To provide fault tolerance from disk errors and single disk failure, the high capacity HiveManager uses level 1
RAID (Redundant Array of Independent Drives) HDDs (hard disk drives). Each HDD holds identical data, the
data that is written to one disk being mirrored to the other. The lower LEDs on the front of each HDD flash in
unison to indicate that they are writing data to memory. The upper LEDs indicate that they have power. See
.
Figure 8 Hard disk drive LEDs
If you notice that only one of the lower LEDs is flashing while the other is dark, then there is an HDD failure.
Although the HiveManager can continue with just one operational HDD, you should replace the faulty HDD soon.
1. Turn off the HiveManager.
2. Unlock the tray door for the HDD that you want to replace.
3. Pull the tab on the left side of the door, and open the door, swivelling it on the hinge along its right side.
As you open the door, the HDD tray automatically extends.
4. Remove the failed HDD and insert a replacement
5. Close and lock the door.
6. Connect a serial cable to the console port
7. Connect one end of an RS-232 serial cable to the male DB-9 console port on the HiveManager and other
end to the serial port (or COM port) on your management system.
8. Start a serial connection by running a VT100 emulation program on your management system with the
following settings:
•
Bits per second (baud rate): 9600
•
Data bits: 8
•
Parity: none
•
Stop bits: 1
•
Flow control: none
9. Turn on the HiveManager.
10. While it is booting up, press and hold down the CTRL+A keys until the utility console appears.
11. From the main menu, select Manage Arrays. (An array is the logical representation of a physical HDD unit.)
HiveManager HDDs are not hot swappable. You must turn off the power before replacing an HDD.
The replacement disk drive must be new or, if it has been used, there must not be a root file system on
it. Also, it must be the same size as or bigger than the other disk drive.
