- Deciding whether to use the System Administration Reference
This guide describes how to administer ONTAP systems. It shows you how to use the CLI interface, how to access the cluster, how to manage nodes, and much more. - Cluster and SVM administrators
Cluster administrators administer the entire cluster and the storage virtual machines (SVMs, formerly known as Vservers ) it contains. SVM administrators administer only their own data SVMs. - ONTAP management interface basics
You can administer the cluster by using the ONTAP command-line interface (CLI) or the web interface. The CLI provides a command-based mechanism that is similar to the Linux tcsh shell. The web interface enables you to use a web browser to manage the cluster. - Cluster management basics (cluster administrators only)
The cluster administrator can set up a new cluster by using the CLI Cluster Setup Wizard. After the cluster is created, the cluster administrator can display the cluster status and attributes, rename the cluster, or assign epsilon to another node in the cluster. - Managing nodes
A node is a controller in a cluster. You can display information about a node, set node attributes, rename a node, add or remove a node, or start or stop a node. You can also manage a node remotely by using the Service Processor (SP). - Managing audit logging for management activities
ONTAP audit logging creates a record of activities that take place on the management interface. The audit logs can be used for monitoring, analysis, and backup purposes. - Managing the cluster time (cluster administrators only)
Problems can occur when the cluster time is inaccurate. Although ONTAP enables you to manually set the time zone, date, and time on the cluster, you should configure the Network Time Protocol (NTP) servers to synchronize the cluster time. - Managing the banner and MOTD
ONTAP enables you to configure a login banner or a message of the day (MOTD) to communicate administrative information to CLI users of the cluster or storage virtual machine (SVM). - Managing licenses (cluster administrators only)
A license is a record of one or more software entitlements. Installing license keys, also known as license codes, enables you to use certain features or services on your cluster. ONTAP enables you to manage feature licenses and monitor feature usage and license entitlement risk. - Managing jobs and schedules
A job is any asynchronous task that is managed by the Job Manager. Jobs are typically long-running volume operations such as copy, move, and mirror. You can monitor, pause, stop, and restart jobs, and you can configure them to run on specified schedules. - Backing up and restoring cluster configurations (cluster administrators only)
Backing up the cluster configuration enables you to restore the configuration of any node or the cluster in the event of a disaster or emergency. - Managing core dumps (cluster administrators only)
When a node panics, a core dump occurs and the system creates a core dump file that technical support can use to troubleshoot the problem. You can configure or display core dump attributes. You can also save, display, segment, upload, or delete a core dump file. - Monitoring a storage system
You can use event messages, the AutoSupport feature, statistics, and environmental component sensors to monitor a storage system. - Managing access to web services
A web service is an application that users can access by using HTTP or HTTPS. The cluster administrator can set up the web protocol engine, configure SSL, enable a web service, and enable users of a role to access a web service. - Verifying the identity of remote servers using certificates
ONTAP supports security certificate features to verify the identity of remote servers. - Contacting Support
You can contact Support to obtain help for your issue. - Notices
