Virtual Disks 259
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 that
span and selecting a new physical disk to comprise that span.
To successfully create a virtual disk, a minimum of two spans must exist at all
times.
NOTE: If you click 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 Linux operating systems, if you do a reconfigure on the same controller
on which the operating system resides, you may experience extremely slow system
performance until the reconfiguration is complete.
NOTE: You may want to review Virtual Disk Considerations for Controllers. This
section contains considerations that also apply to reconfiguring a virtual disk on
these controllers.
