vxvol - performing volume tasks

The vxvol command performs Volume Manager tasks on volumes. You can use vxvol to:

initialize a volume
start a volume
stop a volume
establish the read policy for a volume

Starting a volume changes its kernel state from DISABLED or DETACHED to ENABLED. Stopping a volume changes its state from ENABLED or DETACHED to DISABLED (however, it is seldom useful to stop a volume). For more information about volume states, see the "Recovery" chapter in the VERITAS Volume Manager Administrator's Guide.

You can use vxvol to specify one of these read policies:

round reads each plex in turn in "round-robin" fashion for each nonsequential I/O detected. Sequential access causes only one plex to be accessed. This takes advantage of the drive or controller read-ahead caching policies.
prefer reads first from a plex that has been named as the preferred plex.
select chooses a default policy based on plex associations to the volume. If the volume has an enabled striped plex, select defaults to preferring that plex; otherwise, it defaults to round-robin.

For detailed information about how to use vxvol, refer to the vxvol(1M) manual page.
