hpe gen9 服务器ilo4升级中断电，报错270的解决方法
先尝试重置ilo 的按钮长按10 秒，断电10秒后 连接
如果还不行，通过服务器内置的ilo 恢复模式 ftp 上传 ilo固件。
Most firmware upgrades finish successfully. In the unlikely event of server power loss during an iLO firmware upgrade, iLO might be recoverable when power is restored.
When the computer is booting, the kernel performs image validation on the main image. If the image is corrupted or incomplete, the kernel enters Failed Flash Recovery. Failed Flash Recovery activates an FTP server within iLO. The FTP server enables you to send an image to iLO for programming. The FTP server does not provide any other services.
A network client can connect to the FTP server. The user name for the connection is test, and the password is flash. To send a firmware image to iLO, use the FTP client
PUT command. After receiving the image, iLO
validates the image. If the image is a complete, signed, and valid
firmware image, the kernel begins programming the FLASH partition.
After the image is programmed into the FLASH partition, reset iLO by issuing the
RESET command to the iLO FTP server.

关键是用户名 我用的ftp 密码 flash 就可以

折腾了 linux ，esxi 系统里面的升级固件程序都报错。
