Keep HP-UX10.20 while installing HP-UX11i

[David Junyent]

Hi,
I have a mirrored vg00 on a server. I would like to keep the current HP-UX version (10.20) on a disk while I install HP-UX11i on the other disk. How can I do it ? (lvreduce/lvsplit...?)

Hi,

"lvreduce -m 0 /dev/vg00/lvol1 /dev/dsk/disk_future11i"

and then repeat for all your vg00 lvols.
Finally, "vgreduce /dev/vg00 /dev/dsk/disk_future11i"

HTH
Kind regards,
Zigor

Hi,

You can do this.

1) Note down the hardware paths of the disks.
2) lvreduce all the lv's from one disk(which is not pri path).
3) vgreduce the disk from vg00.

4) Install 11i and while installing choose the correct disk.
5) Once you complete installation the pri boot path will change to the new
disk.
6) You can boot 11i normally.

If you want to access 10.20 reboot and break the auto boot.
boot from the previous pri path (where 10.20 loaded).

Note: While booting one OS do not access the other OS's disk by vgimport
or vgcreate ..etc.

Hi,

Thanks a lot to all of you. I´m already installing HP-UX11i and I hope to have no need to use my old O.S. (10.20).

Thanks again.
