Scott, Brocade FOS has had a configuration option called interopmode. This option (up until FOS 7.x) allowed you to define the brocade switch/director to operate in an interoperability mode with McData directors/switches.
The difference between native brocade mode and mcdata mode meant that the domain id for each switch in the fabric is different, depending on the mode. In Brocade mode, when a switch is configured to a domain id of 1, the value actually is 1, in the portid provided to the fcp port, when it does the initial port login (PLOGI) to the switch. In McData mode, this value assigned in the portid is a combination of the domain id offset mode (defaults to x60) plus the domain id specified. The portid assigned is a 3 byte value of the format xxyyzz xx is the domain id of the switch that the port belongs to (in hex) yy is the port # on that switch zz will be 00, for the physical hba that gets logged in. Under NPIV, this will differentiate between the various NPIV systems. FOS 7.0 for brocade directors eliminates the interopmode setting, thus all switches in that fabric must operate in brocade mode. When the change in interopmode is done, the port id value returned will be different. If the port does not support being able to dynamically detect this, and force a new login to obtain the new port id value, then any communication down that port will fail. For example, let's say that the previous interopmode was McData (IM2) and the offset mode is the default, along with the switch/director being configured with a domain id of 1. Then if your fcp connection is connected to port 1 on the switch, your portid value, after the port login, will be 610100 After you change the switch to Brocade mode, the port id will then be 010100 Regards, Peter -----Original Message----- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Scott Rohling Sent: Monday, September 21, 2015 3:46 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: Having issues attaching to LUNs after Brocade mode change Ok - seems there is more to know (working path vs. non-working) - when you said brocade mode change -- it's not clear what that means...
