After we finished the installation of the Servers , we should run a inspection for all the servers .
After the inspection , we found that there is a warning :
Active iBMC version is not the same as backup iBMC
Usually we need to upgrade the BMC twice , but the onsite engineer only upgrade the back BMC version .
After the upgrade , the BMC will restart , the backup will be the actived one and the original active one will be the backup iBMC version .
This is why we saw the Active iBMC and the Backup iBMC is not the same version .
When we upgrade the BMC , by default , the system will uprage the back iBMC , then we have to do the upgrade again .
We can uprage this backup iBMC through the web or through the tool uMate .
When upgrading the iBMC , we need pay attention to :
1. This upgrade will not restart the server , so we doesn't need to stop the service .
2. We need to do the upgrade twice .
