Introduction
About the…
16 Bay RAID ?
This RAID is block storage just like a hard disk drive, but located on the network. The Dedicated
Micros DVR automatically discovers AoE storage LUNs connected on the same LAN. Discovery is
performed periodically by the software driver.
AOE - is ATA over Ethernet - the same underlying protocol used to talk natively to an internal disc
drive is used as the mechanism to talk to a remote ethernet connected device. Thus the connection
can rely on the same inbuilt mechanism used by locally connected discs - but over an ethernet
transport. AOE is a low command over head protocol so is very efcient. AOE connection is at MAC
level which is a unique number for every ethernet device.
Most hubs and switches do not forward AOE packets past the local subnet so inherently the server
is secure from the outside world. AoE is not a connection based protocol. This allows the DVR
to ood Ethernet frames to all available ports on the host as storage AoE is tolerant of dropped
packets. Each packet is uniquely tagged and all packets are acknowledged. This allows AoE to
provide automatic fault tolerance without any user conguration. If the NIC or Ethernet cable or
switch goes down, packets are ooded to other used ports so storage I/O is always present.
The sixteen SATA disk slots plus RAID in a 3U shelf with redundant hot swap power modules, hot
swap fans with two Gigabit Ethernet connections, provides networked storage capacity of up to
32TB (unformatted) when used with 2TB disk drives.
This RAID6 unit is equipped with a Universal Power Supply (115-230VAC, 50/60Hz) that has two
IEC power cord connections.
Unit is shipped with standard cabinet mount slide out rails. Rails are designed to t in the cabinets
with the depth of 28” to 33”.

RAID
Setting up the RAID
1) Remove the unit from the protective packaging and mount it in its nal position.
Dedicated Micros recommends the RAID is mounted in a suitable rack for security and
safety. The unit is very heavy (over 10kg), Dedicated Micros recommends that two
people lift and position the unit.
2) Remove the Hard Drives, supplied in caddies, from the protective packaging and t into
consecutive slots in the unit, starting at position zero (top left when facing the front of
the RAID).
3) Connect a keyboard and monitor to the RAID, via the available connections on the rear
of the unit, refer to ‘Rear Panel Connections’ (keyboard and monitor are only required
during setup, but provide a useful monitoring facility).
4) Power the unit up, using the power button on the front panel. The unit should arrive
fully congured and ready to use. These commands are available should you wish to
recongure the RAID.
Note: Dedicated Micros supplies the RAID pre congured with the RAID split into 2 * RAID 6
RAIDS with one hot spare shared by the two RAIDs, this is deemed the most appropriate
storage setting a compromise between over all storage, resilience and speed.
5) Once the unit has booted and there is a command prompt available on the monitor,
type ‘cecon’.
Note: Type ‘help’ for a full list of available commands, refer to Appendix A for a selection.
6) Type ‘shelf 0’ to identify the AOE device by a number (0 - 65534).
7) Type ‘show -l‘ to show all tted drives, and the drive status.
8) Type ‘make 0 raid6 0.0-0.7’ make shelf 0 into a raid6 using drives 0 to 7. DM
recommends using RAID6 for stability and redundancy.
9) Type ‘make 0 raid6 0.8-0.16’ make shelf 0 into a raid6 using drives 8 to 16, refer to
IMPORTANT NOTE below.
10) Type ‘when’ to display the estimated completion time, or type ‘list -l’ to show the
progress of the procedure.
Note: The RAID is currently ofine until the procedure is complete. This can take up to 7 hours.
11) Once the RAID is assembled, type ‘online’ to make the RAID available across the
network.
12) Type ‘smartenable 0.0-0.16‘ to enable smart data on all drives.
13) Type ‘syslog -c‘ to congure the RAID syslog interface to send UDP messages.
Note: The unit still needs to be congured to record video data. This procedure is performed on
the DVR, refer to ‘Conguration’.
IMPORTANT NOTE
A drive can be set up as a spare to protect against loss of data if a drive fails. The RAID is not
intelligent and will go into a fail mode if a disk fails. A drive set as a spare will be introduced and
used if one should fail.
A spare disk cannot be part of an existing RAID. The second make command should be modied to
incorporate fewer disks (ie ‘make 0 raid6 0.8-0.14) to allow sufcient spare disks.
Type ‘spare 0.15 to add a spare to the pool. Repeat the command for drive 16 to have two spare
drives.

