Please note that before stopping CHARON-AXP, a clean shutdown of the operating system running on the virtual machine has to be performed.

Warning
The total number of devices (both controllers and units, including disks) displayed by CHARON SRM console is limited to 48. Note that it does not affect the actual number of configured devices provided to CHARON guest OS.

Copy the sample script "/opt/charon/bin/charon.service" ( "/opt/charon/bin/charon" for Red Hat Linux 6.x) to the "/usr/lib/systemd/system/" directory (or to your home directory for Red Hat Enterprise Linux 6.x).

Example:

Red Hat Linux 6.x	`$ cp /opt/charon/bin/charon /my_services/es40_service` `$ chmod 755 /my_services/es40_service`
Red Hat Enterprise Linux 7.x and /CentOS 7 .x& 8	`$ cp /opt/charon/bin/charon.service /usr/lib/systemd/system/es40.service` `$ chmod 755 /usr/lib/systemd/system/es40.service`

Edit the renamed file to replace sample values of the following parameters.

Example:

Red Hat Linux 6.x	`exec="/opt/charon/bin/es40"` `prog="my_es40"` `config="/my_services/es40-service.cfg"`
Red Hat Enterprise Linux 7.x and /CentOS 7 .x& 8	`ExecStart=/opt/charon/bin/es40 -d /my_services/es40-service.cfg` `WorkingDirectory=/my_services`

"my_es40" is a service name in the example above

Create and edit the configuration file ( "/my_services/es40-service.cfg" in the examples above) the way it was described before and make sure the following pre-requisites are met:

OPA0 must be configured as a virtual port or physical console, not as an operator console.
Example:
set COM1 alias=OPA0 port=10003
#set COM1 alias = OPA0 line = (console)

Use only absolute paths to log, toy clock, nvram files and all the other data such as disk images, etc. The names of the references files must be unique.

Example:

...

set session log="/CharonInstances/1st_es40.log" set rom container="/CharonInstances/1st_es40.bin" set toy container="/CharonInstances/1st_es40.dat"

set PKA container[0]="/CharonInstances/1st_es40_boot_disk.vdisk"

...

Make sure the same physical devices are not used by other CHARON-AXP daemons and the OPA0 console port number is unique across the CHARON server.

...

Red Hat Linux 6.x	`# ln -sf /my_services/es40_service /etc/init.d/es40_service` `# chkconfig es40_service on` `# service es40_service start`
Red Hat Enterprise Linux 7.x and /CentOS 7 .x& 8	`# systemctl enable es40.service` `# systemctl start es40.service`

Info

title	Red Hat Enterprise Linux 7.x and /CentOS 7 .x& 8

If you update the /usr/lib/systemd/system/<my virtual machine>.service file, the following command must be executed in order to take changes into account:

# systemctl daemon-reload

...

Red Hat Linux 6.x	`# service es40_service stop`
Red Hat Enterprise Linux 7.x and /CentOS 7 .x& 8	`# systemctl stop es40`

Please note that before stopping a CHARON-AXP service, a clean shutdown of the operating system running on the virtual machine has to be performed.

...

Red Hat Linux 6.x	`# chkconfig es40_service off` `# chkconfig --del es40_service` `# rm -f /etc/init.d/es40_service`
Red Hat Enterprise Linux 7.x and /CentOS 7 .x& 8	`# systemctl disable es40.service # rm -f /usr/lib/systemd/system/es40.service`
