Creating logic
al volumes
Use these comm
ands for logical volume configuration:
lvremove Deletes a logi
cal volume. Any file system at tached to the logical
volume must b
e unmounted before executing the lvremove
command.
Example
lvremove /dev/vgnn/lvolx
lvextend Increases the size of an existing logical volume.
Example
lvextend –L size /dev/vgnn/lvolx
lvreduce Decrease
s the size of an existing logical volume. Any file system
attache
dtothelogicalvolumemustbeunmountedbefore
executing the lvreduce command.
Example
lvreduce –L size /dev/vgnn/lvolx
CAUTION:
Data within the filesystemcanbelostafterexecutionoflvreduce.
Create logical volumes after you create volume groups. A logical volume must be
created for each new SCSI disk device
To create logical volumes:
1. Use the lvcreate –L command to create a logical volume.
Specify the volume size (in megabytes) and the volume group for the new logical
volume. HP-UX assigns the logical volume numbers automatically (lvol1, lvol2,
lvol3). Use the following capacity values for the size parameter:
OPEN-K = 1740
OPEN-3=2344
OPEN-8=7004
OPEN-9=7004
OPEN-E = 13888
OPEN-L = 34756
