Update an App VM Group (CLI)

You can change parameters such as the number of cores assigned to each VM. You can also mount an NFS. For undeployed VM groups, you can change IP addresses and hostnames.

If you need to transmit binaries or other files that are larger than 130 MB, you can update the App VM group profile to increase the allowable file size. The maximum file size varies and is displayed at the appropriate prompt. You cannot decrease the allowable size after you have increased it. You will need to perform this change on both nodes.

For details about the information you provide when creating App VMs, see App VM Group Parameters.

  1. Log into the MCMU CLI as a primary admin, such as mcinstall.

    See Log in to the MCMU CLI.

  2. Update the parameters of an App VM group.
    % mcmu tenant -A -u 

    For example:

    % mcmu tenant -A -u
