我是靠谱客的博主要减肥可乐，最近开发中收集的这篇文章主要介绍Solaris系统下配置MPXIO，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

用的LSI的存储和普安的存储 SUN V245平台+LPE11002 或者Qlogic QLE2460

环境SUN的V245 +LSI 3994
想测试下 LSI的存储在Solaris下的路径冗余，因为用LSI带的RDAC装完系统就Hang住了……
操作系统环境 SUN-V245 Solaris10 U5  HBA卡是Emulex的 LPE11002 双端口的，先用LSI的Santricity 做了一个Raid
然后在Solaris 下用Format 能看到俩个盘
接着如果使用第三方的存储就如下：
bash-3.00# cat /kernel/drv/scsi_vhci.conf
#
# Copyright 2004 Sun Microsystems, Inc.  All rights reserved.
# Use is subject to license terms.
#
#pragma ident   "@(#)scsi_vhci.conf     1.9     04/08/26 SMI"
#
name="scsi_vhci" class="root";
#
# Load balancing global configuration: setting load-balance="none" will cause
# all I/O to a given device (which supports multipath I/O) to occur via one
# path.  Setting load-balance="round-robin" will cause each path to the device
# to be used in turn.
#
load-balance="round-robin";
#
# Automatic failback configuration
# possible values are auto-failback="enable" or auto-failback="disable"
auto-failback="enable";
#
# For enabling MPxIO support for 3rd party symmetric device need an
# entry similar to following in this file. Just replace the "SUN     SENA"
# part with the Vendor ID/Product ID for the device, exactly as reported by
# Inquiry cmd.
#
# device-type-scsi-options-list =
# "SUN     SENA", "symmetric-option";
#
# symmetric-option = 0x1000000;
如果需要添加别的存储在下面添加如下：

device-type-scsi-options-list =
“DGC     RAID”, “symmetric-option”;

symmetric-option = 0×1000000;

怎么识别Vendor ID/Product ID 了 o(∩_∩)o...
首先执行format，然后选择映射过来的磁盘，选择inquiry 就可以显示了：）如下例所示：
bash-3.00# format

然后呢执行：
bash-3.00# stmsboot -e
WARNING: This operation will require a reboot.
Do you want to continue ? [y/n] (default: y) y
The changes will come into effect after rebooting the system.
Reboot the system now ? [y/n] (default: y) y
This required a reboot, so I rebooted the machine, and low and behold the devices appeared correctly:
重启以后在用format 应该就会只看到一个盘了：）

如果用的是普安的光纤存储的话或者其他光纤存储需要修改另外一些文件
首先用format看到俩个盘
然后在bash-3.00# format

然后修改/kernel/drv/scsi_conf文件
如下所示：bash-3.00# cat /kernel/drv/scsi_vhci.conf
bash-3.00# cat /kernel/drv/scsi_vhci.conf
#
# Copyright 2004 Sun Microsystems, Inc.  All rights reserved.

#

#
load-balance="round-robin";
#
# Automatic failback configuration

auto-failback="enable";
#
# For enabling MPxIO support for 3rd party symmetric device need an
# entry similar to following in this file. Just replace the "SUN     SENA"
# part with the Vendor ID/Product ID for the device, exactly as reported by

#
# device-type-scsi-options-list =
# "SUN     SENA", "symmetric-option";
#
# symmetric-option = 0x1000000;
device-type-scsi-options-list =
"inspur    AS800", "symmetric-option";

symmetric-option = 0x1000000;

在然后看下机器上的光纤设备，我下面显示的还有Qlogic的是因为我插过QLOGIC的卡……
bash-3.00# ls -l /dev/fc
total 10
lrwxrwxrwx   1 root     root          60 Jul 22 12:12 fp0 -> ../../devices/pci@1e,600000/pci@0/pci@8/lpfc@0/fp@0,0:devctl

然后编辑/kernel/drv/fcp.conf文件添加下面的内容

bash-3.00# vi /kernel/drv/fcp.conf
"/kernel/drv/fcp.conf" 8 lines, 182 characters
#
# Copyright 1999 Sun Microsystems, Inc.  All rights reserved.

name="fcp" parent="pci@1e,600000/pci@0/pci@2/lpfc@0,1" instance=0 port=0 mpxio-disable="no";
~
然后保存后执行下面的命令：#stmsboot -e 重启后就可以正确认出来一块盘了

bash-3.00# luxadm probe
