Message from my HP LeftHand P4500 : Value exceeds 95

Hello,

 

For few days, I receive some alert from my HP LeftHand Cluster P4500.

Here is the error:

13:53:36 p4500-n1 hydra: Management Group: 'p4500-mgmt'; Cluster: 'p4500-cluster' Utilization = 99.9996. Value exceeds 95.

 

I receive the alert from my node 1 and 2. And sometimes, whe the error occurs I can no longer ping tne node 1. It appears down in the SAN/IQ console. I don't understand the reason of this alert. The SAN is not full. On the console "utilization" is 72%.

 

Here are information on the hardware configuation:

 

Node 1 and 2:

 

Raid 5.

Raw Space : 4,91 TB

Usable Space: 4,01 TB

 

Volume 1 named "HV":

Size : 4.01

Replication Level : 2-Way

Provisoned Space : 8.03 TB

Provisioning : Full

 

Have you got some explanations about this alert ?

Thanks for your help.

 

Fabrice.

why the full provisioned LUN? 

 

If you are trying to make a snapshot of a full provisioned LUN, I believe that snapshot becomes full as well and that would take you over your limit. 

 

There are very few reasons ever to use a full provisioned LUN so my first suggestion would be to convert that and then I bet your problem will go away.

also, I see it says usable space per node of 4.01 and you have a LUN that is provisioned using 8.03... given you only have two nodes, that sounds like 100% utilized to me.
