Keep HP-UX10.20 while installing HP-UX11i

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...?)

I think you're asking can you use one half of your mirror for 11i and the other for 10.20? If so, use lvreduce to free one disk, install onto that disk, and then you can select the OS you wish to boot by selecting the correct disk.

Hi Pete,

Thanks. If I understand, I can do:

lvreduce -m 0 /dev/vg00/lvolx /dev/dsk/one_disk

for all the lvol' s of vg00.

This way, I will have the disk "one_disk" free to install Hp-Ux11i, and the other disk will kepp HP-UX10.20 still installed. Is this correct ?

David --

After doing the lvreduce, you also will want to do a vgreduce to remove the disk from the root VG.

Then install to that disk.

If you dont do the vgreduce then you're 10.20 disk would have trouble booting, because you would have "bad" (not really bad just 11i) lvm information on one of the "10.20" disks in the volume group.

Hi,

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

Thanks again.
