l "System Requirements"
l "Drivers and Firmware"
l "Isolate Hardware Problems"

Cables Attached Correctly
Verify that the power-supply cord and adapter cables are attached correctly. If the system is having trouble with read and write operations to a particular
virtual disk or non-RAID physical disk (if the system hangs, for example), then make sure that the cables attached to the corresponding enclosure or backplane
are secure. If the connection is secure but the problem persists, you may need to replace a cable. See also "Isolate Hardware Problems."
On SAS controllers, you should verify that the cable configuration is valid. Refer to the SAS hardware documentation for valid cable configurations. If the cable
configuration is invalid, you may receive alerts 2182 or 2356.
For information on Alert Messages, see the Dell OpenManage Server Administrator Messages Reference Guide on the Dell Support website at
support.dell.com/manuals.

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 the Dell™ Support website at support.dell.com.

Please refer to the Dell PowerEdge system documentation for more information.

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 do
the following to confirm the problem:
l Verify that the cables are correctly attached.
l 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
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.
