Upperbound (-u): This option sets the maximum number of disks for a new allocation. If
you set the allocation policy to superstrict, the upperbound value must be the result of the
stripe width times the number of copies that you want to create.
Execute the following command to create an striped LV:
mklv -C 4 -c 1 -s s -S 8 -t jfs2 -u 4 -y striped_lv data01vg 4 hdisk4 hdisk5
hdisk6 hdisk7
AIX 5.3 implemented a new feature, the
striped column. With this feature, you can extend an
LV in a new set of disks after the current disks where the LV is spread is full.
