VA7400 and Brocade help with configuration

HP came out the other day and installed a 7400 for me. I installed a Brocade switch as well (HP wasn't responsible for this install). They also installed Fibre Channel cards in our N Class servers. The tech directly patched on of the N classes to the 7400 controller and we could do an armdiscover and see that it was there. Now he is gone and I want to use the Brocade so that the other HP boxes can use this 7400. Can anyone help me with a starting point and where to look on how to configure both the 7400 and the Brocade so they can live together?

At this time I have the controller(s) for the 7400 going directly to the Brocade along with the other N Classes but when I go to to do an armdiscover or any other sdm commands, I get nothing. Where do I begin to make this 7400 "sharable"? I made sure that the brocade isn't zoning and it looks like it still has basic "out of the box" configuration. When I look at the ports in the brocade management program, I can see the HPs plugged in! It even has the Part numbers! However, still no communication.

I am obviously missing some basic info. Any would be greatly appreciated.

Thanks,

Mike

You should have the brocade and va7400 manuls, right?

Do you have a lan connection into your brocade?

Re: VA7400 and Brocade help with configuration

I have all the manuals and I have read them. The HP books don't talk "directly" about how to get this equipment to work within a SAN environment and the Brocade books don't talk about how to get a drive array to work within its environment. I have all the pieces, just having a problem putting it together. Trust me...I am digging. Yes I have a LAN and now I have a SAN.

Re: VA7400 and Brocade help with configuration

At this point, I would suggest setting up the Brocade switch on the LAN, follow the instructions to assign to it an IP address and then access the switch with the web interface that is way more friendly than the command line. Then, make sure the switch has fabric login enabled and then play around with zoning the devices and the FC cards.
Good luck,

Mike,

Which Brocade switch do you have? The 2400 and 2800 are pretty darn intelligent and you shouldn't have to do much, if any, configuration to them.

Re: VA7400 and Brocade help with configuration

Mike,

I'm not familiar with the 3800. I do, however, have a Brocade book "Building SANS With Brocade Fabric Switches" that I got for free from the Brocade website (sorry I don't remember the URL). The book suggests troubleshooting with the switchShow command. This is supposed to tell you whether the device is logically connected to the switch. If it is connected, it should show up as an Nx_Port and your next step is to see if the device is present in the Simple Name Server (SNS) using the nsShow command - or you can use the WEB TOOLS GUI.

Hope this helps. I'll see if I can find the URL for the free book offer (though that will take a week or so to get to you).

Darn, Brocade isn't giving away the book anymore. They're now giving away a "Portable SAN Solution Center CD". See:

Re: VA7400 and Brocade help with configuration

When I do a switchshow, the Nclases show up as FPorts and the 2 controllers for the VA show up as LPorts (public).

Re: VA7400 and Brocade help with configuration

Mike,

The book doesn't explain how to interpret the nsShow output, it just says to use it see if the device is present in the Name Server. The rest of the process is supposed to be:
visible in name server?
yes: Is it a zoning issue
no: Node configuration issue?

zoning issue?
yes: Problem identified
no: Timeout or Name Server conflict - escalate

Node Config issue?
yes: Problem identified
no: Name Server conflict - escalate

I'm still studying, trying to work out how you're supposed to interpret this stuff. Keep me posted.

Re: VA7400 and Brocade help with configuration

Mike,

For the zoning question, you use the chgShow command. If the output statest that no configuration is in effect, zoning is not enabled. If zoning is enabled, there may be a zoning conflict which should be readily apparent from the output.

If the device is not in the name server, you can try to reinitialize by using the portDisable and portEnable commands. If the device doesn't register with the Name Server, they suggest you work with your device suppliers.

And that's basically all they have to offer. Hopefully there's something in there that will help you.

No Zoning information is configured. I suppose I am at loss. I will continue to hammer it.

Re: VA7400 and Brocade help with configuration

Mike,

First off, your VA appears to be set for FC/AL mode. Change it to Fabric Login mode. Both ports. You will probably have to use the VFP (serial port) to do this. It should have come with a serial cable for this purpose.

Next, don't connect both of the VA's controllers to the same switch without zoning them apart. (support issue) The simplest thing to do is use 2 switches, which has the added benefit of no single point of failure. If no other switch is available, you can make it work by creating two zones, each with a VA port and one port from each host.

If you have all HP-UX, then leave the host port mode alone. Otherwise, you need to set the host port mode on a per-lun basis.

Next is LUN security. Use CommandView to set which hosts have access to which LUNs.

All the details are in the books. Post more if you have troubles.

Good luck!

Re: VA7400 and Brocade help with configuration

Thanks Pete and Vincent. My problem isn't solved but I am digging more into the manuals and Google searches. A "storage specialist" is scheduled to come out here next week but I wanted to get as much configured on my own and have enough information to formulate questions for him. I did unplug the other controller from the switch and then I connected the serial cable and changed the switch "direct fabric attach topology" per the instruction manual. Still when I do an armdiscover I get nothing.

I apologize for not being a big "point" giver in the past. I have received help from here and the support has been fantastic. I will clean up my point awards as appropriate. There are several questions I have posted where none of the responses have helped but I will still give partial points.

Re: VA7400 and Brocade help with configuration

Mike,

Your last post said you changed the switch to Direct Fabric Attach... I was referring to changing the VA to Fabric mode via the serial port on the back of the VA

I just want to make sure you understand what I meant.

Good luck!

PS: thanks for the points, and your awareness of them. Even unhelpful responses should get 1 point just for trying.

Vincent:

Just to clarify:

I connected a lap top to the VA7400 controller and I did a:

mgr -t 4 -c 1

I have tried that and the default (private loop_ setting:

mgr -t 2 -c 1

Is that what you meant?

Re: VA7400 and Brocade help with configuration

Exactly.

I gather it's still not working...

Hmm... Let's see... switch in fabric mode... VA in fabric mode... no zoning on the switches...

Did you check nsshow to be sure that the VA is now N-port?

Are both the host and VA connected to the same switch? (ie: no real fabric of multiple switches, which should make this easier to figure out)

Does "ioscan -fnC disk" show the VA on the host? Did you remember to "insf -e"?

If you cannot see the VA in the ioscan output and don't get /dev/ files for it, then check LUN Security to make sure no security is set. If you set Security, check that the WWN's you gave for the host are correct.

Let us know how it works out.

Good luck!

Re: VA7400 and Brocade help with configuration

Vincent:

Right - on the brocade when I do an nsshow I get:

Type Pid COS PortName NodeName TTL(sec)
N 011000; 3;50:06:0b:00:00:10:77:0c;50:06:0b:00:00:10:77:0d; na
FC4s: FCP
Fabric Port Name: 20:00:00:60:69:50:0e:d8
N 011100; 3;50:06:0b:00:00:10:77:b4;50:06:0b:00:00:10:77:b5; na
FC4s: FCP
Fabric Port Name: 20:01:00:60:69:50:0e:d8
N 011300; 3;50:06:0b:00:00:15:42:44;50:06:0b:00:00:09:2f:37; na
FC4s: FCP [HP A6189A HP16]
Fabric Port Name: 20:03:00:60:69:50:0e:d8


So as you can see in the last entry above, the brocade sees the A6189A.

No Zoning is configured.

I only have one switch so yes they are all hooked into it.

ioscan -fnC disk shows this:

disk 21 1/0/0/0.1.19.0.0.0.0 sdisk CLAIMED DEVICE HP A6189A
disk 20 1/0/0/0.1.20.39.0.0.0 sdisk NO_HW DEVICE HP A6189A
disk 19 1/0/0/0.8.0.110.0.0.0 sdisk NO_HW DEVICE HP A6189A

That doesn't look right to me but I am not experienced enough to know what to look for.

I will have to read up on LUN Security. Perhaps our hp tech did that.

I am just picking up where he left off with the brocade.

Thanks for the help.

Re: VA7400 and Brocade help with configuration

Wow Vincent!

I did your suggestion of insf -e and after doing that I go this with the armdiscover:
armdiscover

This could take several minutes ...
HP-A6189A /dev/rscsi/c10t0d0 00SG220J0082 MYHOSTNAME.BLAH.BLAH.mil


Wow...much further then what I got. I didn't know about that command and as I said - HP Tech got it up and running before so I didn't think this was necessary. I added the brocade.

THANK YOU!!!!!!!!!!!!!!!!!!!!!

Now I have to figure out where to go from here but I will do that on my own!

THANK YOU ALL.

Re: VA7400 and Brocade help with configuration

You really should zone your brocade switch. If you are new to it. It most likely has a web interface. Default login/password is admin password. You will need to hook up a terminal and set the ip first, and it a network connection or use a crossover cable with a ip in the correct subnet.
