RAID problems
• Faulty HDDs should be replaced as soon as possible
as a further HDD failure may result in loss of data.
• The Media RAID HDD is a hot-swappable item.
When the unit is use, do not remove more than one
HDD at a time as removal of a second HDD may
result in loss of data.
Failure or degraded operation of the Media RAID or the
OS RAID may be alerted to an operator in various ways:
• Errors reported on the Diagnostics page of the
Administration web page utility.
• Red LED present on the affected Media RAID drive (to
be visible, the Front Bezel must be removed).
• Performance degradation (frame dropping or slow server
response).
• Failure or degraded operation alert is broadcast to a
nominated client machine using Windows Messenger
(see
HDXC-C030 HDXC-B030 HDXC-X030 HDXC-
L030 Installation Manual for instructions on setting up
this facility).
