Manually upgrading the VCS configuration file to the latest version


Manually upgrading the VCS configuration file to the latest version
Prev	About AdaptiveHA	Next

The VCS configuration file (main.cf) gets automatically upgraded when you upgrade from older versions of VCS using the installer.

If you chose to upgrade VCS manually, ensure that you update the VCS configuration file to include the following changes:

The Capacity attribute of system and Load attribute of service group are changed from scalar integer to integer-association (multidimensional) type attributes.

For example, if the System has Capacity attribute defined and service group has Load attribute set in the main.cf file as:
```
Group Gx (
 ....
Load = 20
)
System N1 (
....
Capacity = 30
)
```
To update the main.cf file, update the Capacity values for Load and System attributes as follows:
```
Group Gx (
 ....
Load = { Units = 20 }
)
System N1 (
....
Capacity = { Units = 30 }
)
```

If the cluster attribute HostMonLogLvl is defined in the main.cf file, then replace it with Statistics and make the appropriate change from the following:

Replace HostMonLogLvl = ALL with Statistics = MeterHostOnly.

Replace HostMonLogLvl = AgentOnly with Statistics = MeterHostOnly.

Note:

For HostMonLogLvl value of AgentOnly, no exact equivalent value for Statistics exists. However, when you set Statistics to MeterHostOnly, VCS logs host utilization messages in the engine logs and in the HostMonitor agent logs.

Replace HostMonLogLvl = Disabled with Statistics = Disabled.
