Introduction
Audible Alarm
Adaptec RAID controllers are equipped with an audible alarm that
alerts you to situations that affect safety of your data. This section
discusses the following topics:
■
■
For additional details on how to control the alarm, see
and the Adaptec Storage Manager online Help.
Sounding the Alarm
The alarm sounds under the following circumstances:
■
When the controller is running, the alarm sounds when a drive
fails. For example, if a drive becomes unplugged, the alarm
sounds.
■
When restarting the system, the alarm sounds if an array is
degraded. For example, if a drive is missing from a three-drive
RAID 5, the alarms sounds.
■
If an array can’t be configured, the alarm sounds. For example,
if a drive is missing from a RAID 0, or if two drives are missing
from a RAID-5, the alarm sounds.
Silencing the Alarm
The alarm continues to sound until one of the following actions is
taken:
■
The array with the failed member is deleted.
■
If the array is redundant, a rebuild begins.
■
The alarm is silenced using SATASelect or SCSISelect. For
details, see the Alarm Control option on
or Adaptec
Storage Manager online Help.
Automatic Failover
Adaptec RAID controllers can automatically rebuild an array when
a failed drive is replaced with a new drive. This feature applies
only to redundant arrays in SES- or SAF-TE-enabled drive
enclosures. See
for details.
