No there is no option like do not send alert. Moreover, Storage Pool percent full alert threshold the maximum percentage is 84. So it won't allow you to apply the setting if you enter an integer above 84 and below 1.  However, I believe as a work around you may modify the template and uncheck the alert code, but it will disable the alert for all the Storage Pools. Personally, I would not recommend that.
Hi all, is there a way to disable storage pool alert?  thanks
