I've been asked by a colleague if OCI shows the IO Group or controller owner for an individual LUN. I can't see an option to display this information. Does anyone know of a way to show this information?
What version of OCI are you running? OCI 6.4.1 and higher has the notion of a "node" introduced into OCI, as well as HA Pair. We have SVC node visibility as of OCI 6.4.3, or if you have installed Service Pack 220.127.116.11 / 18.104.22.168 onto OCI 6.4.1/6.4.2 respectively
I honestly forget if we show one node, or two nodes in the node column for each volume on SVC. I know we show the 2 nodes in an IO group as a HA pair in some of the grouping pull down boxes in some of the performance flows from the right click -> Analyze function.
Currently, the node info does not flow into the OCI DWH, so if you are asking in the context of reporting, we'd need to rethink this.
I am out of the office at a Splunk event today, so I am a bit restrained into looking into this deeper today
If yes, if you right click -> Anayze one of your SVC, do you see all the nodes (controllers) inside the cluster? If you do not, please email me at ostiguy at netapp dot com - I think you may be hitting a known bug that we have a SVC datasource patch for.
