四、SDD的配置
1. 检查ESS hdisk是否已正确配置
# lsdev -Cc disk |grep 2105
hdisk2 Available 0E-08-02 IBM FC 2105F20
2. 用smitty dev 配置SDD
#smitty dev

vpath0 Available Data Path Optimizer Pseudo Device Driver |
SDD vpath0成功配置。执行lspv查看pv信息
# lspv
hdisk0 00cd4e8fdfabe0ef rootvg active
hdisk1 00cd4e8fe348149e rootvg active
hdisk2 00cd4e8fa39cf494 datavg
vpath0 none None
3.用hd2vp,将ESS hdisk的volume group 信息转到SDD vpath 设备
# hd2vp datavg
datavg
datavg contains these hdisks and pvids
00cd4e8fa39cf4940000000000000000 hdisk2
hdisk2 is part of vpath0.
Deleting pvid of hdisk2 from ODM database
Create vpath0 pvid of 00cd4e8fa39cf494 in ODM database.
lname=vpath0, pvid=00cd4e8fa39cf494
datavg is converted to dpo device vpathes successfully!
# lspv
hdisk0 00cd4e8fdfabe0ef rootvg active
hdisk1 00cd4e8fe348149e rootvg active
hdisk2 none None
vpath0 00cd4e8fa39cf494 datavg
注:
The fast-path command to remove all Subsystem Device Driver devices from
your system is: rmdev -dl dpo -R
