Information Update 3

RAID Configuration Update

Host-based RAID configuration is supported using Dell PowerEdge RAID

Controller (PERC) 5/E and PERC 6/E.

Supported Hardware Configurations Using a

PERC 6/E Adapter

PERC 6/E adapters can detect and use redundant paths to drives in a Dell

PowerVault MD1000 enclosure. With redundant paths, if one path fails,

another path can be used to communicate between the controller and the

hard drive.

NOTE: Redundant path connectivity is not supported on PERC 5/E adapters.

Information Update 5

Additional Information for Troubleshooting a

SAS/SATA drive

Reseating a drive during initial set up is a valid step. If an enclosure is in

production and if there are no problems other than non-detection of a drive,

replace the drive that is not detected rather than reseating the drive.

It is recommended not to reseat a SMART tripped or failed drive. You cannot

reset a SMART tripped drive back to normal state. If a drive fails due to the

controller, check if a new firmware is available to fix the issue. If a firmware

update does not fix the issue, replace the drive.

NOTE: If an amber blink sequence represents a SMART trip, the drive must be

replaced. It cannot be fixed by a firmware update.

For more information about troubleshooting a SAS/SATA drive, see the Dell

PowerVault MD1000 Storage Enclosure Hardware Owner’s Manual at

support.dell.com/manuals.

Troubleshooting Enclosure Problems

Problem

One of the temperature probes displays an abnormal temperature reading.

Action

The system management software displays four temperature probes (0-3).

Probe 0 represents the temperature sensor on

enclosure management module

(

EMM) 0. Probe 1 represents the temperature sensor on EMM1. Probe 2 and

3 are temperature sensors on the midplane.

To resolve this issue:

• Check for airflow obstruction.

• Replace the component with the abnormal temperature sensor.

NOTE: The power supplies do not have a temperature sensor that reports to the

system management software.

使用 PERC 6/E 适配器支持的硬件配置

PERC 6/E 适配器可检测和使用指向 Dell PowerVault MD1000 机柜中的驱

动器的冗余路径。借冗余路径，如果一条路径发生故障，则可使用另一

条路径来保持控制器与硬盘驱动器之间的通信。
