Nutanix Cluster Timezone configuration

“VMTurbo"

One question i receive from time to time during Nutanix discussions, Nutanix implementations and via twitter is how to configure the correct timezone for the Nutanix components e.g. Nutanix Cluster and Nutanix Controller Virtual Machines (CVMs).

After an installation you’ll have the PST (America/Los_Angeles) timezone configured and unless you are in that region it might be a good idea to change the timezone. This will make it easier during log analysis for mentioning one thing.
List the existing timezone configuration using the ncli command on any CVM using.

ncli cluster get-params

For my home lab the output was the following:

Cluster ID: 00019827-872a-ab79-0000-000000004a1d::15403
Cluster Uuid: 00019827-872a-ab79-0000-000000004a1d
Cluster Name: ahv01
Cluster Version: 4.5.0.2
External IP Address : 10.ABC.ZYX.135
Node Count : 3
Block Count : 1
Support Verbosity Level: BASIC_COREDUMP
Lock Down Status : Disabled
Shadow Clones Status : Enabled
Password Remote Login: Enabled
Timezone : America/Los_Angeles
Has Self Encrypting Disk  : no

Timezone can also be verified per CVM by running the date command and the output will be e.g:

Tue Nov 24 23:19:28 PST 2015

Since i’m based in Sweden it make sense to set Stockholm as the default timezone and pretty much all configuration needed can be set, verified and changed using the ncli command. To change timezone you can use the following command:

ncli cluster set-timezone timezone=Europe/Stockholm

Verify the change by running get-params command again:

ncli cluster get-params

Now the output will be

Cluster ID: 00019827-872a-ab79-0000-000000004a1d::15403
Cluster Uuid: 00019827-872a-ab79-0000-000000004a1d
Cluster Name: ahv01
Cluster Version: 4.5.0.2
External IP Address : 10.ABC.ZYX.135
Node Count : 3
Block Count : 1
Support Verbosity Level: BASIC_COREDUMP
Lock Down Status : Disabled
Shadow Clones Status : Enabled
Password Remote Login: Enabled
Timezone : Europe/Stockholm
Has Self Encrypting Disk  : no

The timezone will be configured per CVM as well so when running date  command again you’ll have the following output:

Wed Nov 25 09:32:53 CET 2015

To list the available timezones you can run the below command which is the same as when you set the timezone but you give a non existing timezone as the value

ncli cluster set-timezone timezone=test

Output for this command will be:

Error: Value ‘test’ provided for authentication type is invalid.

    Hi,
    yes it does. What version are you running of AOS and can you send me the output from “ncli cluster|grep -i time” command?

    thanks
