Troubleshooting SAS RAID controller module issues

The BladeCenter® S chassis is the first BladeCenter chassis to provide integrated hard drives within the chassis that can be shared by all blade servers within the chassis.

You must install the following to take advantage of this capability:

Two SAS RAID controller modules must be installed, one in I/O module bay 3 and one in I/O module bay 4. The SAS RAID controller module provides integrated SAS switch and RAID controller capability.
A SAS expansion card option must be installed in each blade server that will access the integrated shared storage.
SAS hard disk drives must be installed in the storage modules. SATA hard disk drives are not supported.
Both battery backup units must be installed in the bays in the media tray.

For additional information about the SAS RAID controller module, see the BladeCenter S SAS RAID Controller Module Installation and User's Guide.

Problem Determination capabilities are built into the SAS RAID controller and connected back through the advanced management module to provide a more unified system structure. SAS RAID controller module alerts are mapped to the advanced management module events. If appropriate, these alerts can also generate a call home.

For rapid problem determination and resolution, the SAS RAID controller module maintains its own set of alerts in an active alert list based on the events and configuration in the RAID controller.

Typically, alerts that require user intervention will turn on the Information LED on the SAS RAID controller module. The active alert list, the alert history log, and the user’s guide provide necessary information for problem analysis and resolution. In addition, the SAS RAID controller module provides its own independent alerting, such as e-mail notification.

If you see an event related to the SAS RAID controller module through the advanced management module, you can log in to the SAS RAID controller module interface (or use Storage Configuration Manager) to obtain more information.
