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 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.
