Dell EMC VxRail: How to update VxRail Manager configuration using script after converging external vCenter and PSC

Starting from vSphere 7.0, vCenter can only be deployed with embedded PSC.

If VxRail is using a user-provided vCenter with external PSC, and the vCenter is upgraded from lower version to 7.0, during which PSC is converged, it is necessary to configure VxRail Manager, or VxRail Manager does not work properly.

1. Download the script provided on: https://download.emc.com/downloads/DL98139_ext_vc_psc_convergence_post_action.py.zip
2. Extract and upload the script to VxRail Manager.
3. Log in to VxRail Manager using SSH and run the following command as root:
   python /path/to/uploaded/script -u <vc_administrator_usr> -p <vc_administrator _pwd> 

Wait for 5-10 minutes for different services to restart, and functions should return to normal.

This script should only be used with user-provided vCenter. If the internal vCenter is converted to external, it is also considered as user-provided, although it is running on the vSAN cluster.

The converging of PSC has different impact on different versions of VxRail.

• For VxRail versions up to 4.5.400 on 4.5 train and 4.7.000, attempts to log in to the legacy UI on VxRail Manager fail.
• Starting from versions 4.5.401 on 4.5 train and 4.7.100 on 4.7 train, login does not fail after converging, but some other functions may be impacted. It is OK to upgrade VxRail to 7.0.000 without running the script, but if there are operations other than LCM upgrade, it may still be necessary to run the script.
