Users Guide

• Server Configuration Profile feature allows you to configure multiple RAID operations along with setting the controller mode. For
example, if the PERC controller is in HBA mode, you can edit the export xml to change the controller mode to RAID, convert
drives to ready and create a virtual disk.
• While changing the mode from RAID to HBA, the RAIDaction pseudo attribute is set to update (default behavior). The attribute
runs and creates a virtual disk which fails. The controller mode is changed, however, the job is completed with errors. To avoid
this issue, you must comment out the RAIDaction attribute in the XML file.
• When the PERC controller is in HBA mode, if you run import preview on export xml which is edited to change controller mode to
RAID, and try creating a VD, the virtual disk creation fails. Import preview does not support validating stacking RAID operations
with changing controller mode.
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 Overview → Storage → 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.
iDRAC interface supports only 12 Gbps SAS HBA controller and HBA330 internal controller in this release.
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.
