• LUN. Volume identifier presented to the host.
• Access. Volume access type: read-write, read-only, no-access (masked), or not-mapped.
To create an explicit mapping
1. In the Maps for Volume table, select the Default mapping to change. The mapping options appear.
2. Select Map.
3. Set the LUN and select the access type and ports.
4. Click Apply. A message specifies whether the change succeeded or failed.
5. Click OK. The mapping becomes Explicit with the new settings.
To modify an explicit mapping
1. In the Maps for Volume table, select the Explicit mapping to change. The mapping options appear.
2. Set the LUN and select the access type and ports.
3. Click Apply. A message specifies whether the change succeeded or failed.
4. Click OK. The mapping settings are updated.
To delete an explicit mapping
1. In the Maps for Volume table, select the Explicit mapping to delete. The mapping options appear.
2. Clear Map.
3. Click Apply. A message specifies whether the change succeeded or failed.
4. Click OK. The mapping returns to being a Default mapping.
Expanding a volume
You can expand a standard volume if its vdisk has free space and sufficient resources. Because volume
expansion does not require I/O to be quiesced, the volume can continue to be used during expansion.
To expand a volume
1. In the Configuration View panel, right-click a volume and select Tools > Expand Volume.
2. In the main panel, specify the amount of free space to add to the volume.
3. Click Expand Volume. If the specified value exceeds the amount of free space in the vdisk, a dialog lets
you expand the volume to the limit of free space in the vdisk. If the task succeeds, the volume's size is
updated in the Configuration View panel.
Creating multiple snapshots
You can select multiple volumes and immediately create a snapshot of each volume.
To create multiple snapshots
1. In the Configuration View panel, right-click the system or Vdisks or a vdisk and then select Provisioning
> Create Snapshots.
2. In the main panel, select each volume to take a snapshot of. To select or clear all volumes, toggle the
checkbox in the heading row.
3. Click Create Snapshots. If the task succeeds, the snapshots appear in the Configuration View panel.
