Hi, there.

The problem was solved via reset configuration to default:

• IPMI

  1. Maintenance → Factory default

  2. Select second option "Remove current settings and restore to factory default"

  3. Restore

• BIOS

  • Supermicro recommends unplug a VBAT battery from a motherboard and plug it in.

    • At least there is a sense to reset BIOS remotely via IPMI.

Reset the IPMI is pretty safe because the network configuration will be preserved.

• Login and password will be reset to default ones:
  • Login = ADMIN
  • Password = ADMIN

Thanks for Supermicro and VMWare support Teams.
