Solved: Openstack NetApp cDOT iSCSI driver in Havana, how can you specify a volume for LUN provisioning?

parrizas · ‎2014-01-30

Hi,

Is it possible to tell Havana in which volume should LUNs be provisioned? By the driver options you may tell Havana which vserver shoud be used... but i don't see any available option for volumes.

If you don't have any volume in the vserver, will Havana create a volume before creating the LUN? or should you manually provision the volume beforehand?

Thanks a lot in advance!!!

In Havana you can only tell the 7 mode driver which flexvols it should use while provisioning by using netapp_volume_list. In cDOT the functionality is segregated around vservers and the thinking is that if you want to group resources according to workloads or any other criteria, then you can do it by creating different vservers. Flexvols need to be present before creating luns, driver does not create flexvols.

The NetApp driver will NOT create any flexvols for you, you need to create them yourself. The driver will use any of the flexvols owned by the vserver to create LUNs.
