Hi friends,
Is it possible to export vg00 by booting through lm mode?
My requirement is that i want to change my hard disk and controller id
To my knowledge i will write the steps please correct it
1. boot to single user mode hpux -lm
2.#vgexport /dev/vg00
3.Change the disk or controller id
4.again boot into single usermode (change the pri path)
5.#VGIMPORT /DEV/VG00 /DEV/DSK/C*T*D*
Whether this will work or any correction to be done.
Pls give ur solutions
Thanks in advance

I'd suggest doing this :-

1. Move disc/scsi address etc
2. boot lm mode
3. vgexport /dev/vg00
4. mkdir /dev/vg00
5. mknod /dev/vg00/group c 64 0x000000
6. vgimport /dev/vg00 /dev/dsk/.....

At this point activate vg00 and run lots of lvlnboot commands as it will all be wrong.

Your steps looks good.
After your steps, there're a couple of things to do.

1) lvlnboot -R
2) Modify a file, /stand/bootconf, which has a device file for root volume group with your favorite editor.

Best regards,

I may be missing something, but if you vgexport vg00, in your second boot to single user what would you boot from? You effectively have no operating system on your box.
Have you thought about doing a make_recovery tape, change your scsi id's and then rebuild from the tape?
