------------------------------------
Summary: Channel Closed error after SSVM and CPVM agents reconnect
back to clustered management server after host is disconnected.
Key: CLOUDSTACK-7553
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7553
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0
Reporter: Min Chen
Priority: Critical
Fix For: 4.5.0
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.
