Description
The vxprivutil utility is a command-line tool provided by Veritas for low-level access to the private region of VxVM disks. One of its key functions is the ability to generate a human-readable dump of the configuration database stored on a specific disk.

1. Use vxdisk to get a listing of disk groups, along with the disks that they contain (Figure 1).

Syntax: vxdisk -o alldgs list Example, with typical output: # vxdisk -o alldgs list |
2. Use the "for" script to generate a list of disks that have an "enabled" copy of the configuration (Figure 2).

Syntax:
for i in `vxdisk -o alldgs list | awk '{print $1}'`; do echo $i; vxdisk list $i | grep config | grep enabled; done Example, with typical output: # for i in `vxdisk -o alldgs list | awk '{print $1}'`; do echo $i; vxdisk list $i | grep config | grep enabled; done |
3. Use vxprivutil to dump a copy of the configuration from one of the remaining disks in the disk group that have an "enabled" copy of the configuration (Figure 3).
By default, vxprivutil is located in /etc/vx/diag.d.

Syntax:
vxprivutil dumpconfig /dev/vx/rdmp/ > /directory/filename Example, with typical output:
# /etc/vx/diag.d/vxprivutil dumpconfig /dev/vx/rdmp/ams_wms0_60 > /tmp/ams_wms0_60.cfgrec |
Issue/Introduction
If vxconfigbackup is unavailable, vxprivutil may be used to generate a dump of the private region.
