add 15K RPM disks to a volume that has 10K disks

[prakash_aviva]

Hi,

Ww have a FAS 270 filer with DO 7.0.1 and we need more disks to add to the filer.

Can we add 15k RPM disks to a volume that has 10k disks ?

I know this is available in current product (though not recommended), just want to be sure for FAS270.

Please suggest.

Yes it possible and yes you're right not recommended, but now days with only 15krpm disks available do we really have a choice , for these older systems.

Have a look at http://now.netapp.com/NOW/knowledge/docs/ontap/rel80/html/ontap/smg/GUID-BE0475EA-4BB1-4544-ADC8-B0EADAB6C2D3.html for various parameters.

Recommend you upgrade your DOT also a your lastest supported version is possible.

Hi Ranil

This is because of the rather old ontap version you are running. In order to get the new disks recognised, you will need to update at least the "disk qualification" file. I'd also recommend you to do a Ontap upgrade (which then includes the disk qualification). And also the options will appear with the new ontap.
