Update OS Images

How to Use OSIM › Upgrade Considerations › Update OS Images

Update OS Images

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

Note: If the domain manager is operating in the FIPS‑only mode, deployment of Windows 2000 operating system using OSIM is not supported as it requires a DOS boot image; DOS boot images are not FIPS-compliant.

To update an OS image from the command line

(Optional) Verify that you have merged the custom changes, if any, to the new template files.
Execute the following command:
```
CreatOSImage -i <imagename> -e
```
The command updates the existing image with the new template.
Do the following to include additional device drivers to the OS image:
1. Copy the new or updated device driver files to the OS image store.
  The OS image is updated with the device driver files that needs to be deployed when installing the OS.
2. Edit the <image store>\<image name>\osinfo.ini file of the image and specify the list of files you want to add or delete in the [update] section.
  This step helps ensure that the additional files are deployed on the target systems.
Execute the following command to update the OS image on the domain manager:
```
registerOSImage -i <image name> -s <manager> -e  
```
The command updates the image on the domain manager specified with the -s parameter.
Execute the following command if you need an SD package for updating the OS image on a remote boot server:
```
registerOSImage -i <image name> -s <manager> -e -l 
```
The command creates an SD package with the updated OS image. The updated package has "-update" appended to the original package name. The updated package can be used to update the OS image on remote boot servers using an SD job with the "upgrade" procedure.
Execute the following command to update the parameter definitions of the image:
Important! You may lose the customized parameter definitions if they have been updated or deleted in the new template.
```
registerOSImage -i <image name> -s <manager> -e -b
```
The command updates the parameter definitions of the OS image in the MDB. The updates include changes to the default values, new, updated, or deleted parameter definitions.

The OS image is now updated in the domain manager and in the boot servers.

To update an OS image using the wizard

(Optional) Verify that you have merged the custom changes, if any, to the new template files.
Navigate to Software, Boot and OS Image Library, Image Prepare System, Update OS Image in the DSM Explorer.
The Update OS Image wizard appears.
Follow the instructions in the wizard to update the OS image.
The OS image is updated and registered with the domain manager based on the options you have selected. You must now deploy the updated SD package on the other boot servers that stage the OS image that you just updated.
