# Enabling or Disabling Root Access for HyperScale 1.5 Reference Architecture

Root access can be disabled on the HyperScale 1.5 Reference Architecture nodes so that only the cvbackupadmin user can log on and access the nodes.

Note

- When root access is disabled, ssh and console login will be prohibited.

- Some operations may require root access. In such situations, temporarily enable root access for all the nodes in the Storage Pool while performing the operation, and then disable root access once the operation is completed.

## Before You Begin

Create a restricted user with a limited set of capabilities (or commands) needed to administer the cluster.

## Procedure

1. From the Command Center navigation pane, go to Manage > Storage > HyperScale X.

   The HyperScale X page appears.

2. Click the hyperscale storage cluster to disable root access.

   The hyperscale storage page appears.

3. In the Nodes section, for each node that you want to disable root access, click the action button , and then click Disable Root Access.

   Repeat the step from all the nodes in the storage pool.

   If necessary, to enable root access click the action button , and then click Enable Root Access. (This option will be available only when the root access is disabled.)
