|
lvcreate
|
Creates a logical volume.
|
vxassist
|
Creates volumes with the make parameter.
Example: vxassist make vol_name 100M layout=stripe
|
lvextend
|
Increases disk space allocated to a logical volume.
|
vxassist
|
Increases a volume in size with the growto or growby parameter.
Example: vxassist growto vol_name 200M,
vxassist growby vol_name 100M
vxassist creates and modifies volumes.
|
lvreduce
|
Decreases disk space allocated to a logical volume.
|
vxassist
|
Decreases a volume in size with the shrinkto or shrinkby parameters.
Example: vxassist shrinkto vol_name 200M
Make sure you shrink the file system before shrinking the volume.
|
lvremove
|
Removes one or more logical volumes from a volume group.
|
vxedit
vxassist
|
Removes volumes with the -rf rm parameters.
Example: vxedit -rf rm vol_name
Removes a volume with the remove volume parameters.
Example: vxassist remove volume vol_name
|
lvsplit
|
Splits a mirrored logical volume into two logical volumes.
|
vxassist snapshot
|
The snapshot operation takes one of the attached temporary mirrors and creates a new volume with the temporary mirror as its one plex.
Example: vxassist snapshot vol_name new_volume
|
lvmerge
|
Reverses and converts the lvsplit logical volumes to a single logical volume.
|
vxassist snapback
|
The snapback operation returns the snapshot plex to the original volume from which it was snapped.
Example: vxassist snapback new_volume
|
lvsync
|
Synchronizes mirrors that are stale in one or more logical volumes.
|
vxrecover
vxvol start
|
The vxrecover command performs resynchronize operations for the volumes, or for volumes residing on the named disks (medianame or the VxVM name for the disk).
Example: vxrecover vol_name media_name
|
pvcreate

|
Brings a disk under VxVM control.
Example: vxdisksetup c0t3d0
Option 1 in the vxdiskadm menu adds or initializes one or more disks.
|
pvdisplay
|

Lists information about VxVM disks.
Example: vxdisk list disk_name
|
pvchange
|
Sets physical volume characteristics to allow/deny allocation of additional physical extents from this disk.
|
vxdisk
vxdisk set
vxedit
|
The vxdisk utility performs basic administrative operations on VxVM disks. Operations include initializing and replacing disks, as well as taking care of some book-keeping necessary for the disk model presented by the Volume Manager.
