NOTE: When you change the controller mode from RAID to HBA or from HBA to RAID, certain features or functionality
may vary.
1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2. Select the Controller object.
3. Click Information/Configuration on the controller Properties page.
4. In the Controller Tasks drop-down menu, select Change Controller Mode..., and then click Execute.
The Change Controller Mode window is displayed. The Current Controller Mode section displays the mode of the controller –

Auto Configure RAID0 Operation
Does my controller support this feature? See Supported Features.
You can use this feature to automatically configure all physical disks in Ready state into RAID 0 virtual disks. This feature is supported on
PERC 9 family of hardware controllers with the latest firmware version.
NOTE:
The Auto Configure RAID0 operation is only supported on SAS and SATA HDDs. If there are any SSDs available in
the server, this feature ignores the SSDs when performing the Auto Configure RAID0 operation.
NOTE: When performing an Auto Configure RAID0 operation on a single storage controller, the maximum number of
physical disks supported is 192. Only physical disks in Ready state are configured into RAID 0 virtual disks.
Before you proceed, browse to the physical disks details page and verify if the physical disks are in Ready state. To configure physical
disks into RAID 0 virtual disks, perform the following steps:
1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2. Select the Controller object.
3. Click Information/Configuration on the controller Properties page.
