Crash dump, the ability to write (dump) a copy of system memory onto disk in the event of a catastrophic system failure, is critical for system problem analysis and resolution. The Crash Dump utility has been enhanced in HP-UX 11i v3 to significantly increase performance and scalability, and to improve the availability and manageability of the dump configuration. Dump performance is important because the amount of time it takes to perform a dump impacts directly the availability of a system. This is particularly true on large memory systems, because the more memory one has the longer it may take for the system to complete the dump and come back up.
