About "Number of AU's Assigned to This Aggregate" section in Storage-pool-aggr.xml's Autosupport

Hello people

quick question about section "Storage-pool-aggr.xml" of any Autosupport.

There is a label/field/column "Number of AU's Assigned to This Aggregate" with a number for each aggregate non-root.

What is exactly the meaning of that number specifically? what does it represent?

thanks n Rgds

Name of Storage Pool	Nodes Sharing the Storage Pool	Aggregate	Number of AU's Assigned to This Aggregate
Storage_Pool_01	jbmoriasoft01-cl01-01 , jbmoriasoft01-cl01-02	aggr0_SAS_Node1	2
Storage_Pool_01	jbmoriasoft01-cl01-01 , jbmoriasoft01-cl01-02	aggr0_SATA_Node2	1

hi @JavierBarea

when you create a storage pool, the SSDs are partitioned in 4 equal size partitions, these partitions are then grouped together in an Allocation Unit which you can assign to an aggregate.

Ok, thanks

Got It Now

Maybe if The column name-label was "number of Flashpool AU's assigned" , my question could have been avoided.

BEST regards and thx again
