Maintaining Units
3ware RAID controllers include a number of features in the firmware that
help maintain the integrity of your drives, check for errors, repair bad sectors,
and rebuild units when drives degrade. In addition, 3ware BIOS Manager
(3BM) and 3ware Disk Manager (3DM) provide tools to let you check unit
and drive status, and manually start background maintenance tasks. 3DM also
lets you review alarms and errors and schedule background maintenance
tasks.
This section includes the following tasks to help you maintain your units:
„

Checking Unit and Drive Status through
3DM
The information screens in 3DM let you see both summary and detailed
information about your 3ware RAID controller, configured units, and
available drives in 3DM. You can quickly see the status of your controller and
drives, and drill down to find details about any units or drives that have
problems.
A status column on the controller, unit, and drive information pages lets you
quickly see whether everything is working (OK), performing a task (such as
initializing, verifying, or rebuilding), or has a problem (error, degraded,
warning).
