In this post series I will share all my experience with HMC downsizing activity and explain how I deal with different challenges I found in downsizing HMC.
1. Use GetOABCASPoolDefault.xml to get the CAS Pool Name
2. Use Get OABCAS.xml to know which CAS servers are member in CAS Pool for OAB
3. Use DeleteOABCAS.xml to delete CAS that will be decommissioned
And one of the best practices for CAS decommissioning in HMC environment is to shutdown CAS Servers that will be decommissioned for a certain time and check that everything in the HMC environment is working good
In the next post I will continue with the decommissioning preparation activities related to MBX server role and MPS activity related to it, followed by 3rd and 4th steps for downsizing activity, this will be coming soon be tuned.
As a conclusion HMC downsizing activity need some planning and should be done carefully to avoid any risk that can affect the HMC production environment.
