Users Guide
Component status is indicated by the severity. A component with a Warning or Critical/Failure status requires immediate attention to avoid data loss, if
possible. A component's status may indicate the combined status of the component and its lower-level objects. See "Determining the Health Status for
Storage Components" for more information.
It may be useful to review the Alert Log for events indicating why a component has a Warning or Critical status. For additional troubleshooting information,
see "Alert Messages" and "Troubleshooting."
Storage Properties and Current Activity
The Configuration/Information subtab displays information regarding a storage component. These properties include details such as the number of connectors
(channels or ports) on a controller or the Enclosure Management Modules (EMM) firmware version.
The State and Progress properties indicate a component's current activity. For example, an offline physical disk displays the Offline status while the Progress
property displays how close to completion an operation (such as a rebuild) is.
The following sections describe the properties for each component:
l "Storage Information and Global Tasks"
l "Controller Properties and Tasks"
l "Battery Properties and Tasks"
l "Connector Properties and Tasks"
l "Enclosure and Backplane Properties and Tasks"
l "Physical Disk Properties and Tasks"
l "EMM Properties"
l "Fan Properties"
l "Power Supply Properties"
l "Temperature Probe Properties and Tasks"
l "Virtual Disk Properties and Tasks"
Alerts or Events
Storage activity generates alerts or events that are displayed in the Alert Log. Some alerts indicate normal activity and are displayed for informational
purposes only. Other alerts indicate abnormal activity which should be addressed immediately. For more information about alerts and their corrective actions,
see "Alert Messages."
Monitoring Disk Reliability on RAID Controllers
Storage Management supports Self Monitoring Analysis and Reporting Technology (SMART) on physical disks that are SMART-enabled.
Severity
Component Status
Normal/OK. The component is working as expected.
Warning/Non-critical. A probe or other monitoring device has detected a reading for the component that is above or below the acceptable
level. The component may still be functioning, but it could fail. The component may also be functioning in an impaired state. Data loss is possible.
Critical/Failure/Error. The component has either failed or failure is imminent. The component requires immediate attention and may need to be
replaced. Data loss may have occurred.
