Block The block number relative to the physical volume.

Status The current status of the block: free

, used, structure, spared,or

unknown

Offset The offset of the block relative to the logical volume.

LV Name The block device path name of the logical volume to which the block is

allocated.

Display With -l Option

-l is speciﬁed, pvdisplay

displays "LVM_Disk=yes" if the physical volume speciﬁed by pv_path is

under LVM control. If the physical volume is not under LVM control, it displays "LVM_Disk=no" instead.

-u option is speciﬁed along with the

-l option and the disk speciﬁed in pv_path is controlled by LVM,

pvdisplay displays the starting and ending block number of the user data on the disk in 1KB blocks.

If the pv_path is a bootable physical volume,

pvdisplay displays Bootable=yes; otherwise, it

displays

Bootable=no. The format is as follows.

LVM_Disk=yes:Data_Start=

value

:Data_End=value:Bootable=value

The

pvdisplay command returns 1 if any of the physical volumes speciﬁed are under LVM control; oth-

erwise it returns 0.

EXTERNAL INFLUENCES

Environment Variables

to "C" (see environ (5)).

EXAMPLES

Display the status and characteristics of a physical volume:

pvdisplay /dev/dsk/c1t0d0

Display the status, characteristics, and allocation map of a physical volume:

pvdisplay -v /dev/dsk/c2t0d0

Check whether the physical volume belongs to LVM:

pvdisplay -l /dev/dsk/c2t0d0

Check if the physical volume has relocated blocks:

pvdisplay -d /dev/dsk/c2t0d0

WARNINGS

The information about the LVM’s Proactive Polling for alternate links of a physical volume will be

displayed only if the kernel has been updated to support this functionality.
