• HP-UX 11.31 is only supported on specific models. Server models: rp34xx, rp44xx, rp7405, rp7410, rp7420, rp8420, rp6440, rp8440; workstation models: с8000 (ID#100098). Of these models, the current version of Charon-PAR supports rp34xx and rp44xx.
• Ctrl+c in the Charon-PAR console is passed to the emulator's child processes and kills the PuTTY console process (ID#100188). To prevent this behavior, the emulator serial line configuration can be changed as follows:
  
  • Modify the default configuration serial.uart0.device.command="putty -telnet -P 30000 localhost"
    • either to: serial.uart0.device.command="trap '' SIGINT ; putty -telnet -P 30000 localhost", or
    • to: serial.uart0.device.command="setsid putty -telnet -P 30000 localhost"
• PA9-32 continuous output on shutdown: after the guest system has been shut down, the emulator continuously shows  the message PDC CHASSIS:0XDA00 State= OFF until  the emulator is stopped (ID#100190). This does not affect the normal operation of the emulated system. In newer versions, the emulator is stopped automatically. To revert to the previous behavior, a new command can be added to the configuration file:
  system.stop_on_halt = false
  It will disable emulator auto-stop after shutting down HP-UX.
• Low network performance particular in Google cloud environments when a dedicated NIC is configured for the guest OS (ID#100117). This is related to the cloud environment not properly disabling offloading for the NIC as configured on the Linux level. Workaround: use a bridge/NAT configuration where the emulator uses a TAP interface or (ong GCP) configure the instance with gVNIC interfaces.

• HP-UX 11.11 lpmc_em CPU errors (ID#100084). Should this problem occur, the following workaround can be implemented:

  # Stop diagnostics daemon
# /sbin/init.d/diagnostic stop
# Set config to disable diagnostics
# echo "DIAGNOSTICS=0" >> /etc/rc.config
  
  

• HP-UX 11.11, "btlan: Invalid connection type in SROM" reported in dmesg. This message does not affect network operation (ID: 100118).
  

• MPE Virtual tape errors/timeouts when restoring large backup (ID#100130). Workaround:
  Force the store to use sequential (instead of index read. Enter the following command before restoring the backup:
  :setvar hpfastsearch false.
  
• The emulator currently has no serial port flow control protocol on telnet port (ID#100080).
• When installing the aksusbd package version 8.13 in some CentOS 7.x environments it was observed that the aksusbd service did not start automatically after a new installation or an upgrade. The following error was displayed during the installation: Failed to restart aksusbd.service: Access denied. If this happens, uninstall the aksusbd package and reboot the system. After rebooting the system, re-install the package. The cause of this sporadic problem has not yet been identified.
• When using shutdown -r now on HP-UX 11.31, HP-UX does not enter the GSP console. It works correctly with shutdown -h now (ID#100205).
• Repeated MMU assist off messages may be displayed. This message means that the MMU assistance module detected an unsupported guest OS. It is normal to see these messages during a reset and when the guest OS is starting (when the guest OS is not available).
• If running the Charon emulator host in a Nutanix VM, it must be ensured that Nutanix host partitioning be configured in a way that the emulator's domain (node) does not conflict with or share any resources with other nodes. Failing to do so can cause low performance and instability.
• TOC in HP-UX on an emulated rp7400 system when the configuration contains SCSI controllers on the second system bus (ID#100221).
• On a 720 model, the installation of HP-UX fails if a 20GB disk is configured. It works with a 10GB disk (ID#100244).
• Text mode curses applications may not work correctly on the serial console (ID#100252).
• Ethernet interface DMA error on boot (ID#100256).
• Maximum size for SCSI disks is currently 2TB (ID#100258).
• Unexpected halt during Oracle test on HP-UX 11.31 (ID#100262).
• The emulator sets the default physical serial line parameters during boot unless set explicitly by HP-UX (ID#100245). Workaround: use the port_defaults parameter in the configuration file to set the correct parameters.
• Some application workloads may show  performance degradation when going from 11.11 to 11.23 or 11.31 (ID#100225).
• When configuring the emulator to use TAP interfaces, 32-bit models cannot use an already existing TAP interface. In such cases, the emulator will exit with an error message (Unable to open TAP device).
• VE licensing: connection to a non-default license-server port does not work in this version. It is not possible to specify a port number in the license server address.
• SSH-based data transfer performance and overall CPU load on the guest system are influenced by the SSH encryption method used. On Rocky Linux 8, a higher level encryption is used by default which can lead to a lower performance of the guest system when compared to older guest operating system versions. Possible workaround: configure SSH with less demanding parameters (e.g.,  -o 'Ciphers aes128-ctr' -o 'MACs umac-64-etm@openssh.com'). Caveat: this also makes the connection somewhat less secure.
• If a VE license is used, the emulator must always be run as root. If this is not the case, a misleading error message ("wrong passphrase" is logged instead of the real reason.

Version 3.0.7 Build 22100

...

• The charon-report tool failed (ID#100193).
• The Infineon SmallTalk application could not start, and emulator showed reserved instruction errors (ID#100194).
• MMU assistance was off on certain emulated models due to a problem with memory layout (ID#100197).
• Trap handling problem when using FPU fast-mode (-F) (ID#100199).
• The LSI/SL 53C1xxx controller family is now supported by the emulator (ID#100189).
• The configuration file templates for the emulated rp3440,rp4440, and oversized rp7400 models are now available (ID#100203).
• Extended TLB size for certain rp7400 and N4000 models (ID#100207).
• PA9-32 continuous output on shutdown: after the guest system has been shut down, the emulator continuously showed  the message PDC CHASSIS:0XDA00 State= OFF until  the emulator was stopped (ID#100190). This did not affect the normal operation of the emulated system. By default, these messages are no longer shown. To revert to the previous behavior, a new command that will disable the auto-stop feature can be added to the configuration file:
  system.stop_on_halt = false
• Message reserved instruction c0000000 (0x30, OP_CTL(0, 0x0)) <--> (0x30, 0x0) is no longer shown (ID#100212).
• When creating a fingerprint file, if it does not contain the data required by the Stromasys licensing concept, hasp_srm_view shows an error message and the reason for the problem (e.g., aksusbd not running) (ID#5623).
