• Instructions for specifying the units of the report output.

4.9.1. Format Control

Whether you use the pvs, lvs, or vgs command determines the default set of fields displayed and
the sort order. You can control the output of these commands with the following arguments:
• You can change what fields are displayed to something other than the default by using the -o
argument. For example, the following output is the default display for the pvs command (which
displays information about physcial volumes).
# pvs
PV
/dev/sdb1
/dev/sdc1
/dev/sdd1
The following command displays only the physical volume name and size.
# pvs -o pv_name,pv_size
PV
/dev/sdb1
/dev/sdc1
/dev/sdd1
• You can append a field to the output with the plus sign (+), which is used in combination with the -o
argument.
The following example displays the UUID of the physical volume in addition to the default fields.
# pvs -o +pv_uuid
PV
/dev/sdb1
M7iv-6XqA-dqGeXY
/dev/sdc1
XO8M-mcpsVe
/dev/sdd1
dECm-0RZ3-0dGW-tUqkCS
• Adding the -v argument to a command includes some extra fields. For example, the pvs -v
command will display the DevSize and PV UUID fields in addition to the default fields.
# pvs -v
