I have a box with SuperMicro X9DRW-iF mainboard. It has built-in BMC module, which provides IPMI interface and web-GUI for it.
After upgrading BMC firmware from R 2.35
to R 2.59
under web-GUI ("Network" and "IPMI" options was checked in "BMC Preserve Configuration" screen, "Preserve all Configuration" option was unchecked) BMC module restarted, accessible via both HTTP and SSH, but rejects my login attempts with default login and password (ADMIN/ADMIN) via both HTTP and SSH.
Before firmware upgrade there was only one user in IPMI - the default one (ADMIN/ADMIN).
Where did I go wrong? What should I do to restore access now? I only guess to re-flash firmware with some Linux stuff on local system on this box, without preserving any BMC config, to bring it generally to factory defaults.
