Drivers And Firmware
Storage Management is tested with the supported controller firmware and drivers. In order to function
properly, the controller must have the minimum required version of the firmware and drivers installed.
The most current versions can be obtained from the support site.
NOTE: You can verify which firmware and drivers are installed by selecting the Storage object in the
tree view and clicking Information/Configuration. You can also check the Alert Log for alerts
relating to unsupported firmware and driver versions.
It is also recommended to obtain and apply the latest server system BIOS on a periodic basis to benefit
from the most recent improvements. For more information on server system BIOS, see the system
documentation.
Isolate Hardware Problems
If you receive a timeout alert related to a hardware device or if you otherwise suspect that a device
attached to the system is experiencing a failure, then to confirm the problem:
• Verify that the cables are correctly connected.
• If the cables are correctly connected and you are still experiencing the problem, then disconnect the
device cables and reboot the system. If the system reboots successfully, then one of the devices may
be defective. For more information on hardware, refer to the hardware device documentation.
