Unix Study之--AIX刪除卷組中物理卷

系統環境：

   操作系統： AIX 5300-08

案例分析：

刪除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

通過smit刪除：
[root@aix195: /]$ smit reducevg

出現以下錯誤提示：
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.

通過reducevg工具刪除：
[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上有邏輯卷

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)?

[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為后來增加的page space，其邏輯卷建立在hdisk2的PV上

關閉paging00、01、02：
[root@aix195: /]$ swapoff /dev/paging00 
[root@aix195: /]$ swapoff /dev/paging01 
[root@aix195: /]$ swapoff /dev/paging02

通過smit刪除paging00、01、02三個邏輯卷

[root@aix195: /]$ lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto  Type
hd6             hdisk0            rootvg        2048MB     1   yes   yes    lv

在通過reducevg刪除卷組的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

刪除成功：
[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
