증상
在遇到电源重置并恢复服务器供电后，服务器无法启动至安装在 iDRAC vFlash 上的操作系统。 几分钟后，服务器能够启动至 vFlash 和操作系统以启动。错误消息为“no boot device available found”（找不到可用的启动设备）
原因
在 iDRAC 完全初始化之前无法访问 vFlash。供电中断后，iDRAC 卡将关闭并需要几分钟时间进行初始化。在此期间，风扇以其最大速度旋转。
此外，
不支持将操作系统安装到 vFlash。
这适用于 iDRAC 6、7、8 和 9。 第 14 代的 iDRAC 用户指南将进行更新以反映这一点。
支持的配置
可以在存储在 vFlash 中的可启动 IMG/ISO 上启动。
启动至分区
- 您可以将连接的 vFlash 分区设置为下一次启动操作的启动设备。
- 在启动分区之前，请确保 vFlash 分区包含可启动映像（.img 或 .iso 格式）以从设备启动。
- vFlash 功能已启用。
- 您拥有访问虚拟介质权限。
