This task is only supported as a staged operation.
Convert To Non-RAID Disk
This task converts a disk to a Non-RAID disk. After converting a disk to non- RAID, the disk is exposed to the operating system
unlike unconfigured good disks and it enables usage of disk in direct pass-through mode.
This task is supported on H310 and H330 controllers.
NOTE: This task is not supported on PERC hardware controllers running in HBA mode.

Creating Virtual Disks
To implement RAID functions, you must create a virtual disk. A virtual disk refers to storage created by a RAID controller from
one or more physical disks. Although a virtual disk may be created from several physical disks, it is seen by the operating system
as a single disk.
Before creating a virtual disk, you should be familiar with the information in Considerations Before Creating Virtual Disks.
You can create a Virtual Disk using the Physical Disks attached to the PERC controller. To create a Virtual Disk, you must have
the Server Control user privilege. You can create a maximum of 64 virtual drives and a maximum of 16 virtual drives in the same
drive group.
You cannot create a virtual disk if:
Physical disk drives are not available for virtual disk creation. Install additional physical disk drives.
Maximum number of virtual disks that can be created on the controller has been reached. You must delete at least one
virtual disk and then create a new virtual disk.
Maximum number of virtual disks supported by a drive group has been created. You must delete one virtual disk from the
selected group and then create a new virtual disk.
A job is currently running or scheduled on the selected controller. You must wait for this job to complete or you can delete
the job before attempting a new operation. You can view and manage the status of the scheduled job in the Job Queue page.
