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 efcient. 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 conguration. 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 congured and ready to use. These commands are available should you wish to

recongure the RAID.

Note: Dedicated Micros supplies the RAID pre congured 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 ofine 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 congure the RAID syslog interface to send UDP messages.

Note: The unit still needs to be congured to record video data. This procedure is performed on

the DVR, refer to ‘Conguration’.

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 modied to

incorporate fewer disks (ie ‘make 0 raid6 0.8-0.14) to allow sufcient spare disks.

Type ‘spare 0.15 to add a spare to the pool. Repeat the command for drive 16 to have two spare

drives.

TO CONFIGURE THE SYSLOG INTERFACE ON THE RAID FOR SENDING UDP MESSAGE

RAID

Conguring the Unit

The unit should be congured using the connected DVR.

Accessing the conguration page on the DVR

1. The RAID is congured using the AOE setup page on the DVR. Open the DVR

conguration pages and navigate to Record Settings->AOE setup. The AoE Setup page

allows conguration of the units ATA over Ethernet (AoE) function.

RAID

AoE

This menu allows conguration 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

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 cong 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

conguration.

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 conguration once; future calls to syslog will use the stored

information.

● Given the p ag, syslog prints the syslog conguration set with c.

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 unspecied, 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

congurations. By default, the rst interface (ether0) is used.

Conguration 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

Conguring 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

Conguration 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 congurable. Without an argument, ifstat

lists all system interfaces. The interface specication 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 specied interface. Without an argument, cecon lists all

interfaces for which CEC is served. The interface specication 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 specied interface. The interface specication is of the form

ether[09].

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 conguration 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

RAID

SR shelf 1> show s

1.1 normal

1.2 normal

1.3 normal

SR shelf 1>

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 notied 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 specied,

all current LUNs are listed. Each line output lists the LUN, size, and state. A LUNs’s state is

either online or ofine, 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.

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.

Example:

SR shelf 1> list

SR shelf 1>

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 sufciently 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

raid1 A mirrored raid device

raid5 A roundrobin parity raid device

raid6rs A double fault tolerant round robin parity raid device using ReedSolomon

syndromes

RAID

raid10 A stripe of mirrors raid device

raw A raw export of an underlying device

grow

usage: grow lun raidtype shelf.slot ...

The grow command adds a RAID to an existing LUN. The command syntax is identical to that of the

make command. Once added to LUN, a RAID may not be removed. Storage associated with LUN

can only be reclaimed by removing the entire LUN with the remove command.

Example:

SR shelf 1> list l

spare

usage: spare [ shelf.slot ... ]

The spare command lists and manages the spare device pool. For each device listed, spare

attempts to recruit the device as a spare. If the device is already in use, an error will occur. Without

arguments, spare lists all devices in the spare pool.

Example:

SR shelf 1> spare 1.01

SR shelf 1> spare

1.0 500.108GB

1.1 500.108GB

SR shelf 1>

3.3.10. rmspare

usage: rmspare shelf.slot ...

The rmspare command removes devices from the spare pool. One or more devices may be

specied as

arguments.

Example:

SR shelf 1> spare

1.0 500.108GB

1.1 500.108GB

SR shelf 1> rmspare 1.0

SR shelf 1> spare

1.1 500.108GB
