Description

There are various 'plex' states in Volume Manager depending upon various conditions that may affect the state of the volume.

One of the state of a Volume Manager plex is the Empty state.  The Empty state of the volume plex indicates that this is the first time association of the plex with a volume object.

The Empty state of a plex indicates that the Volume object is associated to the plex object but has not been initialized. This is the initial state for volumes created by vxmake 

v   testvol       -             DISABLED EMPTY     2097152   ROUND      -         fsgen

pl testvol-01    testvol       DISABLED EMPTY     2097152   CONCAT     -         RW

sd emc0_02a2-01 testvol-01    emc0_02a2 0        2097152   0          emc0_02a2 ENA

This scenario is encountered when a Volume has been newly created using the "vxmake" command or in case where the Volume is not initialized during a recovery operation or a disk group re-build operation.

To enable the plex in EMPTY state and make the Volume in ENABLED ACTIVE state we need to start the Volume by executing the following command:

# vxvol -g testdg start testvol

# vxprint -g testdg -qhtrv testvol

pl testvol-01    testvol       ENABLED ACTIVE    2097152   CONCAT     -         RW

sd emc0_02a2-01 testvol-01    emc0_02a2 0        2097152   0          emc0_02a2 ENA
