Checking Unit and Drive Status through 3DM

www.3ware.com
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. On Windows systems, the WinAVAlarm utility monitors the controller
and will display a message window and give an audible alarm when events
occur at or above the threshold you select for it.
Details about these features are described in this section, which is organized
into the following topics:
• Checking Unit and Drive Status through 3DM
• Viewing a List of Drives
• Enclosure Drive LED Status Indicators
• Unit Statuses
• Drive Statuses
• About Degraded Units
• About Inoperable Units
• Locating a Drive by Blinking Its LED
• Alarms, Errors, and Other Events
• Background Tasks
• Scheduling Background Tasks
The information screens in 3DM let you see both summary and detailed
information about your 3ware RAID controller, configured units, and
available drives. 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).
