vg's
I need to reinstall my 11.o and 11i systems with 11i Enterprise env.But i do not want to lose the data .So i am planning to do vgexport and vgimport.
Here is my plan
Unmount filesystens then deactivate the VGs
# vgchange -a n /dev/vg1
# vgexport -v -s -m /tmp/vg1.map /dev/vg1
-now reinstall the box
After box is backup and online with new os , use vgimport
# mkdir /dev/vg1
# mknod /dev/vg1/group c 64 0x0?0000
(group minor number will be unique)
# vgimport -v -s -m /tmp/vg1.map /dev/vg1
# vgchange -a y /dev/vg1
# mount -a
any suggesstions ????
Plus do i have to -s option or not ???
I will do this for all the vgs except vg00.

Re: vg's
I thing you are right with your plan, and -s -option is important. If your backup and recover plan is good, I would not have
any troubles.
Rgrds.

Re: vg's
I read the man of "vgexport" it says -s option is for clustered systems but mine is a standalone machine 11.0 and other one 11i -oe so do i need to use that ???

Re: vg's
don't forget to add the filesystems to /etc/fstab lateron. And copy the mapfile to another system!

Jochen

Re: vg's
if you create the mapfile without option "-s" you have to specify the disk yourself by vgimport. If you uses the "-s" option it makes it all more easier. So, if "-s" option works - use it.
Also listen to Jochen, save the etc/fstab to remind the mount points, ... later.

Re: vg's
# vgexport -v -f /tmp/vg1.disk -m /tmp/vg1.map /dev/vg1
and use it also by vgimport:
# vgimport -v -f /tmp/vg1.disk -m /tmp/vg1.map /dev/vg1
Save the .map and .disk file!!!
