Create Virtual Disk Advanced Wizard (Step 2)
Depending on the RAID level you selected in the Create Virtual Disk Wizard (Step 1) <Controller Name> page, the Create
Virtual Disk Advanced Wizard (Step 2 of 3) - <Controller Name> page displays the disks and connectors (channels or
ports) available for configuring the virtual disk.
NOTE: If you are creating an encrypted virtual disk, only the encrypted physical disks are displayed. Else, both
encrypted and unencrypted physical disks are displayed.
The following is an example of what might be displayed:
Connector 0
The Connector section of the page displays the connectors on the controller and the disks attached to each connector.
Select the disks you want to include in the virtual disk. In this example, the controller has a single connector with five
disks.
• Physical disk 0:0
• Physical disk 0:1
• Physical disk 0:2
• Physical disk 0:3
• Physical disk 0:4
Physical Disks Selected
The Physical Disks Selected section of the page displays the disks you have chosen. In this example, two disks are
selected.
• Physical disk 0:0
• Physical disk 0:1
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 the number of disks that 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:
• All Disks — Enables you to select all the physical disks in all the enclosures.
• Enclosure — Enables you to select all physical disks in the enclosure.
NOTE: The All Disks and Enclosure options enable you to edit spans after selecting the physical disks that
comprise them. You can remove a span and specify a span again with different physical disks before proceeding.
• 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.
NOTE: This option is available only if the Intelligent Mirroring on the Create Virtual Disk Advanced Wizard
(Step 2 of 3) 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.
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 are not part of RAID 10.
• Select the number of disks to create a single spanned virtual disk list box — Enables you to create a single span
virtual disk with 22 or 26 physical drives for PERC controllers. This list box option appears only if you have
selected RAID 10 in step 1 and the system has 22 or more physical drives.
