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.

Using Enclosure Temperature Probes
Physical disk enclosures have temperature probes that warn you when the enclosure has exceeded an acceptable temperature
range.

Time Delay In Displaying Conguration Changes
When you change the storage conguration, Storage Management quickly generates SNMP traps in response to the conguration
changes. The Storage Management, Management Information Base (MIB) is also updated to reect storage conguration changes.
However, it may take up to ve minutes to update the MIB with the most recent storage conguration. For this reason, there is a
time delay of up to ve minutes between the receipt of an SNMP trap and the ability to identify the conguration changes by
querying the Storage Management MIB. This time delay is notable when creating a new virtual disk or performing an unmirror or split
mirror on a RAID 1-concatenated virtual disk.
