Deployment Success

Hello I don't know if this will be useful for anyone but I came up with a few command lines to change the default passwords for the CVM and IPMI users and create a new user to mimic the dell DRAC's user #change IPMI passwordfor i in `hostips`; do ssh root@$i 'for id in `/ipmitool user list |grep 'ADMIN '|cut -d" " -f1`;do echo $id;/ipmitool user set password $id ;done' ; donefor i in `ncli host list | grep -E 'ID ' | cut -d":" -f4`; do ncli host edit id=$i ipmi-password=; done #create root user on all nodes ipmi to keep consitant with Dell Dracfor i in `hostips`; do ssh root@$i '/ipmitool user set name 3 root;/ipmitool user set password 3 ; /ipmitool user priv 3 4;/ipmitool channel setaccess 1 3 privilege=4;/ipmitool user enable 3' ; done # change esxi passwordfor i in `hostips`;do echo "--$i--";ssh root@$i 'echo -e "" | passwd';done #change cvm passwordfor i in `svmips`;do echo "--$i--";ssh nutanix@$i 'echo -e "" | sudo passwd nutanix';done

Hi, I am doing some tests with creating and deleting large files in a sles12 installation on our AHV environment. I use an ext4 filesystem and have enabled the trim/discard feature for the filesystem and lvm. But when i delete a large file with random data (5g size) the storage backend of the cluster does not see that the former used storage is now not longer used. I tried fstrim to initiate the cleanup but that doesn´t work. If I write zeros to the file/partition/filesystem then the backend gets backs the storage. Is trim/discard supported to tell the storage backend that filesystem space is no longer needed or does anybody has experience with such a setup ? Thank you for your help. Regards Hans

Hi there, I don't seem to be able to see any way of letting SSP users take Snapshots of VMs. Is this something that is possible? Cheers, Tim

Hi all ! My client have encountered a strange behaviour on some of its Nutanix-Dell Blocks and i'd like to share the resolution on this. Thanks to Nutanix / Dell support team for their 'patience' with IT team on this false-positive critical alert resolution. context : Multiple critical alert Seen on PRISM : FAN SPEED LOW for a whole cluster (this mean all FANS on ALL blocks). No alerts detected on IPMI / IDRAC and VIclient (directly on ESXi for HW messaging). HW: DELL XC 630-10 SW : NOS 4.6.4 HV : ESX 6.0 u2 Resolution : This is a false positive message which occurs when NOS cannot correctly interpret IPMI messaging due to a miconfig on a /etc/nutanix/hardware_config.json. the sensor of type "fans : rpm" has a misconfig on its adress. GOOD adress is "ipmi_sensor:FAN" BAD adress is "ipmi_sensor:FAN RPM" resolution will be to modify this descriptor for each FAN (14 on a XC630-10 model) on each host. If you encounter this kind of issue, please contact NUTANIX / DELL suppor

Hi All, I upgraded our single node cluster last night, and it went pretty smooth. However, today I am noticing placeholder text (i.e. "vm_critical_alerts" instead of "Critical Alerts" and many, many fields coming back simply as undefined. Is this a known issue or did something go awry during upgrade? SSP is also not working, but I'm active in another thread for that. Thanks! Tim

How do i disable the features in Prism Central so i dont get a License Violation? I dont have a license for Prism Central - so just want it with the starter license..

I am trying to find a download link for AOS 4.7.3.1. It looks like only 4.7.3.3 is available. Where would I find a link to download older AOS versions?

Recently it appears that our "Automatic Downloads" function is not working anymore. I referenced following link to force immediate download for updates: http://aakashjacob.blogspot.com/2015/02/nutanix-techtip-2-enable-automatic_6.html The results of the auto download log output are below: This is output from a Nutanix CE cluster but it is the same error I see on one of our other full blown Nutanix clusters. What do the errors mean and what could be causing them? AU used to work before the holidays and there was a Palo Alto FW update done during the holidays. I have worked with the person responsible for the PA and he has tried everthing to allow traffic out from the IPs of the CVM(s) and still no luck. Any input would be appreciated...

Hello, I have a query here, we have deployed nutanix 4node in cluster with Windows 2012 R2 STD Hyper-v as hypervisor and provisioning of vms are also done. Now due to the increase in vm requirments, we need windows 2012 R2 STD hyper-v to be converted to Datacenter Edition without affecting the existing environment. I know converting Windows 2012 R2 STD to Windows 2012 R2 DC is possible in windows, however since ti is with nutanix i would like to know the possiblity and what is the way forward. If i convert via windows 2012 R2 will that impact the nutanix CVM in communicating and managing.

Hi all We have a small DEV 3 node lab to test features before moving forward, one feature in 5.0 we are looking forward too is the Self service portal, after upgrading to 5.0 I have selected the SSP which then asks for an ldap user, although this user authenticates correctly from Prism / Authentication / test When entering the same user in the cresentials for SSP I get the following error; Server with access directory url:ldaps://****** is down Has anyone seen this? is ldaps supported? as mentioned it works for Prism authentication This clutser is not under support, we are looking at a dev support option for this currently but we do have many other clusters Thanks Jason

Hi All, Thanks for caring..

