The State and Progress properties display the current activity of a component. 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:
• Storage Information And Global Tasks
• Battery Properties And Tasks
• Connector Properties And Tasks
• Enclosure And Backplane Properties And Tasks
• Physical Disk Or Physical Device Properties
• Physical Disk Or Physical Device Tasks
• EMM Properties
• Fan Properties
• Power Supply Properties
• Temperature Probe Properties And Tasks
• 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
must be addressed immediately. For more information about alerts and their corrective actions, see the
Server Administrator Messages Reference Guide.
Monitoring Disk Reliability On RAID Controllers
Storage Management supports Self Monitoring Analysis and Reporting Technology (SMART) on physical
disks that are SMART-enabled.
SMART performs predictive failure analysis on each disk and sends alerts if a disk failure is predicted. The
RAID controllers check physical disks for failure predictions and, if found, pass this information to Storage
Management. Storage Management immediately displays an alert icon on the disk. Storage Management
also sends an alert to the Alert Log and the Microsoft Windows application log.
NOTE: You may not receive SMART alerts when the I/O of a controller is paused.
Using Alarms To Detect Failures
Certain storage components have alarms which when enabled, alert you when the component fails.
