[gpfsug-discuss] Am I a gateway or not?

[Abhishek Dave]

Hi John,

I would recommend running 'mmlscluster' command on any cluster node to
check if any AFM Gateway Node(s) is available.

This will list hostname(s) which are running as AFM Gateway.

/usr/lpp/mmfs/bin/mmlscluster | grep -w gateway | awk '{print $4}'

e.g.

~bash# /usr/lpp/mmfs/bin/mmlscluster | grep -w gateway | awk '{print $4}'
node1
node2

Thanks,
Abhishek, Dave

Firstly, I hope everyone at the Manchester meeting is enjoying it and that
the snow did not hamper too many travel plans.
I like Manchester – I shall tell the tale of blowing the 100Amp fuse in the
University server room some other time.
(Yes – a fuse. Not a circuit breaker).

I am writing some monitoring scripts for AFM – actually to interface with
Bright.
I would like the script to detect if the node which is running it is a
Gateway node or has the AFM component.
If not, the script silently exits.
This is not a Callback script – I can write these and indeed have one for
the AFM fileset demount event.

In order to determine which components are on a given node I could:
   a.	Run “mmhealth node show” and grep for AFM
   b.	Run mmlscluster and grep for $HOSTNAME

Both methods seem slightly inelegant. IS there a handy-dandy command I can
run to see the components on this node?
