September 8, 2006 Level 2 RAID Instruction Manual 17
Chapter 1 About the K2 Level 2 RAID storage
The K2 Level 2 utilizes dual FC-AL technology, allowing two loop configurations within a single chassis. Loop integrity is maintained during failures without user intervention. Each lo op and associated ci rcuits along with al l other active component s are on redundant, se par at e hot swappable modules. This impr oves se rvi ceability and increases fault tolerance by eliminating any single point of failure.

K2 Level 2 RAID features

The K2 Level 2 RAID controllers provide enhanced performance of up to 2 Gb/s transfer rates using SCSI protocol. Optical cables connect to hosts, such as to a K2 Media Server or to a Fibre Channel switch.
The Level 2 RAID supports one K2 Level 2 RAID Expansion Chassis. It does not support connection to PFC500E, PFR500E, or PFR600E RAID Expansion Chassis. Copper cables connect a K2 Level 2 RAID to the K2 Level 2 RAID Expansion Chassis.

Capacity and redundancy

The level 2 RAID contains five, ten, or fifteen half-height 3.5" Fibre Channel Arbitrated Loop (FC-AL) di sk drives . The chassi s also suppor ts one or t wo hardware RAID controllers in one 3U high rack-mountable chassis. The K2 Level 2 RAID currently uses 73GB, 146GB or 300GB drive capacit ies. Wit h 15 drives, one chassis holds up to 876GB, 1.7TB, or 3.6TB depending on the disk drive option.
The K2 Level 2 Expansion Chassis provides additional storage capacity. One K2 Level 2 Expansion Chassis can be connected to a single K2 RAID Storage Chassis comprising a single disk-array storage system with a total of 30 drives and approximately 1.7TB, 3.4TB, 7.2TB of storage depending on the disk drive option. This provides for cost effective storage expansion as requirements grow.

K2 Level 2 RAID components

The K2 Level 2 RAID components are:
• The chassis with passive midplane board
• One or two RAID controllers (K2 Level 2R) or two expansion adapters
• As many as fifteen Fibre Channel disk drives per chassis
• Two RAID chassis power suppli es (K2 Level 2 RAID) or expansion chassis powe r supplies
• One LAN card
Any unoccupied slot (RAID c ontroller, disk module, o r LAN card) has a filler module to maintain air flow and compliance with electromagnetic interference (EMI) standards.
The RAID controllers, e xpansion a dapters, disk dri ves, power supp lies, and the LAN card are hot-swappable field replaceable units (FRUs), which means you can add or replace the m while the K2 Level 2 RAID is powered up.
IMPORTANT: You must not hot swap operat ional RAID cont rollers or di sk drives without first disa bling t he targe t compo nent usi ng the Grass Valley Storage Ut ilit y.

Controller 1

Chassis

An optional second RAID controller module in the K2 Level 2 RAID, allows for continued access to the K2 Level 2 R AID if the primary RAID controller fails. Adding a second RAID controller to the same chassis is not intended to increase performance, but rather to add redundancy. Refer to the K2 Storage System Instruction Manual for detailed connection and configuration instructions.
The following figure shows the RAID Storage Chassis components. Details on each component follow the figure.

NOTE: Every K2 Level 2 RAID chassis power supp ly inc lud es a backup battery so that if electrical powe r is lost, data stor ed in cache memory will be saved. Dat a store cache is not used in the K2 Level 2 RAID, so the Battery Backup module is not used, even though it ships as part of the power supply.
The chassis is a sheet-metal hou sing that contains a passive midpl ane and chassis slots for the RAID controllers or expansion adapters, disk drives, power supplies, and the LAN card.
A RAID chassis (which houses one or two RAID controllers) has a pre-set chassis address of 0. An expansion chassis (which houses one or two expansion adapters) must have its chas sis address set to 1. This addre ss is set by a c ontrol on th e expansion adapter. Refer to your K2 Storage System Instruction Manual for information on setting the chassis address switch. See also, “Addressing requirements” on page 27.

