Splitting subdisks
The Split Subdisk command lets you split a subdisk. After the subdisk is split, the resulting two subdisks reside on the same sections of the same disk. You can then use the Move Subdisk command to move one or both subdisks to other disks. You may want to split and move a subdisk to make the best use of your disk space. A split subdisk can be joined back together with the Join Subdisk command.
Note:
Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the Split Subdisk command.
To split a subdisk
- In the tree view, select the volume that contains the subdisks you want to split.
- In the right pane, click the Subdisks tab to display the volume's subdisks.
- Right-click on the subdisk you want to split to bring up its context menu.
- Select Split Subdisk from the context menu.
- In the window that comes up, specify the subdisk size for the first of the two subdisks.
The remaining space is assigned to the second subdisk. For example, if the original subdisk was 100 MB and you assigned 40 MB to the first subdisk, the other subdisk is 60 MB.
The drop-down list to the right of the Size and First subdisk size text entry boxes let you select sectors, KB, MB, GB, or TB.
- Click OK to complete the command.
After a few moments, two subdisks appear in the right pane of the VEA console.
