SCOM - Pool usage alerts applying to LUN's

Hi,

In our Clariions we have a large number of Raid groups with LUN's in them. We do not use Pools.

We have sized these Raid groups to more or less exactly the size of 4 of the standard size LUN's we use. This means, logically, that there is almost no free space left in the Raid group.

The EMC management pack for SCOM 2012 has 2 alerts that are being triggered erroneously:

- Subscribed Capacity Percent

- Available Capacity Percent

I could turn these 2 monitors off generally, that would be fine for all our Clariions.

However, we als have a VNX, and there we use pools.  There, I very much do want to be alerted by these 2 monitors.

Problem is, I don't seem to be able to override based on a specific array. I can override on the Object, or on the entire class 'EMC SI Storage Pool'

How can I turn of  of override the alert globally for just the Clarrions, but keep it place for our VNX ?
