Thanks,I read the link  just now,But I would like to do it manually(Just because I am not often to do it).Would you like to tell me the sequence about shutdown?


I really depends if you are on hosted-engine or not and if on hyper converged or not, if power management is configured and so on.
If not hosted-engine at all and no power management, I'd suggest:

shutdown:
1. shutdown all VMs
2. set host1 and host2 in maintenance mode from the engine (just to ensure that all the locks on storage side are properly removed otherwise the restart could take more time)
3. shutdown the engine host
4. shutdown hosts
5. shutdown your SAN

start:
1. start the SAN
2. start hosts
3. start engine host
4. remove hosts from maintenance
5. start VMs
 
 
Like as:
shutdown>>
    step1:shutdown all VMs is running
    step2:shutdown host1
    step2:shutdown host2
    step3:shutdown engine
    step4:shutdown FCSAN storage
start>>
    step1:start FCSAN storage
    step2:start engine
    step2:start host1
    step3:start host2

I don't know whether I am right.
