For information on these properties, see Understanding Virtual Disk Parameters. 5 Click Go to accept the changes. Changing a Virtual Disk Configuration You can use the Dell SAS RAID Storage Manager Reconstruction Wizard to change the configuration of virtual disks on a Dell system with a PERC 5/i controller or a PERC 6/i controller. You can change the configuration for virtual disks at the following RAID levels for these RAID controllers: • PERC 5/i controller: RAID 0, RAID 1, and RAID 5 • PERC 6/i controller: RAID 0, RAID 1, RAID 5, and RAID 6 NOTICE: Be sure to back up the data on the virtual disk before you change its configuration. The Reconstruction Wizard allows you to change a virtual disk configuration by adding disk drives to the virtual disk, removing disk drives from it, or changing its RAID level. NOTE: You cannot change the configuration of a RAID 10 virtual disk. You cannot change a RAID 0, RAID 1, RAID 5, or RAID 6 configuration if two or more virtual disks are defined on a single disk group. (The Logical view tab shows which disk groups and disk drives are used by each virtual disk.) 38 Configuration

Changing a Virtual Disk Configuration
You can use the Dell SAS RAID Storage Manager Reconstruction Wizard to
change the configuration of virtual disks on a
Dell system with a PERC 5/i
controller or a PERC 6/i controller
. You can change the configuration for
virtual disks at the following RAID levels for these RAID controllers:
PERC 5/i controller: RAID 0, RAID 1, and RAID 5
PERC 6/i controller: RAID 0, RAID 1, RAID 5, and RAID 6
NOTICE:
Be sure to back up the data on the virtual disk before you change its
configuration.
The Reconstruction Wizard allows you to change a virtual disk configuration
by adding disk drives to the virtual disk, removing disk drives from it, or
changing its RAID level.
NOTE:
You cannot change the configuration of a RAID 10 virtual disk. You cannot
change a RAID 0, RAID 1, RAID 5, or RAID 6 configuration if two or more virtual
disks are defined on a single disk group. (The Logical view tab shows which disk
groups and disk drives are used by each virtual disk.)
