We are using Trident CSI to provision LUNs from NetApp ONTAP FC. Trident automatically creates individual igroups per node to manage FC initiators.

To attach an existing LUN (not managed by Trident) for passthrough purposes, I manually created an igroup that included all node WWPNs. After this, I observed the following behavior:

On rebooting a node, the Trident-created igroup for that node disappeared from ONTAP.

We are also facing the similar issue. When trident igroup is mixed with igrouop created for our other Luns , then post Reboot trident igroup is getting deleted

#

Do you have any guidance that we should not mix with trident CSI with our own igroup @sinful raven . Pls share your thoughts

I never encountered those issues myself that's why I asked for the version. This sounds like a bug, have you tried filing an issue on GitHub?
