If you are upgrading to a new patch of the same release, you must clear the SnapCenter Plug-in for VMware vSphere cache on the vCenter Web Server and restart the server before the upgrade or registration.

If the plug-in cache is not cleared, then recent jobs are not displayed in the Dashboard and job monitor in the following scenarios:

SnapCenter Plug-in for VMware vSphere was deployed using vCenter, and then later upgraded to a patch in the same release.
The SnapCenter VMware virtual appliance was deployed in vCenter 1. Later, this SnapCenter VMware plug-in was registered to a new vCenter2. A new instance of the SnapCenter VMware plug-in is created with a patch and registered to vCenter1. However, because vCenter1 still has the cached plug-in from the first SnapCenter VMware plug-in without the patch, the cache needs to be cleared.

Steps for clearing the cache

Locate the vsphere-client-serenity folder, then locate the com.netapp.scv.client-<release-number> folder and delete it.

The folder name changes for each release.

See the VMware documentation for the location of the vsphere-client-serenity folder for your operating system.
Restart the vCenter Server.

You can then upgrade the SnapCenter VMware plug-in.
