Broken Mirror to boot system and keep system backup

[Pax_1]

Hi,

I have a rp3440 with hpux 11.11 and mirror system. I need some way to broken mirror and keep one copies.

Over primary disk:
I will work on primary hard disk to migrate other system and after this, I will take this disk to put it in other machine and boot there.

Over alternate disk:
The idea is try to keep initial data on alternate disk and be able to boot the original system with the alternate disk.

Excuse my english...

thanks in advance

I would do the following:

1) shutdown the system

2) pull out one of the disks

3) boot the system (quorum mode)

4) run "vgreduce -f vg00"
this will remove the information of the missing disk

5) do your modifications

...

6) shutdown and take out the disk

7) put in the other disk

8) boot in quorum mode

9) insert another disk and proceed just like after replacing a bad disk and restore the mirror

Hi Pax

If you can take ignite backup , you don't want to brake the mirror anyway. If the backup tape is working properly ,
1) shutdown the server
2) remove both hard disks
3) Insert new hard disk
4) Boot from the backup Tape
5) Restore the system.
6) If it is restore properly, again shutdown the server & remove particular hard disk
7) Insert both hard disks into right slots
8) Boot the server.
