Manage NetApp HCI
NetApp HCI management overview
You can manage credentials for NetApp HCI, user accounts, storage clusters, volumes,
volume access groups, initiators, volume QoS policies and the management node.
Here are the items you can work with:
• Update vCenter and ESXi credentials
• Manage NetApp HCI storage assets
• Work with the management node
• Power your NetApp HCI system off or on

Update vCenter and ESXi credentials
To maintain full functionality of NetApp Hybrid Cloud Control for your NetApp HCI
installation, when you change your credentials in vCenter and ESXi hosts, you also need
to update those credentials in the asset service on the management node.
About this task
NetApp Hybrid Cloud Control communicates with vCenter and the individual compute nodes running VMware
vSphere ESXi to retrieve information for the dashboard and to facilitate rolling upgrades of firmware, software
and drivers. NetApp Hybrid Cloud Control and its related services on the management node use credentials
(username/password) to authenticate against VMware vCenter and ESXi.
If communication between these components fails, NetApp Hybrid Cloud Control and vCenter display error
messages when authentication problems occur. NetApp Hybrid Cloud Control will display a red error banner if
it cannot communicate with the associated VMware vCenter instance in the NetApp HCI installation. VMware
vCenter will display ESXi account lockout messages for individual ESXi hosts as a result of NetApp Hybrid
Cloud Control using outdated credentials.
The management node in NetApp HCI refers to these components using the following names:
• "Controller assets" are vCenter instances associated with your NetApp HCI installation.
• "Compute node assets" are the ESXi hosts in your NetApp HCI installation.
During the initial installation of NetApp HCI using the NetApp Deployment Engine, the management node
stored the credentials for the administrative user you specified for vCenter and the “root” account password on
ESXi servers.
Update vCenter password by using the management node REST API
Follow the steps to update the controller assets. See View or edit existing controller assets.
