 I have a test Domain at the house. This is how I changed the FISMO roles with powershell. Move-ADDirectoryServerOperationMasterRole -Identity "LAMBDC" -OperationMasterRole 0,1,2,3,4 I test that the move happened under operational masters.

 A customer of mine gave me a mid 2011 imac 21.5 to wipe. Then I can do with it what I will. I decided to replace the 1 TB HDD with a 240 SSD. The problem was that I could not use disk utility to create the correct GUID partition map. So I looked at CLI solution. Diskutil allowed me to format the drive correctly. diskutil eraseDisk HFS+ DiskName /dev/DiskNodeID I did this command. But reinstall wanted another format. Follow this to launch internet recovery mode https://www.ifixit.com/Guide/How+to+use+Internet+Recovery+to+install+macOS+to+a+new+SSD/119499 I booted into this program and then used Disk Util to change the MAC OS Extended Journaled.

I had this problem today. Using this diagram I noticed the VPXA service talked to vCenter Server. from http://www.vmlab.com.pl/host-fails-to-update-information-with-the-error-vmware-esx-cannot-synchronize-host/ Then I read this post  So I restarted the services on the host and after 2 minutes the services sync-ed up. We found out that there is a problem with the DNS server. We pinged the node1 in the cluster by the ip address. The ICMP returned with no problems. When we pinged with the node's hostname the ICMP packets we have 50% failure. We turned off one of the DNS servers and the ping to the hostname returned 100% successful.