Midplane

The midplane distribute s power and si gna ls to all the chassis compone nts . All FRUs plug directly into midplane connec tor s.
Disk modules
Each disk module consists of a Fibre Channel disk drive in a carrier assembly. If a disk drive fails, and needs replacing, you can do so while the RAID Storage Chassis is powered up. Replacement disk drives begin rebuilding immediately after being installed. (See “Removing and installing disk modules” on page 47.)
20 Level 2 RAID Instruction Manual September 8, 2006

K2 Level 2 RAID Circuit board modules

The disk drives are 3.5-inch FC-AL drives that conform to the Fibre Channel Arbitrated Loop (FC-AL) standards and support dual-port FC-AL interconnects through the two RAID controllers and their cabling.
NOTE: Once the K2 Level 2 External RAID is installed and configured, the disk modules become slot dependent. Moving disk modules between
!
physical slots will result in loss of data and the need to reconfigure the system.
K2 Level 2 RAID Circuit board modules
There are three circuit board modules used: the RAID controller module, the expansion adapter , and the LAN card. Th e RAID c ontroll er mod ule is in the prim ary RAID chassis. It manages the disk drives and provides a Fibre Channel interface to the K2 Media Server system or Fibre Channel switch fabric. The expansion adapter is in an Expansion chassis. It manages the disk drives, in conjunction with the connected RAID controller and provides a Fibre Channel interface to the primary chassis. The LAN card is in the primary RAID chassis only. It provides an Ethernet port for NetCentral monitoring, a shutdown switch, and signal connections for an uninterruptive power supply (UPS).
K2 Level 2 RAID RAID Storage Chassis circuit board modules
The K2 Level 2R includes one or two RAID controller modules. This provides redundant Fiber Channel interface ports.

NOTE: The K2 Level 2 Expansion chassis and K2 Level 2 RAID Controller chassis must be powered on and off in the proper sequence. Refer to proper power procedures in Chapter 2, “K2 Level 2 RAID Installation Information”.

Power supplies

There are two auto-ranging power supplies, power cord and standby switch. Each supply supports a fully configured K2 Level 2 External RAID and shares load currents with the othe r supply, if it is presen t. The power supplies are des igned so as to protect the disk drives if you install them while the K2 Level 2 External RAID is powered up. A disk with power-related faults will not adversely affect the operation of any other disk.

K2 Level 2 RAID Installation Information

This chapter describes information you’ll need to install the K2 RAID Storage (K2 Level 2 Expansion Chassis). Major topics are:
“Installation requirements”
“Installing a K2 Level 2 RAID Storage in an equipment rack”
“K2 Level 2 RAID Sto rage power-up and in itialization”
“K2 Level 2 RAID Storage power-down”

Installation requir ements

This section describes the following requirements:
“Site requirements” on page 25
“Controller configuration requirements” on page 26
“Addressing requirements” on page 27
“Cabling requirements” on page 30
“Binding disk modules into groups” on page 30

Site requirements

For proper K2 Level 2 Expansion Chassis operation, the installation site must conform to certain environmental specifications. These are detailed below and in
Chapter 4, K2 Level 2 RAID Technical Specifications and Operating Limits.
Power
Refer to “AC power requirements” on page 61 for AC power requirements. The values indicate eit her the values for the power cord of a K2 Level 2 Expansion Chassis with a single power supp ly, or the total values shared by the line cords of two powe r supplies in the same K2 Level 2 Expansion Chassis, with the division between the power cords and supplies at the current sharing ratio. If one of the two power suppli es fails, the remaining supply and cord must support the full load. You must use a rack mount cabinet with ac power distribution, and have main branch ac distribution that can handle these values for the number of K2 Level 2s and K2 Level 2 Expansion Chassis units that you will interconnect.
Cooling
Make sure your si te has air condition ing of the correct s ize and pla cement to mai ntain the specified ambient te mperatu re range. The air cond itio ning must be able to handle the requirements of th e K2 Level 2s and any connected K2 Level 2s as indicat ed under

Addressing requirements

There are two addresses for the K2 Level 2: the Fibre Channel Arbitrated Loop address ID (FC-AL address ID) and the chassis address.
FC-AL address ID
Each node (such as a RAID control ler) on the Fibre Channe l front-end loop must have a unique FC-AL address ID. The FC-AL protocol translates the FC-AL address ID into an 8-bit arbitrated loop physical address (ALPA). You set the RAID controller FC-AL address ID using switches, as explained later in this chapter. The K2 Level 2 does not allow an ID of zero. If your K2 Level 2 has a second, redundant RAID controller , it must be se t to a different FC-AL address ID than the primary FC.
Addressing requirements
When using redundant RAID controllers, set the FC-AL ID on the cont ro llers for all K2 Level 2 RAIDs connected as indicated in the following table.

