Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

The vxconfigd daemon reads the contents of this file to locate the disks and the
configuration databases for their disk groups.
The /etc/vx/darecs file is also used to store definitions of foreign devices that
are not autoconfigurable. Such entries may be added by using the vxddladm
addforeign command.
See the vxddladm(1M) manual page.
If your system is configured to use Dynamic Multi-Pathing (DMP), you can also
use vxdctl to:
■ Reconfigure the DMP database to include disk devices newly attached to, or
removed from the system.
■ Create DMP device nodes in the /dev/vx/dmp and /dev/vx/rdmp directories.
■ Update the DMP database with changes in path type for active/passive disk
arrays. Use the utilities provided by the disk-array vendor to change the path
type between primary and secondary.
See the vxdctl(1M) manual page.
Backing up and restoring disk group configuration
data
The disk group configuration backup and restoration feature allows you to back
up and restore all configuration data for disk groups, and for VxVM objects such
as volumes that are configured within the disk groups. The vxconfigbackupd
daemon monitors changes to the VxVM configuration and automatically records
any configuration changes that occur. By default, vxconfigbackup stores 5 copies
of the configuration backup and restoration (cbr) data. You can customize the
number of cbr copies, between 1 to 5 copies.
See the vxconfigbackupd(1M) manual page.
VxVM provides the utilities, vxconfigbackup and vxconfigrestore, for backing
up and restoring a VxVM configuration for a disk group.
See the Veritas Volume Manager Troubleshooting Guide.
See the vxconfigbackup(1M) manual page.
See the vxconfigrestore(1M) manual page.
