Configuration validation of Dell EMC PowerEdge R750
The new generation of PowerEdge systems of Dell EMC PowerEdge R750 have added interconnect flexibility and advanced iDRAC management features to collect precise system configuration information and report configuration errors.
When the system is powered on, information about installed cables, risers, backplanes, floating card (fPERClike BOSS), and processor is obtained from the CPLD and backplane memory maps is analyzed. This information forms a unique configuration, which is compared with one of the qualified configurations stored in a table maintained by iDRAC.
One or more sensors are assigned to each of the configuration elements. During POST, any configuration validation error is logged in the System Event Log (SEL)/LifeCycle (LC) log. The reported events are categorized in the configuration validation error table.
Table: Configuration validation error
| ERROR | DESCRIPTION | POSSIBLE CAUSE AND RECOMMENDATIONS | EXAMPLE |
| Message | A configuration element within the closest match contains something that is unexpected and does not match any Dell qualified configuration. | Wrong configuration | Config Error: Backplane cable CTRS_SRC_SA1 and BP-DST_SA1 |
| The element reported in HWC8010 errors are assembled incorrectly. Verify element (cable, risers, etc) placement in the system. | Config Error : SL Cable PLANAR_SL7 and CTRL_DST_PA1 | ||
| Config Missing | iDRAC found a configuration element missing within the closest match detected. | Missing or damaged cable, device, or part | Config Missing: Float card front PERC/HBA |
| Missing element or cable is reported in HWC8010 error logs. Install the missing element (cable, risers, etc). | Config Missing : SL cable PLANAR_SL8 and CTRL_DST_PA1 |
| Comm Error | A configuration element is not responding to iDRAC using the management interface while running an inventory check. | System management sideband communication | Comm Error: Backplane 2 |
| Unplug AC Power, reseat the element and replace the element if the problem persists. |
