Luke,
In order for a node to be a gateway node, a GPFS server license designation is required. Essentially, a gateway node acts as a server between the nodes regardless as to whether the data is coming from a GPFS file system or not. You can't set a node to be a gateway node without first designating it as a server via mmchlicense.

[root@sym1 ~]# mmchlicense client --accept -N sym3
The following nodes will be designated as possessing client licenses:
sym3
mmchlicense: Command successfully completed
mmchlicense: Propagating the cluster configuration data to all
affected nodes. This is an asynchronous process.
[root@sym1 ~]# mmchnode --gateway -N sym3
Thu Nov 10 10:08:35 EST 2016: mmchnode: Processing node sym3
mmchnode: Node sym3 does not have a GPFS server license designation.
mmchnode: Command failed. Examine previous error messages to determine cause.

Hi Kevin,Thanks for the response, but that page is still not helpful.We will not be exporting any data from the GPFS cluster through the AFM gateways. Data will be coming from external NFS data sources, through the gateway nodes INTO the GPFS file systems.Reading that licensing page suggests a client license is acceptable in this situation. There is no mention of AFM explicitly as a function of the server license.Cheers,Luke.On Thu, 10 Nov 2016 at 14:20 Kevin D Johnson <[email protected]> wrote:An AFM gateway node would definitely be a server licensed node.

Thanks for the feature matrix, but it doesn't really say anything about client / server licenses. Surely you can have clients and servers in all three flavours - Express, Standard and Advanced.On Thu, 10 Nov 2016 at 12:07 Andrew Beattie <[email protected]> wrote:I think you will find that AFM in any flavor is a function of the Server license, not a client license.i've always found this to be a pretty good guide, although you now need to add Transparent Cloud Tiering into the bottom columnAndrew BeattieSoftware Defined Storage - IT SpecialistPhone: 614-2133-7927E-mail: [email protected]----- Original message -----

HI All,I have a tantalisingly interesting question about licensing...When installing a couple of AFM gateway nodes into a cluster for data migration, where the AFM filesets will only ever be local-updates, those nodes should just require a client license, right? No GPFS data will leave through those nodes, so I can't see any valid argument for them being server licensed.Anyone want to disagree?Cheers,Luke._______________________________________________
