随手贴---光纤硬盘mpxio的问题

Maybe you have know it, I hope it can give you a little of hint.

If you have system with internal FC disk and use SDS or other tool to make
local
mirror, when you enable MPXIO by edit /kernel/drv/scsi_vhci.conf, the kernel
will assign new controller# to HBA and internal FC disk controller. This
will
lead SDS can not mount / and other partition and reset again and again. This
problem is not seen at SCSI internal disk.

I think it is normal. What we shall do is disable mpxio on internal FC
controller. For example, you shall edit /kernel/drv/qlc.conf on V280R
because it
use ISP2200 as FC controller:

Add one line if your local FC disk path is
/pci@8,600000/SUNW,qlc@4/fp@0,0/disk:

name="qlc" parent="/pci@8,600000" unit-address="4" mpxio-disable="yes";

Then 'reboot -- -r',done.

need some detail explain,for the content of the /kernel/drv/qlc.conf is looked like this:#
# Copyright (c) 1999-2000 by Sun Microsystems, Inc.

#
# Qlogic Fibre Channel Adapter driver configuration

#   File is setup as the default parameters for all adapters in the
#   system.
#   If a parameter needs to be changed for a particular adapter,
#   make a copy of the parameter. Then change the hba number
#   (decimal) in the parameter to match the adapter instance number
#   that is displayed during the boot process. Now alter the
#   parameter for the adapter.
#
#   example:
#       Setting hard address of 124 and 125 for adapter
#       instance 3 and 4 respectively.
#
#       Before:
#           hba0-enable-adapter-hard-loop-ID=0;
#
#           hba0-adapter-hard-loop-ID=0;
#
#       After:
#           hba0-enable-adapter-hard-loop-ID=0;
#           hba3-enable-adapter-hard-loop-ID=1;
#           hba4-enable-adapter-hard-loop-ID=1;
#
#           hba0-adapter-hard-loop-ID=0;
#           hba3-adapter-hard-loop-ID=124;
#           hba4-adapter-hard-loop-ID=125;
#

#
# Enable/disable the use adapter hard loop ID address on the fibre
# channel bus.
#    0 = disable, 1 = enabled
hba0-enable-adapter-hard-loop-ID=0;


#
# Adapter hard loop ID address to use on the fibre channel bus.
#    Range: 0 - 125
hba0-adapter-hard-loop-ID=0;


So i don't know where i can add one line for my fc-al device in this file.Would phionix li JJ help me?or give the source for this article?

cd /var/adm
more message | grep pci@8,600000/SUNW,qlc@4/fp@0,0/disk
就能找到

凤凰，问问你的SE，dd克隆的时候是不是也修改这个？
