vSphere storage alerts

I’ve been asked about the fact that the storage alerts seem to stop working in vSphere after a while and stop updating. I spent a little while looking into and a it turns out this is a known issue and can be seen in the vSphere 4.1 update 1 release notes. The solution is simple if somewhat annoying, you need to modify the rule to effectively re register it. VMware recommends simply changing the description. This will have to be done after every time the vCenter service restarts
