Rescanning the Controller
When you make a change by physically adding or removing drives or units, you can have 3DM2 rescan the controller to update the list of units and available drives shown on the Maintenance page.
This is useful in a variety of circumstances. For example, if you add new drives to the controller, you can make them available by rescanning the controller. Or if you turn on an enclosure after turning on your computer, you can use rescan to make the controller see the drives.
Rescanning checks all ports on the controller. It then updates the status of all attached disks, so if error conditions have been fixed, the status is updated to reflect that. For more details about how the Rescan feature works, see the information in the 3DM2 Reference section, under Maintenance page.
To rescan the controller

1 | In 3DM2, choose Management >> Maintenance.

2 | On the Maintenance page, click Rescan Controller.

3DM2 scans the controller for information about units and drives, and updates the information shown on the Maintenance page.
