Need Help! Cisco MDS Software Release for 2-Node MetroCluster

Hi,

 

we're currently building a 2-node streched metrocluster, based on AFF A300 Controllers.

The customre needs a FC Frontend, so Cisco MDS 9148S switches came into place.

 

We have big troubles with this setup, because in case of a metrocluster switchover or switchback, the FC LIFs doesn't come up. They are getting stucked with status:

FDISC error - ID could not be acquired for this virtual port.

 

A manual interface reset on MDS or dis-/enable of affected LIFs will bring the LIF up, but that's not an option.

 

I've raised a ticket at Cisco for this and it looks like, that we hit a couple of bugs. For example this one: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCve72490

 

I know, there are so many Metroclusters with an MDS SAN frontend outside. Can you please provide me your running versions (NX-OS and Ontap)?

 

We're currently running on Ontap 9.1P2 and NX-OS 8.1.1 (recommended by Cisco).

 

 

Thanks!

 

Regards from austria.
