Cisco 9506

Question

Hi there

I have a problem with the Cisco 9506.
Look like there is no communication between blades that run's at 2G and those that run at 4G. They way I have tested this, i have created the following zoning:

HBA ---- 2G
SPA Port 0 --- 2G CX-series
SPB Port 0 --- 2G

SPA Port 0 ---- 4G CX4
SPB Port 0 ----- 4G

I do understand that this is not a supported config. But I don't have enough HBA's plus I am busy migrating Data from the CX to CX4. In the above zone I will be able to see LUN's from the CX series. Can't see any LUN's from the CX4. When I move the HBA to 4G port in the blade where CX4 is connected then I can see LUN's from the CX4. If everything is running at 2G, then I can see all the LUN's from both CX, and CX4. Question is: Is there a setting that I need to change to allow communication between the blades (1/2 and 1/2/4 ports)?

Regards,
T

Are you doing port zoning or wwpn zoning ? It looks like you're doing port zoning (sometimes called hard zoning).

Thanks for your help. I am doing wwpn zoning not hard zoning. In my configuration I have got wwpn for the SPA, SPB for the CX4, SPA and SPB for the CX and HBA. I have five entries in one zone.

I did change the speed to 2G instead of auto. But same problem. The problem is communication between the blades.

Ports can communicate between blades if the blades are running at different speeds. That is not the issue. See my previous post.

You should not put in one zone ports from multiple arrays, this is probably your problem. A best practice is even to only have one array port per zone (this is called single initiator single target zoning). But having a single HBA and multiple ports from the SAME array is allowed.

So your zones should look like this:

Zone 1
HBA ---- 2G
SPA Port 0 --- 2G CX-series

Zone 2
HBA ---- 2G
SPB Port 0 --- 2G

Zone 3
HBA ---- 2G
SPA Port 0 ---- 4G CX4

Zone 4
HBA ---- 2G
SPB Port 0 ----- 4G

Create the zones above and activate them, then deactivate the existing zone. This will ensure there is no loss of connectivity as the new zones will already be active.

Hello,I agree with AranH's suggestions. I'd give them a try and let us know the results.Thank you.

Problem solved. We have upgraded the SAN-OS firmware from 3.1.(2) to 3.3.(2). Thanks a lot for your input. Much appreciated.

You should still correct your zoning even though your communication issue was resolved. The way you have zoning set up is not a EMC or Cisco recommended best practice.
