Why I did it

Remove the call to SonicDBConfig.load_sonic_global_db_config() in the multi asic functions.
The expection is the client calling this function will call SonicDBConfig.load_sonic_global_db_config()

This PR is dependent on the PR sonic-net/sonic-utilities#1712

How to verify it

        swsscommon.SonicDBConfig.initializeGlobalConfig()

Is it same as load_db_config()? If yes, we can call that function, and remove device_info from this file.

RuntimeError: SonicDBConfig already initialized

Hi Qi,
As discussed this error is caused because of the following sequence:

  • For every CLI the file utilities_common.cli is imported. In this file we initialize the global variable
    iface_alias_converter = InterfaceAliasConverter()
  • In the init of the class InterfaceAliasConverter we call theconnect_config_db_for_ns()with namespace option
    For single asic the namespace is default_namespace(“ “)
  • In the init of the sonicV2connector class we call the function get_db_list().
  • In this function if the db is not initialized we initialize the db.
    Thereby loading the database file
  • So in main.py when we try to initialize the db again it errors out

To prevent this error, added a new function load_db_config in sonic-utilities to safely load the database config files.
the changes are in PR sonic-net/sonic-utilities#1712.

Load the database global_db. (#1752)
5002745 
What I did
Recent change was done to remove call to load database global_db which expects the clients to load global_db.
[sonic-net/sonic-buildimage#8173]
The load global_db was missing in multi_asic.py which was causing "show interfaces cli" to fail.
While testing on multi-asic VS image:
How I did it
load global_db config in multi_asic.py.

How to verify it
Load multi-asic VS image with the fix.

[multi-asic]: Add function to load database config (#4112)
f6586d6 
What is the motivation for this PR?
With the changes in sonic-net/sonic-buildimage#8173, the applications that connect to namespace dbs have to load global database configuration. Due to this change, the sonic-py-common.multi_asic functions that connect to database will fail if database configuration is not loaded in ansible library functions.

How did you do it?
Add a new module_utility library function to load the right db configuration based on single or multi-asic platform.
Invoke this function in port_util and lag_facts where mutli_asic library function is invoked which connects to db.

How did you verify/test it?
Bring up a multi-asic VS testbed.
./testbed-cli.sh -t vtestbed.csv -m veos_vtb -k ceos add-topo vms-kvm-four-asic-t1-lag password.txt
Before adding this change, failure seen while running test_bgp_fact.py
