Here’s some useful aix commands fro creating logical volumes and file systems.

mklv -t (type) -y (name) VG ##

    1. Type = jfs, jfslog, or other some such
    2. name = where ## is a one up number for each logical volume
    3. ## is the number of PP’s for the logical volume.

e.g. mklv -t jfs -y vg00.lv31 vg00 8

crfs -v jfs -d DEVICE -m MOUNT_POINT -A yes

    1. -v = filesystem type (normally jfs)
    2. -d = logical volume device file
    3. -m = mount point for new filesystem.
    4. -A = yes or no depending on automounting on boot up.
