Dell Customer Communication - Confidential ALERTS The Alerts page, as shown in Figure 28, displays all system-generated alerts along with associated message information. Alerts are usually events that require attention from the user in some manner. Some alerts indicate that there is a problem or issue with the system, while others provide specific information, depending on the system status. For example, an alert might indicate that a drive has faulted or a specific pool is out of space, which means some type of action would be needed to remedy the event. Alerts provide the user with information about the source of an event, the symptoms and cause, and actions to resolve it. Sometimes they include a Knowledge Base (KB) article link. If an alert is known or no longer relevant to the environment, the Alerts page provides a way to acknowledge alerts for book-keeping purposes as well as the ability to delete alerts as needed. Users can also configure Unisphere to send alert notifications to a specified email or SNMP trap via the Settings menu. Figure 28. Alerts Page Each alert is associated with a severity level; definitions are shown below in Table 4: ICON LABEL Table 4. Alert severity levels INDICATES Information An event has occurred that does not impact system functions. No action is required. Warning Error Critical An error has occurred that you should be aware of, but it does not have a significant impact on the system. For example, a component is working, but its performance may not be optimum. An error has occurred that has a minor impact on the system and should be remedied, but it does not have to be fixed immediately. For example, a component is failing and some or all of its functions may be degraded or not working. An error has occurred that has a significant impact on the system, and it should be remedied immediately. For example, a component is missing or has failed and recovery may not be possible. JOBS As task operations are run on the system, the system records the operations through the Jobs page in Unisphere, Figure 29 shows the Jobs page in Unisphere with all the entries. Most operations for storage systems are automatically run as background jobs, allowing users to start other tasks without waiting for a certain job to complete first. At any given point, users can view the full list of running, queued, completed, or failed jobs from the Jobs page. To get more information about a job, users can select the job and click the details icon to see related tasks/descriptions for the specific job. Unisphere also provides users the ability to cancel running jobs as needed. This only stops subsequent related job tasks from running and does not revert the jobs that have already completed. Job listings can be deleted from the list so they are no longer shown. Deleting jobs is not currently supported through the GUI, see the Known issues section for more details. Deleting a job from the list does not revert the actions that were completed. In this release, canceling and deleting jobs is only supported in the CLI. Please refer to the CLI section for further details. 20

ALERTS
The Alerts page, as shown in Figure 28, displays all system-generated alerts along with associated message information. Alerts are
usually events that require attention from the user in some manner. Some alerts indicate that there is a problem or issue with the
system, while others provide specific information, depending on the system status. For example, an alert might indicate that a drive
has faulted or a specific pool is out of space, which means some type of action would be needed to remedy the event. Alerts provide
the user with information about the source of an event, the symptoms and cause, and actions to resolve it. Sometimes they include a
