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 Action > Edit.
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 At Next Reboot.
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>]
● To create a job and apply changes:
$ racadm jobqueue create <Controller Instance ID> -s TIME_NOW -r pwrcycle
For more information, see the iDRAC RACADM Command Line Interface Reference Guide available at dell.com/idracmanuals.
12 Gbps SAS HBA adapter operations
Dell PowerEdge servers must have an operating system installed and the appropriate device driver to be loaded in order for Dell
HBAs to operate. Following POST, the HBA ports will be disabled. The HBA device driver is responsible for resetting the HBA
and enabling its ports connected to storage devices. Without an operating system, the driver will not be loaded, and there is no
guarantee that iDRAC will be able to display storage devices connected to Dell HBAs.
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, HBA330 (integrated and adapter) controllers, HBA330 MMZ, and
HBA330 MX adapters.
AMD platforms support HBA355i front and HBA355i 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:
● Enable Collect System Inventory On Reboot (CSIOR) operation before inventorying or monitoring the non-RAID
controllers.
● 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.
