10 Error Logging This section contains information about the way Integrity VM logs messages. 10.1 Guest Log Can Grow Unbounded The guest monitor log file (/var/opt/hpvm/guests/vm_name/log) records guest start and stop information. These log files can grow very large. Use the hpvmconsole command rec -rotate to close the current log file, rename it, and open a new one. 10.2 Log Messages Written to Old Log File Log messages might be written to the command.log.old file instead of the command.log file. If this is a problem, reboot the VM Host system. This reinitializes the log file for applications that generate Integrity VM log messages to write to the current command.log file. 10.3 Saved MCA or INIT Register State Can Be Inaccurate Virtual machines do not support standard management processor console errdump commands. The virtual console's Virtual Machine menu provides the ed command for this purpose. The options for a virtual machine are -mca and -init. When you examine the saved guest state using the ed -mca or ed -init command, the preserved branch registers (B1-B5) do not always contain accurate data. 10.4 Modifying the Size of the Monitor Log File Integrity VM includes a monitor log (/var/opt/hpvm/common/hpvm_mon_log), which captures the state of the VM Host. The size of the log file is determined by the VMMLOGSIZE tunable, stored in the /etc/rc.config.d/hpvmconf file. When the log file reaches VMMLOGSIZE, the current timestamp is appended to the name of the log file and a new log file is opened. If you see many such files, increase the value of the VMMLOGSIZE tunable. Do not set the value of the VMMLOGSIZE tunable below its 1024 KB default. 10.5 Virtual Console Event Logs Different from Physical Machine Logs The virtual console allows you to use the sl command to list the System Event log and the Forward Progress log. The displays from the virtual console differ from those generated on a physical machine in the following ways: • Event numbering is inconsistent for different lines. • Although the command menu allows you to specify a cell number, virtual machines are not cellular. Therefore, this option is not functional. 10.1 Guest Log Can Grow Unbounded 51
