- Second DB server can't see any initiators problem:
The second DB & the first DB both are VM and located on same physical server and connect to same DataStore in ESX. So suppose they should see the same FC initiators. The first DB server can see the FC initiators and success create SnapDrive but on second DB server it show nothing on Initiator page during create disk so can't complete the SnapDrive create. Really have no idea why the second DB can't see any initiator. Both VM has same resource assign from VC. Any area I can look for the reason why it won't show the initiators?
