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 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.
Rebuild Physical Disk
Rebuild Physical Disk is the ability to reconstruct the contents of a failed disk. This is true only when auto rebuild option is set to false. If
there is a redundant virtual disk, the rebuild operation can reconstruct the contents of a failed physical disk. A rebuild can take place during
normal operation, but it degrades performance.
Cancel Rebuild can be used to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a degraded state. The
failure of an additional physical disk can cause the virtual disk to fail and may result in data loss. It is recommended to perform a rebuild on
the failed physical disk at the earliest.
In case, you cancel the rebuild of a physical disk that is assigned as a hot spare, reinitiate the rebuild on the same physical disk in order to
restore the data. Canceling the rebuild of a physical disk and then assigning another physical disk as a hot spare does not cause the newly
assigned hot spare to rebuild the data.
Managing virtual disks
You can perform the following operations for the virtual disks:
• Create
• Delete
