ESX <-> PhysicalHost_NimsoftVmwareRedirector should be equal in number, it is a one-to-one mapping.

The root cause is due to 173,390 PhysicalHost_NimsoftVmwareRedirector models in the SSdb database.

Environment

Release : 10.4.1

Component : Spectrum Integrations

Resolution

Download the attached CleanupNimsoftProxyRedirectorModels.sh script file from this KB article.

Copy it to the $SPECROOT/vnmsh/ directory.

Logged as Spectrum Install Owner account run the script. It may take 24 hours or more to finish, depending on the number of PhysicalHost_NimsoftVmwareRedirector models.

Before running the script, disable the scheduled OnLineBackup. But run an on-demand OnLineBackup.

bash -login

$ cd vnmsh

$ ./connect

$ ./CleanupNimsoftProxyRedirectorModels.sh

Once it is finished successfully, make an OnLineBackup of the SSdb database.
