Switching the controller mode using the iDRAC web interface
To switch the controller mode, perform the following steps:
1. In the iDRAC web interface, click Storage > Overview > Controllers.
2. On the Controllers page, click Setup > Controller Mode.
The Current Value column displays the current setting of the controller.
3. From the drop-down menu, select the controller mode you want to switch to, and click Apply.
Reboot the system for the change to take effect.
Switching the controller mode using RACADM
To switch the controller mode using RACADM, run the following commands.
To view the current mode of the controller:
$ racadm get Storage.Controller.1.RequestedControllerMode[key=<Controller_FQDD>]
The following output is displayed:
RequestedControllerMode = NONE
To set the controller mode as HBA:
$ racadm set Storage.Controller.1.RequestedControllerMode HBA [Key=<Controller_FQDD>]
For more information, see the iDRAC RACADM Command Line Interface Reference Guide available at dell.com/idracmanuals.
12 Gbps SAS HBA adapter operations
The non-RAID controllers are the HBAs that do not have few RAID capabilities. They do not support virtual disks.
14G iDRAC interface supports 12 Gbps SAS HBA controller, and HBA330 (integrated and adapter) controllers.
You can perform the following for non-RAID controllers:
View controller, physical disks, and enclosure properties as applicable for the non-RAID controller. Also, view EMM, fan,
power supply unit, and temperature probe properties associated with the enclosure. The properties are displayed based on
the type of controller.
View software and hardware inventory information.
Update firmware for enclosures behind the 12 Gbps SAS HBA controller (staged)
Monitor the polling or polling frequency for physical disk SMART trip status when there is change detected
Monitor the physical disks hot plug or hot removal status
Blink or unblink LEDs
NOTE:
You must perform Collect System Inventory On Reboot (CSIOR) operation before inventorying or monitoring the
non-RAID controllers.
Reboot the system after performing a firmware update.
Real-time monitoring for SMART enabled drives and SES enclosure sensors is only done for the 12 Gbps SAS HBA
controllers and HBA330 internal controllers.
Monitoring predictive failure analysis on drives
Storage management supports Self Monitoring Analysis and Reporting Technology (SMART) on physical disks that are SMART-
enabled.
SMART performs predictive failure analysis on each disk and sends alerts if a disk failure is predicted. The controllers check
physical disks for failure predictions and, if found, pass this information to iDRAC. iDRAC immediately logs an alert.
