NOTE: When you create virtual disks, you might want to consider how virtual disks will be
deleted. Virtual disks created on the PERC 3/DC or PERC 3/QC controller must be deleted in
reverse order of their creation. In other words, you must delete the most recently created virtual
disk first and continue to delete in reverse order.
NOTE: To take advantage of all the system features such as
Defrag
and
Encryption
, you are
recommended to use the default value of 64 KB for the stripe size when creating a virtual disk.
To create a virtual disk, perform the following steps:
1
Right-click on an array group.
2
Click Create Virtual Disk to launch the Create Virtual Disk Wizard .
3
Read the Welcome screen and click Next to continue.
The Select Creation Mode dialog box displays. You can cancel the operation at any
time by clicking Cancel .
4
Select Custom Mode and click Next to continue.
The Select Disks and Virtual Disk Attributes screen displays.
5
Select the disks and confirm information presented in the wizard.
NOTE:
The PowerVault 750N and 755N only supports NTFS partitions. Formatting all
partitions NTFS allows for advanced features only available under that file system.
6
Click Next to continue.
The Completing the Create Virtual Disk Wizard dialog box displays.
7
Click Finish to create a virtual disk or Back to return to the previous screen.
Array Manager confirms the creation of the virtual disk.
The Rescan Disk Layout checkbox is selected by default. Rescan Disk Layout allows
the Microsoft
®
Windows
®
Powered operating system to recognize the new virtual
disk. You can perform a Rescan Disk Layout later if the box is not checked when you
create the virtual disk.
Deleting Virtual Disks
Deleting a virtual disk permanently deletes all information contained on that disk. Virtual
disks created on the PERC 3/DC or PERC 3/QC controller must be deleted in the reverse
order that they were created. In other words, the last disk that you created must be deleted
first.
NOTICE:
All data on the virtual disk is lost when the disk is deleted.
