Overall System Health Status
A webapp sets the value of the Overall System Health Status icon by using a predefined heuristic.
If no webapp can determine the status, the worst possible status is displayed in the Component
Status Summary section.
Component Status summary
The Component Status Summary section displays links to all subsystems that have a critical, major,
minor, or warning status. If there are no critical, major, minor or warning items, the Component
Status Summary section displays no items.
Enclosure
This section provides information about the enclosure cooling, IDs, power, Unit Identification LED,
PCIe devices, and I/O modules.
NOTE: A large number of disk errors may indicate that an I/O module has failed. Inspect the
I/O module LEDs on the storage system and any disk enclosures, and replace any failed component.
• Because both a system and drive fan are required, the maximum and minimum number of
fans required is two. If either fan becomes degraded, the system could shut down quickly.
Because the fans are not mutually redundant, even if the status of a single fan has changed,
the new status is reported immediately in the Components Status Summary section on the SMH
main page.
• When the Enclosure Manager IP address is set incorrectly, the enclosure status displayed is
Lost communication. Because the Enclosure Manager has lost communication with the external
network, none of the other items in the Enclosure Information section can be displayed.
Network
This section shows the status of the network connections.
Storage
This section displays information about the Smart Array and storage controllers within the storage
system. The Storage System page is organized as a left panel and a main page:
