Devices are not seen after zoning (MSA1000-DL580-SAN2/8)

[Karthik S S]

Hi,

We have a single controller MSA with two switches (cascaded - 12 ports available to hosts) and 2 * DL580s with 4*FC HBA 2101 each. Pl. check the attached diagram for the connection details. I created a simple zone comprising only 2 FC HBAs from both servers mapping to port 1 and 2 of both the switches. After enabling the configuration I can't see the LUNs and also can't see MSA from ACU. What could be the problem? Pl. help.

Thanks,
Karthik S S

Karthik,
you are using WWNNs (world wide node names). I don't know if that works, I have always used WWPNs (port), which (for your adapters) start with '10:00'.

From your description it sounds like you are misunderstanding how zoning works. You do not 'map' WWNs to switch ports - a device 'logs-in' to the switch and then he knows what is connected.

You rather specify which ports/WWNs are allowed to talk to each other and you must include the MSA1000 controller port in the zone - do a 'switchShow' to find out the WWPN.

If that still does not work, I would try either port-based or entirely WWN-based zoning.

Hi Uwe,

Thanks for that. But even after using Port WWNs it doesn't work :-(

As you guessed it right I am not very familar with zoning.

Thanks,

I have also added MSAs controller's port WWN

Uwe,

After adding the MSA controller's port wwn now the luns are visible only on the first dl580 ..!!

How do I make it visible on the seconf dl580?

-Karthik S S

[Uwe Zessin]

Karthik,
I assume you have both switches linked with an external cable and you see an 'E_port' when you do a 'switchShow' command:

port 15: sw Online E-Port 10:00:00:60:69:51:3a:91 "fcswa2" (downstream)

(don't bother if it says 'upstream' instead)

Can you see the MSA on the second server when you run the ACU there? Do you have SSP (selective storage presentation - also known as LUN masking) enabled on the MSA?

[Karthik S S]

Something wrong ... Now I can't see the MSAs on both of the DL580s.

----------------------------------
Also I have not enabled LUN Masking. If I do a cfgdisable bootcfg then everything will be visible back again. Sorry for bugging you :-(

[Karthik S S]

Also how do I rename these switches from "switch" and "switch2" to some relevant name??

-Karthik S S

[Karthik S S]

Do you mean to say that I need to include these E-Port WWNs also to the zone?

Also I just wanted to be sure that when I say

"1,1;1,2;2,1;2,2"

does it point to ports 1 and 2 of both the switches??

-Karthik S S

[Karthik S S]

I have also added port 0 of switch-1 (1,0) which is connected to the MSA controller to the zone. Sill no luck :-(
