Full Discussion: Dd of disk contains vg and restore on another m/c
Operating Systems AIX Dd of disk contains vg and restore on another m/c Post 302855353 by ibmtech on Thursday 19th of September 2013 04:33:31 PM

Why in the world are you using DD? And you are using VG.

Does those LV's have a mount point? Do you have a backup tool? (like TSM, netbackup etc..,)

If your answer is yes then try this,
1st take the snap of vg by running
Code:
mkvgdata  -X -m <vgname>, this will just capture the skeleton of your VG  (that includes your filesystem info and its size

The information is captured under '/tmp/vgdata' directory, look for your vgname directory under that (it will contain files like filesystems vgname.data, loglv.map, etc..,).

Now, goto the destination system where you want to restore the VG
Remember, that you need a disk of same size as it will create the same mapping.
copy the vgdata directory to the destination server and run
Code:
restvg -r -d <location of vgdata/vgname.data file> <hdiskX>

It will recreate all the Logical volumes and also mount the file systems.
Now restore the data from your backup tool.

Second option (say you don't have backup tool) is using savevg to take the entire VG backup
Code:
savevg -i -A -f /<location of backup>, it will be a full backup.

if you use '-r' flag, it wont backup the files in VG (just like mkvgdata command)

Use restore command to restore the VG.

vxconfigbackupd

vxconfigbackupd(1M)													       vxconfigbackupd(1M)

NAME

       vxconfigbackupd - disk group configuration backup daemon

SYNOPSIS

       vxconfigbackupd [-l]

DESCRIPTION

       The vxconfigbackupd daemon automatically backs up information about a disk group's new configuration whenever the configuration is changed.

OPTIONS

       -l	 Logs backup daemon activities to the file /etc/vx/cbr/bkdaemonLog.

FILES

       /sbin/init.d/vxvm-recover
		 Startup file for vxconfigbackupd.

       /etc/vx/cbr/bk/dgname.dgid/dgid.dginfo
		 Location of backup file for disk group information.

       /etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo
		 Location of backup file for disk attributes.

       /etc/vx/cbr/bk/dgname.dgid/dgid.binconfig
		 Location of backup file for binary configuration copy.

       /etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec
		 Location of backup file for configuration records in vxprint -m format.

NOTES

       The vxconfigbackup command can be used to back up a disk group's configuration manually at any desired time.

       The  disk  group  configuration	backup and restore utilities do not save any data in the public region. This includes file system or other
       application data that is configured within VxVM objects.

       When a disk group is destroyed, its configuration backup information (including the backup directory) is also removed.  The only  exception
       to this behavior is when the disk group is in the precommit state of restoration.

       The  backup  directory should be large enough to accommodate copies of all the currently imported disk groups. The minimum recommended size
       of the backup directory is P * (N + 1) megabytes, where P is the private region in megabytes (by default, 32MB), and N  is  the	number	of
       disk  groups. The additional P megabytes is required to hold a temporary copy of the disk group configuration when a disk group is imported
       or a configuration change is made.

       The default backup directory is /etc/vx/cbr/bk.	The location of the backup directory can be configured	by  using  the	vxconfigbackup	-l
       backup_directory_path command.
