新建paging space
mkps -n -s 3 datavg
-bash-3.2# mkps -n -s 3 datavg
paging01
-n参数表示馬上激活此页面空间
-s参数指定lp的大小
如果需要在下次系统重启动的时候激活空间则需要加-a参数
-bash-3.2# mkps -a -n -s 4 datavg
paging02
-bash-3.2# lsps -a

paging01 hdisk2 datavg 48MB 4 yes no lv 0
paging00 hdisk2 datavg 32MB 1 yes yes lv 0
hd6 hdisk0 rootvg 512MB 23 yes yes lv 0
