Blog 1 - Disable Autorescan Vcenter 4.x
You can't, you won't, and you don't stop... Enterprise storage admins loathe the autoscan feature in VCenter 4.x + beyond. If you have tens or hundreds of datastores and cluster sof 7 or so ESX hosts waiting for the rescans to complete can slow zoning reconfiguraitons, dirver updates or software implementations. Using the following command you can stop and start this feature NON Disruptively as no service restarts are required!
- Open the vSphere Client.
- Go to Administration > vCenter Server.
- Go to Settings > Advanced Settings.
- If the config.vpxd.filter.hostRescanFilter key is not available, add the key and set it to False.
