下面以Linux系统为例，介绍一下重置idrac root密码的方式。

2、解压，安装RACADM

[root@localhost ~]# racadm getconfig -u root
# cfgUserAdminIndex=2
cfgUserAdminUserName=root
# cfgUserAdminPassword=******** (Write-Only)
cfgUserAdminEnable=1

[root@localhost ~]# racadm set iDRAC.Users.2.Password calvin
[Key=iDRAC.Embedded.1#Users.2]
