lvdisplay(8) System Manager's Manual lvdisplay(8) NAME lvdisplay - Displays information about logical volumes SYNOPSIS /usr/sbin/lvdisplay [-v] LogicalVolumePath ... 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 mi- grated 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 lvdisplay command displays the characteristics and status of each logical volume specified by the LogicalVolumePath parameter. If you use the -v (verbose) option, the program displays physical volume (PV) distribution information, and map information about the physical ex- tents that correspond to the logical extents of the logical volume(s). If you enter the lvdisplay command without any flags, the program dis- plays information about the following characteristics: The name of the logical volume The name of the volume group The access permission: read-only or read-write The state of the logical volume: avail- able/stale, available/syncd, or unavailable Available/stale indicates that the logical volume is available but con- tains physical extents that are not current. Available/syncd indicates that the logical volume is available and synchronized. Unavailable in- dicates that the logical volume is not available for use. The write verify state of the logical volume: on or off The number of physical extents allocated for each logical extent The sequential or parallel scheduling policy The number of logical extents currently in the logi- cal volume The number of physical extents allocated to the logical vol- ume The bad block relocation policy The current allocation state: strict or non-strict A strict allocation specifies that mirror copies for a logical extent are not allocated on the same physical volume. A non-strict allocation specifies that physical extents that belong to the same logical extent can be allocated on the same physical volume. If the allocation does not meet the criteria for strict, it is consid- ered to be non-strict. FLAGS Lists the map and the following additional information about the dis- tribution of the logical volume across the physical volumes of the vol- ume group. Distribution of logical volume: lists the distribution of the logical volume LogicalVolumePath within the volume group: The name of the phys- ical volume to which the logical extents are allocated The number of logical extents that are allocated on the physical volume The number of physical extents that are allocated on the physical volume Logical extents: displays the following information for each logical extent: The logical extent number The physical volume name that corre- sponds to the location of the first physical extent of the logical ex- tent The first physical extent number allocated to the logical extent The status of the first physical extent: stale or current The physical volume name that corresponds to the location of the second physical ex- tent (first copy) of the logical extent The second physical extent num- ber allocated to the logical extent The status of the second physical extent: stale or current The physical volume name that corresponds to the location of the third physical extent (second copy) of the logical extent The third physical extent number allocated to the logical extent The status of the third physical extent: stale or current EXAMPLES To display information about the logical volume, lv03, enter: lvdisplay /dev/vg01/lv03 The program displays information about lv03, its logical and physical extents, and the volume group to which it belongs. To display all the available information about the logical volume, lv03, enter: lvdisplay -v /dev/vg01/lv03 The program displays the characteristics, status and distribution map of lv03.
