padmin 环境下建立 vdev
先察看以下 vhost 的虚拟 scsi 卡对应各个微分区是否如设计
[ss55aa01][padmin][/home/padmin]#lsmap -all|grep vhost
vhost0 U9133.55A.069511H-V2-C111 0x00000000
vhost1 U9133.55A.069511H-V2-C112 0x00000000
vhost2 U9133.55A.069511H-V2-C121 0x00000000
...
vhost17 U9133.55A.069511H-V2-C192 0x00000000
vhost18 U9133.55A.069511H-V2-C201 0x00000000
vhost19 U9133.55A.069511H-V2-C202 0x00000000
建立各个虚拟存储设备，将微分区 rootvg 映射到各个预先建立的 lv 上，如对于 ss55aa11 这个微分区，建立一个 rootvg1_55a11 将 55a11_rootvg1 这个 lv 映射到 vhost0 上，即 ss55aa11 上的一块 scsi 卡上，从而使得 ss55aa11 这个微分区能认出这块虚拟磁盘来。
mkvdev -vdev rootvg1_55a11 -vadapter vhost0 -dev 55a11_rootvg1
mkvdev -vdev rootvg1_55a12 -vadapter vhost2 -dev 55a12_rootvg1
mkvdev -vdev rootvg1_55a13 -vadapter vhost4 -dev 55a13_rootvg1
mkvdev -vdev rootvg1_55a14 -vadapter vhost6 -dev 55a14_rootvg1
mkvdev -vdev rootvg1_55a15 -vadapter vhost8 -dev 55a15_rootvg1
mkvdev -vdev rootvg1_55a16 -vadapter vhost10 -dev 55a16_rootvg1
mkvdev -vdev rootvg1_55a17 -vadapter vhost12 -dev 55a17_rootvg1
mkvdev -vdev rootvg1_55a18 -vadapter vhost14 -dev 55a18_rootvg1
...

mkvdev -vdev rootvg2_55a15 -vadapter vhost9 -dev 55a15_rootvg2
mkvdev -vdev rootvg2_55a16 -vadapter vhost11 -dev 55a16_rootvg2

mkvdev -vdev rootvg2_55a19 -vadapter vhost17 -dev 55a19_rootvg2
mkvdev -vdev rootvg2_55a20 -vadapter vhost19 -dev 55a20_rootvg2
建立 datavg
同理，建立各个微分区的 datavg，但这里使用磁盘直接对应的，而非 lv，但命令使用方法并无不同：
mkvdev -vdev hdisk3 -vadapter vhost0 -dev 55a11_datavg1
mkvdev -vdev hdisk4 -vadapter vhost2 -dev 55a12_datavg1
mkvdev -vdev hdisk5 -vadapter vhost4 -dev 55a13_datavg1
mkvdev -vdev hdisk6 -vadapter vhost6 -dev 55a14_datavg1
mkvdev -vdev hdisk7 -vadapter vhost8 -dev 55a15_datavg1
mkvdev -vdev hdisk8 -vadapter vhost10 -dev 55a16_datavg1
mkvdev -vdev hdisk9 -vadapter vhost12 -dev 55a17_datavg1
mkvdev -vdev hdisk10 -vadapter vhost14 -dev 55a18_datavg1
mkvdev -vdev hdisk11 -vadapter vhost16 -dev 55a19_datavg1
mkvdev -vdev hdisk12 -vadapter vhost18 -dev 55a20_datavg1
注意 :tempvg 没有加以处理，分配方法一致，留待以后分配
检查一下结果：
[ss55aa01][padmin][/home/padmin]#lsmap -all

至此，每个微分区的 rootvg，datavg 已映射完成。
