Identical FC/FCoE adapter WWN and WWPN on the two nodes in a 2-node netapp simulator cluster

CANTALISE2485 — Thu, 05 Jun 2025 05:29:25 GMT

Hi, guys,

I set up a 2-node netapp cluster-mode cluster using the Netapp OnTAP 8.2.1 Simulator on top of ESXi. Upon finishing setting up the cluster, I used the OnCommand System Manager to check the configurations on the two netapp ontap nodes and found that both nodes have the identical WWN and WWPN for their FC/FCoE adapters. Please see the attached API call output. Well, given that we are reusing the same vmdk file for the second simulator and there's no instruction in the document for updating the HBA adapter settings. Does any one know how to change the WWN and WWPN information on the second simulator node? Any help would be appreciated.

Thanks,

Danjue

Re: Identical FC/FCoE adapter WWN and WWPN on the two nodes in a 2-node netapp simulator cluster

SeanLuce — Wed, 03 Sep 2014 03:45:44 GMT

This is how it is done on a physical system, not sure if it will work on the sim:

1. Access the local node on each head (node run local)
2. Go into diag mode (priv set diag)
3. setflag wafl_metadata_visible 1
4. rdfile /etc/metadir/vdisk/configuration (to make sure the configuration file exists)
5. Force WWN regeneration by removing the configuration file (rm /etc/metadir/vdisk/configuration)
6. Reboot the node (or takeover/giveback)
