Library of logical volume subroutines
LVM subroutines define and maintain the logical and physical volumes of a volume group.
System management commands use these subroutines to perform system management for the logical and physical volumes of a system. The programming interface for the library of LVM subroutines is available to provide alternatives to or expand the function of the system management commands for logical volumes.
Note: The LVM subroutines use the sysconfig system call, which
requires root user authority, to query and update kernel data structures
describing a volume group. You must have root user authority to use
the services of the LVM subroutine library.
The following services are available:
| Services | Description |
|---|---|
| lvm_querylv | Queries a logical volume and returns all pertinent information. |
| lvm_querypv | Queries a physical volume and returns all pertinent information. |
| lvm_queryvg | Queries a volume group and returns pertinent information. |
| lvm_queryvgs | Queries the volume groups of the system and returns information for groups that are varied online. |
