R420服务器idrac连接用户数超限制

Dell R420服务器中,比较经常出现idrac无法连接,或者连接用户数超限(RAC0218错误)的问题,升级iDrac卡firmware至1.57.57即可解决。

该版本的bug fix中提到过一点:

  • Fix for issues that cause iDRAC7 sluggish responsiveness after a prolonged period of time (approx. 45-100 days, depending on the usage). In some cases, if the iDRAC is not reset, the iDRAC may become unresponsive and requires a server AC Power on reset. This issue was introduced in firmware release 1.50.50 and fixed in 1.56.55.

RAC0218: The maximum number of user sessions is reached.

2种临时解决方法(idrac重新初始化)

  • 长按前面板i键20秒,idrac会重启初始化 (建议使用这种方法,无需重启服务器)
  • 关机后拔掉电源线,长按电源开关按键15秒,再插上电源线开机

tftp server准备
