To provide access to cluster storage, Nutanix Volumes utilizes an iSCSI data services IP address to clients for target discovery. This iSCSI data services IP address acts as an iSCSI target discovery portal and initial connection point. Nutanix does not recommend configuring iSCSI client sessions to connect directly to Controller VM IP addresses. 

:exclamation: Changing Data Services IP address requires downtime and planned maintenance for affected services and applications. 

Prior to changing the Data Services IP address, check if any of the features below are enabled on the cluster, such as Calm, Leap or Xi Leap, Karbon, Objects or Files. If none of the features is enabled, proceed with changing the Data Services IP Address as per the Prism Web Console Guide: iSCSI Data Services IP Address Impact.

Karbon and Objects. If Karbon and/or Objects Services are enabled do NOT change the Data Services IP address. Reach out to Nutanix Support for assistance.

Nutanix Files. If Data Services IP is reachable and functional (valid) Files will continue working and no impact is to be expected.

If any of the other features are enabled, proceed with changing the Data Services IP Address by following Prism Web Console Guide: Modifying Cluster Details.

After changing the Data Services IP setting, follow additional steps listed in KB-8216 Changing Data Services IP Address with the respect to features enabled (Volumes, Calm, Files, Leap, Xi Leap, Karbon and Objects)
