Maintenance Page
The Maintenance page appears when you choose Management > Maintenance from
the menu bar. The Maintenance page lets you perform maintenance tasks on existing
units on the current controller (shown in the drop-down list on the menu bar), and lets you
create new units by configuring available drives.
Rescan Controller
Use the Rescan Controller button to have 3DM scan the available drives in the controller
and update the list of available drives shown. This is useful in a variety of maintenance
tasks. For example, if you physically plug in a drive and want the controller to recognize
the newly plugged in drive.
Rescan checks empty ports for newly plugged in drives. If those drives were previously
part of a 3ware RAID configuration and they still have valid DCB (Disk Configuration
Block) information on them, the controller tries to piece them back together into a working
unit. If a working unit can be formed, it will appear in the Unit Maintenance list when the
scan is complete.
This process is known as importing drives.If new drives do not have any data indicating
they were previously part of a 3ware RAID configuration, they will appear in the Available
Drives list.
