Hi Rick, I understand the time spent over this task and the frustration that you get out of it, apologies for that.
As a side note, we do have an RFE that will allow unmount of a datastore operation via the plugin, and not just deletion.
Such operation can also remove the initiator group from the Nimble volume.
You can use the mount datastore option to mount the datastore on a host in order to avoid the adding of inititator group task.
Additional note: the mapping of 1-1 initiator group and host iqn is also driven by our VVol integration and we had to perform the change.
I hope you find this information useful.
Thanks for your reply.
"Additional note: the mapping of 1-1 initiator group and host iqn is also driven by our VVol integration and we had to perform the change."
I didn't know that yet, if this is indeed needed then so be it, as we would like to migrate to vVols then we just have to accept this for now.
Additional question: Do you possibly know if the max volume limit will be upped, as we have about 1500 VM and the current volume limit is 1024 we can't use vVols yet.
