System Requirements
Make sure that the system meets all system requirements. In particular, verify
that the correct levels of firmware and drivers are installed on the system. For
more information on drivers and firmware, see Drivers and Firmware.
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 support.dell.com.
NOTE: You can verify which firmware and drivers are installed by selecting the
Storage object in the tree view and clicking the Information/Configuration tab. 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 Dell PowerEdge Server
System BIOS on a periodic basis to benefit from the most recent
improvements. For more information, see the Dell PowerEdge 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 attached.
• If the cables are correctly attached 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.
Refer to the hardware device documentation for more information.
Rescan to Update Information on SCSI Controllers
On SCSI controllers, use the Rescan controller task to update information for
the controller and attached devices. This operation may take a few minutes if
there are a number of devices attached to the controller.
If the Rescan does not properly update the disk information, you may need to
reboot your system.
