Root Cause
User information management of the RH2285 BMC uses two user information lists: one used by the BMC software under the data directory and one used by the embedded system (BMC running platform). Under normal conditions, user information is consistent in the two lists. Adding new users simultaneously creates user information in the two lists. Under abnormal conditions, information about a user is stored in only one user list. As a result, the user can log in to the server successfully only in specific scenarios.


Solution
Use a local PC to log in to the RH2285 and enter the BIOS to change the password of the BMC user root.

Suggestions
Note:
If the server BMC can be logged in to over Telnet without the server restart, perform steps 1, 2, 3, and 4 shown in Figure 8 to restore the default password root for user root.
