Creating volumes

Perform this task to create volumes using the Create volume panel. Volumes may also be created to add as managed disks (MDisks) to an MDisk group.

If you have installed the Tivoli Storage Area Network Manager, some panels display an additional Create Volume button. Each of these panels features a list of volumes (LUNs and managed disks). After the LUN is created, the LUN list is updated.
