46 TeraPac User Operation and Maintenance Guide
The Detection, Isolation, and Replacement Process
In this Chapter we will walk through the process of recovering from a drive failing in the TeraPac’s
RAID array. For the purposes of these discussions, we will assume a system configuration identical to
those discussed in Chapters 3 and 4. That is, the MaxPac contains a MegaRAID card with Channel 2
controlling the
C: internal system drive and Channel 1 controlling a TeraPac containing three drives.
1) Let’s assume that the third disk in the TeraPac (drive 10) has failed. Power-up the system and
observe the MegaRAID report the failed drive (Figure 6-1)
Figure 6-1
2) At this point, unless you’ve previously disabled it, a very annoying warning beeper will be trying
to alert you to the fact that there is a problem. However, even though a drive has failed, you
can continue to use the data on the remaining drives in the array (although it is strongly
recommended that you replace the failed drive as soon as possible).
If you do wish to keep on using the TeraPac with a failed disk, you will very quickly wish to turn
the alarm off, so press
<Ctrl><M> when prompted to do so, which will take you into the
MegaRAID utility. Once you are in this utility, use the Up/Down arrow keys to highlight the
Objects item in the Management Menu (Figure 6-2).

3) Press the <Enter> key to select this item and then use the Up/Down arrow keys to highlight the
Adapter item in the ensuing menu (Figure 6-3).
