Network Must restore data to DR server
Hello,

I have posted several threads regarding my voyage of discovery with mksysb's and AIX, but seem to be at a loss now please help me.

I need to restore data from a mksysb to a DR server.
Problem is the DR server only has 2 disks not 4 and no mirrors.

I need to restore AIX 5.2 to the server, I have tried booting from the tape but it hangs before the install text appears,

I have tried to use the sms, the cd and the tape and got no where.
I have tried using wsm and now my latest is cloning the hdisk1 to hdisk0.

Then trying to restore the files from the tape to the new cloned partition, again this is not working, as I ma unaware of how to mount a lv hdisk0 mount point to my hdisk1 /. I was going to use the restore command and extract the directories over the top of each mount point one by one.

Any ideas would be great as I am really stuck, I am a AIX newbie so if you can spell it out it would be great.

I should mention the main error I get using mksysb is

Quote:
# alt_disk_install -i '/var/adm/ras/image.data' -d /dev/rmt0 hdisk0
Restoring /image.data from mksysb image.

physical partitions per disk at a factor value of 16. Specify a larger
Physical Partition Size or a larger factor value in order create a

0516-862 mkvg: Unable to create volume group.
Cleaning up.
I was trying to use the existing image.data file not the one on the disk, also I do not have access to a floppy so that way is out as well.

Any Ideas???

vxdestroy_lvmroot

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
