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. For more information about the commands, see the iDRAC RACADM Command Line Reference Guide available at dell.com/ idracmanuals. Managing virtual disks You can perform the following operations for the virtual disks: • Create • Delete • Edit policies • Initialize • Check consistency • Cancel check consistency • Encrypt virtual disks • Assign or unassign dedicated hot spares • Blink and unblink virtual disks NOTE: You can manage and monitor 192 virtual disks if auto-configuration is enabled through PERC controller BIOS, Human Interface Infrastructure (HII), and Dell OpenManage Server Administrator (OMSA).

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 reached. 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. • Physical disk is in non-RAID mode. You must convert to RAID mode using iDRAC interfaces such as iDRAC web interface, RACADM, WSMAN, or . Managing storage devices 193