Chassis address setting requirement
The chassis address for a K2 Level 2 primary RAID chassis is pre-set at 0 and does not need to be configured.
Each K2 Level 2 expansion chas sis must have its chassi s address set to 1, whic h is the factory-set value. This is set by the chassis a ddress swit ch, which is located on the expansion adapter. The following figure identifies the switch.

Cabling requirements

It is recommended that you use th e Fibre Channel cable s shipped with your K2 Level 2 Expansion Chassis when making connections. For cable specifications, refer to
“Cable lengths” on page 61.
Optical cables must meet the app ropriate 2-Gbit FC-AL loo p standards. You must use this type of cable to connect a host to the K2 Level 2 controller.
Copper cables must meet the appropriate standards for 2-Gbit FC-AL loops. You must use this type of cable to connect Expansion chassis.
K2 Level 2 and K2 Level 2 interconnections should maintain consistency. Tha t is, one FC loop should connect the K2 Level 2’s RAID controller 0 and the K2 Level 2’s expansion adapter 0. The other FC loop should connect the K2 Level 2’s RAID controller 1 and the K2 Level 2’s expansion adapter 1. If your K2 Level 2 does not have RAID controller 1, do not connect any cabling to the K2 Level 2’s expansion adapter 1.
Do not leave an unused (that is, dangling) cable connected to a Fibre Channel port because it may cause excess noise on the loop.
Diagnostic cables connec t K2 Level 2 and K2 Level 2 units. These ca bles are required for the communication of s tatus inform ation between chas sis, and support Net Central monitoring.
NOTE: Also refer to the K2 Storage System Instruction Manual for cabling diagrams and step-by-step instructions.

Binding disk modules into groups

After cabling a K2 Level 2 and any K2 Level 2s, you must bind disk modules into LUNs using the Storage Utility provided by Grass Valley. Refer to the K2 Storage System Instruction Ma nual for informati on on using the Storag e Utility to bind drive s.
NOTE: Make sure you allow adequate time for binding disk modules into LUNs. PFR500 and PFR600 controllers bind each LUN in turn, but take less than a minute for each LUN. PFC500 and K2 Level 2 controllers bind multiple LUNs at the same time, yet take more than an hour to bind a LUN. Large drive capacities and multiple LUNs can increase the binding time to 10 hours or more.

K2 Level 2 RAID Storage power-up and initialization

This section gives information about connecting power and powering-on the K2 Level 2 RAID Storage system.

Connecting electrical cables

For each chassis, there are two electrical cables (one for each power supply) that should be connected to separate outside power sources.
!
!
To prevent the plug from being inadvertently disconnec ted, secure the electr ical cable into the outlet by doing the following:
1. Check that the power switch on the RAID chassis and th ose on the host system are all set to OFF.
WARNING: Make sure the power cords meet lo cal safety and electr ical standards.
CAUTION: The K2 Level 2 RAID Storage system must be electrically grounded. Operating the syst em without proper grounding can damage disk drives. If the outlet you use is not grounded, make sure that a licensed electrician replaces it and installs a grounding conductor.
2. Insert the power cord into the power supply.
3. Secure the power cord with the stopper.
4. Insert the plug of the power cord into an AC outlet. Use a grounded AC outlet.

