In AIX Version 4.2, or later, if you enter the reorgvg command with the volume group name and no other arguments, it will only reorganize the first logical volume in the volume group. The first logical volume is the one listed by the lsvg -l VolumeName command. 如果reorgvg datavg 后没加任何参数,只能识别vg中的第一个lv,因此A.echo hdisk7|reorgvg -i datavg是正确的。
