DD640, DD670, DD860, and DD890 Disk Drive Replacement 5
Overview
Table 1 shows the disk drive specifications for the DD640, DD670, DD860, and DD890
systems.
Note: The DD640 is available as a 7-drive or 12-drive system.
Disk drive slots are numbered top down in each column, starting at the top left as shown
in Figure 1. Unused disk drive slots contain blank carriers.
Figure 1: DD640 and DD670 Disk drive numbers
Figure 2: DD860 and DD890 Disk Drive Numbers
Note: Some Data Domain systems have less than 12 disks. All disk drive bays must
contain a carrier with a disk drive installed in it or a carrier with an air baffle installed.
The disk drive carriers contain LED indicators to display the disk drive status.

Note: If the amber LED is on (alert or fault) and the disk drive is also powered on (blue),
the combination of the two colors is light purple (fuchsia).
Preparing for Disk Drive Replacement
Caution:
Only trained and qualified personnel should install or replace this equipment.
Identify the failed disk drive
To display the disk drive hardware status, use the disk show reliability-data
command. The display is similar to the following. The first twelve entries in the display
are the twelve disk drives in the chassis (for a DD670 system or a 12-drive DD640
system):

12 drives operating normally.
Notes:
•DD860 or DD890 output shows only information about its four disk drives. A
DD640 7-drive system shows only information about its seven disk drives.
•Always replace a failed disk drive as soon as possible. A DD860 or DD890 system
can run with two live disk drives and no spare, but another disk drive failure
disables the system. A DD640 system has one hot spare and either 6 or 11 usable
disks in a RAID-6 configuration and a DD670 has one hot spare and 11 usable

disks in a RAID-6 configuration. After the first disk drive failure, the hot spare
becomes active. If a DD640 or DD670 has two failed drives and no spare is
available, the system becomes disabled.
The system assigns a disk drive state to a replacement disk drive depending on the
history of the disk drive. Use the disk show state command to display the state of all
disk drives. See Step 6 on Page 8 for sample command output.
•A Data Domain field replaceable unit disk drive is labeled as Spare.
•A disk drive that was on another system as a spare is labeled as Spare.
•A disk drive that was on another system and that contained data is seen as Foreign.
The disk unfail command moves the disk drive to the state of Spare. Be sure that
the data on the disk drive is not needed elsewhere before giving the disk unfail
command.
Disk Drive Replacement
Follow the procedures in this section to remove and replace a failed disk drive.
Remove the failed disk drive
1. If the disk drive that you want to replace is not marked as Failed in output from the
disk show state command, use the following command (with the correct disk-id)
to fail the disk drive.
# disk fail <enclosure id> <disk-id>
2. Identify the physical disk drive. The lower LED on a failed disk drive glows a steady
amber, blue, or fuschia. Amber marks the disk as failed, but a failed disk might also
show blue or fuschia. If you cannot identify the failed disk from its LED, use the
following commands to identify a disk drive by name and then flash the LED on the
disk drive:
# disk show state
# disk beacon <enclosure id> <disk-id>
Cautions:
•Whenever servicing parts in a running system, move slowly while inserting and
latching the new parts. This avoids creating strong vibrations in the chassis which
might interfere with nearby operating disk drives.
•To ensure proper airflow and cooling, all disk drive bays must contain either a
carrier with a disk drive installed in it or a carrier with an air baffle installed.
3. Slide the gray disk drive carrier ejector latch to the right to release the ejector handle.
See Figure 4.

4. Pull on the handle to slide the failed disk drive out about an inch, until it is
disengaged from the backplane.
5. Carefully remove the disk drive from the chassis.
Install the replacement disk drive
Caution: Allow a minimum of at least one minute between removal of the old disk and
insertion of the new disk.
1. Remove the replacement disk drive from the packaging and remove the disk drive
from the antistatic bag.
2. On the replacement disk drive carrier, make sure that the handle is pulled open.
3. With the disk drive carrier handle in the open position, carefully slide the disk drive
carrier all the way into the same disk drive bay location in the chassis until it stops.
4. Use the handle to push the carrier until it docks in the chassis, then close the handle.
Use care to avoid excessive force that could damage the replacement disk drive.
Note: If the disk exhibits excessive force to install, remove the disk drive from the bay
and repeat the installation. Never force-fit the drive into the chassis.
5. If the disk drive still shows as failed, enter the following command (with the correct
disk-id):
# disk unfail <enclosure id> <disk-id>
6. Use the following command to check that the system recognizes the disk drive. In the
command display, the disk drive State should be spare or the Additional Status
should be reconstructing.
Note: A DD640 7-disk system displays information for only seven drives. The DD860
and DD890 displays information for only four disk drives.
Enclosure 1 in the following display is representative of the DD640 or DD670, twelve disk
drive systems. Enclosure 2 displays information for external shelves.

7. Inform those who receive the autosupport reports that the disk drive replacement is
done.
# autosupport send
8. Return the failed or replaced disk drive to Data Domain. Reuse the packaging from
the new disk drive and use the included prepaid waybill for shipping. Reference the
RMA number on the outside of the package. Returns with no RMA number cannot be
accepted.
