4.验证
安装完软件后，将之前的磁盘删除掉，重新扫描，确认磁盘使用了HDLM 多路径软件：
删除设备：
rmdev -Rdl fcs0
rmdev -Rdl fcs1
扫描磁盘：
cfgmgr -vl
查看磁盘：
lspv
hdisk0 00c9f4600382e9e2 rootvg active
hdisk1 00c9f460081caed6 rootvg active
hdisk2 none None
hdisk3 none None
lsdev -Cc disk
hdisk0 Available 0C-08-00-4,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 0C-08-00-5,0 16 Bit LVD SCSI Disk Drive
hdisk2 Available 0A-08-02 Hitachi Disk Array (Fibre)
hdisk3 Available 0A-08-02 Hitachi Disk Array (Fibre)
出现：Hitachi Disk Array (Fibre) 表示磁盘使用了HDLM 多路径软件，多路径软件安装成功
验证多路径链路和磁盘详细信息：
/usr/DynamicLinkManager/bin/dlnkmgr view -lu
Product : USP_V
SerialNumber : 0000001
LUs : 2
iLU HDevName OSPathID PathID Status

00001 000001 Online
0000EB hdisk3 00000 000002 Online
00001 000003 Online
KAPL01001-I The HDLM command completed normally. Operation name = view, completion time =
2011/06/01 03:49:57
查看Status 为Online,表示所有链路正常
四.后续配置
1.修改光纤卡配置
修改光纤卡fc_err_recov 属性值(链路出现故障后快速切换策略)
通过lspath 命令查找到磁盘从那个光纤卡上映射过来的，然后对查到的光纤卡属性做修改
lspath
lsattr -El fscsi0
rmdev -Rdl fscsi0
rmdev -Rdl fscsi1
chdev -l fscsi0 -a fc_err_recov=fast_fail
chdev -l fscsi1 -a fc_err_recov=fast_fail
2.修改磁盘属性
查看当前属性：
# lsattr -El hdisk2
修改属性：
修改queue_depth 值,推荐值为8
修改reserve_policy 值为no_reserve
chdev -l hdisk2 -a queue_depth=8 -a reserve_policy=no_reserve
