10.19 Collecting a Crash Dump File Using Deferred Dump


10.19 Collecting a Crash Dump File Using Deferred Dump
In XCP 2290 or later and Oracle Solaris 11.2 SRU11.2.8.4.0 or later, the crash dump file may be saved in memory until the system is rebooted after the system crashes.
During the rebooting of the system, the crash dump file is extracted from memory to the file system defined by the dump configuration.
After these files are written, the system is automatically rebooted to the normal multi-user configuration.
This process is called deferred dump. When this deferred dump is used, the system can return to the operational status in a short period after the kernel panic.
For details on deferred dump functions, see the Managing Devices in Oracle Solaris for your Solaris version.
