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 2 (3DM2) provide tools to let you check unit
and drive status, and manually start background maintenance tasks.
3DM2 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 3DM2
• 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
Checking Unit and Drive Status through 3DM2
The information screens in 3DM2 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.
Mac User Note: The 3ware BIOS Manager (3BM) tool is not available for Mac OS
X users. Mac users need to use the 3DM2 tool.
