The effective configuration has changed to SWITCHB_CONFIG Next disable the effective configuration on the Switch A either from GUI or CLI:Īt this point you can interconnect the switches and you should see the following log entry on Switch A: You can accept all defaults, except for the Domain field:

Switch will ask you a series of questions. If you want to take the CLI path, run the following. Because switch has to be disabled before making the change.įrom the Web Tools go to Switch Administration, disable the switch in the Switch Status section, type in the new Domain ID and re-enable the switch: Bear in mind that even if you’ve picked scenario 3 as the least disruptive approach for merging zones, changing Domain IDs will still be disruptive. First step is to change Domain IDs on the second pair of switches.

Once fabrics are merged, zones from Switch B propagate to Switch A and you can simply combine them in one zone in the GUI, which is just a few mouse clicks. In my case I went with scenario 2 for two reasons: one – it was a DR site where I could temporarily bring down both fabrics and two – I didn’t need to manually add aliases/zones/configs to the switches as I would have to in scenario 3. This is the easiest and least disruptive path if you are worried that disabling effective configuration on the switches may cause issues. That means you MUST have completely identical aliases, zones and configs on Switch A and Switch B. Under this scenario you will have to recreate the same configs on both fabrics.

This is the easiest path and is what Brocade calls a “clean merge”. Scenario 3: Switch A and Switch B have the same defined and effective configuration. If you are still concerned, implement Scenario 3. Outage is not required, because typically you have two redundant fabrics – fabric A and B in each location. You also MUST disable effective zoning configuration on Switch A. If this requirement is not met, fabrics won’t merge and you will end up with two segmented fabrics because of the zoning conflict. If you want to merge such fabrics, you MUST have unique set of aliases, zones and configurations on each fabric. This is the scenario where you have two individual fabrics with their own set of aliases, zones and defined configurations. Scenario 2: Switch A and Switch B have different defined configurations. As a result of the merge configuration from the Switch B propagates to the switch A. This is the most straightforward scenario when you are adding a brand new Switch A to an existing fabric. Scenario 1: Switch A does not have a defined configuration. Switch B has a defined configuration. If you want to get more details, refer to the Brocade Fabric OS Administrator’s Guide and specifically the section called “Zone merging scenarios”. There are at least nine different scenarios, but we’ll touch only on three most common ones. Brocade is very specific on how zoning should be configured for two fabrics to merge. Third, verify that the switches you’re interconnecting have compatible zoning configuration. If you’re merging two redundant fabrics, make sure that the second pair of the switches have Domain IDs set to 2. By default Brocade switches come with the Domain ID set to 1. All switches within the same fabric must have unique IDs. Second, change the default switch Domain IDs. If you need to connect switches over a longer distance, use long wave SFP+ modules, which have maximum distance of 10km. Short wave 8Gb FC transceivers are limited to 190m when using OM4 fibre. I thought I would fill the gap with this post and share my own experience.įirst, make sure you have the right transceivers. There were a few community posts on the Brocade forums, but there seemed to be some confusion around how zoning should be configured to let the switches merge successfully.
BROCADE SAN SWITCH ZONING GUIDE HOW TO
When I was doing a bit of my own research I realised that there is very scarce information on how to do that on the Interwebs. Recently I needed to merge two pairs of Brocade fibre channel fabrics for one of the customers.
