Drive Replacement
(using a redundant RAID mode such as RAID 1, 5, or 6 with auto-shutdown enabled)
This section describes the process of replacing a hard drive while the TeraStation is off. To replace the failed hard drive:
1
Before replacing the hard drive, update your rmware to the latest
version.
2
Open the front cover with the included key.
3
Push the cartridge tab of the failed hard drive (denoted by the
glowing red Status LED) to the left and swing the lock around to the
left.
4
Pull out the hard drive cartridge and remove it from the TeraStation.
5
Insert the OP-HD series hard drive (sold separately) into the empty
slot from Step 4.
6
Slide the drive into the TeraStation, then swing the lock back down
until it clicks into place.
7
Press the power button on the TeraStation to turn it on.
Drive Replacement
(RAID 0 or Normal Mode)
If the TeraStation is set to RAID 0 or Normal mode, hard drives do not automatically turn o in the event of a malfunction. The Status LED will be ashing red.
Before replacing the hard drive, either dismount the drive from within the TeraStation's Web Admin interface, or shut down the TeraStation. This section describes
the process of hard drive replacement while the TeraStation is still on.
1
Click [System] - [Storage] in the TeraStation's Web Admin interface.
2
3
The Status LED will stop ashing and glow steadily.
4
Open the front cover with the included key.
5
Push the cartridge tab of the failed hard drive (denoted by the
glowing red Status LED) to the left and swing the lock around to the
left.
Hard drives without red Status LEDs lit are still on. Do not unplug
or remove them. If you do so, data may be lost or the TeraStation
may malfunction.
6
Pull out the hard drive cartridge and remove it from the TeraStation.
7
Insert the OP-HD series hard drive (sold separately) into the empty
slot from Step 6.
8
Slide the drive into the TeraStation, then swing the lock back down
until it clicks into place.
Drive Replacement
(using a redundant RAID mode such as RAID 1, 5, or 6 with a hot spare configured)
If your TeraStation's drives are in a redundant RAID mode, and you have a hot spare enabled, a malfunctioning drive in the array is replaced by the spare disk and
the RAID array is rebuilt automatically. The Status LED will continue to glow red for the failed drive even after the RAID array is rebuilt with the hot spare. This
section describes the replacement process for a hard drive while the TeraStation is still on.
To replace the failed hard drive:
1
Open the front cover with the included key.
2
Push the cartridge tab of the failed hard drive (denoted by the
glowing red Status LED) to the left and swing the lock around to the
left.
Hard drives without red Status LEDs lit are still on. Do not unplug
or remove them. If you do so, data may be lost or the TeraStation
may malfunction.
3
Pull out the hard drive cartridge and remove it from the TeraStation.
4
Insert the OP-HD series hard drive (sold separately) into the empty
slot from Step 3.
5
Slide the drive into the TeraStation, then swing the lock back down
until it clicks into place.
Replacing a non-malfunctioning hard drive
Do not replace a hard drive which is not malfunctioning (unless it has been converted to a media cartridge).
If you must change a drive that is not malfunctioning, either dismount it in the TeraStation's Web Admin interface or shut down the TeraStation before replacing the drive. Then rebuild the RAID
array if you are in a redundant RAID mode such as RAID 1, 5, or 6. If you are using RAID 0, delete the RAID array. If you are using normal mode, format the hard drive.
・ If you are using a redundant RAID mode such as RAID 1, 5, or 6, the RAID array will be in degraded mode after performing this operation. You will not be able to use the TeraStation until you
rebuild the RAID array.
・ If you are operating in RAID 0 mode, all data on that RAID array will be deleted after performing this procedure. You will not be able to use the TeraStation until you reformat the hard drive.
・ If you are operating in Normal Mode, all data on that hard drive will be deleted after performing this procedure. You will not be able to use the TeraStation until you reformat the hard drive.
・ If you remove more than one drive at the same time, all data on the RAID array will be lost regardless of which RAID mode the TeraStation is in. To preserve your data, replace drives one at a
time, rebuilding the RAID array after each replacement.
Hard Drive Replacement Examples
(1) Select the hard drive with
the flashing Status LED.
(2) Click [Remove Disk].
8
When the replacement hard drive is recognized, the Status LED will flash and
the front LCD panel of the TeraStation will display the message, "Press
FuncSW I31 New Diskx ready."
9
Hold down the Function button on the front of the TeraStation for 3 seconds
until it beeps. The TeraStation will start rebuilding the RAID array
automatically.
It takes about 5 minutes before the message "RAID I18 ARRAYx Rebuilding" is
displayed.
All data on the newly installed OP-HD series hard drive will be erased during
this process.
You have now completed the hard drive replacement process.
9
For RAID 0
When the replacement hard drive is recognized, the Status LED will flash and
the front LCD panel of the TeraStation will display the message, "Set from Web
I32 New Diskx ready."
Select [System] - [Storage] - [RAID Array] in the TeraStation's Web Admin
interface and click [Delete RAID Array].
Select the replacement hard drive by navigating to [System] - [Storage] - [Disks]
and click [Format Disk] to format the new drive. Configure RAID mode by
selecting [System] - [Storage] - [RAID Array] after formatting the hard drive.
If a hard drive malfunctions in RAID 0, all data on the RAID array will be lost. All
of the settings for the shared folders (such as access restrictions) will be erased
after replacing a drive from a RAID 0 array.
For Normal Mode
When the replacement hard drive is recognized, the Status LED will flash and
the front LCD panel of the TeraStation will display the message, "Press FuncSW
I31 New Diskx ready."
Hold down the Function button on the front of the TeraStation for 3 seconds
until it beeps. The hard drive will be formatted automatically and the drive will
be ready to use as a normal disk.
All data on the newly installed OP-HD series hard drive will be erased during
this process.
You have now completed the hard drive replacement process.
6
When the replacement hard drive is recognized, the Status LED will flash and
the front LCD panel of the TeraStation will display the message, "Press
FuncSW I31 New Diskx ready."
7
Hold down the Function button on the front of the TeraStation for 3 seconds
until it beeps. The replacement hard drive is automatically registered as a hot
spare.
To use the replacement disk as a normal drive rather than a hot spare, navigate
to [System] - [Storage] - [RAID Array] in the TeraStation's Web Admin interface,
select the new drive, and click [Set to normal disk].
All data on the newly installed OP-HD series hard drive will be erased during
this process.
You have now completed the hard drive replacement process.
