Nutanix Hyper HCI developed it’s own KVM based hypervisor known as Acropolis Hypervisor (AHV) which enterprise cloud ready platform to build Hyper HCI infrastructure to run any type of applications in production.
To change the Nutanix Acrpolis Hypervisor AHV host name is very important to make entry in Domain Name Server (DNS) for name resolution.
Lets proceed to do hands on changing Nutanix AHV host name will have to run simple command and do edit two scripts to change the Nutanix AHV hostname.
Changing Nutanix AHV Host name
Step 1 : SSH to Nutanix AHV host using port number 22 through putty client
Download : Putty client software
Step 2 : check current Nutanix AHV host name first
ahv@root# hostname
Step 3 : Edit the /etc/sysconfig/network file and set the parameter
Result would be like this
HOSTNAME=NX-Block-Number-AHV
Changing Nutanix AHV hostname in network file as below
ahv@root# vi /etc/sysconfig/network
HOSTANME=New-AHV-Hostname
Save the file to enter :wq!
Step 4 : Edit the /etc/hostname file
Result would be like this NX-Block-Number-Ahv
Changing Nutanix AHV hostname in hostname file as below
ahv@root# vi /etc/hostname
Note : Remove the Old-AHV-Hostname entry then enter New-AHV-Hostname New-AHV-Hostname
Save the file to enter :wq!
Step 5 : Change current Nutanix AHV host display name
ahv@root# hostname New-AHV-Hostname
Above steps will successfully change the Nutanix AHV hostname
but New-AHV-hostname will not reflect in Nutanix Prism Web-console untill you reboot the Nutanixh AHV host and its hosting Nutanix CVM.
Run Acropolis command to avoid AHV host reboot
To avoid AHV host reboot and reflect New-AHV-Hostname in Nutanix Prism or Prism Central need to run single extra command
Step 1 : SSH to Nutanix CVM of that particular AHV host you were changing the AHV hostname
Run following command
CVM$genessis stop acropolis; cluster start
Step 2 : Log out from SSH of Nutanix CVM and AHV host
Step 3 : Now log on to Nutanix AHV host with SSH and Nutanix Prism web console to see New-AHV-Hostname.
