OVS Networking - Unable to bridge eth0-4 for other networks - Error

What's my goal? Right. I have 3 networks that cannot talk to each other for "reasons". Mostly because we have a test system that utilizes the same IP addresses (ORACLE Reasons) and we test & demo software in Prod, Demo, & Test networks. I just did a foundation on my system because I did an upgrade and the networking customization I had to do with OVS changed and wouldn't work anymore. Now that I'm working on a new install, I'm having trouble configuring the network and getting issues I didn't have before. I've created and recreated several times using different varieties of below commands and still same outcome. Some commands below are from various tries, but same result. Error when powering on VM with virtual NIC Operation failed: InternalException: kNetworkError: OVS error (10.1.16.103 create_local_port): Error not a valid bridge: br1 Host A - ovs show [root@HOSTA ~]# ovs-vsctl show 48fd5ca1-d898-425e-9b11-484eaceaba94 Bridge "br0" Port "br0

Prism and DVS Iissue

I have encountered an issue while migrating to a dvs, I am running esxi 6.5 on a 3 node cluster. The setup is new so there are no VMs apart from the CVMs and a test VM on the host. The dvs already exists and I am doing one node at a time and as such I added one of the NICs from node A to the dvs. I then did a quick test with the test VM on each port group I have configured to confirm connectivity. I then attempted to migrate the VM Network port group created on vSwitch0 that the CVM on node A was connected to, the migration "worked" but connectivity to the CVM was lost. In addition to losing connectivity to the CVM on node A, I am now unable to access prism from any of the CVMs or cluster IP. The page loads but once I attempt to login nothing happens. I even powered off node A in hopes that I can get to prism but still no luck. All CVMs and the cluster IP are reachable via IP, the esxi hosts for node B and C are also fine and reachable. Not sure where to go from here other than tear do

Is there Foundation release note or support-unsupport list?

Hi all is there any guide for what ESXi version/build-number is support or unsupport about Foundation? Sometimes I need to know what version Foundation can install what version ESXi Or I only use the newest version Foundation to install older version ESXi? Does it always work? I hope there will be some information let me know when I install older ESXi on newer Nutanix using newer Foundation Some Costomers not always use the newest ESXi thanks!

Update Failure

Hi all, today I wanted to upgrade NOS on one of our clusters from 4.1.x to 4.6.3 which worked perfectly fine for another cluster. The first CVM was updated successfully but the next CVM Update failed. (Maybe due to connectivity issues to the host.) upgrade_status says, that the node is upgrading right now, but in fact the CVM is powered off and won't boot. After it displays the following information it reboots fails again and after the second reboot it stays shut down. Is there a simple fix for this or do I have to open a support ticket? EDIT: it seems like the update process tried to shut down this cvm but got a timeout and now the update is somehow stuck. Can I somehow restart the upgrade process or manually update this CVM? Thank you.

Shutting down a CVM

Just implementing a new cluster and I've ran foundation with NOS4.5.1.2 and ESX 6. The ESXi hosts have not yet been connected to vCenter. One of the post image steps is to set the correct time zone for the cluster. It says that each CVM needs to be shutdown in Serial. Is this a simple case of connecting to a each ESXi host and shutting down the CVM, Power it back on, connect to the CVM, via http://cvmip to check that it is up, then move on to the next ESXi host and repeat? Thanks Chris

Remote Site vStore Mapping not accessible

After a failed upgrade that resulted in a failed node, we reinstalled the node and added it as a remote site so we could migrate to it and reinstall the other nodes. When I added the site on the old cluster it works as expected, but on the reinstalled node I cant add any vStore Mappings and are instead greeted with this message "Remote Datastores are either not configured or not accessible." When I run ncli> remote-site list on the reinstalled node I get: Status : unreachable and on the old cluster: Status : relationship established Is there any log output/command that could help me troubleshoot this further?

Keyboard Layout - Prism Console

We are using Nutanix ( AOS 5.5.0.6) with AHV-Hypervisor. Connecting to a VM(W2K12,W2K8, German) via Prim & VNC-Console there is no possibility to change Keyboard-Layout. Our Computers are on Win7 - German with German QWERTZ - Keyboard Layout. No matter which Browser we are using (IE11, Chrome, Firefox) we can not type special characters like \ / . We also tried the American Key for / \ without success. Is there a posibility to fix this Problem? Or is it a Bug ? Looking forward to hear your comments: F.Hil

Oracle + Dual hypervisors in 1 Cluster

Hey Guys, I have a question: Let's say a customer needs to deploy some Oracle databases. As wel all know, licensing is expensive.. In this scenario they have a 11 node cluster. Would it be possible to have 2 nodes run on AHV with oracle whilst the remaining 9 nodes run on ESXI?(They only need 2 nodes hence they don't want to use a third node & create another cluster + They would like to benefit from erase coding.) This would cut the Oracle costs by a huge amount. Or are there any other solutions for this? Thanks in advance! Sebastiaan

Hi, I have a Huawei Switch S7706 (10G) which is used with Cisco LR/ SR SFP+ to connect devices. Wish to know the Nutanix standard DAC Cable C-CBL-5M-SFP+-SFP+ is also compatible ?

trim/discard support

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

INFORMATIONAL : how to correct FAN critical alerts on NUTANIX-DELL configs

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

Place holder text and &quot;undefined&quot; in GUI after upgrade to 5.0

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
