HP-UX

There is clearly a typo in the HP directions. In that last step they have changed disks. That can't be right. This procedure should involve only a single disk drive. You too seem to be using 2 disk drives, but you switch drives at a different point than HP. I'm guessing that c0t4d0 is correct and c0t0d0 is wrong. But I'm not sure. You really need to be sure that you're doing everthing to the correct disk. These commands can destroy your system if you run them on the wrong disk.

Also, what hardware are you using? What commands do you use to boot off the second disk? Exactly what result do you get when you try to boot?

Sorry for the confusion; my new disk is in the adress c0t4d0 , I took information from various logs, thats why I have different adresses. I have only 2 disk, one is the original ( this has the operating system), and the new where the copy should be.

The new disk is a SEAGATE ST336607LW ( adress 4 c0t4d0)

The original disk is a :
disk 0 8/0/19/0.6.0 sdisk CLAIMED DEVICE SEAGATE
ST34572WS
/dev/dsk/c0t6d0 /dev/rdsk/c0t6d0

( also I try to do it from a ST336607LW that only have defined 4 gigas of a volume group, it was originally cloned from a ST34572WS , in both cases I fail)

My workstation is an HP Visualize b132L+.

In the halt mode I do :
>SEA
>boot P1 (asuming that the new disk is in P1)

It start booting, then start to load the kernel, then a new screen appears, with a lot information ( something like memory addresses) and then reboots. This happens very fast, so I cant read the errors.

ANdryk: I can boot from my second disk,but it fails loading my kernel.
Thanks

I was thinking maybe instead of use
pvcreate -B /dev/rdsk/c1t6d0

I should define here the size of my volume group, identical of my old disk,something like:

pvcreate -B -s 3906250 /dev/rdsk/c1t6d0
(for a volume group of 4 gigas)
what do you think?

I would newfs the LV's, mount them on temporary mountpoints, and copy the files over. Actually, what I would do is a fresh os install and then copy the non-os files over. And I would install a recent os, not 10.20. Are you sure that 10.20 supports your 36 GB disk?

Do make_recovery bootable backup then restore it back to the 36gb disk.
When doing backup include interactive option (-i) so to resize any filesystem to fit in your 36gb disk when restoring

Thanks I will try it. The make_recovery is an ignite function?
One of my problems is that I dont have Ignite and since 10.20 is not longer supporter is hard to find software for it. Do you know where can I get it? I couldnt find any in the HP web site. I am limited to the 10.20 version because I have an application that only works in 10.20... so I can upgrade
I have 36 gb disk installed with 10.20 I think that it recognized ok.
Any way I did the procedure of volume duplicate limiting the volume size to 8 gigas, it worked fine. But then it booted ok once, but the next time it didnt boot, neither with other disks, that I have already tested.

Finally I could clone it,just defining a max size of 9 gigas for logical volumes. Thanks every body for the help.
