VxRail: Node Add Error on "Configuring ESXi NTP Settings"

When adding a new VxRail node using the VxRM Plugin, the step "Configuring ESXi NTP settings…" fails.

This can occur even when NTP is populated in ntp.conf on vCenter, VxRail Manager, and ESXi nodes. During the node addition, the setting that is used is present on the VxRail Manager Rest API. This parameter is set during the VxRail Manager deployment.

To resolve this issue:

• Start an SSH session on VxRail Manager using mystic user.
• Change privileges using su - and root password.
• Check the current NTP setting on the Rest API using the following command:

curl --unix-socket /var/lib/vxrail/nginx/socket/nginx.sock http://127.0.0.1/rest/vxm/internal/configservice/v1/configuration/keys/system_ntp

• If the value on the last command is empty or invalid, change it using the next command, replacing <NTP_SERVER> field with NTP IP address or FQDN:

curl -X PUT -H "Content-Type: application/json" -d '{"value":"<NTP_SERVER>"}' --unix-socket /var/lib/vxrail/nginx/socket/nginx.sock http://127.0.0.1/rest/vxm/internal/configservice/v1/configuration/keys/system_ntp

• Click "Retry" on vCenter to proceed with node addition. If the NTP server is valid, it should not fail.
