How to Use OSIM › Upgrade Considerations › Update Boot Images

Update Boot Images

You must update the existing boot images with the new template files so as to be completely compatible with the new release of CA ITCM. The template files initialize the OS installation process on target computers. You can update the boot images either from the command line or using the wizard. You can choose to use the command line if you are updating multiple boot images using a batch script.

Note: If you have deployed the same boot or OS images on multiple boot servers, update the image and create a corresponding update SD package on the Image Prepare System first. You can then deploy the updated SD package to all the other boot servers in the domain using a software delivery job.

Important! DOS boot images are not FIPS-compliant and hence do not work in the FIPS-only mode.

To update a boot image from the command line

1. (Optional) Verify that you have merged the custom changes, if any, to the new template files.
2. Execute one of the following commands depending on the boot OS type:

   For WinPE20, WinPE30, WinPE20x64, or WinPE30x64

   CreateBTImages -i <image name> -e
   

   For WinPE and WinPEx64

   CreateBTImages -i <image name> -c <winpepath> [-w <ospath>] -e 
   

   The command updates the existing image with the new template.

3. Execute the following command to register the boot image:

   RegisterBTImages -i <image name> -s <manager> -e -b 
   

   The command updates boot image data in the MDB.

4. Execute the following command to update the parameter definitions of the image:

   RegisterBTImages -i <image name> -s <manager> [-v <new version no>] -e -l
   

   The command creates an SD package for the updated boot image and updates the boot image on the boot server. The updated package has "-update" appended to the original package name. You can stage the updated package on remote boot servers using an OS installation job.

   The boot image is now updated and is registered with the domain manager along with the updated SD package.

To update a boot image using the wizard

1. (Optional) Verify that you have merged the custom changes, if any, to the new template files.
2. Navigate to Software, Boot and OS Image Library, Image Prepare System, Update Boot Image in the DSM Explorer.

   The Update Boot Image wizard appears.

3. Follow the instructions in the wizard to update the boot image.

   The boot image is updated and registered with the domain manager along with the updated SD package.
