I want to change the IDs of Brocade SAN switches (Model 5000, Firmware 6.2.2b) in Dual Fabric. Do I need to stop the AIX servers with RDAC multipath driver and DS4700 Storage System before ?
For the SAN switche. I know I must make a disableswitch / enableswitch.

I'm guessing you want to make a "principal" switch in your fabric ?
This is a non-distruptive process as long as your fabrics are configured correctly , as well as your hosts i.e path managment software.
fabricprincipal -l -f
will make the switch the principal and change all the domain id's for the other switches.

do you want to change the DID = Domain ID ?
if yes,what is the reason for a change ?
when you chnage the DID, you must re-config / re-build the zone/config

I want to change the DID (Domain ID) to connect my Switchs to a fabric. Is it necessary to shutdown the AIX servers and DS47000 Storage System connected to the Switch before updating the DID ? I'm in a Dual Fabric configuration.

We have modified our DID without stop our AIX Servers recently.
We have many Brocade Switches (DCX & 4020 & 4024) and HDS Storage.
For work with AIX, the ODM drivers supply by HDS seems to write the DID in the path of the disks !
Then, when we have changed our DID, we were forced to restart our systems and unconfigure all devices.

In Dual fabric Mode, is not necessary to shutdown the server.
But my question remain,.....
.....what is the reason for Change the DID ?
