Questions about Changing Domain ID's on Brocade SAN Switches : 3900 and 4100

Hi, I have a existing setup for 2 fabrics with 2 Brocade switches as part of each fabric. These 2 fabrics are ISLed together. I wanted to change the Domain ID's on these 4 switches during a downtime. When I changed the Domain ID's on the switches, we lost connectivity to all the hosts connected to the switch and none of ports would show the blinking lights on the web interface. The ports all showed steady green lights on the interface. I had to change the Domain ID'd to what they were before to restore connectivity. Can you please let me know the cause for this and also let know the correct procedure to change the Domain ID's on these Brocade. Regards, Leon Pereira

if you are working with Port-Zoning, you have to update your Zone-Configuration after changing the Domain-ID.
If you look in Zone-Admin you can see the Zone-Members are Displayed like this: 1,0 ; 1,1 etc

Now, if you are changing the domain-id from 1 to 2, the name of the ports are 2,0 ; 2,1 ...
Zone Members are still 1,0 ; 1,1 ...

Add the new ports to the zone and delete the old ones, then it should work.

Regard, Stefan

What's the command to check the domainID and what's the command to change the domainID of a joining switch. Say I want to connect a VA-40FC to my DcX core switches on AG mode, do i just run a fc cable and connect it ? i want to make sure ISL works between the 2 switches and no domainID conflict. Thanks for your help..

I agree with stefen V. Before change the domian ID check that zoning were not configured with por-zoning. and also if you change the domian ID it will cause the entre fabric to rebuild agian. This will disturb your newtwork. If that was ok then you can change you domain d

What is the resolution to this issue? This post didn't give any error codes from the SADE GUI, once the Domain ID's were restored. Hard to diagnose without an error response. ZT3000 "Beta tester of "0"s and "1's"

    SADE = Storage Automated Diagnostic

    Brocade switches have a "Webtools" GUI.

    As far as I know, Steady green is the desired state for your ports since it means "Online (connected with device)"

How do I connect to SAN switch with serial cable

If am not mistaking I believe the is an port on the switch for a serial connection. There should have been a serail cable that came with the switch. It should be RJ-45 to RJ-45 and on one end of this cable there should be an RJ-45 to RS232 adapter.
Connect the one end to the switch and the other to the computer, with or without the aforementioned adapter. I do not recall the COM setting needed but you can visit the HP support website for the manuals of your switch. The HP part number you want to search is A7987A. This is basically a Brocade switch under the hood.
Good luck.

MCDATA 4500 firmware

The Sphereon 4500 (ES-4500) line was purchased by Brocade when Brocade acquired McData back in 2007. These SAN switches and others were marketed using an OEM/reseller model and HP was one of them along with others. So, this switch may still be under and support contract with either Brocade or via one of the OEMs or resellers. If that is the case, then the firmware may be downloaded from whomever the support contract is with. I'm sorry if this seems very complicated but I wanted to explain why it might come from HP or from others depending on the relationship the switch came from.

How do i change the configuration from domain to work group

even if you mistakenly joined a domain you can still log in through your existing id and password.
Once your press CTRL+ALT+DEL, you will see a login window with three fields namely: user id, password and Domain.
In the log in screen use the drop-down menu in front of Domain (which shows your new domain- most likey MSHome) and choose 'this computer'. After this, enter your old/existing user id and password and hit enter.
Please proceed to your system settings and change your domain back to Workgroup. Restart PC.

System not detecting the disk array.

Hi there, You apparently don't have downloaded all drivers and software needed. I'd go to: hardware/docs/Network_Storage_Solutions/Adapters/index.html. Install the software in the following sequence: 1. Download and install Sun StorEdge SAN Foundation software 4.2 packages and patches. See Sun StorEdge SAN Foundation Software 4.2 Installation Guide, 817-1244. 2. Download and install the appropriate JNI 2 Gb PCI Single and Dual Port HBAs packages and patches. See JNI 2 Gb PCI Single and Dual Port Fibre Channel Host Bus Adapters Release Notes, 817-2260. Good luck!
