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.

To Recongure A Virtual Disk: Step 1 of 3
1. Select the physical disks that you want to include in the virtual disk. You can expand the capacity of the virtual disk by adding
additional physical disks. On some controllers, you can also remove physical disks.
The changes you make to the physical disk selection are displayed in the Selected Physical Disks table.
