Hi guys

 

We're facing an issue when mapping new LUNs to Solaris 11: new LUNs of 300GB differ in sectors at Solaris level compared to old 300GB LUNs

The storage array is a NetApp FAS running Data Ontap 8.2.3 7-mode, FC SAN. From the storage perspective the ammount of blocks in the LUNs are the same 322163441664 so to the OS should appear the same, not a bit of difference.


Ideas, suggestions?
