Prism central server is not reachable

Do you mean Prism element (i.e. the nodes themselves) or Prism Central (a separate deployment)? What output do you get from the cluster status command? It looks like you have two CVMs down. Cheers,Steve

Static IP Information not Displaying after Moving to Nutanix

If you go to your case in the portal then you can click ‘Escalate’ if you’re not getting a response, or just give them a call and quote your case number and whoever answers the phone will be able to help you.

Static IP Information not Displaying after Moving to Nutanix

I’m not sure how you have fixed IPs but DHCP is still ticked Does ipconfig /all look correct? Did you get a response to your Nutanix ticket?

Nutanix - Server is not reachable

As you’ve tried other browsers etc this doesn’t apply, but if the server producing the Prism web pages has changed then you need to refresh the page to get it to check the SSL cert again. If the CVM is overloaded and can’t produce the Prism interface you can see this too. Are you able to SSH to the CVM?

Nutanix NTP Sync with Microsoft Windows NTP Services?

I’ve noticed the same problem but we’ve moved our NTP sources to be different devices now (core network switches) and that’s our new standard and Nutanix no longer complains.I wonder though, have you tried playing with these settings?---/LocalClockDispersion:<seconds>: Configures the accuracy of the internal clock that W32Time will assume when it can't acquire time from its configured sources./reliable:(YES|NO): Set whether this computer is a reliable time source. This setting is only meaningful on domain controllers.YES: This computer is a reliable time service. NO: This computer is not a reliable time service.From: Windows Time service tools and settings | Microsoft Docs---To make Windows ‘pretend’ its reliable? Cheers,Steve

Mount External Datastores to VMware on Nutanix

I can’t imagine it being recommended but you can technically mount external sources in VMWare or in the VM itself but you won’t be getting any of the Nutanix storage fabric advantages. Note that you can get ‘storage only’ nodes to boost your Nutanix capacity.I used to run a Windows file server VM with local storage on Nutanix for performance to profiles and home drives, but iSCSI volume mapped out to a cheap NAS box for the main document share.

Static IP Information not Displaying after Moving to Nutanix

So the VMs are now DHCP? If you now have different vNICs (Nutanix vs Intel vs vmxnet3 etc) then maybe the static IP on the old disabled/hidden adapter and you need to reapply the setting to the new adapter?

CPU scale up

I’ve just done this on my home CE cluster - just evacuate the node, shut down in the normal manner, swap out the CPU and bring it all back up again. Any VMs will need shutdown/restart on the new CPU to ‘see’ it though.Looks like EVC equivalent on AHV is done automatically Living Migration Between Old and New Processors | Nutanix Community - but I didn’t need to worry as I was swapping out the same generation, just adding cores/GHz.But anyway, if this is a production cluster under support/maintenance I don’t think you should mess around with CPU upgrades yourself as @bcaballero says!

asked in Installation & Configuration

Can I view data reduction ratio per vdisk or per VM instead of the whole Storage Container?

I’ve been doing a bit of digging on this and found you can get per vdisk info but it’s not very useful.You need the vdisk ID which I found doing: vdisk_config_printer | grep -B 15 VMDKNAME | grep vdisk_idThen stats on that actual vdisk is found using:curator_cli get_vdisk_usage lookup_vdisk_ids=xxx Overall container stats are better using this: curator_cli display_data_reduction_report I found also the stats can take a day to update!

Disk drive performance

Forgot to update this post - after a couple of days this problem went away. Seems a common thing on some Samsung SSDs that they’re slow for a while after a format.

Oh I had to do it again but adding the other hosts in as i had a similar error in genesis logs, then I restarted genesis and the lcm leader moved to another host and now the LCM prechecks have completed and inventory is running!

LCM Framework Stuck Updating

I just had a play and I fixed it! It’s now doing a framework update. I *think* the command that did it was zkcli write /appliance/logical/lcm/mercury_config/f58690da-9d18-400c-8a6a-f7d3a4e09b28as that id now shows when I do a list. I did so many different commands I’m not 100% sure it is that one though :)Cheers,Steve

No I’m already on the latest :( I’ve today got to a different stage by leaving it overnight. When I go to the LCM page it just says “Waiting for LCM Framework to start...” edit oh leaving it for a few minutes it’s back to “LCM Framework Update in Progress, please check back when the update process is completed.” I notice in genesis log this repeats over and over: 2021-03-10 10:23:17,117Z INFO ergon_utils.py:825 No LCM operation running2021-03-10 10:23:17,118Z INFO ergon_utils.py:1595 Cannot find root task uuid2021-03-10 10:23:17,121Z INFO zeus_utils.py:413 Zk node /appliance/logical/lcm/mercury_config/f58690da-9d18-400c-8a6a-f7d3a4e09b28 doesn't exist2021-03-10 10:23:17,121Z INFO framework.py:2196 Mercury config is in progress.

There’s nothing there that helps me in the state it’s in unfortunately. These don’t exist: ~/data/logs/lcm_ops.out or ~/data/logs/lcm_wget.logNo stuck tasks in ergon.outNothing interesting in genesis.out….lcm/lcm path doesn’t exist so no issue there.I think I need to clear the upgrade status that’s set somewhere for NCC to report this against most of its checks:Detailed information for ahv_version_check:Node 192.168.250.237: INFO: Cluster/node reports it is currently undergoing maintenance/upgrade. This health check plugin is disabled during this workflow to avoid inaccurate results or alerts but will run again when the workflow completes. See KB4999 for more details.

I just tried moving the lcm_leader to another node (no idea how to do this so I just rebooted the CVM the lcm_leader was on!) and it now just hangs on “Loading...” when going to the LCM page in Prism.
