Installing the Level 2 Storage System
Use this chapter to install the K2 Level 2 (L2) storage system.
This chapter includes the following topics:
Work through these topics sequentially to install the storage system.
Level 2 system description
The level 2 storage system has one K2 media server and one L2 RAID chassis. An Expansion chassis is optional for increased storage capacity.
K2 Media Clients and other iSCSI clients, such as NewsEdits, are connected to the GigE switch. Each client has one GigE connection for media and one GigE connection for control. The GigE switch is configured with V-LANs to keep the control/FTP traffic and the media (iSCSI) traffic separate.
The K2 Media Server has two GigE connections for media, one GigE connection for control, one GigE connection for FTP, and one Fibre Channel connection to the RAID storage. The media server hosts iSCSI interface cards for the GigE media connections and a Fibre Channel card for the RAID storage connection. The iSCSI interface cards provide a bridge between GigE iSCSI and Fibre Channel SCSI. The media server also hosts software components that allow it to function in various roles, including media file system manager, media database server, and FTP server.
The L2 RAID chassis is connected via a single Fibre Channel connection to the media server. It is also connected to the GigE control network, which is required for SNMP (NetCentral) monitoring.
The K2 configuration control point PC is connected to the GigE control network. The K2 System Configuration application runs on this PC for configuring the storage system.
Refer to Description of K2 Storage Devices for more information.

Setting up the L2 RAID chassis
Do the following to prepare the L2 RAID storage devices:
In addition, you will configure network settings, SNMP settings, and bind LUNs. These tasks are part of the K2 System Configuration application and Storage Utility procedures later in this chapter. The process of binding LUNs can take a significant amount of time—as much as eight hours—so you might want to put priority on the tasks necessary to start the LUN binding process, then catch up with other tasks while the LUNs are binding.
Also refer to K2 Level 2 RAID storage description.
Assign Fibre Channel address ID
Every RAID controller must have a unique Fibre Channel address ID that identifies the controller on the Fibre Channel fabric. To set the Fibre Channel address ID on the L2 RAID, refer to the following diagram:
Connect the L2 RAID chassis
Connect Ethernet and diagnostic cabling as shown in the following diagram. Be aware of the following cabling requirements of the level 2 storage devices:
Assign chassis address on optional Expansion chassis
Every chassis must have a chassis address. The level two RAID chassis address is fixed at 0, so no configuration is required. However, if you have a L2 RAID Expansion chassis you must set its chassis address to 1 as shown in the following illustration. Also verify that the diagnostic ID switches are in the position shown.
Power on the L2 RAID chassis
Your preparations for L2 RAID storage are now complete.
Preparing K2 Storage System clients
Any devices that function as iSCSI clients to the K2 Storage System must be prepared with the following requirements:
Additional steps that are required for NewsEdits include the following:
For more information, refer to the NewsShare Technical Reference Guide.
Additional steps that are required for K2 Media Clients include the following:
For more information refer to the K2 Media Client System Guide.
Preparing K2 Media Clients
Do the following to each K2 Media Client in preparation for its addition to the K2 Storage System:
- Install the K2 Media Client in its permanent location.
- Provide power to the K2 Media Client.
- Connect cables as follows:
Connect GigE port 1 to a control port on the K2 Ethernet switch. For a redundant connection connect GigE ports 1 and 3 to control ports on the K2 Ethernet switch.Connect GigE port 2 to a media port on the K2 Ethernet switch. For a redundant connection connect GigE ports 2 and 4 to media ports on the K2 Ethernet switch.NOTE: The connections to GigE ports 2 and 4 documented here are only valid for external storage K2 Media Clients that access shared storage on a K2 Storage System. To connect GigE ports 2 and 4 on internal storage K2 Media Clients, refer to the K2 Media Client System Guide.
- Power on the K2 Media Client and log on to Windows as Windows adminstrator, which is username administrator and password adminK2 by default. Ignore startup messages referring to a missing media storage system.
- Assign a control network IP address and configure other network settings for the K2 Media Client. Refer to the networking section later in this chapter for networking information. Ports 1 and 3 are teamed, so even if are making a connection to port 1 only, you must configure network settings for the Control Team, as follows:
- On the Windows desktop, right-click My Network Places and select Properties. The Network Connections window opens.
- Look in the Device Name column and identify the entry named TEAM : Control Team.
- Right-click the icon for this entry and select Properties. The Properties dialog box opens.
- On the General tab select Internet Protocol (TCP/IP) and click the Properties button. The Internet Protocol (TCP/IP) Properties dialog box opens.
- Configure network settings as appropriate for the control network as implemented in your facility.
- Configure SNMP properties so the trap destination points to the NetCentral server PC. Use standard Windows procedures.
- If the K2 Media Client connects to the K2 Storage System with a redundant Ethernet fabric, such as in levels 2R and 3R, install Multi-Path I/O software. Refer to the next procedure Installing Multi-Path I/O Software.
- Copy the K2 Storage System hosts file onto the K2 Media Client. Refer to the networking sections later in this chapter for information about the hosts file and networking.
Installing Multi-Path I/O Software
The following procedure is required for external storage K2 Media Clients that have both Gigabit Media ports (ports 2 and 4) connected to the iSCSI Media network. Typically, this configuration is used for redundant K2 Storage Systems, such as Level 2R and Level 3R.
The installation files for the Multi-Path I/O software are copied on to the K2 Media Client when the K2 Client software is installed.
To install Multi-Path I/O software, do the following:
- If you have not already done so, connect keyboard, monitor, and mouse to the K2 Media Client and log on to Windows.
- Stop all media access. If AppCenter is open, close it.
- Click Start | Run, type
cmd
and press Enter. The MS-DOS command prompt window opens.- From the command prompt, navigate to the C:\profile\mpio directory.
- Type the following at the command prompt:
C:\profile\mpio>gdsminstall.exe -i c:\profile\mpio gdsm.inf Root\GDSM- Press Enter. The software is installed. The command prompt window reports the following:
- Restart the K2 Media Client.
- After restart, to verify that the software is installed, on the Windows desktop right-click My Computer and select Manage. The Computer Management window opens.
- In the left pane select Device Manager.
- In the right pane open the System devices node and verify that GVG ISCSI Multi-Path Device Specific Module is listed.
Sending K2 configuration to NetCentral
As you configure the K2 Storage System, information is automatically sent to NetCentral. When NetCentral receives the information it adds devices and populates its interface with a view of the K2 Storage System.
Before you begin using the K2 System Configuration application to configure the storage system, you must set up the NetCentral system according to the following requirements:
- NetCentral installed — NetCentral server software must be installed on a NetCentral server PC. This can be the K2 configuration control point PC or another PC that has network communication with the K2 Storage System control network.
- Device providers installed — A device provider must be installed on the NetCentral server PC for each type of device in the K2 Storage System. For a level 2 storage system, the following device providers must be installed:
- Control point PC device provider — This is the Windows monitoring device provider.
- K2 Media Server device provider
- HP Gigabit Switch device provider or Cisco Gigabit Switch device provider
- K2 Media Client device provider, if any K2 Media Clients are accessing the level 2 storage system.
- Device provider for iSCSI clients, if any iSCSI clients such as NewsEdits are accessing the level 2 storage system.
- K2 Level 2 RAID storage device provider
- Grass Valley PC Monitoring software installed — This software must be installed on the K2 configuration control point PC. It includes Grass Valley SNMP agents and other WMI based components to perform process monitoring. This provides the information for some of the SNMP trap messages that must be sent to NetCentral.
- Control point PC monitored by NetCentral — The K2 configuration control point PC must be added to the NetCentral system and fully monitored by NetCentral. This especially means that its SNMP trap destination is set to send SNMP traps to the NetCentral server PC. This is critical, as a SNMP trap is used as the mechanism by which the K2 configuration information is communicated to NetCentral. Whether the control point PC and the NetCentral server PC are the same PC or are different PCs, you must still add the control point PC to NetCentral.
In addition, NetCentral automatically changes its view of the K2 Storage System whenever you use the K2 System Configuration application to do one of the following:
Refer to the NetCentral User Guide to set up the NetCentral system. After installing a device provider, you can find additional documentation about monitoring that type of device on the NetCentral Help menu.
Networking for level 2
Use the topics in this section to configure the Gigabit Ethernet (GigE) network for the level 2 storage system.
Networking requirements
Required networking strategies for a K2 Storage System are as follows:
- Three networks:
- Networks must be on separate subnets.
- The media (iSCSI) network is 100% physically separate. This separation is provided by dedicated Gigabit ports, cables, and by VLANs on a single switch or by separate switches.
- The streaming network and the control network are also physically separated by dedicated ports and cables, but the traffic can be mixed on the same VLAN or switch.
- Static IP addresses are required for the media network on K2 Storage System iSCSI devices. This includes the iSCSI clients connected to the storage, such as K2 Media Clients and NewsEdits, and the K2 Media Servers.
- Machine names (host names) assigned to each K2 device.
- Host tables (hosts files) provide name resolution for the media network on each K2 Media Client, iSCSI client, and K2 Media Server.
- IP addresses for FTP/streaming ports must have name resolution such that hostnames are appended with the “_he0” suffix. You can use host tables (as in Setting up host tables) or another mechanism to provide the name resolution. This directs the streaming traffic to the correct port. Refer to the K2 Media Client System Guide for a complete explanation.
- Only K2 Media Servers need to be on the streaming network. This is because all streaming traffic goes directly to the shared storage.
- On the K2 Media Client, the four GigE ports are configured as two teams. On external storage models, one team is for the control network and one team is for the media (iSCSI) network. Each team shares a single IP address. This provides redundancy. Do not attempt to un-team these ports.
Use the following procedures as necessary to implement your networking strategies.
NOTE: Media network (iSCSI) IP addresses and Streaming network IP addresses are assigned using the K2 System Configuration application.Networking tips
Establish a consistent convention for machine names and IP addresses. It is recommended that you embed a root name or other unique identifier for this particular K2 Storage System in the computer name. Also, a common convention for IP addresses is to use a numerical pattern or sequence in the IP addresses to indicate device-types and/or ports, as in the following example:
NOTE: This example assumes a subnet mask of 255.255.255.0Example of Level 2 names and IP addresses
Computer name Device type Streaming network addresses Control network addresses Media network addresses Comments root_server_1 Media server 192.168.101.111 192.168.100.11 192.168.99.11 — 192.168.99.12 — root_raid_1 RAID — 192.168.100.51 — — root_gige_1 GigE switch — 192.168.100.61 — — root_cppc_1 Control point PC — 192.168.100.81 — — root_client_1 iSCSI client — 192.168.100.111 192.168.99.111 root_client_2 iSCSI client — 192.168.100.121 192.168.99.121 root_client_3 iSCSI client — 192.168.100.131 192.168.99.131 root_client_4 iSCSI client — 192.168.100.141 192.168.99.141
1This IP address must resolve to hostname root_server_1_he0Setting up host tables
The hosts file is used by the network to determine the IP address of devices on the network when only a the device name (hostname) is given. The steps that follow describe how to edit the hosts file located at C:\Windows\system32\drivers\etc\hosts on Windows XP and Windows 2003 Server operating system computers. If you include the names and addresses of all the devices on the network, then you can copy the same file onto all the other K2 devices instead of editing the hosts file on each K2 device.
Add the “_he0” suffix to hostnames associated with FTP/Streaming ports. Refer to the K2 Media Client System Guide for more information.
If transferring to or from a Profile XP or Open SAN system via UIM, the hosts file must also follow UIM naming conventions for those systems. Refer to the UIM Instruction Manual.
To edit the hosts file manually:
- Open the following file using Notepad or some other text editing application:
C:\Windows\system32\drivers\etc\hosts- Enter all IP addresses with machine names. The text format is simple. First type the Ethernet IP address, then use the TAB key or Space bar to insert a few spaces. Then type the machine name.
Here is an example:192.168.99.11 root_server_1
192.168.99.12 root_server_1
192.168.100.11 root_server_1
192.168.101.11 root_server_1_he0
192.168.100.51 root_raid_1
192.168.100.61 root_gige_1
- Save the file and exit the text editor.
- Copy the new hosts file onto all the other machines. This is easier than editing the file on each machine.
Testing the control network
To test the control network use the ping command as follows:
- On the control point PC, click Start | Run. The Run dialog box opens.
- Type
cmd
and click OK. The command prompt window opens.- Type
ping
, then a space, then the name of one of your K2 Storage System devices, such as the Gigabit Ethernet switch, as in the following example:- Press Enter.
The ping command should return the IP address of the device, as in the following example:This verifies that the name of the device is being correctly resolved to the IP address, which indicates that on the Control Point PC the host table entry is correct.- Ping the other K2 Storage System devices to which you have assigned control network IP addresses.
- Go to each Windows device in the K2 Storage System and repeat this procedure. This verifies that network communication is correct to and from all devices.
Configuring the level 2 storage system
Use the topics in this section to do the initial configuration of the level 2 storage system.

Use Storage Utility to complete the configuration of the L2 RAID chassis, as explained in the following topics:
Refer to Prerequisites for initial configuration to confirm that the RAID storage is ready for configuration.
Configuring L2 RAID network and SNMP settings
Use the Storage Utility to configure the following settings for the level 2 RAID chassis:
For level 2 RAID, network and SNMP settings are set and stored on the RAID LAN card. Therefore the combined RAID storage devices, including the one or two RAID controllers and the optional Expansion chassis, is a single entity on the control network. In addition, the RAID storage device is configured by default for the SNMP community name “public”. If your site’s policies require using a different SNMP community name, contact your Grass Valley representative.
To configure these settings, do the following:
- Launch Storage Utility from the K2 System Configuration application as in the previous procedure. If the RAID chassis has two controllers, you will configure the network settings on the controller currently selected when you launch Storage Utility.
- As prompted, wait while Storage Utility gathers system information, then Storage Utility opens.
