• Have an installed Photon Management Daemon on the client.
• Have in installed Photon Management Daemon CLI (pmd-cli) on a machine from which you perform the updates.

Procedure

1. To initiate remote update, log in to a machine that has Photon Management Daemon CLI installed over SSH.

2. Identify packages that can be updated on the client machine.

   • List the available updates for the machine.

pmd-cli --server-name <machine-IP-address> --user root pkg list updates

3. Verify the currently installed version of a package, for example sed.

pmd-cli --server-name <machine-IP-address> --user root pkg installed sed

The installed version number shows as earlier than the one listed under the available updates.

4. Initiate the update, in this example of the sed package, enter password, and wait for the command to complete.

pmd-cli --server-name <machine-IP-address> --user root pkg update sed

5. (Optional) Verify that the client machine package was updated successfully.
