Array Information:
Displayed are the Serial number of the selected enclosure, the volume name (once the drive has been parti-
tioned) and the connection type.
Configuration and Selected Configuration:
Normally the Configuration and Selected Configuration should match. “Configuration” is the current disk ar-
ray configuration, as it was last set. “Selected configuration” is the new configuration that it’s being changed
to, which is set using the Change Configuration utility. These would be mismatched if you are in the process
of changing from one drive mode to another, such as changing from RAID 0 to RAID 1. If these are mis-
matched, you can set them to match in one of 2 ways:
1. Answer yes to initialize the disk question when Glyph Manager first detects the newly selected ar-
ray. This changes to the “Selected configuration”.
2. Use Glyph Manager to change “Selected configuration” to match “Configuration”. This keeps the
current configuration.
Fan Speed:
The Glyph Manager software controls the enclosure’s internal fan rpm, and it is normal for it to vary. It is pos-
sible at times for the software to turn the fan off, so a speed of 0 is also a normal condition. The fan speed
display is used in helping to diagnose problems relating to excessive temperatures.
Temperature:
Individual drive temperatures are monitored, as well as the temperature of the “bridge” (the internal circuits).
Drive temperatures over 68 C is detrimental to continued proper operation of the drives.
Status:
Indicates array functionality. A properly functioning array condition is “Fully operational”. Other states are:
“Initialized”, “Degraded operation” and “Halted”. “Degraded operation” means that a drive has failed. Due to
the redundant nature of a RAID 1 array no data has been lost and operation can continue. However, the fail-
ure of another drive will result in data loss. The failed drive should be replaced as soon as possible. “Halted”
means that the RAID array cannot continue operation due to drive failure and that data has been lost. A
drive failure is catastrophic when the array is configured as either Spanning or RAID 0. A loss of a single drive
will result in the loss of all data.
LED behavior relating to Glyph Manager:
Any error that results in the system state “Halted” generates a solid red LED on the front panel of the drive.
All other errors - including RAID state mismatch - result in the blinking red LED. All errors will animate the
Glyph ball in the dock under OS X or generate an error balloon under Windows.
NOTE: It is normal for the LED to flash red when the unit is powered on. Since the drives inside the GT 062E
take a few seconds to spin up, they are “offline” for a moment when the controller looks for them, and the red
warning LED comes on. When they fully spin up the controller sees that everything is normal, and turns the
red LED off.
