Before you begin to configure Charon-HPA emulator instances and to install guest systems, it is advisable to create a directory structure for storing the data required by Charon-HPA emulator instances and guest systems.
The space Space required for the guest operating systems alone:
- HP3000: a minimum of 10GB
- HP9000: a minimum of 80GB
In addition to this, you need to consider space required for applications installed on the guest systems and the data required by such applicationsThe numbers above are just basic guidelines. The space actually required, must be reviewed based on the individual configuration of the system to be migrated.
The installation examples of this user's guide may use smaller emulated disks than the ones described above. This was done to make it easier to demonstrate basic functionality. It is not a recommendation for actual system sizing.
The following shows a sample directory structure. A structure similar to this will be used for the rest of the examples in this section:
|
The LDEVS directory Disk and Tape directories will be used to store emulated logical devices, for example, disk containers.

- If the NetworkManager is not needed for other purposes, you can disable ( commandcommands: # systemctl stop NetworkManager; systemctl disable NetworkManager) and create the initial ifcfg-<interface> files in /etc/sysconfig/network-scripts/ manually.
- If the NetworkManager is required for other purposes,
- make sure it uses the ifcfg-files (plugins=ifcfg-rh must be enabled in section [main] of /etc/NetworkManager/NetworkManager.conf),
- stop the NetworkManager (command: # systemctl stop NetworkManager),
- exclude all interfaces required for the Charon-HPA guest(s) from NetworkManager control by adding the line NM_CONTROLLED=no to the respective ifcfg-<interface> file(s),
- restart the NetworkManager (command: # systemctl start NetworkManager).
