as far as cabling a lot has been moved around but the initial setup
was all the top FC connections on the back of the 3par controllers got connected to the 1st cisco switch
then the bottoms were connected to the 2nd.
how is that not good?
the PDF along with my text diagram has the nodes that are connected and talking to specific ports
I didn’t make sense out of the PDF. Anyways, for cabling the 3PAR… if port 3:0:2 was to go down, the persistent port feature on the 3PAR will move the port WWN to the partner port (being 2:0:2) which isn’t in the same fabric resulting in path failure. Also port are not equally distributed resulting in potentially interestimg numbers of paths for each fabric (and hosts) which again could result in interesting performance issues.
As for the rest I can only provide you with what you need to do as you’re not providing me the information…..
1. collect WWNs from hosts
2. verify that those WWNs are visible in FC switch name server (if they are not, there is a host issue or VC issue)
3. verify that those WWNs are seen by 3PAR (check showhost -d . If you don’t find the WWNs visible on a port, you need to check zoming)
If all these 3 things add up, then you start looking at the 3PAR, ensuring that the correct WWNs are mapped to the correct host with the correct persona and that your volumes are exported to the correct hosts.
