Monitoring Faults of Physical Devices
The Universal RAID Utility can take the following measures to monitor failures of Physical Devices detected by RAID
Controllers.
RAID Viewer
raidcmd
RAID Log Buzzer OS Log Alert
Depending on type of
RAID Controller
If a Physical Device used for a Logical Drive is failed, the status of the Physical Device changes to [Failed].
In addition, the status of the Logical Drive using the Physical Device changes to [Degraded] or [Offline] depending on
the redundancy. The status of the Physical Device and Logical Drive remains unchanged until the problem is solved.
If the Physical Device (SSD) used as CacheCade fails, the status of the Physical Device (SSD)
changes to Fail and the capacity of the SSD Cache Drive that includes the Physical Device
(SSD) decreases.
SSD Cache Drive operates as Read Cache of HDD. Therefore, if the status of any one of the
Physical Devices (SSD) is “Online”, the status of the SSD Cache Drive is “Online”.
The RAID
Viewer indicates the status of Physical Devices and Logical Drives with their icons on the Tree View and their
properties. In addition, the RAID Viewer shows the status from the viewpoint of the RAID System and from the viewpoint
of the server on the Tree View.
The raidcmd indicates the status of Physical Devices and Logical Drives on their properties.
The display of the RAID Viewer depending on the change of Physical
Device status is described below.
