Displaying Logical Volume Objects

Displaying Logical Volume Objects

To get a list of the top level XLV objects on a system (volumes, unattached plexes, and unattached volume elements), invoke xlv_mgr and give the command show all, for example:

# xlv_mgr
xlv_mgr> show all
Volume Element: SPARE_VE
Volume:         BIG_VOLUME (complete)

In this example, there are two top level objects, a volume element named SPARE_VE and a logical volume named BIG_VOLUME. The volume element is a top level object because it is not part of (attached to) any plex. Volume elements can be attached to a plex at a later time.

To display the complete hierarchy of a top level object, give the xlv_mgr command show object with the name of the object, for example:

xlv_mgr> show object BIG_VOLUME
VOL BIG_VOLUME (complete)
VE BIG_VOLUME.log.0.0   [active]
        start=0, end=8255, (cat)grp_size=1
        /dev/dsk/dks1d2s15 (8256 blks)
VE BIG_VOLUME.log.1.0   [active]
        start=0, end=8255, (cat)grp_size=1
        /dev/dsk/dks1d3s15 (8256 blks)
VE BIG_VOLUME.log.2.0   [active]
        start=0, end=8255, (cat)grp_size=1
        /dev/dsk/dks1d4s15 (8256 blks)
VE BIG_VOLUME.data.0.0  [active]
        start=0, end=3920223, (cat)grp_size=1
        /dev/dsk/dks1d2s7 (3920224 blks)
VE BIG_VOLUME.data.1.0  [active]
        start=0, end=3920223, (cat)grp_size=1
        /dev/dsk/dks1d3s7 (3920224 blks)
VE BIG_VOLUME.data.2.0  [active]
        start=0, end=3920223, (cat)grp_size=1
        /dev/dsk/dks1d4s7 (3920224 blks)

This output shows that BIG_VOLUME contains log and data subvolumes. Each subvolume has three plexes that have one volume element each.
