Brocade 4Gb SAN Switch in C7000 Enclosure and EVA Conection

[DavidEladio]

Hi, i'm an absolutly newby in all this and after many surveys i decided to ask my doubts to solve them 'cause i found it impossible for me to solve it in my own...

as far as i got i have conected the SAN Switch in the c7000 enclosure to the SAN switches, all lights are green buuuuuuut when i'm going to configure the san sitches and it 'looks for' the established connections to be confighured it doesn't detect anything incoming from the enclosure... ¿Do i need to enable anything else?

If i run islshow in the san enclosure switches i get

17 ->
18 ->

please, every help will be very wellcomed... i'm getting desperated with this...

Thank you very much in advance to all you ;)

I gather the C7000 switches are brocade, but what are you connecting them too. Check the port speeds are set to either 4G or auto. Verify that the remote switch can support isl.

[DavidEladio]

The ports are set to 8GB (the switches are licensed to). And i don't know how to check the ISL capability... i need the remote switches to stablish de conection before i configure them caue they can only configure detected connections....

[DavidEladio]

I have 4 Brocade FC Switches in two C7000 enclosures.

Enclosure 1
Switch 13
Switch 14

Enclosure 2
Switch 23
Switch 24

Connected to two remote brocade san switches in a different rack and linked by Fiber.

Rack 2
Switch 81
Switch 91

The interconnections are:

13(port 17) -> 81
13(port 18) -> 91
14(port 17) -> 81
14(port 18) -> 91
23(port 17) -> 81
23(port 18) -> 91
24(port 17) -> 81
24(port 18) -> 91

The remtoe switches (81 and 91) are also connected to two array controllers, a SAN and a management server (windows 2003).

81 -> controller 1
81 -> controller 2
81 -> SAN
81 -> Server

91 -> controller 1
91 -> controller 2
91 -> SAN
91 -> Server

i open a web explorer and go to 10.41.35.81 and get to the management web console, i click in 'configure' and if i select 1 HBA (the server) and 3 ports for storage it recognices all right that four connections and ignore the ones coming from the san switches in the blade enclosures...

as i said, it ignores them but all the lights are green (and blinking slowly).

Please, ask me for all the information you need, i need to get this done and start to feel desperated....


THANK YOU VERY MUCH!

PS: it's my first experience with all this and the documentation i found didn't help me a lot... :(

> blinking slowly

A segmented fabric - the switches cannot merge for _some_ reason (maybe duplicate domain IDs? - run the 'switchshow' command and look for "switchDomain:" - each switch in a fabric must have a unique value).

> 17 ->

Can you copy the full text?

[DavidEladio]

hi there, first of all thank you very much for your interest.

I have prepared some text files with the configuration of the switches so you can see it by yourself. Their names refer to the command (isslshow.txt shows the output of performing islshow comand in the switch).

if you see that it's a mess trying to fix it after several wrong steps and maybe it's easier to reset all them to their original configuration and then confg them i'd also like you to tell me how to reset them 'cause i didn't found that information anywhere....


Thank yuo again, and hope you'll be ablñe to tell me something with this information i give now...

BEST REGARDS!

[AWilliams_1]

The way I read what you have done, is that you have cross connected your switches. In a Fibre Channel world you have redundant and independant fabrics between your hosts and your storage.
You should have connections:
13(port 17) -> 81
13(port 18) -> 81
14(port 17) -> 91
14(port 18) -> 91
23(port 17) -> 81
23(port 18) -> 81
24(port 17) -> 91
24(port 18) -> 91

If you have trunking licences on all your switches then the 2 ISLs from each blade switch (eg 13(port 17) and 13(port 18) will form a trunk to give you increased bandwidth.
Perhaps it would be better to start by only connecting one ISL from each blade switch to the remote switch, and then see how you go.

Is 81 and 91 the domain ID's for the remote switches?.

[DavidEladio]

No, they are not, 81 and 91 are the last octet of their ip address. Their ID's are 1 in both cases.

