3.New Volume Group을 Create하는 방법  

    1. shell 를 작성하여 일괄로 Vlolume Group 수성하는 방법

   구성: # vi vgcreate.sh

           pvcreate –f /dev/rdsk/c0t5d0

           mkdir /dev/vg01

           mknod /dev/vg01/group c 64 0x010000

           vgcreate /dev/vg01 /dev/dsk/c0t5d0

           lvcreate –l 250 /dev/vg01 : (# lvcreate –L 1000 /dev/vg01 과 같다)

           lvcreate –l 250 /dev/vg01

           newfs -F vxfs /dev/vg01/rlvol1

         newfs –F vxfs /dev/vg01/rlovl2

          :wq

     **  shell 를 구성하지 않고 라인별로 입력하며 확인하여도 됩니다.

      실행 : 위에서 작성한 shell 를 실행 및 disk mount 함.

              # sh vgcreate.sh

              # mkdir /disk1

              # mkdir /disk2

              # vi /etc/fstab 

              # mountall  또는 mount -a

              # vgdisplay -v /dev/vg01로 확인.

              # strings /etc/lvmtab 으로 확인

4.New Lvol을 Create하는 방법  

         # vgdiskplay /dev/vg01

               --- Logical volumes ---
                 LV Name                     /dev/vg01/lvol1
                 LV Status                   available/syncd
                 LV Size (Mbytes)           1000
                 Current LE                  250
                 Allocated PE                250
                 Used PV                     1

              --- Physical volumes ---
                PV Name                     /dev/dsk/c0t8d0
                PV Status                   available
                Total PE                    508
                Free PE                     258

          # lvcreate -l 258 /dev/vg01 또는 ( # lvextend -L 1032 /dev/vg01/lvol1

          # vgdisplay -v /dev/vg01 로 확인

          # newfs -F vxfs /dev/vg01/rlvol12

          # vi /dev/fstab 에 추가

          # mountall (또는 # mount -a )

5. Lvol size를 Extend 하는 방법

        # vgdisplay /dev/vg01

          --- Logical volumes ---
                LV Name                     /dev/vg01/lvol1
                LV Status                   available/syncd
                LV Size (Mbytes)           1000
               Current LE                  250
               Allocated PE                250
               Used PV                     1

        --- Physical volumes ---
               PV Name                     /dev/dsk/c0t8d0
               PV Status                   available
              Total PE                    508
              Free PE                     258

        # umount /dev/vg01/lvol1  또는  #$ umount /mountpoint

        # lvextend -l 508 /dev/vg01/lvol1   또는 ( # lvextend -L 2032 /dev/vg01/lvol1 )

        # vgdisplay -v /dev/vg01 로 확인

        # extendfs -F vxfs /dev/vg01/rlvol1

       # vi /etc/fstab

       # mountall ( 또는 # mount -a )

    다음회에 계속 이어 집니다.
