Restore an Image from a Bootable DVD
- Step 1: Create a Boot Configuration
- Step 2: Add the Image File to the Boot Configuration
- Step 3: Build the Bootable DVD
- Step 4: Boot and Image the Computer
Altiris® Deployment Solution software provides a number of tools to remotely image computers.
On occasion, you might encounter situations where you need to image a computer without network connectivity or you want the image and tools available locally.
This article outlines the process to create a bootable DVD using automation tools and a computer image. With these tools you can quickly and easily restore an image from a bootable DVD.
- Deployment Solution 6.8 or later.
- Linux automation. Instructions for installing this are in the Deployment Solution Reference Guide (Deployment Console > Help > Product Guide).
- A computer image captured using Deployment Solution to restore.
- A computer with the capability to burn an .ISO image to a DVD.
- A target computer with the capability to boot to a DVD.
Note: This process also works with CDs and USB drives, though your image size is restricted by the capacity of the device.
Create a Boot Configuration
- In Boot Disk Creator (Deployment Console > Tools > Boot Disk Creator), create a new Linux automation configuration.
- Complete the Boot Configuration Wizard, leaving Lock Keyboard unselected:
- When the Create Boot Disk screen appears, click Cancel:
You need to make some manual changes to the configuration before creating the disk.
Add the Image File to the Boot Configuration
Due to ramdisk limitations, there is a size constraint on the files that can be included in a boot image.
To get around this, Boot Disk Creator provides a mechanism to mount a folder outside of the ramdisk, letting you to use the full capacity of a boot DVD.
- Right-click your configuration and select New > Folder.
- Name this folder "." as shown in the following screen shot:
Files placed in this folder are mounted to a special mount point in Linux automation, /mnt/atrsboot. The "." name is the convention Boot Disk Creator uses to identify the files you want mounted.
- Right-click the folder you created and select Add File. Browse to your image file (.IMG) and click Open.
- Right-click the folder you created and add the Linux rdeployt executable for your platform (x86 or x64) using the same process. Adding this executable directly to the image lets you run the image restore process without accessing the network.
Note: If you have x86 and x64 versions of the Linux automation operating system installed, a red ! appears on rdeployt. This indicates that this executable supports only one architecture type (either 32- or 64-bit) and you don't have a version of this executable added for other architectures. Add the executable for the other architectures you have installed-you select which version you want to use when you create the boot DVD.
- Your image and rdeployt appear in the "." folder:
Build the Bootable DVD
After you have a configuration with the image file added to the "." folder, you can build the DVD image.
- Click File > Create Network Boot Disk. In a network boot disk, the automation agent does not attempt to connect to your Deployment Server.
- Leave Bootable ISO CD Image selected, and click Next.
- Save the file where it can be accessed by the computer with the capability to write DVDs.
- Burn the .ISO image to a DVD.
Boot and Image the Computer
- Boot the computer using the bootable DVD you created.
Note: During the boot process, the computer attempts to connect to the Deployment Share. If the attempt is unsuccessful, you receive an error 255 which can be ignored.
- After Linux automation loads, the bash prompt appears:
- Enter the following commands:
cd /mnt/atrsboot ls
- Your image file appears:
- Enter the following command to restore the image:
./rdeployt -md -f[imagename.img]
Replacing [imagename.img] with the name of your image.
- When the imaging process completes, enter the following command to shutdown the computer:
When the computer restarts it contains the image you just deployed.
