Pool column and N/A value

[i5513]

Hello,

We have 2 stores ((IBM) NetApp Model N6070). Disk Tables at OSM (OnComand System Manager) are different on stor1 and stor2. At Pool column we can see at stor2 all disk assigned to Pool0, but on stor1 we see that disk assigned to partner have assigned "N/A" at Pool column:

Do you know why that is happenning ?

Thank you
