NAME

pvdisplay - Displays information about one or more physical volumes within a volume group  

SYNOPSIS

/usr/sbin/pvdisplay [-v] PhysicalVolumePath ...  

DESCRIPTION

This command is no longer supported on Digital UNIX systems. Features formerly provided by the Logical Volume Manager (LVM) are now provided by the Logical Storage Manager (LSM). Existing LVM volumes must be migrated to LSM, using an encapsulation process. For information about moving LVM volumes to LSM, see the vollvmencap(8) reference page and the manual Logical Storage Manager.

The pvdisplay command displays information about the physical volume(s) specified with the PhysicalVolumePath parameter. If you use the -v (verbose) flag, the program displays a map of the logical extents that correspond to the physical extents of each physical volume.

If you use the pvdisplay command without any flags, the program displays the characteristics of each physical volume that you specified with the PhysicalVolumePath parameter, namely: The name of the physical volume The name of the volume group The state of the physical volume: available or unavailable The allocation permission for the physical volume The number of volume group descriptors on the physical volume The number of logical volumes using the physical volume The size of physical extents on the volume The total number of physical extents on the physical volume The number of free physical extents on the physical volume The number of physical extents on the physical volume that are allocated to logical volumes The number of physical extents on the physical volume that are not current  

FLAGS

Lists additional information for each logical volume and for each physical extent on the physical volume.
Distribution of physical volume: lists the logical volumes that have extents allocated on PhysicalVolumePath: The name of the logical volume which has extents allocated on PhysicalVolumePath. The number of logical extents within the logical volume that are contained on this physical volume. The number of physical extents within the logical volume that are contained on this physical volume.
Physical extents: displays the following information for each physical extent: The physical extent number. The state of the physical extent: free, current, or stale. The name of the logical volume to which the extent is allocated. The index of the logical extent to which the physical extent is allocated.
 

EXAMPLES

This section contains Digital device-specific examples. To display the status and characteristics of physical volume rz1c, enter: pvdisplay /dev/rz1c To display the status, characteristics, and allocation map of physical volume rz1c, enter: pvdisplay -v /dev/rz1c
