Displaying the Alarm Log of the Raid Array

Figure 44 - RAID Array Status Screen

The RAID controller keeps track of any condition that would adversely affect its reliability. In the
event that an error should occur, the alarm log will be helpful in diagnosing the problem.

The above drawing will appear.

• Select MONITOR>ALARMS from the screen.
• Make note of any error conditions reported, and what Port numbers they refer to.

Some examples of error messages are:
Drive Timeout Error – The drive failed to respond to a command from the controller within the
allotted time. This is sometimes a benign condition, but often indicates a hardware problem with
the drive.

Drive Error – The drive reported a data error. A rare isolated occurrence may be acceptable, but
probably indicates a drive failure.

Drive SMART Threshold Exceeded – The drive’s self diagnostic program is reporting an impending
drive failure. The drive should be replaced.

Remapping Bad Sector – This is a normal function of a hard drive’s self maintenance. As a drive
ages it is normal for sectors to fail, these are reassigned to a different part of the drive. Several may
occur within a very short period (seconds to a few minutes.). Multiple such errors within a few
days may indicate an impending drive failure.

Unclean Shutdown Detected – Power was lost without an orderly shutdown sequence, and the
parity information was not updated.
