Hello, could you try this first and see what it's like?

Can you tell me where can be a problem? There are some new setting in idrac9 and 15th generation?

Because previous generation worked only with these settings (see in the pic).

Hi, please check these articles, they may helpful. 

iDRAC may stop accepting remote IPMI commands after importing iDRAC User attributes with "Password Hash Values" feature enabled https://dell.to/3mpfRMU

Thanks for your reply but I have no error msg, I didn`t import any config,  I have blank msg from idrac... but you ispired me and I tried random noexist user with the same blank answer. There is a problem is in Windows, respectively in ipmitool.

PS C:\Program Files\Dell\SysMgt\OM_iDRACTools\IPMI> .\ipmitool -I lanplus -H 192.168.1.63 -U random -P random sdr list full
PS C:\Program Files\Dell\SysMgt\OM_iDRACTools\IPMI>

Problem is not solved because there is anoher problem with verification.

There is no user verification. root with random pass has the same answer.

PS C:\Program Files\Dell\SysMgt\OM_iDRACTools\IPMI> .\ipmitool.exe -I wmi -H 192.168.1.63 -U root -P calvin chassis power status
Chassis Power is on
PS C:\Program Files\Dell\SysMgt\OM_iDRACTools\IPMI> .\ipmitool.exe -I wmi -H 192.168.1.63 -U root -P blabla chassis power status
Chassis Power is on

Hello, might I suggest instead of existing root/calvin how about making another account and try?

You are one step behind me

 I already try it yesterday. There is need no acc, I can use random noexist user or password.

Could you check your IPMI with this? https://dell.to/3zVyrzq.

Guys I appreciate your effort but ipmi is ok because I can see output of power status or sdr list full.

But I`ve checked ipmi via troubleshooting is you want and test was ok.

There is a problem with authetication process...idrac accept anyone as guest probably,

I`ve tried no user with blank password.
