Mirrored Array
Maintenance

From the 3DM Configure Display (see Figure 56), you can desig-
nate an available drive as a hot spare, schedule rebuilds and media
scans, or remove and add a drive as part of a hot swap procedure.
To access the Configure Display, enter the URL of the 3DM port in
the address bar of your standard web browser. You must be con-
nected to the same network as 3DM. The default URL is http://
localhost:1080/ or 127.0.0.1: 1080. Navigate to the Configure dis-
play. The display shows all drives attached to each 3ware controller.
