Description

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.
