10.20 and 11.0 in the same machine

[Angel_15]

I have 10.20 in a B1000 Workstation in a disk.
I have other disk where I want install 11.0 in the same machine.
Anybody knows how i can do it?

[Rajeev Shukla]

You can do that but system will boot from only one OS at a time. Make to disk and load OS 10.20 on one disk and 11.00 on another disk. When systems boots up change the disk you want to boot through. But keep in mind that the machine can still see both the disk and dont mistakingly play with the other disk or import or do pvcreate etc...

Hi,

Note down the hardware paths, and boot 11.00 core and install CD. When asking chose the correct disk. Once you complete installation you have set boot path in PDC (interrupt auto boot) if desired or you boot any OS using
"BO " from PDC.

Best wishes

Yes it is quite possible. I have a D370 which has two internal disks that one has 10.20 and the other 11.00. The only thing you need to do is import any extra volume groups each time, so that any changes that may have been done on the opposite OS is included. Of course you have to boot each time you wish to change to the other OS. As long as you have two disks which are bootable no problem.

[Michael Tully]

Both are root disks but in separate installations. You cannot have both operating systems running at the same time. When you install one, the other is left blank. When installing the second the first disk is to be ignored. Once built and you wish to change to the other OS, you need to boot the system and boot from the opposite partition.

Hi,

yes you can install 11.o on another disk.
confirm the disk which has 10.2(vgdisplay).
while installing 11.0, installation procedure ask you for root disk, here you need to specify the another disk

[Leif Halvarsson_2]

Hi,
The root disk is always the disk you boot from, if booting from the 11.0 disk this is root disk and when booting from the 10.20 disk is root.

How to create a second bootable volume group?

# pvcreate -B -f /dev/rdsk/c0t5d0
# mkdir /dev/vg02
# mknod /dev/vg02/group c 64 0x020000

# mkboot /dev/rdsk/c0t5d0
# mkboot -a "hpux (;0)/stand/vmunix" /dev/rdsk/c0t5d0

# vgcreate -n /dev/vg02 /dev/dsk/c0t5d0

# lvcreate -n lvol1 -L
# lvcreate -n lvol2 -L
# lvcreate -n lvol3 -L
...

# newfs -F /dev/vg02/rlvol1
# newfs -F /dev/vg02/rlvol3
# newfs -F /dev/vg02/rlvol4
...

# lvlnboot -r /dev/vg02/lvol3
# lvlnboot -s /dev/vg02/lvol2
# lvlnboot -d /dev/vg02/lvol2
# lvlnboot -b /dev/vg02/lvol1
# lvlnboot -v

# mkdir root_new
# mkdir stand_new
# mkdir var_new
...

# mount /dev/vg02/lvol1 /stand_new
# mount /dev/vg02/lvol3 /root_new
...

# cd /
# find . -xdev -depht | cpio -pvdlmax /root_new
# cd /stand
# find . -xdev -depht | cpio -pvdlmax /stand_new
...

# vi /root_new/etc/fstab
/dev/vg02/lvol1 /stand hfs defaults 0 0 # new boot LV
/dev/vg02/lvol3 / vxfs delaylog 0 0 # new root LV
/dev/vg02/lvol4 /usr vxfs delaylog 0 0 # new boot LV
...

# vi /stand_new/bootconf
1 /dev/dsk/c0t5d0

# setboot -b
# cd /
# shutdown -r 0

# vgcfgbackup vg02

# vgchange -a n vg00
# vgexport vg00

reboot and breake bootprocess

ISL> hpux -l

# /sbin/vgexport vg02
# /sbin/mkdir /dev/vg00
# /sbin/mknod /dev/vg00/group c 64 0x000000
# /sbin/vgimport vg00 /dev/dsk/c0t5d0
# /sbin/vgchange -a y vg00
# /sbin/mount -a

# vi /etc/fstab

# cd /
# shutdown -r 0

The root disk in the 11.0 installation is the
11.0 disk or 10.20 disk?

[Ravi_8]

Hi,

The root disk in the 11.0 installation is the
11.0 disk or 10.20 disk?

check with vgdisplay while you are in 10.2
another way is while you are running 10.2
SAM--> disk and file systems--> disk devices

In Use column you could see'LVM", that's your 10.2 disk. remaining disk is the empty , note down it's "Hardware Path".
during installation if the root disk is same as noted Hardware path then continue, else press enter while the curser is on root disk.
Select the root disk same as noted Hardware path

[V. Nyga]

Hi Angel,

you have to separate both installations complete.
So root for 11.0 on 11.0-disk and root for 10.2 on 10.2-disk.

I think you are assuming like win98/win2k from same hardisk/partition. Here It cannot be same disk. If you install to same disk you lose the existing OS. Both OS/disks are independant. From one OS you will see other disk as unconfigured(default).

Hello

I am installing HP-UX 11.0 from a CD-ROM and the boot process stop in

Boot
:disk (10/0/14/0.0.0.0.0.0.0;0):INSTALL
6541804+4099600+286144 start oxidf6e8

The process don??t continue.

Anybody knows what happens?

[Armin Feller]

Hi,

exist a HP firmeware on the disk you try to install to?

In my mind it seams that you are trying to install HP-UX to an not supported hard disk.

Regards,
Armin

Hello:

I'm installing 11.0 with a version of November 97 in a B1000 Workstation.
I think this 11.0 vesion is not compatible with the B1000 WorkStation.

Is it true?

[Armin Feller]

Yes, you need a special installation CD:

10.20 ACE4 (min 9906)

ACE (additional core enhancement) for the special hardware in the B1000 system.

Armin
