**Unix Study之--AIX删除卷组中物理卷**

**系统环境：**

**   操作系统： AIX 5300-08**

**案例分析：**

**删除rootvg中的pv（hdisk2):**

**\[root@aix195: /\]$ lsvg -p rootvg**  
rootvg:  
PV\_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION  
hdisk0            active            550         249         109..00..00..30..110  
hdisk2            active            319         260         64..64..04..64..64

**通过smit删除：**  
\[root@aix195: /\]$ smit reducevg  
  
**出现以下错误提示：  
0516-016 ldeletepv: Cannot delete physical volume with allocated  
        partitions. Use either migratepv to move the partitions or  
        reducevg with the -d option to delete the partitions.  
0516-884 reducevg: Unable to remove physical volume hdisk2.  
  
通过reducevg工具删除：  
\[root@aix195: /\]$ reducevg**  
0516-606 reducevg: Volume group name not entered.  
Usage: reducevg \[-d\] \[-f\] VGname PVname...  
Reduces volume group size by removing a physical volume.  
  
**\[root@aix195: /\]$ reducevg -d rootvg hdisk2**

**提示：在hdisk2的pv上有逻辑卷**

0516-914 rmlv: Warning, all data belonging to logical volume  
        **paging00** on physical volume hdisk2 will be destroyed.  
rmlv: Do you wish to continue? y(es) n(o)?

0516-914 rmlv: Warning, all data belonging to logical volume  
        paging01 on physical volume hdisk2 will be destroyed.  
rmlv: Do you wish to continue? y(es) n(o)?   
0516-914 rmlv: Warning, all data belonging to logical volume  
        paging02 on physical volume hdisk2 will be destroyed.

**查看系统页面交换空间：**  
\[root@aix195: /\]$ lsps -a  
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto  Type  
paging02        hdisk2            rootvg        1792MB     1   yes   yes    lv  
paging01        hdisk2            rootvg        1792MB     1   yes   yes    lv  
paging00        hdisk2            rootvg         192MB     1   yes   yes    lv  
hd6             hdisk0            rootvg         320MB     1   yes   yes    lv

**---paging00，01，02为后来增加的page space，其逻辑卷建立在hdisk2的PV上  
  
关闭paging00、01、02：**  
\[root@aix195: /\]$ swapoff /dev/paging00   
\[root@aix195: /\]$ swapoff /dev/paging01   
\[root@aix195: /\]$ swapoff /dev/paging02  
  
**通过smit删除paging00、01、02三个逻辑卷  
  
\[root@aix195: /\]$ lsps -a**  
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto  Type  
hd6             hdisk0            rootvg        2048MB     1   yes   yes    lv  
  
**在通过reducevg删除卷组的PV:**  
\[root@aix195: /\]$ lsvg -p rootvg  
rootvg:  
PV\_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION  
hdisk0            active            550         222         82..00..00..30..110  
hdisk2            active            319         319         64..64..63..64..64  
  
**\[root@aix195: /\]$ reducevg -d rootvg hdisk2**

**删除成功：**  
**\[root@aix195: /\]$ lsvg -p rootvg**
