Hi,
In the ESXi host, wehad a couple of DIMMs replaced, an Advanced Feature Key and a RAID controller battery pack. We also did a complete firmware upgrade to the same firmware level as another host in the production as well as the change in “BIOS settings” recommended by IBM as a workaround to “ROM space error” .
After this, the host is down and we are unable to bring it back to network. I have tried almost all the checks - restarted the management agents, restarted the network management, the network link is up but still the issue persists.
Can anyone recommend what is the issue and what is the next possible check that can be performed?
