## How to Perform an Initial Installation (Command Line)

The initial installation must be initiated from each managed host to be installed.

1. Ensure that the managed hosts you want to install have been added to the Change Manager server.

   See How to Add Managed Hosts (Command Line).

2. Determine which managed hosts you want to install.

   For example, install the `/web-server/host1` and `/web-server/host2` managed hosts.

3. Modify the shared profiles and host properties to reflect the configuration of the managed hosts.

   - To configure the managed hosts for reinstallation operations, configure one boot environment.

   - To configure the managed hosts for updates, configure two boot environments.

4. Set up the files for installation.

       $ changemgr setup [ -u username ] [ -p file ] [ -d domain ] \
       topopath ...

   topopath

     Specifies the path to a managed host or host group. The managed host or host group is relative to the top of the specified administrative domain.

   For descriptions of the other options, see How to Add Managed Hosts (Command Line).

   Caution –

   If you modify the associated shared profile or host properties before you perform the initial installation, you must re-create the JumpStart profiles. To re-create the JumpStart profiles, rerun `changemgr setup`. Then type `boot net - install` at the OpenBoot prompt.

5. Go to the console of each of the managed hosts to be installed and do the following:

   1. Bring each managed host to the `ok>` prompt.

      If the managed host is running, press Stop-A.

   2. On each console, type `boot net `-` install` and press Return.

      Be sure to include the space between the `-` and `install`.

      Caution –

      Make sure that the managed host is only a network boot client of the Change Manager server.

      The network boot of your managed host might fail with an error message such as `Panic: unable to mount file systems`. If such a message appears, then your managed host is probably being served by more than one network boot server. See `Panic: unable to mount file systems` Message Appears While Booting From the Network.
