Is it possible to change disc performance (Tier) on a running instance?
Posted by on 26.10.2012 15:18

Yes, but this functionality concerns only unshared discs. The instance where is plugged at least one shared disc in precludes changes of Tier class for each kind of disc plugged to this instance in. To make changes, you have to unplug all shared discs or turn off the instance first. Be advised that you can not change Tier class of the disk if the OCI instances attached to it contains snapshots.
