5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
In scripts we use for some ESXi hypervisor configurations we utilize “allssh”. The problem I’m running in to, though, is I must run each allssh command individually rather than using a script to run multiple allssh commands. The first line will kick off and before it has a chance to complete the second will kick off. For example, here’s where we configure DNS on the hypervisor through a CVM: allssh ssh root@192.168.5.1 esxcli network ip dns server add --server=10.1.1.1 allssh ssh root@192.168.5.1 esxcli network ip dns server remove --server=8.8.8.8 allssh ssh root@192.168.5.1 esxcli network ip dns server add --server=10.1.1.2 The first will kick off then the second goes prior to the first completing. The script then gets confused and stops while still connected to one of the ESXi hosts. Does anyone know of a way to initiate subsequent allssh commands only after the prior one running has completed? Although not very clean, should I put a sleep command in between each?
Would anyone have X-Ray Four Corners Microbenchmark results for the following scenarios:2-node Nutanix cluster, 1 GB uplinks 2-node Nutanix cluster, 10 GB uplinks 3-node Nutanix cluster, 1 GB uplinks 3-node Nutanix cluster, 10 GB uplinksI'm testing some scenarios against Cisco Hyperflex and HPE SimpliVity (which I currently have environments to test against), but don't have access to any Nutanix hardware.BTW...X-Ray is a GREAT product!
Is there a KB or documentation providing the JSON format and any additional things that may be coded in? For example, in going through the install.nutanix.com portal to generate the JSON file it doesn't ask for NTP server of the hypervisor. In looking at the file, though, there's this line: "hypervisor_nameserver": "8.8.8.8", I'd like to have our Nutanix deployments in code as much as possible (right now we're looking to various scripts for vSphere configurations). Being able to configure as much as possible up front and possibly make this a template for future deployments.
I know this can be done with the NX hardware using the IPMITOOL utility pre-installed, but we’re starting to use HPE hardware and I wondered if anyone knew how to change the iLo administrator login password via cmdlet? We’ve scripted this for NX line and looking to do the same with HPE’s as a part of our deployment scripting.
I have the commands for setting up a user and access level, but I’m not having any luck when configuring the SNMPv3 portion. I need to setup the following and would like to use IPMITOOL rather than manually logging into the IPMI: Has anyone been able to do this?
