46 Broadcast Time Delay
Replacing a Hard Drive
Generally, the only time that a hard drive should be removed from the disk array is when the drive
array diagnostic software identifies a permanent fault. In this case, the front panel DRIVES
DRIVES DRIVES DRIVES LED will
blink. Use the hard disk management tools to verify that a drive is at fault. The application
monitors many things about the array and individual drives, and will clearly indicate whether a
drive has failed.
Each hard drive bay is numbered 0 through 3, as are the drives. If for any reason one or more
drives have been removed, they must be reinstalled in a bay whose number matches the drive.
Installation in the wrong location will damage data stored on all drives.
1. Turn system power OFF with the front panel button. After it has shut down, turn off the AC
power switch and unplug the AC power cord.
2. Remove the front panel as described above.
3. Unscrew the holding plate from the front of the drive sub-chassis.
4. Disconnect the power and Serial ATA data cable from the drive, and remove it from the
drive bay.
5. Replace the drive, fasten the holding plate in place, and reattach drive cables. Note that
the data cables are numbered; re-attach then to the same drive location from which they
were removed.
6. Replace the front panel and tighten the two large screws.
7. Replace the AC power cord and turn on the rear panel AC switch.
8. Turn the system ON using the front panel button and check the RAID array status.
9. Check for correct operation of the server.
NOTE: All drives in the RAID array should be identical. Any replacement must have an actual
capacity equal to or larger than the drives that existed when the array was originally created.
Drives that are advertised as being a particular size vary in actual size. Before attempting to
rebuild an array check that the size of the drive reported when it is installed is at least equal to or
larger than the existing drives in the array. See the size columns shown in figure 26 and 27.
