9. Expanding RAID Storage Capacity
Note: Mac OS X cannot support partition expansion – DO NOT attempt to use the WebGUI’s OCE or ORLM
functions with a Mac system.
To Expand RAID storage capacity:
a. Back up all original data to a separate storage device.
b. Delete the current RAID array
c. Create a new array using the original and added disks.
d. Restore the data from the backup source to the new array.
10. NA762TB Audible Alarm
The NA762TB has two internal Alarm buzzers. These two Alarm buzzers will emit different types of
sound when an error condition is detected.
10.1 Storage controller buzzer:
This buzzer is for HDD failure (offline) status notification and it will emit a high pitch continuous
sound. This alarm will sound when a disk failure occurs or a disk or an array is removed without using
the “unplug” feature in the WebGUI. When the sound is triggered, follow the steps below to check
the HDD status and mute the alarm.
a. Open the WebGUI and switch to the logical tab. The alarm can be stopped using the
WebGUI’s Mute button, or the Rescan function found under the Physical or Logical tabs.
b. Check the physical device status if there are any disabled drives.
c. Locate the disk module number. The NA762TB’s HDD status LED will emit a solid red light if a
disk has failed. Check the HDD status LED and locate the failed disk.
d. If the RAID is in critical status, please follow “Chapter 8 RAID Disk Failure Recovery” to
recover the RAID disk
e. For other RAID status, please refer p.37 for RAID recovery
10.2 Enclosure buzzer
The alarm buzzer will emit an intermittent sound when a cooling fan has failed, or the enclosure is
overheating. Follow the steps below to check the enclosure status and mute the alarm.
a. Use the mute button on the front panel of NA762TB to mute the alarm.
b. Check if the FAN and Temperature LED from the front panel of NA762TB is light on red.
c. If the enclosure alarm actives, this is usually related to NA762TB hardware problem. Please
contact Technical Support and report the issue.
