Rescanning the Controller Figure 69. Result of Removing Drive from Unit in 3DM Rescanning the Controller When you make a change by physically adding or removing drives or units, you can have 3DM rescan the controller to update the list of units and available drives shown on the Maintenance page. For more information, see "Adding a Drive through 3DM" on page 168. This is useful in a variety of circumstances. For example, if you added new drives to the controller, you can make them available by rescanning the controller. Rescanning checks all ports on the controller. It then updates the status of all ports, 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 Reference section, under "Maintenance Page" on page 100. www.3ware.com 171
