Replacing an nTier300 VTL or nTier500 Data
Drive
These instructions describe replacing a data drive in the Spectra®nTier300
Deduplication Virtual Tape Library (VTL) appliance (the nTier300 VTL) or the nTier500
Intelligent Secondary Storage appliance (the nTier500). The appliances are referred to
as the nTier300/500 in these instructions. Except where noted, the procedure for
replacing a data drive is the same for both appliances.
Note: The illustrations in these instructions show the nTier500, which can
contain from eight to sixteen data drives mounted on individual drive
sleds, depending on the configuration. The nTier300 VTL contains eight
drives. In both products, the data drives are accessed from the front of
the appliance.
If one or more drives in the nTier300/500 are not functioning properly, the Drives tab
on the Overview page of the BlueScale web interface turns red, indicating an error
condition. Although the RAID 6 volume can continue to operate with one or two
malfunctioning drives, you run the risk of data loss if a third drive fails. Replace any
malfunctioning drive(s) as soon as possible to avoid degraded performance.
Preparing for Replacement
Spectra Logic recommends that you back up your nTier300/500 configuration before
replacing a data drive. Refer to the documentation that accompanied your
nTier300/500 for information about backing up your configuration.
Estimated Time Required
Replacing a data drive takes about five minutes. This procedure can be performed
without interrupting the operation of the nTier300/500. As soon as you install the new
drive, it automatically powers on and the RAID-6 volume to which the drive belongs is
rebuilt using the parity data stored on the remaining drives in the volume.
Note: Rebuilding the RAID-6 volume may take up to 28 hours. During this time,
the throughput of data to the RAID volume is reduced until rebuild is
complete and the drives are resynchronized.
Prepare the Work Area
Ensure that the environment is free of conditions that could cause electrostatic
discharge (ESD)—If possible, use an antistatic mat and a grounded static protection
wristband during installation. If a mat and wristband are not available, touch a known
grounded surface, such as the nTier700’s metal chassis.

Preparing for Replacement

Materials and Tools
Required:
A grounded anti-static wristband
A replacement data drive
A #2 Phillips screwdriver
An anti-static bag for the malfunctioning data drive
Shipping materials for returning the malfunctioning data drive to Spectra Logic
Recommended:
An anti-static mat
Identify the Malfunctioning Drive
Note: If you are uncertain about which drive to replace, contact SpectraGuard
Support for assistance (see Contacting Spectra Logic on page 3).
Note: You can also use the operator panel on the nTier500 cover to identify a
malfunctioning drive (see Using the nT500 Operator Panel to Identify a
Malfunctioning Drive on page 9).
Use the following steps to identify the malfunctioning drive through the BlueScale web
interface.
1. Open a web browser on a computer connected to the same network as the
nTier700.
2. Log into the BlueScale web interface as described in the Spectra nTier500 User
Guide or the Spectra nTier300 VTL Installation Guide.

Using the nT500 Operator Panel to Identify a Malfunctioning Drive The operator panel on
the nTier500 cover also indicates when there is a problem with one of the drives. When
a drive is not operating correctly, a red warning symbol displays on the general status
tab (Figure 3). Selecting the Drive Status tab provides more detailed information about
the data drives, including the status and location of individual drives. If a drive needs
replacement, a red warning symbol displays for the specific drive (see Figure 4).
Remove the Front Cover
1. If the front cover is installed, insert a key into the lock on each side of the front
cover. Turn both keys until they are in the vertical position to unlock the cover
(Figure 5).
2. Carefully pull the cover straight out from the chassis to remove it. Set the cover
aside.

Replacing the Drive
The data drives are mounted on custom drive sleds that provide the mounting and
electrical connections required to operate them in the nTier300/500 chassis. Only
install drives that you purchase from Spectra Logic. For assistance, see Contacting
Spectra Logic on page 3.
Remove the Drive
Use the following steps if you need to remove a drive.
1. Put on the provided anti-static wristband and attach it to an unpainted metallic
surface. Leave the wristband on throughout the entire replacement procedure.
2. Locate the malfunctioning drive you previously identified (see Identify the
Malfunctioning Drive on page 7).
Caution
Any damage to the nTier300/500 caused by failure to protect
it from electrostatic discharge (ESD) voids the warranty. To
protect it and the data drives from damage:
Wear an anti-static wristband, properly grounded,
throughout the procedure. If a wristband is not available,
touch a known grounded surface, such as the unpainted
metal chassis. An anti-static wristband is included with the
accessories.
Leave the drive in its anti-static bag until you are ready to
install it.
Do not place the un-bagged drive on any metal surfaces.
Caution
When removing a drive while the system is powered-on, slide
the drive sled out of the chassis approximately 1 inch, just
enough to disengage the drive sled’s interface connector from
the chassis. Leave the sled in that position for approximately
20 seconds before completely removing it from the system.
This delay gives the drive’s platters time to stop spinning,
which will help avoid further potential damage that might
interfere with an accurate failure analysis.
Caution
When removing the upper right-most drive in an nTier500, be
careful not to bump the PC card extending out from the
chassis. You could damage the card or inadvertently press the
power button and inadvertently turn off the unit.

3. Slide the sled latch to the right to release it (Figure 6).
4. Open the drive sled handle by rotating it outward and toward the left to disengage
the drive sled from the chassis (Figure 7).
5. While supporting the drive sled, first slide it out of the chassis about 1 inch and
leave it in that position for approximately 20 seconds. Then, slide the sled
completely out of the chassis.
6. Place the drive on an anti-static mat so that the screws securing it to the sled are
accessible.
Install the New Drive on the Sled
1. Using a #2 Phillips screwdriver, unscrew the four screws securing the
malfunctioning drive to the drive sled (Figure 8). Remove the drive from the drive
sled and set the drive aside.

2. Remove the new drive from its anti-static bag.
3. Place the drive into the sled so that the drive connectors are positioned at the back
of the drive sled and the mounting screw holes are toward the bottom of the drive
sled (Figure 8).
4. Align mounting holes in the drive with the screw holes in the drive sled.
5. Using a #2 Phillips screwdriver, install the four mounting screws to secure the new
drive to the drive sled, as shown in Figure 8.
Install the New Drive
The drive mapping for the RAID volumes is dynamic; the drive is automatically
detected when it is installed. The system determines the current drive positions during
the first system boot and automatically updates the drive locations to preserve that
volume’s preconfigured RAID 6 volume.
Follow these steps to install the new drive:
1. Slide the latch on the drive sled the right to release it, then rotate the handle
outward and to the left (Figure 9).
o

2. With the drive handle in the open position, slide the drive sled into the chassis until
the front of the drive sled is flush against the front of the chassis. The drive sled
slides in easily; do not force it.
3. When the drive sled is in position, push the handle inward and to the right until it
locks in place. An audible click indicates that the drive sled is locked into position.
Note: The latch occasionally sticks in the open position. If this happens, simply
push it to the left and press the handle inward to lock the drive into
place.
4. As soon as the drive is seated, it powers on and the process of rebuilding the RAID
volume begins.
Note: Rebuilding an array may take hours to complete. Backups continue
uninterrupted but may be slower until the rebuild is completed.
5. Package the malfunctioning drive and ship it to Spectra Logic as described in
Returning a Malfunctioning Drive on page 27.
Caution
When installing the upper right-most drive in an nTier500, be
careful not to bump the PC card extending out from the
