汉中做网站的电话优秀营销软文范例100字

新开发的PCIE设备在做服务器适配时,有时需要服务器厂家更新BMC或BIOS固件。同时,我们也希望对PCIE设备做一些检测,最后收集一些信息存档。如果需要处理的服务器很多,通过BMC的界面进行人工操作就会比较麻烦。以下提供了一个脚本,供参考。

主要思路:

• 采用haneWIN NFS Server搭建一个NFS服务,目录为nfs,里面存放着boot.iso(设备检测镜像)
• 通过redfish协议登录BMC,获取PCIE设备信息,服务器信息,升级固件,重启服务器,挂iso,设置启动方式
• 截屏获取KVM的内容,通过图片相似度的方法判断ISO里的检测程序是否运行完成.
