We have a few VMs with LUNs dedicated to them (i.e. SQL VMs), formatted with VMFS and each one containing one vmdk file taking up most of the space on those LUNs (approx 99%). Because of this, the Datastore Usage alarm always shows as critical for these disks. Instead of having to reconfigure the alarm, which would effect how the alarm reports on our shared datastores, is there a way to disable the alarm for particular datastores? There doesn't appear to be. Also, for some reason on this particular alarm, once triggered, I do not see a way to reset the alarm status to green, only to acknowledge.
Thanks
