LVM操作在HP-UX和AIX上的区别

    1. 察看当前有哪些VG

        a. 在HP-UX上察看

            1) 通过命令察看

            #vgdisplay

#vgdisplay
--- Volume groups ---
VG Name                     /dev/vg00
VG Write Access             read/write    
VG Status                   available                
Max LV                      255   
Cur LV                      11    
Open LV                     11    
Max PV                      16    
Cur PV                      2     
Act PV                      2     
Max PE per PV               4384        
VGDA                        4  
PE Size (Mbytes)            32             
Total PE                    8748   
Alloc PE                    4178   
Free PE                     4570   
Total PVG                   0       
Total Spare PVs             0             
Total Spare PVs in use      0                    

vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "/dev/oradzgl".

            注：最后两行表示/dev/oradzgl这个VG没有激活

            2) 通过文件察看

            #strings /etc/lvmtab

#strings /etc/lvmtab
/dev/vg00
/dev/dsk/c7t0d0
/dev/dsk/c7t1d0
/dev/oradzgl
/dev/dsk/c16t0d0
/dev/dsk/c16t0d1
/dev/dsk/c16t0d2
/dev/dsk/c16t0d3
/dev/dsk/c18t0d0
/dev/dsk/c18t0d1
/dev/dsk/c18t0d2
/dev/dsk/c18t0d

 

        b. 在AIX上察看

            1) 通过命令察看

            #lsvg

#lsvg
rootvg

 

 

    2. 激活VG/去激活VG

        a. 在HP-UX上察看

            1) 激活VG

            #vgchange -a y VG_NAME

            2) 去激活VG

            #vgchange -a n VG_NAME

 

        b. 在AIX上察看

            1) 激活VG

            #varyonvg VG_NAME

            2) 去激活VG

            #varyoffvg VG_NAME

 

 

    3. 察看VG中包含那些PV

        a. 在HP-UX上察看

        #strings /etc/lvmtab

#strings /etc/lvmtab
/dev/vg00
/dev/dsk/c7t0d0
/dev/dsk/c7t1d0
/dev/oradzgl
/dev/dsk/c16t0d0
/dev/dsk/c16t0d1
/dev/dsk/c16t0d2
/dev/dsk/c16t0d3
/dev/dsk/c18t0d0
/dev/dsk/c18t0d1
/dev/dsk/c18t0d2
/dev/dsk/c18t0d

 

        b. 在AIX上察看

        #lsvg -p VG_NAME

#lsvg -p rootvg
rootvg:
PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
hdisk0            active            546         341         69..00..54..109..109
hdisk1            active            546         345         28..33..66..109..109

 

 

    4. 察看VG中包含那些LV

        a. 在HP-UX上察看

        #ll /dev/VG_NAME

ll /dev/oradzgl
total 0

        b. 在AIX上察看

        #lsvg -l VG_NAME

lsvg -l rootvg
rootvg:
