Flow
• New Transmitter Services
• Inbuilt proxy DHCP Service
• PXE server that offers boot image to endpoint
• Inbuilt TFTP service
• Offers boot image over tftp service
• Endpoint starts
• Client sends DHCP-request (IP and PXE-details)
• ”Regular” DHCP-server responds with IP
• Transmitter responds with PXE-details (boot-menu)
• Client presents boot-menu
• Client discovers boot-servers
• Transmitter responds, providing a client-specific boot-file etc
• Client downloads boot-file over TFTP
• Transmitter TFTP-server serves the boot-file and following files
• Client launches pre-boot OS (WinPE)
• WinPE comes with custom script that download appropriate channels (info) and go ahead with disk partition and OS installation
Preparation
Copyright © 2013 Symphony Teleca Corp. All rights reserved. CONFIDENTIAL AND PROPRIETARY 10
Preparation
• Channels needed
– OS image (s) for OS/Arch – http://products.marimba.com/Win7Image
• Content rep channel for OS Image (Wim)
– Migration profile - http://products.marimba.com/SalesProfile
• Content rep channel that contains detail about OS Image, credentials etc (created through UI)
– Profile Info channel - http://products.marimba.com/Info
• Content rep channel that contains file ‘mapping.txt’
• Should contain mapping of mac ids and profile to be used. E.g.
– 00:0c:29:41:e8:a6=http://products.marimba.com/SalesProfile
Copyright © 2013 Symphony Teleca Corp. All rights reserved. CONFIDENTIAL AND PROPRIETARY 11
Preparation
• Channels needed
– Boot image specific to OS/Arch/Custom definition
• Prepare boot image using WAIK (UI available in marimba)
• Special properties
– type=BootImage [this type channels are loaded in tx as potential boot image for requests]
– bootfile=pxelinux.0 [points to the boot loader file (set implicit by UI)]
– boot.arch=0 [Sets the architecture; this will be mapped to architecture mapping for specific/all endpoints. In a general note, you can use 0 for x86, 1 for x64, 2 for x86_embedded and so on]. There must be 1 boot file per architecture. You cant have multiple boot channels with same arch property.
• WinPE image to have config.txt (inside windows/system32) and should have two properties
– Channel.url (channel url for info channel)
– Install.type=baremetal (to notify that it is in baremetal cycle and so it should ignore migration steps)
DHCP & PXE/TFTP on different boxes

Preparation
• Transmitter settings
– Set transmitter property ‘osd.services.enabled=true’ to activate pxe and tftp services in transmitter
– Set transmitter property ‘osd.pxe.disable=false’ to enable pxe service, with this both tftp & PXE will start
– Set transmitter property ‘osd.mtftp.group’. This should be the multicast group that the server would use to monitor UDP requests during DHCP/PXE phase
– Set transmitter property ‘osd.macdefinition.path’ and point to the path of file that contains mac mapping (whether mac is activated for OS migration and what boot file it should pick). E.g.
<?xml version="1.0" encoding="UTF-8" ?>
<hosts>
<host mac="abcd" activation="true" bootindex="0"><host/>
<host mac="efgh" activation="true" bootindex="1"><host/>
<host mac="general" activation="true" bootindex="0"><host/>
</hosts>
– Set transmitter property ‘osd.macdefinition.sync.interval’ to set sync interval of activation file
– Set transmitter property ‘osd.all.activated’ if you want to activate all machines by default
– Set transmitter property ‘osd.boot.timeout’ if you want to set timeout; default is 5 seconds
– Set transmitter property ‘osd.boot.prompt’ if you want to set boot prompt; default is “Booting from Marimbma Transmitter. Press <F8> for menu.”

Preparation
• Transmitter and endpoints must have bridged network (can talk to each other over transmitter http bind address). To force transmitter to bind itself to specific adapter set property ‘transmitter.http.bindAddress’
DHCP & TFTP on same box

Preparation
• Transmitter settings
– Set transmitter property ‘osd.services.enabled=true’ to activate pxe and tftp services in transmitter
– Set transmitter property ‘osd.pxe.disable=true’ to disable pxe service, Only tftp will start on tx
– Set transmitter property ‘osd.mtftp.group’. This should be the multicast group that the server would use to monitor UDP requests during DHCP/PXE phase
– Set transmitter property ‘osd.macdefinition.path’ and point to the path of file that contains mac mapping (whether mac is activated for OS migration and what boot file it should pick). E.g.
<?xml version="1.0" encoding="UTF-8" ?>
<hosts>
<host mac="abcd" activation="true" bootindex="0"><host/>
<host mac="efgh" activation="true" bootindex="1"><host/>
<host mac="general" activation="true" bootindex="0"><host/>
</hosts>
– Set transmitter property ‘osd.macdefinition.sync.interval’ to set sync interval of activation file
– Set transmitter property ‘osd.all.activated’ if you want to activate all machines by default
– Set transmitter property ‘osd.boot.timeout’ if you want to set timeout; default is 5 seconds
– Set transmitter property ‘osd.boot.prompt’ if you want to set boot prompt; default is “Booting from Marimbma Transmitter. Press <F8> for menu.”

Preparation
• Transmitter and endpoints must have bridged network (can talk to each other over transmitter http bind address). To force transmitter to bind itself to specific adapter set property ‘transmitter.http.bindAddress’
• DHCP Configuration required
– Set option 66 to point to same machine server name / IP address (localhost/hostname/ipaddress)
– Set option 67 to point to boot file (pxelinux.0)
• Make sure you disable pxe by setting transmitter property ‘osd.pxe.disable’
Workflow
Copyright © 2013 Symphony Teleca Corp. All rights reserved. CONFIDENTIAL AND PROPRIETARY 21
• No change required in DHCP server
• Transmitter running pxe/tftp (port should be opened and there shouldn’t be other pxe in multicast group)
• Transmitter must have all channels and settings (explained earlier)
• Endpoint must be configured to boot from network (PXE boot)
• Endpoint completes DHCP request-offer cycle with regulalr DHCP
• Endpoint connects to transmitter for PXE cycle and gets boot image (loader) info
• Endpoint boots into winPE (winPE), loads config.txt to locate info channel url
• Endpoint downloads info channel to get details about profile (for mac)
• Endpoint downloads the profile channel to get all details like OS image url, Credentials etc
• Endpoint prepares the machine (partitioning etc), downloads the image, apply that, change boot sequence and gets into OS installation
Workflow
In progress items
Copyright © 2013 Symphony Teleca Corp. All rights reserved. CONFIDENTIAL AND PROPRIETARY 23
• Boot image management – UI workflow needs some work
• Automating preparatory channels (like info)
• Automating activation/deactivation of machines*

Open issues
2. Debug messages without debug flags…
3. VBScript change to handle boot sequence – bug there but there is a workaround so this will be low defect
