You might have faced issue with IBM IMM (Integrated Management Module) also called IBM RSA that IP address or IMM name (simmilar to host name) is pinging but you are not able to open webpage. It is painful in the situation when you want to perform reboot, any firmware upgrade, to check server os status from remote location, To sort out you need to reset (restart) IBM IMM not server.
Follow below steps to reset IBM.
Open command prompt (you can use putty as well, here I will demostrate with Microsoft command prompt)
Start → run → cmd
Type Telnet appending by your IBM IMM IP address or IMM name press enter.
Telnet xxx.xxx.xxx.xxx or Telnet IMM_name
Enter user login (userID) and password.
Now on next screen type resetsp and press enter to reboot IBM IMM as below screenshot.
resetsp
It will loose connection for 1 or 2 min.
Open IBM IMM ip in web browser, and its done.