Conguring the Unit
The unit should be congured using the connected DVR.
Accessing the conguration page on the DVR
1. The RAID is congured using the AOE setup page on the DVR. Open the DVR
conguration pages and navigate to Record Settings->AOE setup. The AoE Setup page
allows conguration of the units ATA over Ethernet (AoE) function.
Dedicated Micros ©2011

RAID
AoE
This menu allows conguration of the units ATA over Ethernet (AoE) function. AoE is a network
protocol designed for simple high-performance access of storage devices over Ethernet networks.
Importantly the external storage device must be located on the same network as the unit. AoE does
not rely on network layers such as IP and TCP, making it non routable i.e. routers cannot be used
to forward a packet across disparate networks. AoE packets can only travel within a single local
Ethernet storage area network (adds a physical layer of security to the information). The stored
video can only be accessed by plugging directly into an ethernet socket in the same LAN as the
host. This means AoE cannot be accessed over the Internet or other IP networks, but makes AoE
more lightweight (with less load on the host), easier to implement, provides a layer of inherent
security, and offers higher performance. Individual modules in a single RAID can be utilised by
separate DVRs in the same subnet, each module can be used by one DVR.
Logical Devices Connected AOE Devices - Any devices in this panel are being
used by the unit to store data. These can be freed by clicking on
the Release button.
Physical Devices Available AOE Devices - Any devices in this panel are available
on
the network. They can be added to the storage capability of this
unit by ‘claiming’ the storage, using the ‘Claim’ button. Unavailable
storage is listed as Owned. Claimed storage capacity requires
formatting before it can be used.
init cong string This button will remove failed or powered down devices that had
previously been recognised and are no longer available.
FDISK This button will format the whole device, erasing all data previously
available on it and setting it up for video data storage.

RAID
Refresh (Purple) Refreshes the current page.
Adding the RAID
The RAID should be displayed in the Physical Devices panel on this page. If it is not visible, make
sure that the RAID is in the same LAN as the DVR.
1) The drive on the RAID must be ‘claimed’ before it can be formatted for use and utilised
by the DVR. Select and claim a drive that is not owned by another user. Once the drive
is claimed it will appear in the Logical Devices panel at the top of the page.
2) Claimed drives can be formatted using the FDISK button. This erases any data
previously on the sector and readies the drive to record video data.
3) Once the drive is claimed and formatted it is ready for use by the DVR. Click the
Refresh (purple) button to ensure the drive is claimed and ready and then exit the
menu. The DVR will record to this drive.

Appendix A - Available Commands
help
usage: help [ cmd ]
The help command prints the list of user commands to the console. Specifying a cmd argument
displays the usage for the named command.
sos
usage: sos
The sos command prints diagnostic information to send to CORAID support. The output contains
the SR release, model, sata card rev, disk information (model/serial/rmware), and LUN/raid
conguration.
Providing the output of this command when rst contacting support will often result in the fastest
solution to a problem.
passwd
usage: passwd
The passwd command sets the console login password. If the administrator should lose the
password given to the appliance, entering the reserved password ivelostit will begin a challenge/
response dialog which the administrator must contact CORAID support to complete. After
successfully passing the challenge/response dialog, the password will be cleared.
release
usage: release
The release command prints the release date of the currently running rmware.
Example:
SR shelf 1> release
20080304 Tue
Mar 4 15:46:52 EST 2008
SR shelf 1>
shelf
usage: shelf [ shelfno ]
The shelf command sets the shelf address of the appliance. The argument to shelf should be a
value between 0 and 65534, inclusive. It is recommended that the administrator ensure each shelf
address is unique among all AoE storage devices attached to the network. Without an argument, the
shelf address is printed.
Example:
SR shelf 1> shelf 2
SR shelf 2> shelf 2
SR shelf 2>
syslog
usage: syslog [ cp ] [ s severity ] message
The syslog command sends syslog messages to a remote syslog host at UDP port 514.
● Given the c ag, syslog enters a dialogue for the administrator to specify the source and
destination IP used in the syslog datagram, as well as the SR local interface to use when
sending syslog messages. The destination IP should be set to the desired syslog host. The
administrator need only set this conguration once; future calls to syslog will use the stored
information.
● Given the p ag, syslog prints the syslog conguration set with c.
Dedicated Micros ©2011
14
RAID
● The s ag requires an integer argument and sets the syslog severity for this message only.
If unset, the source IP address used in the syslog UDP datagram is 205.185.197.30. The syslog
facility used is local0 (16) and if unspecied, the severity is informational (6). The SR generates
messages using the default severity.
Syslog messages are only sent out one interface to avoid duplication in certain network
congurations. By default, the rst interface (ether0) is used.
Conguration of the syslog host is beyond the scope of this document.
Syslog always prints its message to the console.
Example:
SR shelf 1> syslog c
Conguring syslog. Enter IP addresses in dotted notation.
Local interface is in the format ether[09].
IPv4 destination address []: 192.168.0.1
IPv4 source address [205.185.197.30]: 192.168.0.30
Local syslog interface [ether0]: ether1
Conguration successful.
SR shelf 1> syslog p
destination IP: 192.168.0.1
source IP: 192.168.0.30
local interface: ether1
SR shelf 1>
ifstat
usage: ifstat [ a ] [ interface ... ]
The ifstat command displays the status of the Ethernet interfaces. The Ethernet address, link speed,
and capable MTU are reported. The Ethernet MTU is not congurable. Without an argument, ifstat
lists all system interfaces. The interface specication is of the form ether[09].
The a ag displays verbose statistics about the interface(s).
Example:
SR shelf 1> ifstat
name addr link (Mbps) mtu
ether0 00304833f674 1000/ 1000 9014
ether1 00304833f675 1000/ 1000 9014
ether2 0060dd4752e6 0/10000 9000
SR shelf 1>
cecon
usage: cecon [ interface ]
The cecon command enables CEC for a specied interface. Without an argument, cecon lists all
interfaces for which CEC is served. The interface specication is of the form ether[09].
Example:
SR shelf 1> cecon ether1
SR shelf 1> cecon
/net/ether1
SR shelf 1>
cecoff
usage: cecoff interface
The cecoff command disables CEC on a specied interface. The interface specication is of the form
ether[09].
Dedicated Micros ©2011

