6.5 Changing a Virtual Disk Configuration

You can use the MegaRAID Storage Manager Reconstruction Wizard to change the configuration of a virtual disk.

Caution: Be sure to back up the data on the virtual disk before you change its configuration.

6-24 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, or RAID 50, or RAID 60 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 array. (The Logical View tab shows which arrays and disk drives are used by each virtual disk.)

To start the Reconstruction Wizard, select a virtual disk icon in the left panel of the MegaRAID Storage Manager window, and then select Operations->Advanced Operations->Reconstruction Wizard from the menu. You can also right-click on the virtual disk icon to access the Reconstruction Wizard.

A warning to back up your data appears. Select Confirm and click on Yes.

The Reconstruction Wizard menu appears, as shown in Figure 6.10 Figure 6.10 Reconstruction Wizard
