Connector 0
The Connector section of the screen displays the controller's connectors and the disks attached to each connector. Select the disks to be included in the virtual
disk. In this example, the controller has a single connector with five disks.

Physical Disks Selected
The Physical Disks Selected section of the screen displays the disks you have chosen. In this example, two disks are selected.

Each RAID level has specific requirements for the number of disks that must be selected. RAID 10, RAID 50, and RAID 60 also have requirements for how many
disks must be included in each stripe or span.
If the controller is a SAS controller with firmware versions 6.1 and later and you selected RAID 10, RAID 50, and RAID 60, the user interface displays the
following:
l Select All Disks check box—Enables you to select all the physical disks in all the enclosures.
l Enclosure check box—Enables you to select all physical disks in the enclosure.
l Select Number of Disks per Span—Enables you to select the number of disks in each span (default =2). This option is available only on SAS controllers
with firmware version 6.1 and later.
Let us consider that the controller has three enclosures with six physical disks each (total number of available disks = 3 x 6 =18 disks). If you select four
disks per span, the controller creates four spans (18 disks/4 disks per span = 4 spans). The last two disks of the last enclosure is not part of RAID 10.
Select the number of disks to create a single spanned virtual disk drop down menu—Enables you to create a single span virtual disk with 22 or 26
physical drives for PERC controllers. This drop down menu appears only if you have selected RAID 10 in step 1 and the system has 22 or more than 22
physical drives.
Click Continue when you have completed the disk selection. If you want to cancel the virtual disk, click Exit Wizard. If you want to return to the previous
screen and change your selections, click Go Back To Previous Page.
For PERC H700 and PERC H800 controllers, if any of the drives you selected to include as a hot spare is in the spun down state, the following message is
displayed: The below listed physical drive(s) are in the spun down state. Executing this task on these drive(s) takes additional time, because the drive(s) need
to spun up. The message displays the ID(s) of the spun down drive(s).
Create Virtual Disk Advanced Wizard (Step 3 of 4)

Does my controller support this feature? See Supported Features.
This screen enables you to select attributes for the virtual disk. These attributes include the name, size and read, write, and cache policy. Depending on the
controller and your previous virtual disk selections, the items displayed on this screen can vary.
Do the following:

1. Type the name of the virtual disk in the Name text box.
The virtual disk name can contain only alphanumeric characters as well as spaces, dashes and underscores. The maximum name length depends on the
controller. In most cases, the maximum length is 15 characters. The name cannot start with a space or end with a space.
It is recommended that you specify a unique name for each virtual disk. If you have virtual disks with the same name, it is hard to differentiate the alerts
generated for these virtual disks.

NOTE: The Select All and Enclosure check boxes enable you to edit spans after selecting the physical disks that comprise them. You can remove
a span and re-specify a span with different physical disks before proceeding.
NOTE: This option is available only if you did not select Intelligent Mirroring on the Create Virtual Disk (Step 1 of 4) page.
NOTE: On a SAS controller with firmware version 6.1 and later, RAID 10 supports only even number of disks per span and a maximum of 8 spans
with 32 disks in each span.
NOTE: The CERC SATA1.5/2s controller does not allow you to specify a name for concatenated virtual disks. The concatenated virtual disk is created with
a default name.
