So Radek, would you describe it as a flaw in Ontap which could be addressed in a newer version?
On the other hand, isn't it so that Ontap is communicating with the thirdparty controller which does understand disk spindown.
Let me put it differently....
The LUN disappearing as you put it would be the same as when the thirdparty storage was used independably as standard. However, it would seem that the thirdparty storage controller
is able to support spindle powerdown without hosts noticing the temporary "loss" of the LUNs to which they are connected. So if they can "spoof" the LUN "loss" to standard hosts, would/should this then
not also be possibe if the "host" were to be a v-series?
regards,
Mark
