OPEN-V = 61432
To calculate S1 for CVS, LUSE, and CVS LUSE volumes, first use the vgdisplay
command to display the physical extent size (PE Size) and usable number of
physical extents (Free PE) for the volume. Calculate the maximum size value (in
MB) as follows:
S1=(PESize)×(FreePE)
Logical volumes can span multiple physical volumes. Use the diskinfo command
for extended LUNs.
2. Create an OPEN-3 logical volume the size of the physical volume, using 2344 for
the size parameter. An O PEN-9 volume uses 7040 for the size parameter to create
a logical volume the size of the physical volume.
Example
# lvcreate –L 2344 /dev/vg06
Logical volu
me "/dev/vg06/lvol1" has been successfully created with
character device "/dev/vg06/rlvol1".
Logical volume "/dev/vg06/lvol1" has been successfully extended.
Volume Grou
p configuration for /dev/vg06 has been saved in
/etc/1vmconf/vg06.conf.
3. Use the lvdisplay command to verify that the logical volume was created correctly.
Example
# lvdispl
ay /dev/vg06/lvol1
- - - Logical volume---

4. Repeat above steps for each logical volume to be created.
You can create only one logical volume at a time. However, you can verify multiple
logical volumes at a time.