Powering-up the K2 Level 2 RAID Storage system

1. Power-up the K2 Level 2 Expansion cha ssis pri or to or at the same time as the K2 Level 2 Controller chassis.
NOTE: You must always power-up the K2 Level 2 Expans ion chassis prior to , or at the same time as, the K2 Level 2 RAID controller chassis. Failure to do so may prevent some LUNs in the expansion chassis from being recognized.
36 Level 2 RAID Instruction Manual September 8, 2006

K2 Level 2 RAID Storage power-down

Before turning on the AC power, c heck fo r loos e d isk dr ives by pushin g each disk drive.
2. Turn on power switches on both power supplies.
When turning on the power switches, confirm that the POWER GOOD LEDs (green) on all the po we r supp li es and POWER LEDs (green) on t he front panel of the RAID chassis and Expansion chassis go on. The power supply starts, and the POWER LED (green) is on while the power switches are on.
The RAID chassis performs the self-test and initialization immediately after the power is turned on. When the self-test and initialization terminate and the RAID chassis becomes ready, the READY LED of the controller stops flash ing and enters the on state.
3. Confirm that the READY LED is on, and then turn on the host system.
The chassis takes four minutes (at maximum) to start. Refer to sections in Chapter 3, “Servicing the K2 Level 2 RAID” for information
on interpreting status LED behavior.
NOTE: Refer to the K2 Storage System Instruction Manual for complete system power-up procedures.
K2 Level 2 RAID Storage power-down
NOTE: If your K2 Level 2 RAID Storage system is part of a shared storag e system, refer to the K2 Storage Syst em Instruction Manual for i nstructions on shutting down the shared storage before powering down a K2 Level 2 RAID Storage.
To power-down the K2 Level 2 RAID Storage correctly:
1. Stop all read/write activity to the K2 Level 2 RAID Storage storage system.
2. On the RAID controller chassis, turn off power switches on both power supplies.
3. On the Expansion chassis, turn off both power switches on both power supplies.
Alternatively, turn off all power switches of the RAID controller chassis and the Expansion chassis at the same time.
!
To turn on power, refer to “K2 Level 2 RAID Storage power-up and initializat ion” on
page 36.
CAUTION: You must always power down the K2 Level 2 RAID controller chassis prior to, or at the same time as the K2 Level 2 Expansion Chassis.

Battery Backup

Every K2 Level 2 RAID chassis power supply includes a backup battery so that if electrical power is lost, data stored in cache memory will be saved.
Data store cache is not used in Profile s torage syst ems, so the Bat tery Backup mod ule is not used, even though it ships as part of the power supply module.

Maintenance procedures using Storage Utility

Several maintenance procedures can be performed using the Grass Valley Storage Utility.
To perform the following tasks, refer to the K2 Storage System Instruction Manual:
• Checking RAID controller microcode version
• Loading RAID controller microcode: All models
• Identifying disk modules prior to removal
• Downloading K2 Level 2 disk drive firmware
• Disabling a K2 Level 2 RAID controller for removal
• Disabling a K2 Level 2 disk module for removal
• Configuring K2 Level 2 network and SNMP settings

Monitoring K2 Level 2 RAID status using NetCentral

You can monitor K2 Level 2 RAID Stor age systems us ing Grass Valle y’s NetCentral monitoring software. E nabled by SNMP, NetCentral can continuously monitor the storage system and send notifications if there is a problem. The SNMP agent software
September 8, 2006 Level 2 RAID Instruction Manual 39
Chapter 3 Servicing the K2 Level 2 RAID
required for NetCentral monitoring resides on the RAID storage device itself. As a result, the K2 Level 2 RAID appears in NetCentral as a standalone device rather than as a subsystem of the K2 Media Client.
Communication with NetCentral takes place over the LAN card Ethernet port. To monitor the K2 Level 2 RAID, you must connect network cabling, power on the system, then configure network and SNMP settings as described in the K2 Storage System Instruction Manual.
If you have the K2 Level 2 expansion chassis, you must connect the diagnostic cabling, as it is required for NetCentral monitoring.
Refer to the N etCentral O n-line Help for information on monitoring the K2 Level 2 RAID with NetCentral.

