Hi

here is how we do it:
1) create a BC lun from parent lun
2) create volumegroup with BCV Lun
3) copy data from parent lun
4) mount lvol from BCV volumegroup
and then you can backup.
you will also need a fsck for mounting.

Hi

First, are you using HPUX or W2K?

What happens is that when you create the BC, a "new" disk is seen by the OS. If you're using secure manager, you must configure the new BC lun in order to be seen by the system responsible by the backup.

Hello!!
Thanks for answer.
I am using HPUX 11.0 and not using secure manager.

2) create volumegroup with BCV Lun
What it is BCV? Business Copy Volume manager ?
How I can create the BCV LUN, tell me command please.
If I must to use LVM command then I create logical volumes some size in parent lun?

Hi,

i create the BC Lun over the Commandview SDM Interface. it's easier to handle. This you can start by exporting display to you're server or workstation , and start with /opt/sanmgr/commandview/client/sbin/launcher
there you have the menu lun management, Business Copy .

the lvm structure should be the same as in the parent lun.

Hi again

After you create the BC lun, you should see it in your system. For that do an ioscan -fnCdisk. If you didn't reboot, you must create the disk device file, ie, insf -e.
Now run again ioscan -fnCdisk, and you should see the device file under the path.

Create a new vg with this disk and make the same lvm structure as the parent lun (identify the parent vg and do a "vgdisplay -v").

After the lvm is done, with the mount points, copy the meta data "armcopy -s bc_lun -a true".

Then start backing up.....
