Was looking for the same solution but my problem was to find IMM IP of remote server and found this tool. Running DSA tool on remote IBM servers (Esxi) will pull inventory of the server to your local Windows server . I tested this on x3850 x5 IBM running esxi 6.0U2 .
Download DSA from this link you will need IBM login to get the tool.

Install DSA on a Windows 2012 or supported OS check the readme file , explains everything .
Command i used as a administrator prompt to get complete inventory:
C:\Users\Administrator>ibm_utl_dsa_dsyte1d-9.61_portable_windows_x86-64.exe --vmware-esxi root:password@IP_OF_ESXI: -v
Once tool is executed and completed you will have all html and xml files downloaded to a local folder . Open it with any browser and you will have all the info of the server.
