varyoffvg Command

Edit online

Purpose

Deactivates a volume group.

Syntax

varyoffvg [ -s ] VolumeGroup

Description

The varyoffvg command deactivates the volume group specified by the VolumeGroup parameter along with its associated logical volumes. The logical volumes first must be closed. For example, if the logical volume contains a file system, it must be unmounted.

To activate the volume group, use the varyonvg command.

Note: To use this command, you must either have root user authority or be a member of the system group.

You can use the System Management Interface Tool (SMIT) to run this command. To use SMIT, enter:

smit varyoffvg
Notes:
  • A volume group that has a paging space volume on it cannot be varied off while the paging space is active. Before you deactivate a volume group with an active paging space volume, ensure that the paging space is not activated automatically at system initialization, and then reboot the system.
  • The varyoffvg command discards any background space reclamation process that is running for the volume group. To identify whether a space reclamation is running, you can use the lvmstat command with -r option.

Flag
