4.1.2 Raid Indicators and alarms

The GalaxyNASLX2 built in SATA / SAS RAID drives have front facing green or blue drive
LEDs indicating the drive is online and in use. If a drive fails, its LED indicator turns red and
an alarm sounds.
Note: the GalaxyNASLX2 are typically setup with a RAID 6 [2 parity drives] or in
certain cases RAID 5 [1 parity drive] . This type of RAID configuration has been found
to be the safest, allowing a disk drive to fail , yet you can continue to use the
GalaxyNASLX2 while your data is safe.
The bad drive 'degrades' the RAID but doesn't stop you from using the GalaxyNASLX2. The
bad drive's LED turns red, the RAID controller alarm comes on and, if the RAID controller has
email notification setup, an email will be sent alerting of the error. If an externally attached
RAID [ Galaxy FC attached RAID] has a bad drive, the same drive indication will occur with
more details posted in the Galaxy front operator panel.
Warning: Internal and external RAIDs on the GalaxyNASLX2 do not send error
info or alerts to the GalaxyNASLX2 OS when the RAID is in this 'degraded state'.
Therefore, the GalaxyNASLX2 OS is incapable of sending an email or alert of any kind
when a non-lethal RAID problem occurs. We strongly suggest you setup email
notification for the specific RAID controller installed in your GalaxyNASLX2. This
procedure is in the attached RAID manual or call or email Rorke tech support

4.1.2.1 Raid manager / GUI Figure 4.2

Internal SATA RAIDs can be troubleshot easily by launching the RAID's GUI manager from
the "RAID/FC" menu. If the Raid GUI manager is not represented by a button on that page,
check how to launch and troubleshoot the RAID in the attached RAID card's manual.
In the case of Areca, connect the monitor and keyboard, and reboot the RAID.
Immediately hit the TAB key and you will be sent into the text command line RAID manager.
In the case of 3ware, clik the '3DM2' button on the RAID/FC and use '3ware' as the
password to view the various pulldown tabs in the windows based manager. Specific
maintenance functions of the RAID units like replacing the bad drive, replacing a RAID
controller, and other RAID maintenance functions are discussed in the maintenance section of
the specific vendors manual. The most common areas in the 3ware GUI for you to check are
the:
Summary: This area gives the overall status of the RAID units [ groups of drives made into a
group called a Logical unit number [LUN]. The Summary area gives you the LUN ID
number[0,1....] the driver its using , and its status.
Unit: When the status of the 'unit' is "error', click on the 'unit' id number to find out more about
the specific condition. The unit information will show degraded [ one of the RAID drives is bad
and needs replacing] or inoperable[ 2 or more of the RAID drives have failed and need
replacing].
