The issue happens randomly when hosts in a cluster gets distributed across multiple MS. Host can get split in following scenarios:
a. Add host – MS on which add host is executed takes ownership of the host. So if 2 hosts belonging to same cluster are added from 2 different MS then cluster gets split
b. scanDirectAgentToLoad – This runs every 90 secs. and check if there are any hosts that needs to be reconnected. The current logic of host scan can also lead to a split
The idea is to fix (b) to ensure that hosts in a cluster are managed by same MS. For (a) only the entry in the database is going to be created except in case if the host getting added is first in the cluster (in this case agent creation happens at the same time) and then (b) will take care of connection and agent creation part. Since currently addHost only creates an entry in the db there is a small window where the host state will be shown as 'Alert' till the time (b) is scheduled and picks up the host to make a connection. The MS doing add host will immediately schedule a scan task and also send notification to peers to start the scan task.

Description:
Deleting the row in cluster_vsm_map after
a cluster is deleted, if the cluster type
is vmware and the global vswitch nexus
config flag is set to true.
Description:
Removed the vcenter_dc_name and vcenter_ipaddr
fields from the virtual_supervisor_module
table, the CiscoNexusVSMDeviceVO, addClusterCmd,
and all other references to these two fields.
Fixing null pointer exceptions when checking
for nexus related global parameter values in
addClusterCmd.

Description:
Adding an optional flag to the addCluster command,
"addvsmflag". If this is set to true, the API will
throw an exception if any VSM parameter is missed
out. The above bug was running into a DB exception
because the vCenter ipaddress wasn't passed in and
the API didn't catch it.
Description:
Didn't stage all modified files in previous
commit by mistake. Checking in the rest of
the changes in this commit. Please refer to
immediate previous commit for CS-9919 for
details on what changes went in with this
commit.

Changes:
- While listing UP hosts in the cluster of the host, the query has changed and now also considers the Host 'resourceState' field and picks only those hosts that have value 'enabled'.
This query result does not include the host being put in maintainance; unlike the earlier query that used to include it.
- But the logic to find out if this is the last host in the Cluster is not updated and has a bug when it compares the list size.
- Fixed this.
