You can RUN the alt_disk_copy COMMAND to copy the CURRENT ROOTVG to an alternate disk. The following EXAMPLE shows how to clone the rootvg to hdisk1: alt_disk_copy -d hdisk1.]

RUN the FOLLOWING COMMAND to DISPLAY information about the logical volume #lv1: lslv lv1.

Run the following command to display information about the logical volume #lv1: lslv lv1.

You can DISPLAY all logical volumes that are part of rootvg by TYPING the following COMMAND: #LSVG -L rootvg/

You can display all logical volumes that are part of rootvg by typing the following command: #lsvg -l rootvg/

To increase the size of the LOGICAL volume REPRESENTED by the lv05 directory by three logical partitions, for EXAMPLE, type extendlv lv05 3.

To increase the size of the logical volume represented by the lv05 directory by three logical partitions, for example, type extendlv lv05 3.

You USE the chvg command to CHANGE the CHARACTERISTICS of a volume group.

You use the chvg command to change the characteristics of a volume group.

Use the following command, where s partition_size SETS the number of MEGABYTES (MB) in each PHYSICAL partition where the partition_size is expressed in units of MB from one through 1,024. (It’s one through 131,072 for AIX 5.3.)

mkvg -y name_of_volume_group -s partition_size list_of_hard_disks

The partition_size variable must be equal to a power of two (for EXAMPLE: one, two, four or eight). The default value for standard and big volume groups is the lowest value to remain within the limitation of 1,016 physical partitions per physical volume. The default value for scalable volume groups is the lowest value to accommodate 2,040 physical partitions per physical volume.

RUN the lsvg COMMAND on the volume GROUP and look at the value for MAX PVs. The value is 32 for normal, 128 for big and 1,024 for SCALABLE volume group.