[DavidEladio]

i connect only port 17 in the first blade san switch (13) to the remote san switch and the light's still blinking in green... i try to config the remote san switch and select 2 HBA and 3 Storage ports... and it detects conection in all the ports except the one coming from the blade san switch... which is represented by a blue dotted line, it´s mostly like if the blade san switch is not sending info... but switchenable has been run... ¿Do i need to do anything else in that blade san switch to enable it and detect its connection in teh remote san switch???

THANK YOU!!!

[Uwe Zessin]

David, you cannot merge two switches with the same domain ID! You have to take one offline with the "switchdisable" command and use the "configure" command to change the domain ID. Put the switch online with "switchenable".

[DavidEladio]

Thanks! but i have now simplified my scheme and i am connecting a blade san switch (a brocade one) to a remote san switch and i found that it's like the blade san switch is not sending signal... i don't know why...

[DavidEladio]

I changed ID Domains and now theire different the situation remains the same i'm afraid...

Anything to solve that blue dooted line?

In in port informaition it sais 'online' and 'E_PORT (Segmentation)(Zone Conflict)'

All the info is in the file i uploaded before...

I'm getting mad with all this!

[Ji Lei]

I agree with Uwe Zessin,
81 and 91 san switch's can't be the same when you connect them together with another individual san swith.

You can test this by just connect the san switches in c7000 to 81, that is:
13(port 17) -> 81
14(port 17) -> 81
23(port 17) -> 81
24(port 17) -> 81

then "switchshow" and "fabricshow" to see it.

BTW:does all the san switches install the Fabric License?

[Ji Lei]

you change which one's domain id ?
show me 81 and 91 switchshow.

Just remind: after you change the Domain ID, you may re-configure the zone.

[DavidEladio]

i configured switch 81 id as 1 and switch 91 id as 3. then i reconfigured zoning in switch 81 which has one link to the blade san switch 13.

switch 13 (port 17) --------> switch 81 (port 12)

That port 12 appears as E_PORT (segmented)(zoning conflict).

Fabric license are present in all switches.

[AWilliams_1]

OK, so you have:
switch 13(port 17) --------> switch 81 (port 12).
Log into Switch 81 and set port 12 to 4G and ensure it has a licence and is enabled.

Log into Switch 13 then do:
Clear all the zone configuration
Configclear
Configenable
Set the domain ID to something other than 1 or 3 eg: 21.
Check that the port 17 is enabled, has a licence, and is set to 4G or auto speed.
reboot


(PS: I cant open the file you attached)

[AWilliams_1]

When you say "remote switch", What is the distance between the switches.
How many fibre attached blades do you have in the c-class chassis. The C-class SAN switches can be purchased with 12 or 24 port licences so you need to be sure that port 17 actually has a licence applied to it.

[DavidEladio]

After doing all that (THANK YOU VERY MUCH!) this is what portshow gives to me:

I re-upload the files so you can check them...

[AWilliams_1]

Hi David,
I just realised that the info I gave earlier was not correct. I had mneant you to clear the zoning configuration of the C7000 SAN switch so the commands should have been:

Cfgclear (will clear all zoning info)
Cfgsave (will overwrite the saved zone info)
reboot

But first remove the isl cable otherwise you might clear the zone info on the remote switch as well.
As your info shows, you have a zoning conflict, so I think the switches are segmenting to protect the 2 zone configs. For them to merge you have to have no zoning info on one or both of the switches.

[DavidEladio]

I'm gonna check that out right now.

Thank you, let me try that and tell you back ;)

[DavidEladio]

AT LEAST.

THANK YOU VERY MUCH!!!!

That was the key, clear the zone config of all the switches so there were no chance to get to a zone conflict.

I did in each conflict:

switchdisable
configure
ID DOMAIN = DIFFERENT DOMAIN IN EACH SWITCH
switchenable
cfgdisable
yes
cfgclear
yes
cfgsave
yes
reboot.

All that with all the fiber wires disconnected from all switches and then i went switching them on one by one and checking all was all right by looking at:

zoneshow
fabricshow
switchshow

And all was connected all right.

THANK YOU VERY MUCH!!!
