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.
NOTE: Intelligent Mirroring Feature is not supported on PERC 9 controllers and later PERC controllers.
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: 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.
To Reconfigure 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.
NOTE:
For a controller that has more than one channel, it may be possible to configure a virtual disk that is channel-
redundant.
