Pressing <Ctrl+R> while restarting the server and selecting the required controller.
NOTE: If the physical drives connected to a PERC controller are in non-RAID mode, the size of the disk displayed in the
iDRAC interfaces, such as iDRAC GUI, RACADM, Redfish and WSMan, may be slightly less than the actual size of the disk.
However, you can use the full capacity of the disk to deploy operating systems.
NOTE: Hot plugged disks in H330 are always in non-RAID mode. In other RAID controllers, they are always in RAID mode.
Converting physical disks to RAID capable or non-RAID mode using the
iDRAC web interface
To convert the physical disks to RAID mode or non-RAID mode, perform the following steps:
1. In the iDRAC web interface, click Storage > Overview > Physical Disks.
2. Click Advanced Filter.
An elaborated list is displayed that allows you to configure different parameters.
3. From the Group By drop-down menu, select an enclosure or virtual disks.
The parameters associated with the enclosure or the VD are displayed.
4. Click Apply, once you select all the desired parameters. For more information about the fields, see the iDRAC Online Help.
The settings are applied based on the option selected in the operation mode.
Converting physical disks to RAID capable or non-RAID mode using RACADM
Depending on whether you want to convert to RAID or Non-RAID mode, use the following RACADM commands
To convert to RAID mode, use the racadm storage converttoraid command.
To convert to Non-RAID mode, use the racadm storage converttononraid command.
NOTE:
On the S140 controller, you can only use the RACADM interface to convert the drives from non-RAID to RAID mode.
The supported Software RAID modes are Windows or Linux Mode.
For more information about the commands, see the iDRAC RACADM CLI Guide available at https://www.dell.com/idracmanuals.
Instant Erase Secured Physical Disk
Instant Erase Secured Physical Disk ensures the ability to securely erase the contents on a physical Self Encrypting Drives. This
feature is also supported for ISE drives. The NVMe PCIe SSDs also support cryptographic erase operation along with SED and
ISE drives.
The data still resides on the physical Self Encrypting Drives and ISE drives even after all the virtual disks are deleted. This poses
a security risk with data still being on the physical disk. This feature allows the user to securely erase or delete all the data on
Self Encrypting Drives and ISE drives. Using this feature, the user is able to erase all SEDs and ISE drives which are connected
to a PERC.
NOTE: At this point, you can use the System Erase option to securely erase all ISE drives.
This feature is not available in the following conditions:
When a physical disk is already used by a VD.
When the selected physical disk is neither SED nor ISE drive
When the physical disk is used as a hot spare.
This feature is available for:
Unconfigured SED drive and ISE drive
Foreign configured encrypted drive
Unconfigured and Foreign Drive even when an Encryption Key is not present in the controller
NOTE:
Cryptographic Erase Use this option against every SED and ISE physical disk to securely erase the SED and ISE
physical disk. This configuration is supported by both staged and realtime.
