dump_concurrent_on(5) File Formats Manual dump_concurrent_on(5) NAME
dump_concurrent_on - enable/disable option for system to dump memory using multiple dump units when a kernel panic occurs VALUES
Failsafe Default Allowed values Recommended value DESCRIPTION On large systems, the time required to dump system memory when a kernel panic occurs can be excessive or even prohibitive, depending on how much physical memory is installed in the system. Concurrent dump capability results in faster dumps by dividing the task to different dump units which can execute in parallel. The default value for The system determines whether or not to dump with multiple units based on the resources (CPUs and disks) available on the system and the properties of the drivers. The (see crashconf(1M)) command and its associated configuration file control the dump concurrency mode in the memory dumps associated with a system crash. On rare occasions, the system may crash before is run during the boot process. On those occasions, the configuration set using the tunable will be used. Who Is Expected to Change This Tunable? Only HP Field Engineers should change the value of this tunable. Restrictions on Changing Changes to this tunable take effect immediately. When Should the Tunable Be Turned On? This tunable should be turned on to allow dumps to dump with multiple dump units when there is a system crash if there are sufficient resources. What Are the Side Effects of Turning the Tunable Off? Dumps may take more time. When Should the Tunable Be Turned Off? The tunable should be turned off if there is a problem using multiple dump units. What Are the Side Effects of Turning the Tunable On? The system decides whether or not to use multiple dump units based on the resources available. What Other Tunables Should Be Changed at the Same Time? None. WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of HP-UX. Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation, some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun- able values, consult the documentation for the kernel software being installed.
