3DM2 is the current version of the 3ware Disk Manager. Throughout this
documentation, it is referred to interchangeably as 3DM and 3DM2.
• 3ware Alert Utility (WinAVAlarm)
The 3ware Alert Utility for Windows runs on the system in which the
3ware RAID controller is installed and provides direct notification by a
pop-up message and audio alarm when events occur. You can configure
this unit to specify the type of events that should generate these
notifications. For details, see “Using the Alert Utility Under Windows” on
page 142.
• 3ware CLI (Command Line Interface)
The 3ware CLI provides the functionality available in 3DM2 through a
command line interface. CLI also provides advanced functions not
included in 3DM2 such as, drive performance monitoring (DPM). You
can view unit status and version information and perform maintenance
functions such as adding or removing drives, and reconfiguring RAID
units online. You also can use it to remotely administer controllers in a
system.
The 3ware CLI is described in 3ware SATA+SAS RAID Controller Card
CLI Guide, Version 10.2 and in the 3ware HTML Bookshelf.
Monitoring, Maintenance, and
Troubleshooting Features
Several 3ware RAID controller features aid in monitoring and
troubleshooting your drives.
• Auto-Rebuild. When you do not have a spare available, setting the Auto
Rebuild policy allows rebuilds to occur with an available drive or with a
failed drive. (For more information, see “Setting the Auto-Rebuild
Policy” on page 71.)
• Drive Performance Monitoring (DPM). DPM is an advanced trouble-
shooting tool used to measure drive performance, and to help identify
when a specific drive is causing problems so that you can repair or replace
it. Commands are available through the 3ware CLI to enable and disable
DPM, and to see a range of different statistics. These statistics can be
useful to help troubleshoot problems with your RAID controller and
units. For more information, see “Drive Performance Monitoring” on
page 229.
• Enclosure Services. Drives, fans, temperature sensors, and power
supplies in supported chassis and enclosures can be identified by flashing
LEDs so that you can quickly identify which component needs to be
checked or replaced. For more information, see “Enclosure Management”
on page 179.
