Drives
Each MegaDrive chassis can house up to six 9-GB drives (the standard
is four or Þve). Drives 1 through 4 contain media data, drive 5 is a
parity drive, and the auxiliary drive is an unpowered optional spare.
The drives are numbered as shown in Figure 11-10.
Figure 11-10 MegaDrive Configuration
The drives can be locked into place. You must unlock a drive before
you can remove it from the MegaDrive chassis. The lock above drive 5
unlocks the drive controller (see Figure 11-8).
There are two LEDs on the front panel of each drive. The top LED
indicates the status of the drive. When the LED is green, the drive is
active and operating normally. If the LED is red, the drive has spun
down. Either the drive is about to spin up, or it has failed. When a
drive fails, an alarm sounds.
The lower LED on the front panel of each drive indicates activity on
the drive. This LED glows green when the drive is being read from or
written to.