Removing and installing disk modules

!
Use the following instructions to replace a faulty disk module. It should be replaced while the RAID chassis is running (hot-swapped).
NOTE: Grass Valley does not support mixing disk drives of differing capacities within a RAID chassis. All disk drives in any RAID chassis must be of the same capacity. For example, if a K2 Level 2 RAID Storage and a K2 Level 2 Expansion Chassis are used, all the disk drives in both the K2 Level 2 and the K2 Level 2 Expansion Chassis must be of the same capacity.

Moving disk modules

!
CAUTION: If the RAID chassis does not have the r edundant controller option, when a replacement disk module is inserted there can be a 1.5 second (maximum) disruption of video (record/play).
CAUTION: You can destroy the media file system beyond recovery if you move a disk module to a different sl ot. The service person can move a disk module when you don’t care about losing the media in the media file system and under the following cautions:
September 8, 2006 Level 2 RAID Instruction Manual 47
Chapter 3 Servicing the K2 Level 2 RAID
• The disk module must be unbound.
• Moving a drive module that i s part of a LUN to another slot makes al l informat ion on the LUN inaccessible.
• You must remove and install the disk module while the storage system is powered up.
A disk module must be inserted all the way or removed entirely. Do not leave a disk module partially removed exce pt for periods when you are allowing it to spin down. When replacing multiple disks, observe the following:
• The RAID chassis configuration i nformation is written to the first three disk modules. If all of th ese disk modules are rep laced with new device s with the power supplies turned off, the information is lost. This condition is indicated by the SERVICE LED blinking at a high rate at chassis power up. Therefore, do not replace the first three d isk modules with the po wer supplies turned off.
• When multiple disk modules are subject to replacement, they must be replaced with new disk modules one by one. Do not replace multiple disk modules simultaneously. Afte r checking that the Ready LED on the front panel of the current disk module is lit, commence replacing the next disk module.
• Stick on the physical label indicating the installation position on each newly installed disk module.
• If both disk modules in 16 and 29 (or 17 and 30) in the expansion chassis are defective or uninstalled, the Service LED on the expansion chassis and the Fault LED on the expansion adapter will go off. In this case, first install a sound disk module in 16 or 29 (or 17 or 30). If the expansion adapter operates normally, the Service LED on the expansion chassi s and the Fault LED on the expansion adapter will go off.
!
CAUTION: Handle a disk module gently and use an ESD wristband. Do not remove a faulty disk module until you have a replacement module (with the same part number) or a filler module available.

Removing a disk module

NOTE: If a disk module has been bound into a LUN, do not mov e it to another slot unless you do not care about the data on the LUN. Each module has LUN identifying information written w hen it is bou nd. Moving it to another sl ot can make information on the original LUN inaccessible.
Generally, you should not remove a disk module unless it is faulty. Refer to
“Interpreting fr ont panel LEDs” on pa ge 41 and “Monitoring K2 Level 2 RAID status using NetCentral” on page 39.
NOTE: If you wish to remove an operational disk module, use the Grass Valley Storage Utility to disable the disk before removing it.
To remove the disk module:
1. Confir m the location of the fa ulty disk module by checking its Fault LED. A lso check NetCentral messages. NetCentral messages may report disk faults by disk

Replacing a RAID controller or expansion adapter

Use the following instructions to replace a RAID controller or expansion adapter. It should be replaced while the chassis is powered up (hot-swapped).
NOTE: Ensure that the RAID controller module you are installing has the same microcode version as the module being replaced. Otherwise, the replacement module will not initializ e. Refer to the K2 Storage S ystem Instr uction Manual for information on checking contro ller firmware versions.
NOTE: A K2 Level 2 RAID must have at least one RAID controller installed. Do not remove both RAID controllers, even in an offline condition. Since the controllers store the configuration information of the RAID chassis or the product license unlock information, replacing the two controllers simultaneously loses the data.

Removing a RAID controller or expansion adapter

To remove a RAID controller or expansion adapter:
1. Identify the module to be replaced using NetCentral or verify that the module’s Fault LED is on. If you are removing an operatio nal RAID controller, use the Grass Valley Storage Utility to disable the RAID controller.
2. Remove the cables connect ed to the module. No te wher e the c ables connect to t he module.
3. Loosen the ejector set screw.
