fcms driver binding

Michal Toth — Wed, 28 Mar 2007 03:47:54 GMT

HI all,

how does the system decide on which fcms driver it will actually use to handle particular HBA. I have just installed new HBA AB378A, have both td and fcd drivers installed on 11.11, however it's the old td that binds with these new adapters, which is not acceptable because this driver limits the link speed to 2GB/s.

many thanks

Michal,
did you create the device file without the -d option on mkfs ?

See "man mksf"

the device file is created automatically:

/dev/td[0-3]

the problem is not with the special file, but with the kernel driver that controls this hardware - e.g. ioscan shows td instead of fcd

Michal,
you could try and change the drivers connected to a device via:
rmsf -H "

"
ioscan -M -H "

"
insf -H "

"

But ensure you have all the info to reset if necessary.

Peter,

the ioscan -M appears to be the way how to solve this. Thanks a lot - i'll give it a try once i get a downtime window.

rgds
