1、在客户端安装EMC host base Agent

mount -F cdfs -o cdcase /dev/dsk/c0t0d0 /cdrom

（只有这样的mount才可以读到正确的emc碟）

swinstall -s /cdrom

2、在EMC Manager Server上建Raid Group(group 3)

3、在Raid Group上建LUN(lun 8)

4、建一个新的Storage Group (js-wap01)

5、在Storage Group (js-wap01)中把js-wap01加入hosts(右键js-wap01-->属性）

6、在Storage Group (js-wap01)中把lun 8加入luns

7、在Hosts（最上面tab）中可以看到js-wap01，打开luns，可看到硬件号为c8t0d0

8、在EMC上做failover，菜单为tools-->failover setup wizard

参数为Configuration Summary
=====================
Host: js_wap01
Initiator Type: HP Auto Trespass
Failover Mode: 0
CommPath: true
Storage System(s):
CK200041400381

如下图：

9、在js-wap01使用ioscan -fnC disk

# ioscan -fnC disk
Class     I H/W Path        Driver   S/W State   H/W Type     Description
===========================================================================
disk      0 0/0/2/0.0.0.0   sdisk    CLAIMED     DEVICE       TEAC    DV-28E-C
                            /dev/dsk/c0t0d0   /dev/rdsk/c0t0d0
disk      1 0/1/1/0.0.0     sdisk    CLAIMED     DEVICE       HP 36.4GMAS3367NC
                            /dev/dsk/c2t0d0   /dev/rdsk/c2t0d0
disk      2 0/1/1/0.1.0     sdisk    CLAIMED     DEVICE       HP 36.4GMAS3367NC
                            /dev/dsk/c2t1d0   /dev/rdsk/c2t1d0
disk      8 0/3/1/0.1.15.0.0.0.0 sdisk    CLAIMED     DEVICE       DGC     CX400WDR5
                            /dev/dsk/c8t0d0   /dev/rdsk/c8t0d0
disk      4 0/3/1/0.1.31.0.0.0.0 sdisk    CLAIMED     DEVICE       DGC     CX400WDR5
                            /dev/dsk/c9t0d0   /dev/rdsk/c9t0d0
disk      6 0/4/1/0.1.15.0.0.0.0 sdisk    CLAIMED     DEVICE       DGC     CX400WDR5
                            /dev/dsk/c10t0d0   /dev/rdsk/c10t0d0
disk      5 0/4/1/0.1.31.0.0.0.0 sdisk    CLAIMED     DEVICE       DGC     CX400WDR5
                            /dev/dsk/c11t0d0   /dev/rdsk/c11t0d0

10、创建物理卷：
#pvcreate  /dev/rdsk/c8t0d0

11、创建卷组
11.1、用卷组名在/dev下创建一目录。
    如果卷组名为vg_miscfile则目录为：/dev/vg_miscfile
    #mkdir /dev/vg_miscfile.
11.2、在此目录下为该卷组创建一组设备文件。
    #mknod  /dev/vg_miscfile/group  c  64  0x010000
12、创建卷组（以物理卷为参数）：
    #vgcreate  /dev/vg_miscfile  /dev/dsk/c8t0d0.
建完后，可以用命令：vgdisplay来检查设置是否正确。

13、创建逻辑卷。
创建逻辑卷时，相应的字符设备和块设备会在卷组目录下生成。
现在，我们在卷组vg_miscfile中创建以下逻辑卷：
一个512MB,名为lv_miscfile的逻辑卷。
#lvcreate -L 512 -n lv_miscfile /dev/vg_miscfile

参数：-L 以MB为单位表示逻辑卷的大小。
-n 指定逻辑卷名称，缺省为：lvol1,lvol2…..。

【hpux】如果涉及多个卷组，最好加上卷组名称比如：

#lvcreate -n lvname vgname

14、創建文件系統。
文件系统建在/dev/vg00/lvoldb01上创建JFS文件系统，如下命令：
#newfs –F vxfs /dev/vg_miscfile/rlv_miscfile

注：一定要有字母r

＃newfs -o largefiles -F vxfs /dev/vg_cdrlog/rlv_cdrlog

创建大文件系统

#fsadm -F vxfs -o largefile /oralce

修改文件系统为大文件系统

15、挂载文件系统。
15.1、创建挂载点：

#mkdir /miscfile

15.2、用mount实现挂载：
#mount -F vxfs /dev/vg_miscfile/lv_miscfile /miscfile。
现在可用bdf显示所有挂起的卷。
16、针对EMC存储做VG的容错处理

# vgextend vg_miscfile /dev/dsk/c10t0d0
Volume group "vg_miscfile" has been successfully extended.
Volume Group configuration for /dev/vg_miscfile has been saved in /etc/lvmconf/vg_miscfile.conf
# vgextend vg_miscfile /dev/dsk/c9t0d0
Current path "/dev/dsk/c10t0d0" is an alternate link, skip.
Volume group "vg_miscfile" has been successfully extended.
Volume Group configuration for /dev/vg_miscfile has been saved in /etc/lvmconf/vg_miscfile.conf
# vgextend vg_miscfile /dev/dsk/c11t0d0
Current path "/dev/dsk/c10t0d0" is an alternate link, skip.
Current path "/dev/dsk/c9t0d0" is an alternate link, skip.
Volume group "vg_miscfile" has been successfully extended.
Volume Group configuration for /dev/vg_miscfile has been saved in /etc/lvmconf/vg_miscfile.conf
# vgdisplay -v /dev/vg_miscfile
--- Volume groups ---

   Autoswitch                  On

16、编辑/etc/fstab文件，以便在机器启动时自动Mount上刚建的文件系统

# cat /etc/fstab
# System /etc/fstab file. Static information about the file systems
# See fstab(4) and sam(1M) for further details on configuring devices.
/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /tmp vxfs delaylog 0 2
/dev/vg00/lvol5 /home vxfs delaylog 0 2
/dev/vg00/lvol6 /opt vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2
/dev/vg00/lvol9 /oracle vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2
/dev/vg_miscfile/lv_miscfile /miscfile vxfs rw,suid,largefiles,delaylog,datainlog 0 2
#

注：EMC配置是出现的错误

在配置EMC时没有做步骤8（8、在EMC上做failover）时出现如下现象：

1、在HP UX上无法扩展VG，实现FailOver

# vgextend vg_miscfile /dev/dsk/c9t0d0
vgextend: Couldn't open physical volume "/dev/dsk/c9t0d0":
I/O error

# pvcreate /dev/dsk/c9t0d0
pvcreate: Couldn't open physical volume "/dev/dsk/c9t0d0":
I/O error
# pvcreate /dev/rdsk/c9t0d0
# vgextend vg_miscfile /dev/dsk/c9t0d0
vgextend: Couldn't open physical volume "/dev/dsk/c9t0d0":
I/O error

说明EMC配置上还没有做Failover功能，HP UX可以通过ioscan看到，但不可控制

# pvcreate /dev/rdsk/c10t0d0
pvcreate: The physical volume already belongs to a volume group
说明c10t0d0为VG中PV的可替换连接，为/dev/rdsk/c8t0d0，也说明了可替换连接是不用pvcreate创建的
