How to change the hostname of the Delphix engine

Changing the hostname

Perform the following steps to change the hostname of a Delphix engine.

Currently, it is only possible to change the hostname via the Command Line Interface (CLI).

1. Stop all running VDBs by clicking the Stop button on the VDB card.

2. Disable all dSources.

3. Log into the Delphix CLI using your sysadmin username and password. If you are using the same interface that you connected to the CLI on, it will interrupt the connection. Therefore, it is recommended to log in to the CLI on the console.

   CODE

   ssh sysadmin@yourdelphixengine

4. Run the following commands.

   CODE

   dlpx01> network
   dlpx01 network> setup
   dlpx01 network setup> ls
   Properties
       defaultRoute: 192.168.0.1
       dhcp: false
       dnsDomain: plb.internal
       dnsServers: 192.168.0.111,198.142.152.164,198.142.152.165
       hostname: dlpx01
       primaryAddress: 192.168.0.109/24
   
   Operations
   update
   dlpx01 network setup> update
   dlpx01 network setup update *> set hostname=newhostname
   dlpx01 network setup update *> commit

5. If DHCP is being used, the Delphix Engine will expect the Hostname to be provided by the DHCP server. As such, there will be no property 'hostname' to update. This process requires changing the IP addressing configuration from DHCP to static address configuration. To proceed you will need to take the following action (making sure that there is no conflict between your DHCP server and the changes you are implementing).

   CODE

   dlpx01 network setup> update
   dlpx01 network setup update *> set dhcp=false
   dlpx01 network setup update *> set hostname=newhostname
   dlpx01 network setup update *> commit
   newhostname network setup> update
   newhostname network setup update *> set dhcp=true
   newhostname network setup update *> commit
   newhostname network setup> ls
   Properties
       defaultRoute: 192.168.0.1
       dhcp: true
       dnsDomain: plb.internal
       dnsServers: 192.168.0.111,198.142.152.164,198.142.152.165
       hostname: newhostname
       primaryAddress: 192.168.0.109/24

6. Re-enable the VDBs and dSources running from the engine.
