Volume Manager Commands
vxdctl - managing the vxconfigd Daemon
vxdctl - managing the vxconfigd Daemon
The volume configuration daemon (vxconfigd) is the interface between
the Volume Manager commands and the kernel device drivers. The
vxdctl command is the interface to vxconfigd.
vxdctl is used for:
• performing tasks related to the state of the vxconfigd daemon
• managing boot information and Volume Manager root configuration
initialization
• manipulating the contents of the volboot file that contains a list of
disks containing root configuration databases (this is not normally
necessary, as Volume Manager automatically locates all disks on the
system)
• reconfiguring the DMP database (if used on your system) to reflect
new disk devices attached to the system, and removal of any disk
devices from the system
• creating DMP (if used on your system) device nodes in the device
directories /dev/vx/dmp and /dev/vx/rdmp
• reflecting the change in path type into the DMP database for
active/passive disk arrays. You can change the path type from
primary to secondary and vice-versa through the utilities provided by
disk array vendors
The config device is a special device file created by the Volume
Manager that interacts with vxdctl to make system configuration
changes. Some vxdctl tasks involve modifications to the volboot file
that indicates the location of some root configuration copies.
For detailed information about how to use vxdctl, refer to the
vxdctl(1M) manual page.
