Just came accross with strange problem
In above scenairo I am not able see my blades on WWN on MDS 9148 switch where I can see WWN on Nexus 5548
Please help me to troubleshoot this issue
What are the flogi showing up going over fc 1/29 and 1/30 ?
Your problem is clear: it's a routing issue ? how can a initiator pwwn eg. in VSAN 100 decide, on which port he should go Northbound ?
Create 2 additional VSAN's, e.g. 102 and 103; 100/101 will be used to reach N5k, 102/103 to reach MDS; you of course need 2 additional vhba's, one in 102, resp 103.
Hopefully you have done your zoning with device-alias (enhanced); then this change will be easy.
Another ugly solution would be to use static ping groups, which is hardly used, a management and scalabilty nightmare, and therefore not recommended.
