Enable Auto-Rebuild
A faulted drive is automatically replaced if Auto-
Rebuild is enabled and a suitable unallocated disk is
available. Suitable unallocated drives are initialized,
large enough to replace the degraded drive, and
cannot contain any RAID group information. The
unallocated drive may be a pre-existing drive or a
newly-seated drive.
If a Hot Spare Pool exists, the SAS/SATA RAID
storage controller chooses a suitable Hot Spare drive
before selecting an unallocated drive.
Refer to
Change RAID group properties on page 23.
Manually replace a drive
You may replace a drive and rebuild a RAID group
manually.
1 After following the Preliminary Steps on page
18, double-click on the degraded RAID group in
the bottom panel.
2 A RAID group members tab displays in the
bottom panel. Select an unallocated drive from
the drive inventory and drag it over the
degraded drive in the members tab.
If the selected drive is appropriate, the faulted
drive is replaced.
Setup RAID Notification
The ATTO ConfigTool provides a mechanism to issue a notification when a RAID event occurs in ExpressSAS
RAID or ThunderStream SC storage controllers.
RAID events are divided into three categories:
• Critical events indicate a serious problem
has occurred and the administrator of the
RAID group should perform corrective
action.
• Warning events are less serious but still
warrant notification.
• Information alerts provide additional useful
information about warnings or critical events.
The Notifications tab provides numerous drop-down
boxes that allow for the selection of the types of RAID
events to receive for a notification. There are four
options available in these drop-down boxes:
• Critical: Only RAID events of a Critical level
are reported for the notification.
• Warning: Only RAID events of Warning and
Critical level are reported for the notification.
• All: All RAID events (Information, Warning,
Critical) are reported for the notification.
• None: No RAID events are reported for the
notification. This level is particularly useful if
a notification feature is not desired.
The notifications are specified at the host system level
and apply to all ATTO SAS/SATA RAID storage
controllers installed in the host system.
Basic alerts
The Basic Alerts section of the Notifications tab
provides the controls to select the levels of RAID
events for Audible and Visual notifications, as well as
the level of RAID events to output to the system event
log.
Audible Alerts utilize the system speaker and/or the
hardware buzzer on a R6xx adapter to produce the
notification. When triggered, the alarm continuously
sounds until it is stopped by the user. There is an icon
in the system tray (or system status area) that is
used to turn off the alarm. The user must right-click on
the icon and then select
Mute Audible Alert from the
menu. This will stop the alarm. The system tray icon
also provides a control that will allow the user to
enable/disable the hardware buzzer, so that only the
alert via the system speaker is used. This allows the
hardware buzzer to be turned off independently of the
system speaker. It can also serve a remote purpose. If
the daemon is on a server in a server room, the
sysadmin can click the control to disable it. The
hardware buzzer is enabled by default.
Note
Audible alerts may not be available on your
operating system.

Visual Alert utilize pop-up message boxes to display
the contents of a RAID event. The pop-up may be
closed using the pop-ups button.
