CharonPlease note: Charon-PAR can also be configured to start automatically as a daemon when the host system boots and to be stopped when the host system is shut down. However, such a configuration requires that the user shut down the guest OS cleanly before the emulator is stopped. Failure to do so can cause data corruption in the guest system. Contact your Stromasys representative for support if you require such a configuration.

...

Configuration from the PDC console.
Configuration from HP-UX.

Autoboot Please note: Autoboot will be interrupted if a configuration change occurs which causes reduced performance to allow manual intervention. This can be overridden by enabling autostart in addition to autoboot on the PDC console. However, this is not recommended as it is important to understand the cause of the problem.

...

To enable autoboot from the Charon-PAR/PA9 PDC console before system boot, perform the following steps:

	Step	Description / Command
1	Start the emulator.	`# /opt/charon/bin/charon-par -f </path-to/configuration-file>`
2	Enter menu mode.	At the prompt Main Menu: Enter command or menu > type menu. This will display the available menu options.
3	Enter the configuration menu.	Type `CO` to enter the configuration menu. This will display the available configuration options.
4	Activate autoboot.	Type `auto boot on` to enable autoboot (or use the abbreviation `au bo on`). Autoboot is now enabled for the next boot.
5	Restart the emulator.	Stop the emulator: enter the exit command at thepa3>, pa9-64>,orpa9-32>prompt and hit Enter. Start the emulator again as shown in step 1.

Follow the steps below to create and apply the SLT:

78

	Step	Commands
1	Copy Boot the system and log in as the Manager. Then copy the supplied autoboot file, and load the virtual tape file on LDev 7. LDev 7 (this virtual tape was configured in the installation example provided in this documentis preconfigured in SYSGEN as device 0/0/1/0.6.0 (virtual tape MKA600 using container ldev7.img in the example). Wait for the message " `Vol (unlabelled) mounted on LDEV# 7` " to appear on the console, and continue.	`:HELLO MANAGER.SYS` `:COPY AUTOBOOT.CHARON, AUTOBOOT.PUB` `:DEVCTRL 7;LOAD=ONLINE`
2	Use sysgen to specify the new autoboot file and write the SLT. The line with the ? is a prompt asking for the tape number and a PIN. The PIN is represented in the sample here by the string XXX. Use the number shown in place of the XXX.	`:SYSGEN` `sysgen> sysfile` `sysfile> aauto autoboot.pub.sys type=disc` `sysfile> hold` `sysfile> exit` `sysgen> tape` `?19:00/#S2/XXX/ LDEV# FOR "SYSGTAPE" ON TAPE (NUM)?`
3	Respond to the prompt.	Press CTRL-A. This will display an `=` character. Type `REPLY XXX,7` after the = character replacing XXX with the number displayed in the prompt. Confirm with the Enter key.
4	Wait for the message "`boot tape is successfully built`" before you continue.
5	Exist sysgen, respond yes to the question if you really want to exit, and then shut down the system.	`sysgen> exit` (...) `Configuration changes are not kept yet!` `Still want to exit (yes/no) ? yes` `: shutdown system`
6	Stop and restart the emulator.	To stop, type exit at the Charon-PAR pa3> console prompt. Then restart the emulator.
7	Reboot the system from the virtual tape on LDEV LDev 7. Then update the system with the files from the virtual tape.	At the prompt `Main Menu: Enter command or menu`type boot alt (the default alternate boot path is LDev 7; if you change it, boot using the device path of the tape). At the prompt Interact with IPL (Y or N)? type Y. At the ISL prompt type `update config`.
8	The system will display the list of files that are updated. Wait for this to finish.
9	Boot normally. This should now be possible without interacting with IPL.	At the prompt Main Menu: Enter command or menu type `boot`. At the prompt `Interact with IPL (Y or N)?` type `N`.

After Please note: After this step, the virtual tape container (ldev7.img in the example) can be removed or archived. It is no longer needed.

Enabling Autoboot on the PDC Console

To enable autoboot from the Charon-PAR/PA3 PDC console before system boot, perform the following steps:

	Step	Description / Command

2	Enter menu mode.	At the prompt Main Menu: Enter command or menu > type menu. This will display the available menu options.
3	Enter the configuration menu.	Type `CO` to enter the configuration menu. This will display the available configuration options.
4	Activate autoboot.	Type `auto boot on` to enable autoboot (or use the abbreviation `au bo on`). Autoboot is now enabled for the next boot.
5	Restart the emulator.	Stop the emulator: enter the exit command at thepa3>prompt and hit Enter. Start the emulator again as shown in step 1.

...

To disable autoboot, follow the steps above, but use the command auto boot off instead.