Hi , I am facing issue with foundation VM based process.Installation failed after phoenix got installed with fataling errorAs well as throwing error as foundation failed configuring IPMI ip's [i did manually configured iDrac IP's before starting foundation ]

Hi, I upgraded BMC Firmware from 03.24 to -> 03.40 via IPMI UI today since that i can check the version of BMC on IPMI UI page that its 03.40 upgraded among 3nodes which i upgraded but its not the same on PRISM even its accomplished. i can only see that BMC Firmware 03.40 isnt upgraded on PRISM among 3nodes i use AOS 4.7.3.2 with AHV Nutanix 20160601.44 additionally, i have this fail message via conducting ncc health check funtion All 4nodes have intel CPU in them.

Hi, Is it possible to see VLAN base traffic in Nutanix with AHV in GUI or using CLI?

How to configure PRISM / AHV for syslog?

We are using Apache Cloudstack 4.8.0 with Vmware 5.5 to to provide IAAS services . We want to use Nutanix as underlying infrastructure Is this implementation supported ? Is there any recommendations, best practices for deployment or a reference architecture? We also plan to have HA for a class of our vm whereas others should not be replicated. What kind of mapping between Cloudstack and Vmware organisation units, and Nutnaix Protections domains strategies should we have to achieve this goal. If none of the above is supported is Apache Cloudstack in Nutanix roadmap on Vmware or AHV ? Thank you in advance

Dears We are configuring an iSCSI target , and we have security between ipnetworks, where CVM and the host vm are in seperate network. please advise ,which all are the ports needs to be opned.

Hi all, I have already posted this problem in other forum section but maybe it should not be there so I repost it here so that I could get an appropriate and fast answer To summarize the problem, I am in the same situation in which I cannot enable the deduplication on HDD and I have also tried running the commands below and the result seems a little bit inadequate because I have configured the CVM RAM up to 32GB nutanix@NTNX-13SM31320001-B-CVM:10.9.120.115:~$ allssh 'grep "for on-disk deduplication feature" ~/data/logs/stargate*'Executing grep "for on-disk deduplication feature" ~/data/logs/stargate* on the cluster================== 10.9.120.114 =================FIPS mode initializedNutanix Controller VM================== 10.9.120.115 =================FIPS mode initializedNutanix Controller VM================== 10.9.120.116 =================FIPS mode initializedNutanix Controller VM/home/nutan

Hi Gents, I am facing an issue with upgrading ESXi 6.0 update 1 to Esxi 6.0 Update 2. Please find the details below. NOS: 4.7.3 Hypervisor: ESXi update 1, looking to update to ESXi 6.0 update 2. H/W: Lenovo HX5510 Issue: I downloaded the respective binary from Lenovos website which shows as compatible for HX5510. MD5SUM looks good after uploading the ESXi binary but i see "(not qualified)" after the iso fille name on the upgrade screen. Also there is a warning in red on top of the upgrade page that says Version ID of the software release, , does not exist. Is it because Nutanix is yet to pass quality for this version or is it not supported at all ? Also is there any link to view a interoperatibility matrix for nutanix nos versions against different hypervisor version support ? Cheers,

Hi last week we installed the first Nutanix cluster in Venezuela with 3 nodes, it was founded and as a best practice, the vSwitch br0 was "splited"into two vswitches by creating the br1 then the 10 GBE interfaces (eth2 and eth3) were assigned to the br0 and the 1 GBE interfaces (eth0 and eth1) were assigned to the br1, the administrator of the cluster decided to switch that assignment, i.e. to assign the 1 GBE interfaces to the br0 and the 10 GBE interfaces to the br1 by executing on the CVM's command line the command. allssh manage_ovs --bridge_name br0 --bond_name bond0 --interface 1g update_uplinks after the third node response to the command, the connection to the ssh sesion to the CVM was lost and now can't access the CVMs to revert the command neither ssh connection nor PRISM. In the nodes the 1 GBE interfaces leds are orange and red, only have access to the console by connecting a monitor and a keyboard to the physical nodes, my question is, does exist a way to revert the p

Hello! I am looking to delegate the ability to shut down and start back up our Nutanix cluster to our team without providing the root nutanix passwords. Is it necessary to perform a cluster stop/start via SSH into a CVM, or can we shut down everything without stopping and starting the cluster? Thanks! Ryan

Folks,Has anyone use or deploy Nutanix on Cisco UCS platform? Which hardware spec? Where to get Nutanix license for the nodes?

Dear Sirs Please advise , we are installing Dell XC 6320, where all network card are 10G (4x10G) and we used 2x10g for all the traffic (which is our test and development cluster) , we have total 8 nodes in the cluster. Someone is now telling us that the best practice is to use another 10G netowkr card for CVM traffic , as the CVM traffic in Nutanix is very heavy,which should not mix with production network card, Is that true , i have gone thru the previous posts and sure that 2x10G is fine for all Nutanix traffic, for my knoledge is the Nutanix CVM traffice is that heavy between nodes ? your reply is much appreciated.

Right now we about to push ESXi 5.5 u3b so we can move on up to AOS 4.7.3.2. Since Nutanix doesn't support pushing out patches, we planned to do that with VUM which is fine. At least saving time from having to bring down each node manually for upgrading to u3b. On top of patching, we're also installing NFS VAAI VIB. In our lab, we do it via command line, but has anyone found a zip, or package that VUM can support pushing out that way we can just package our baseline with updates and the VIB file? We can't find anywhere that has a zip file or anything we can leverage thus far. Since we have two data centers a good number of nodes in the cluster at each, We'd love to save time if at all possible, so any advice is greatly appreciated. Thanks!
