size you specify. The Create Virtual Disk Wizard adjusts the size of the virtual disk to avoid rendering a portion of the
physical disk space unusable.
14. Select a stripe size from the Stripe Element Size drop-down list box. The stripe size refers to the amount of space that
each stripe consumes on a single disk.
15. Select the required read, write, and disk cache policy from the respective drop-down list box. These selections can vary
depending on the controller.
NOTE:
● There is limited support for write policy on controllers that do not have a battery. The cache policy is not supported
on controllers that do not have a battery.
● If you have selected the Create Encrypted Virtual Disk option in Create Virtual Disk Advanced Wizard, then in
the Summary of Virtual Disk Attributes, an Encrypted Virtual Disk attribute is displayed with a value Yes.
16. Click Span Edit to edit the spans created in Create Virtual Disk Advanced Wizard.
CAUTION: If you click Span Edit, Intelligent Mirroring that has already been applied becomes invalid.
NOTE: The Span Edit option is available in the following two cases:
● Only if the controller is a SAS controller with firmware 6.1 and later.
● If you selected RAID 10 while using Create virtual disk Advanced Wizard.
17. If you want to change your selections, click Go Back To Previous Page to return to Create Virtual Disk Advanced

18. Click Finish to complete the virtual disk creation or click Exit Wizard to cancel the virtual disk creation.
The virtual disk is displayed in the Virtual Disk(s) on Controller <Controller Name> page.
For PERC H700 and PERC H800 controllers, if any of the drives you selected 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).
The Create Virtual Disk Advanced Wizard - <Controller Name> page displays a checkbox next to each physical disk that
is suitable as a dedicated hot spare. Select a Physical Disk checkbox if you want to assign a dedicated hot spare.
The Physical Disk checkbox is not available if the controller does not have a physical disk that is a suitable hot spare for
the virtual disk you are creating. For example, the available physical disks may not be sufficient to protect the virtual disk.
If the Physical Disk checkbox is not available, specify a smaller virtual disk, use a different RAID level, or change the disk
selection.
NOTE: If you are creating an encrypted virtual disk, then encrypted physical disks are listed as candidates for hot spare.
RAID configuration by using Unified Server Configurator
The Unified Server Configurators (USC)’s main features include operating system deployment, firmware updates, hardware
configuration, and diagnostics. The UEFI specification creates framework for many powerful applications that run without
an operating system. The UEFI specification includes the Trusted Computing Group (TCG) protocol that allows for Trusted
Platform Module (TPM) measurements and secure updates which USC leverages to its fullest extent.
Steps
1. Select the RAID configuration tab to create the virtual disk as the boot device.
2. On the View Current Configuration screen, you can view a list of current controllers and virtual disks installed in the
system.
a. If the virtual disk or disks exist in the system, click Exit to exit the screen and continue with operating system
installation. if the virtual disk or disks do not exist in the system, continue with the new virtual disk creation process.
3. On the Select RAID Controller screen, select the controller on which to configure a virtual disk.
● If the selected controller contains a foreign configuration, the Foreign Configuration Detected screen is displayed.
