round-robin, use the following command:

# vxvol -g mydg rdpol round vol01

To set the read policy to prefer, use the following command:

# vxvol [-g diskgroup] rdpol prefer volume preferred_plex

For example, to set the policy for vol01 to read preferentially from the plex

vol01-02, use the following command:

# vxvol -g mydg rdpol prefer vol01 vol01-02

To set the read policy to select, use the following command:

# vxvol [-g diskgroup] rdpol select volume

Removing a volume

If a volume is inactive or its contents have been archived, you may no longer need

it. In that case, you can remove the volume and free up the disk space for other

uses.

To remove a volume

Remove all references to the volume by application programs, including

shells, that are running on the system.

If the volume is mounted as a file system, unmount it with the following

command:

# umount /dev/vx/dsk/diskgroup/volume
