Using the 3ware Disk ManagerĀ® 139
UM-MV-86-B1-0801 Cybernetics
This is useful if you know that a drive is developing a problem and you want to replace it,
or to replace a drive which has already failed. 
1. In 3DM, choose 
Management > Maintenance.
Remove Drive links appear next to all drives that can be removed from units, and next
to drives in the Available Drives list.
2. Locate the drive you want to remove and click the 
Remove Drive link.
(You can remove a drive that is part of a unit, or that is shown in the list of Available
Drives.)
3. When 3DM asks you to confirm that you want to remove the drive, click 
OK.
Caution 
If you unplug a drive without first removing it through 3DM, Rescan will 
not recognize it as gone. Always use the Remove Drive command to 
remove a drive before unplugging it.
