Bear with me a bit while I try to get the details of this upgrade laid out. I have read all the KB's and blog posts and I'm still unclear on some of the phases of the process. Here is the plan in place right now:
vCenter 4.0 32bit
12 ESX hosts on 4.0
standard vSwitches for management and vCenter access, these are on dedicated gigabit NICs
Nexus 1000v VEM with port profiles for all our hosted VMs, these are on separate CNAs
Where this is going
vCenter 5.0 on a new VM, keeping existing SQL db
1000v VSMs disconnected from old vCenter, re-connected to new vCenter
12 ESX hosts kept at 4.0, reconnected to new vCenter 5.0, will be upgraded in phase 2
no change to standard vSwitches
Nexus 1000v VEM modules need to re-connect to VSM on new vCenter
There's no real all-in-one doc for how to do this, so here's what I've been able to piece together based on KBs, blogs and forum posts
verify all 1000v VEM and VSMs are on latest version
power off VM's that rely on 1000v port profile/vDS, migrate them to a standard vSwitch
remove any other configs dependent on 1000v (vmotion, FT ports)
disconnect all VEMs from VSM, verify no registraitons are on the VSM
disconnect VSM from vCenter 4.0
perform upgrade/migration of vCenter 4.0 to vCenter 5.0
move one host over to vCenter 5, make sure VSMs are on that host
re-register VSM with vCenter 5.0
install VEM on host, verify VSM has the correct port profiles for packet, control, management
begin re-attaching hosts to vCenter 5.0
re-register hosts with the 1000v, redeploying VEM
reconfigure ports for vmotion and FT
verify VMs have correct port profile, power on VMs
Am I in the ballpark or is there a better/easier way that may not require me to shut down every VM? I would appreciate ANY feedback or comments on this as I'm pretty much flying solo in the planning and execution of this upgrade.
Usually, we can access ESXi Shell by pressing Alt+F1 from ESXi DCUI (Direct Console User Interface).
But on HyperFlex system, it just shows black window.
This is expected behavior because HyperFlex redirects ESXi Shell output to SoL...
