5. Click Finish to complete 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).
Click Go Back To Previous Page to return to Create Virtual Disk Advanced Wizard page, if you want to change your selections.
Click Exit Wizard to cancel the virtual disk creation.
The Create Virtual Disk Advanced Wizard (Step 3 of 3) - <Controller Name> page displays a check box next to each physical disk
that is suitable as a dedicated hot spare. Select a Physical Disk check box if you want to assign a dedicated hot spare
The Physical Disk check box 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 be too small to protect the virtual disk. If the Physical Disk check box is
not available, you may need to 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.

Span Edit
In the edit mode, you cannot alter the number of physical disks per span. If there are enough available physical disks, you can reduce or
increase the number of spans. You can also alter the contents of a span by removing the span and selecting a new physical disk to
comprise that span.
To successfully create a virtual disk, a minimum of two spans must exist always.
NOTE: If you select Span Edit, Intelligent Mirroring that is already been applied becomes invalid.
Virtual Disk Task: Reconfigure (Step 1 of 3)
Does my controller support this feature? See Supported Features.
The Reconfigure task enables you to change the virtual disk configuration. Using this task, you can change the RAID level and increase
the virtual disk size by adding physical disks. On some controllers, you can also remove physical disks.
Before continuing with the virtual disk reconfiguration, you should be familiar with the information in Starting And Target RAID Levels For
Virtual Disk Reconfiguration And Capacity Expansion and Choosing RAID Levels And Concatenation.
NOTE: You cannot reconfigure a virtual disk on a controller that is operating in cluster mode.
NOTE: You can create no more than 64 virtual disks on a controller. After you have reached this limit, you can no longer
reconfigure any of the virtual disks on the controller. But, for IR and PERC H200 controllers, you can create only two
virtual disks.
NOTE: On systems running the Linux operating system, if you reconfigure the same controller on which the operating
system resides, you may experience extremely slow system performance until the reconfiguration is complete.
NOTE: If you want to reconfigure a virtual disk with an additional physical disk, the physical disk must be of supported
bus protocol, media type, sector size, T10 Protection Information capability, and encryption capability.
