lvchange | Changes the characteristics
of logical volumes. | vxedit or vxvol set | Creates, removes, and modifies
Volume Manager records. |
| | There is no single equivalent
LVM command. | vxresize | Resizes a file system
and its underlying volume at the same time. |
lvlnboot | Creates root, primary and
secondary swap and dump volumes. It also creates boot areas on the
disk. | vxvmboot (HP-UX 11i Version 1.5 Only) | Prepares volumes to be
root, boot, dump, or primary swap volumes (HP-UX 11i Version 1.5
only). |
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. | | There is no equivalent command
in VxVM. |
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 | Makes a disk an LVM disk. | vxdisksetup | Brings a disk under VxVM control. Example: vxdisksetup c0t3d0 Option 1 in the vxdiskadm menu adds or initializes one or more disks. |
pvdisplay | Displays information about
physical volumes in a volume group. | vxdisk list | 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. |
pvmove | Moves allocated physical
extents from source to destination within a volume group. | vxevac vxsd mv vxdiskadm | Moves volumes off a disk. Performs
volume operations on a subdisk. Moves the contents of old subdisk
onto the new subdisks and replaces old sub disk with the new subdisks
for any associations. The vxdiskadm script presents a menu of possible operations
to the user. Option 7 in the vxdiskadm menu moves volumes. |
pvremove | Removes the LVM header
information and releases the disk from LVM control. | vxdiskunsetup | Removes the VxVM header information
and releases the disk from VxVM control. |
vgcreate | Creates a volume group. | vxdiskadd vxdg init | Creates a new disk group and/or
adds disks to a disk group. |
vgdisplay | Displays information on
all volume groups. | vxdg list vxprint | Displays the contents
of a disk group. Displays information about all objects
or a subset of objects. |
vgchange | Activates or deactivates
one or more volume groups. | vxdg -g diskgroupset activation= mode | Activates a shared disk group. |
vgextend | Extends a volume group
by adding one or more disks to it. | vxdiskadd vxdiskadm | Adds a disk to the disk
group. Option 1 in the vxdiskadm menu adds disks to the disk group. |
vgreduce | Reduces a volume group
by removing one or more disks from it. | vxdg rmdisk vxdisk rm vxdiskadm | Removes disks from a disk group. Removes
the specified disk access record by disk access name. Option
3 in the vxdiskadm menu removes disks. |
vgscan | Scans all disks and looks
for logical volume groups. | vxinfo vxprint vxdiskadm | Displays information about volumes. Displays
complete or partial information from records in VxVM disk group configurations. Option list in the vxdiskadm menu displays disk information. |
vgsync | Synchronizes mirrors that
are stale in one or more logical volumes. | vxrecover | Starts resynchronization
and recovery of volumes. |
vgremove | Removes the definition
of a volume group from the system. | vxdg deport vxdiskadm | Deports a disk group from
the system. Option 9 in the vxdiskadm menu removes a disk group. |
vgexport | Removes a volume group
from the system. | vxdg deport vxdiskadm | Deports a disk group from
the system. Option 9 in the vxdiskadm menu removes a disk group. |
vgimport | Adds a volume group to
the system by scanning physical volumes which have been exported
using vgexport. | vxdg import vxdiskadm | Imports a disk group. Option
8 in the vxdiskadm menu imports a disk group. |
| | No LVM command | vxplex | Operates on plex objects. |
lvchange, lvextend, lvcreate, lvreduce | Performs operations on
logical volumes. | vxvol | Operates on volume objects. |
| | | vxrootmir (HP-UX 11i Version 1.5 Only) | Prepares a disk to support booting (HP-UX
11i Version 1.5 only). |
| | No LVM command | vxsd | Operates on subdisk objects. |
| | No LVM command | vxmend | Fixes simple misconfigurations. |