- In Storage Utility tree view, expand the node for the L2 RAID, right-click the icon for a L2 RAID controller, and select Configuration | Network Properties. The Controller Network Settings dialog box opens.
- Enter the control network IP address and other network settings.

- Click OK and OK to save settings and close.
- In Storage Utility click View | Refresh. Continue with the next procedure Binding disk modules.
Binding disk modules
Use the following procedure to bind disk modules as required for the level 2 storage system.
NOTE: Binding destroys all user data on the disks.
- In the Storage Utility main window, identify bound LUNs and unbound disks by their placement in the hierarchy of the tree view. In the following illustration, disk numbers are represented by “XX”. Refer to Identifying disks for an explanation of how disks are actually numbered in Storage Utility.
- To bind unbound disks for media storage, do the following:
NOTE: Leave Full Bind selected. Do not uncheck it.
NOTE: As an aid in identifying a disk module’s physical location, select it in the Selected Disks list, then click Identify Disks. This causes the disk drive light to flash.
- Click OK to close the Binding LUN dialog box and begin the binding process. The Progress Report dialog box opens, showing the status of the binding process.
![]()
- Close the Progress Report and repeat these steps for other unbound disks. If specified by your system design, you can bind some disks as Hot Spares, as explained in Binding Hot Spare drives. When you are done, if you did not bind any extra Hot Spares, you should have the following results:
For level two storage you should have three RAID 3 LUNs of five disks each on a RAID storage device. If you have the optional Expansion chassis, you would have an additional three RAID 3 LUNs of five disks each.NOTE: L2 RAID controllers can take several hours to bind a LUN. Make sure you initiate multiple simultaneous binding processes to reduce the overall time.NOTE: Do not proceed until all LUNs are finished binding.
- Restart the K2 Media Server.
- Continue with the next procedure Creating a new file system.
Creating a new file system

If correctly configured, it is already assigned the control network IP address, which is displayed in the window.Select the other port and click Modify. A network configuration dialog box opens. Enter the media network IP address and the subnet mask.Click Next. Database Client ConfigurationThis page connects the K2 Media Client as a media database client to the K2 Media Server taking the role of media database server. If there are redundant K2 Media Servers, both are listed on this page as database servers.
Verify that the K2 Media Client is connecting to the correct K2 Media Server or Servers, as follows:• For Level 1, the client connects to the L1 RAID storage device.• For Level 2, the client connects to the only server.• For Level 2R, the client connects to server A as database server 1 and sever B as database server 2.• For Level 3, the client connects to server 1.• For Level 3R, the client connects to server 1A as database server 1 and sever 1B as database server 2.If there are multiple FTP servers, the K2 System Configuration application automatically assigns the K2 Media Client to a FTP server to provide optimum FTP bandwidth across the system.Click Check. When the wizard reports that the configuration check is successful, click Next. File System Client ConfigurationThis page connects the K2 Media Client as a media file system client to the K2 Media Server taking the role of media file system server. If there are redundant K2 Media Servers, both are listed on this page as file system servers.
Verify that the K2 Media Client is connecting to the correct K2 Media Server or Servers, as follows:• For Level 1, the client connects to the L1 RAID storage device.• For Level 2, the client connects to the only server.• For Level 2R, the client connects to server A as file system server 1 and server B as file system server 2.• For Level 3, the client connects to server 1.• For Level 3R, the client connects to server 1A as file system server 1 and server 1B as file system server 2.Click Check. When the wizard reports that the configuration check is successful, click Next. iSCSI Initiator ConfigurationThis page load balances the K2 Media Client’s iSCSI connection to the K2 Storage System. The iSCSI adapters on your K2 Media Server or servers are listed here as iSCSI targets. The K2 System Configuration application determines the iSCSI target to which each K2 Media Client subscribes, based on the bandwidth values that you enter. This enforces policies by which each K2 Media Client has sufficient bandwidth for its intended use and no individual iSCSI target is oversubscribed.
Click Modify. The Bandwidth Input dialog box opens.Enter the channel count, bit rate, and track count per channel information according to your intended use of the K2 Media Client.Click Calculate and verify that the total bandwidth is correct according to the system design for your shared storage system. You should be configuring your highest bandwidth K2 Media Clients first, to ensure that they are distributed equally across iSCSI targets. To verify this, while you are on this page for your first K2 Media Client, you can temporarily enter information and calculate the bandwidth for each of your K2 Media Clients and compare bandwidth values.Click Assign Portal, then OK to confirm.If you have a redundant K2 Storage System, the K2 System Configuration application makes the appropriate assignment to the redundant server, as reported in the Secondary target box.Click Next. Completing the Configuration Wizard Click Finish. The K2 Media Client restarts and the wizard closes.- Repeat this procedure for each of your K2 Media Clients.
