红帽全球峰会19.3. IBM Z 硬件支持的固件转储机制
IBM Z 系统支持以下固件支持的转储机制：
-
独立转储 (sadump) -
VMDUMP
IBM Z 系统支持并使用 kdump 基础架构。但是，使用 IBM Z 的固件支持的转储(fadump)方法之一有以下优点：
-
系统控制台启动和控制
sadump机制，并将其存储在IPL可引导设备中。 -
VMDUMP机制与sadump类似。此工具也从系统控制台启动，但会从硬件检索生成的转储并将其复制到系统以进行分析。 -
这些方法（与其他基于硬件的转储机制类似）能够在
kdump服务启动前捕获机器在早期启动阶段的状态。 -
虽然
VMDUMP包含接收转储文件到 Red Hat Enterprise Linux 系统的机制，但VMDUMP的配置和控制是从 IBM Z 硬件控制台管理的。
