Alarms, Errors, and Other Events
3ware provides several levels of detail about alarms, errors, and other events.
This information is available through the 3DM2 web application and the CLI.
On Windows systems, the WinAVAlarm alert utility can also be used to notify
you of events.
The next few pages describe these capabilities.
• “Viewing Alarms, Errors, and Other Events” on page 141
• “Using the Alert Utility Under Windows” on page 142
• “Downloading an Error Log” on page 144
• “Viewing SMART Data About a Drive” on page 144
CLI capabilities are described in the 3ware SATA+SAS RAID Controller Card
CLI Guide, Version 10.2.
Viewing Alarms, Errors, and Other Events
The Alarms page in 3DM2 shows a log of all events (also called
Asynchronous Event Notifications, or AENs) that have occurred on units.
These events include alarms that occur when the 3ware RAID controller
requires attention, such as when a disk unit becomes degraded and is no
longer fault tolerant. They also include SMART notifications and
informational notification, such as when sectors have been repaired during
verification.
Event messages are categorized into the following levels of severity:
• Errors (high severity events), shown next to a red box
• Warnings , shown next to a yellow box
• Information, shown next to a blue box
Examples of event messages:
• Error : Unclean shutdown
• Warning: Degraded unit
• Information : Start and completion of rebuilding, verifying, initializing,
migrating, and so forth.
3DM2 can e-mail notifications of these events to one or more recipients. For
more information, see “Managing E-mail Event Notification” on page 59.
Tip: If you have a supported enclosure, the LEDs on your enclosure may also
provide you with status information about drives. For more information, see
“Enclosure Drive LED Status Indicators” on page 136.
