In the IBM H chassis for example, typically you may use switch module bays 1-4 with internal 1gb nics to the blades. My question is are the switch bays usually mapped statically to the interface card instance number. I know this also may vary on the operating system used, for example - a new installation of rh 6.3 and if all the blade hardware is the same:
Would eth0 be mapped to switch bay1, eth1 mapped to switch bay2 etc.
In Solaris I have always seen the bnx interfaces map the same across blades, cant comment for other o/s's.
Are there any circumstances this changes? for example if the first nic is not functioning could the OS allocate eth1 to switch bay1.
Any experiences of this? (background is we need a script to configure blade interfaces, and need to know if the instance numbers can change).
