一台hp rp8400小型机和一台hp va7110存储系统，小型机的操作系统安装非常正常，
刚开始存储上安装的不是hp原装的光纤硬盘，则在存储上执行dsp -d看硬盘状态时如下：
Not Enough Drives > dsp -d
- DISK AT M/D1:
- Drive State: Unsupported

- Block Size: 520
- Serial Number: 3JA2HDW10000Total capacity of physical disks in array = 66 GB
而正常的存储上看见的信息则如下
- DISK AT M/D14:
- Drive State: Included
- Vendor ID: HP 73.4G
- Product ID: ST373307FC
- Product Revision: HP03
- Capacity: 68096 MB

- Block Size: 520
- Serial Number: 3HZ66GQK
- Recovery Maps are on this disk.
从上面可见不同之处在前两行。
同时在小型机上执行armdiscover时，则有如下报错信息：
- This could take several minutes ...Failed to obtain remote database interface to host: localhost
但是使用ioscan -f |grep A6189B
则可以看见存储信息。
使用armdsp -i时信息如下：
- Error logging in: TIMEOUT EXPIRED
可见小型机上不能对存储进行管理。
没有办法，打电话询问hp 800工程师，则告诉我把硬盘换成hp原装的再给他打电话。
找来找去，两个月过去了，终于找来的hp原装硬盘。
但是上面的问题依然存在。打电话询问hp 800工程师，想了很多办法：如
- /opt/sanmgr/hostagent/sbin/HA_trigger stop
- /opt/sanmgr/hostagent/sbin/dial_trigger stop/opt/sanmgr/hostagent/sbin/HA_trigger start
- /opt/sanmgr/hostagent/sbin/dial_trigger start
重新启动存储管理进程。问题依旧。
在存储上进行个中修改，问题依旧。
如
vfpfmt,mgr -R full 命令等
最后采用在存储上修改主机接口速率，命令如下：
mgr -S 2 -c 2 -hp 1
将存储主机接口修改为2GB（默认1GB），此时看到小型机上的光纤卡的指示灯变化了，（两个灯，一个是电源灯，另外一个是速度指示灯），速度指示灯由黄变绿。
同时采用命令mgr -t 4 -c 2 -hp 1将拓扑结构由原来的Private topology改为Direct fabric attached topology，但是此时在小型机上执行ioscan -f |grep A6189B，什么也看不见，而用户原有通过san交换机连接的存储上的拓扑结构参数就是后者Direct fabric attached topology，可见存储和小型机直接连接不能采用这种拓扑参数，于是将其修改为Private topology，则又可以看见存储了。
但是问题依旧。
最后hp工程师让我修改了一个文件：/etc/opt/sanmgr/hostagent/config/commIpAddr.txt
该文件的内容是192.168.0.200，是我刚装系统时设置的系统IP地址。而现在的ip地址则改为
10.8.32.156，于是修改为现在的ip地址。则armdiscover之后，可以发现存储了。信息如下：
# armdiscover
- This could take several minutes ...
- HP 36.4G-ST336754LC /dev/dsk/c0t6d0 3KQ02WBN00007530 db

- HP 36.4G-MAS3367NC /dev/dsk/c2t6d0 KT043189 0421 db
# armdsp -i
- Product ID: HP-A6189B
- Device Type: Virtual Disk Array
- Alias: hparray
- World Wide Name: 50060b000008abbd
- Unique ID: HPA6189B00SG147G0008
- Serial Number: 00SG147G0008
- Management Path: db:/dev/rscsi/c7t2d0
由此可见存储终于和小型机连接上了。
查看状态,hparray 为 alias[别名]
armdsp -a hparray
划分lun
添加
armcfg -L 0 -a 80g -g 1 hparray
armcfg -L 1 -a 40g -g 1 hparray

创建物理卷：
# pvcreate -f -B /dev/rdsk/c6t0d0
- Physical volume \"/dev/rdsk/c6t0d0\" has been successfully created.
# pvcreate -f -B /dev/rdsk/c6t0d1
- Physical volume \"/dev/rdsk/c6t0d1\" has been successfully created.
#
创建卷组：
mkdir /dev/vg02
mknod /dev/vg02/group c 64 0x010000
vgcreate -s 16 vg02 /dev/dsk/c6t0d0 (这里的16指的是每个pe的尺寸)
如果报错信息如下：
- Increased the number of physical extents per physical volume to 10239.
- vgcreate: Volume group \"/dev/vg02\" could not be created:
- VGRA for the disk is too big for the specified parameters. Increase the
- extent size or decrease max_PVs/max_LVs and try again.
可以通过修改该数字来更改，直到不报错为止。
扩充逻辑卷
vgextend /dev/vg02 /dev/dsk/c6t0d1
划分逻辑卷
lvcreate -L 120000 -n lvarray /dev/vg02
在lv上建立文件系统：
newfs -F vxfs /dev/vg02/rlvarray
修改/etc/fstab文件，以便重启系统后自动挂载文件系统,添加以下内容：
/dev/vg02/lvarray /array vxfs delaylog 0 2 |
