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 dierent 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 - Recongure Step 1 of 3
Does my controller support this feature? See Supported Features.
The Recongure task enables you to change the virtual disk conguration. 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 reconguration, you should be familiar with the information in Starting And Target RAID Levels For
Virtual Disk Reconguration And Capacity Expansion and Choosing RAID Levels And Concatenation.
NOTE
: You cannot recongure 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
recongure 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 recongure the same controller on which the operating system
resides, you may experience extremely slow system performance until the reconguration is complete.
NOTE: You may want to review Virtual Disk Considerations For Controllers. This section contains considerations that also apply
to reconguring a virtual disk on these controllers.
