Expanding volumes
You can expand the size of a volume from one of the following:
- Volumes table (Provisioning > Volumes)—Select the volume and choose Expand Volumes from the drop-down list.
- Overview panel (Provisioning > Volumes > slide-over > Overview > Expand Volume)
- Data Protection table (Provisioning > Volumes > Data Protection > slide-over > Overview > Expand Volume)—Follow the on-screen directions to complete the action.
NOTE:From the slide-over you can only expand the selected volume (the volume for which the slide-over is opened).
The top portion of the panel displays a color-coded graph for each pool on the system or volume usage by disk group. The graph indicates the amount of space on the system that is allocated to volumes; the total volumes committed (reserved for the system but not written to); the space occupied by added volumes; the space required for the new volume you are creating; unused available space; and the space that is overcommitted if the Pool Overcommit setting is enabled.
Volume sizes are aligned to 4.2-MB (4-MiB) boundaries. When a volume is created or expanded, the resulting size will be decreased to the nearest 4.2-MB boundary
NOTE:If overcommitting the physical capacity of the system is enabled, the system will warn you via alerts (and event 462) before the pool runs out of physical storage.
NOTE:You can expand the base volume of a snapshot tree, but you cannot expand any snapshots in the tree.
