Same LUN size but different sectors in Solaris 11

vfukuda1

Hi guys

 

We're facing an issue when mapping new LUNs to Solaris 11: I created new LUNs of 300GB but according to the Solaris administrator the new LUNs are not exactly the same as last LUNs mapped

Any ideas?

 

The ammount of blocks in the LUNs at Data Ontap level are the same 322163441664

Can you post the output of lun show-instance for each of them?

 

thanks!

It's Data Ontap 8.2.3  7-mode so I suppose the equivalent output would be:

 

MLIMASAN02> lun show -v /vol/lun_Data05_vol/lun_Data05
        /vol/lun_Data05_vol/lun_Data05  300.0g (322163441664)  (r/w, online, mapped)

Where LUN Data05 is the old one and Data15 the new LUN I created (as usual)
