what inputs to provide, so I didn’t run thatI did reboot Prism Central, but that didn’t help either, except it did somehow reduce disk utilisation of /home to 76% from 91%.  Still couldn’t expand the disk thoughAnyone faced a similar situation, or have

Alerts Dashboard

Hey folks,I have created an Alerts dashboard for a cluster. The project is meant to be an enhancement to the Analysis page in Prism in terms of data visualization. You get a single page view of the alert stats generated in your cluster.https://github.com/nkunnath/dash-alerts-ntnx Please feel free to try it out and let me know if this has been useful. Any suggestions/improvements/ideas are welcome.  Cheers!

Changing CVM memory size from Prism

Hi everyone,I want change current CVM memory size from 32GB to 40GB (AOS 5.15, NX model)but when I select Configure CVM in the Setting page,there is no option for 40GB from dropbox (only 36GB, 48GB and 64Gb)But when I checked on other Nutanix cluster (AOS 5.20, HX Model)I can choice 40GB from dropbox.So is it behavior change from 5.15 to 5.20? or It depends on Hardware model (NX vs DX)Ref URL: CVM Memory ConfigurationAnd if I want to change CVM memory to 40GB, I must using CLI?

 ‘Resiliency Status’ in Prism Central widget

Prism Central pc.2021.5 added the ‘Resiliency Status’ to the Storage widget which is a cool idea. However all of my PE clusters in this widget show as Unknown with a callout that reads “Details are unavailable in Clusters < 6.0”.Looking at the latest downloads available online I do see a version 6.0 of AOS for the STS release path so I assume that we’ll have a wait a little while longer for us LTS customers.

Minimun recommended snapshot frequency

In case you have to configure a snapshot frequency for a business critical application that can sustain a maximum of 40 min of data loss, is it better to configure the snapshot frequency of the protection domain at 15min or is it better to set a 30min frequency?

Number of vCPUs vs Number of Cores (UVMs, NUMA and CVMs)

Do you still wonder which one to use Number of vCPU or Number of Cores per Socket when configuring a VM? You read something about it and it makes sense and you think you will now remember only to stumble upon the same dilemma sometime later. Shall we clear this once and for all?   vCPU and cores are inherently bound to a NUMA node which, in essence, is as a processor with direct attached memory. Under some (but not all) conditions, accessing memory or devices across NUMA boundaries will result in decreased performance. Hence the goal is to configure a VM with CPU and memory values that remain within the boundaries of a single NUMA node. The exception would be a NUMA-aware application. Another thing to remember is that hot add of the number of cores is not supported on AHV meaning adjustment of number of cores value for a VM requires the VM to be a powered off.   To ensure optimal performance of the VMs in the cluster follow simple rules: Use vCPUs instead of cores to increase the

Prism Central: VM Backup / move to another AHV cluster

Hi folks! Does anybody backup Prism Central VMs in a Protection Domain? I was just thinking about that, since I need to move all VMs from one AHV cluster to another. That's because I need to reinstall the cluster with ESXi for compatibility with some VMs. The only way I found out is to create Protection Domains and replicate the VMs to the new cluster. So does this work with PC VMs also? Regards, Andy

I can’t seem to find the msg be it account or creation. Is there a need for me to add in other modules as well? I am kinda stuck with this step. Any help would be greatly appreciated.

Very long running Prism Central Task

As seen in this attached screenshot, Prism Central appears to have lost track of this “running” task.  Updates of network security rules normally finish very quickly (I think might have clicked an apply button twice after editing a FLOW security policy during on-site FLOW training.)  Is this something only Nutanix Support can clear away?
