> 1. Set up a clustered management server setup using Vmware. Note down the MS id that
SSVM agent is connected to from DB host table.
> 2. Disable uplink on hypervisor host that runs SSVM. Now in the log we should see Channel
is closed error, which is correct and as expected.
> 3. Waited for some time, enable uplink back on hypervisor, SSVM agent will reconnect
back to MS. Make sure that SSVM agent is connected to a different MS node from the one we
noted down in step #1. If not, try #2 and #3 again until that happens.
> 4. Now we will continue seeing "Channel is closed" error from the MS log noted down in
step #1, this is not correct. Command sent to SSVM will fail if the command is sent from MS
node noted down in step #1.