RAID
Example:
SR shelf 1> cecon
/net/ether1
SR shelf 1> cecoff ether1
SR shelf 1> cecon
SR shelf 1>
exit
usage: exit
The exit command exits the command line interface. If a password has been set with the passwd
command, the login prompt is issued.
reboot
usage: reboot
The reboot command cleanly shuts down all LUNs and their component RAIDs and reboots the
system.
halt
usage: halt
The halt command cleanly shuts down all LUNs and their component RAIDs and halts the system.
After the system is halted pressing enter reboots the unit.
sigcheck
usage: sigcheck [ ls signature ]
The sigcheck command lists and sets the signature on the SR boot ash. A signature is unique to
the SR boot ash for which it is generated.
● The l ag displays the signature details. The output of sigcheck l can be provided to CORAID
support in order to obtain a ash signature.
● The s ag accepts a signature parameter and directs sigcheck to validate the signature. If the
signature is valid, sigcheck stores the signature on the SR boot ash for future use.
show
usage: show [ lcms ]
The show command displays information about the disks in the appliance.
● The l ag shows extended information about each disk, including its size and state. Valid
disk states are missing, initing, up, and connectfail. If the connectfail disk state is listed, the
SR has given up trying to initialize the disk. This state is typically only entered when a disk is
misbehaving; the SR stops communicating with the disk to conserve system resources. The
user must use the resetdisk command to manually reset the disk and retry initialization.
● The m ag reports the SATA connection mode; valid states are sata1, sata2, or missing. SATA
connection modes are determined by autonegotiation and are not controllable. It is common for
disks in an SR to be in a mixed sata1/sata2 state, even for identical disk models.
● The s ag reports the SMART status; valid states are normal, threshhold exceeded, disabled,
and unknown. The unknown condition is provided when a disk is missing or SMART
communication is unsuccessful.
● The c ag shows raid conguration information sometimes needed by CORAID support.
Example:
SR shelf 1> show l
1.0 82.35GB up
1.1 82.35GB up
1.2 82.35GB up
1.3 82.35GB up

smartenable
usage: smartenable shelf.slot ...
The smartenable command enables the SMART command feature set on a drive. SMART must
be enabled in order for the SMART status to be obtainable with show s.
This state is maintained by the disk and is persistent across power cycle.
smartdisable
usage: smartdisable shelf.slot ...
The smartdisable command disables the SMART command feature set on a drive. This is
primarily useful when the administrator no longer wants to be notied about a disk that has
exceeded an error threshhold.
resetdisk
usage: resetdisk shelf.slot ...
The resetdisk command manually resets the SATA connection to one or more disk slots. It is
only useful when a disk has entered into the connectfail state.
list
usage: list [ l ] [ lun ... ]
The list command shows the LUNs currently exported by the appliance. If a lun is not specied,
all current LUNs are listed. Each line output lists the LUN, size, and state. A LUNs’s state is
either online or ofine, indicating whether or not it is accepting requests.
● The l (the letter “l”) ag gives detailed information about the LUN’s components. The rst
line in each record displays the LUN, size, and state of the LUN. The next indention level
displays component RAID parts and their size, type, state, and during parity initialization/
reconstruction, percentage completion.
Dedicated Micros ©2011

RAID
The state of the component RAID is one or more of:
initing RAID is initializing parity.
recovering RAID is rebuilding replaced component.
degraded RAID is operating with failed or missing components.
failed RAID has sustained too many component failures and is unusable.
normal RAID is operating normally.
Following the RAID component at the next indention level are the drive components in the RAID,
one per line. Each line displays the drive’s RAID component address, state, size, and physical shelf.
slot location.
The state of the drive component is one of:
failed drive has failed.
replaced drive is being used as a replacement for a failed drive.
missing a placeholder for a missing drive; possible if all components are not available at
startup time.
normal drive is operating normally.

make
usage: make lun raidtype [ shelf.slot ... ]
The make command creates RAIDs and initializes them to a LUN. The LUN eld must be a value
between 0 and 63, inclusive. If set sufciently high the LUN may not be addressible from the client
system. CORAID recommends administrators verify LUN addressibility with host system drivers prior
to allocation.
The raidtype eld may be one of:
raidL A linear raid device
raid0 A striped raid device
