Upgrade from 10.20 to 11i

[Subhas R. Reddy]

Folks,

I need to upgrade one HP D380 HP-UX 10.20 system to 11i. I am running HP Openview NNM 6.1 on that system. The system has two 180 MHz RISC processors, 1.5 GB RAM and 12GB unused disk space. I have received a set of 11i CDs from HP just a few days ago so I have the current software.

Are the system resources adequate for 11i ? If the answer is yes then which is the best way to do the upgrade without having to reinstall NNM ?

Thanks,

Subhas

Well, the only way you will have success is to install the OS cold (virgin install). Which means that if you have NNM installed in vg00, then you will have to reinstall it. The success rate of "upgrading" "rapidly approaches zero".

Hi Subhas,

See if you can do a cold install. Nevel liked upgrade from 10.20 to 11/11i. Why carry extra baggage when it can be avoided.

D380 Supports both 32/64 Bit 11i.

Here is a thread for your help.

Subhas,
Go with the cold install, upgrades are quite painfull. I've noticed that a swlist on upgraded boxes show 10.20 software in the list sometimes, it just has problems you may want to avoid. You may need to check firmware levels of the D class machine to make sure it can run 64 bit before you try the upgrade. It can handle it if the right firmware level is applied.

Hi,

There has been quite a number of posts in regards
to upgrading 10.20 to 11.x In fact I have only
come across a couple of people who have been
able to do this successfully over the past year.
Each instance has been on a server that very
simple in it's original setup and not much had
actually changed since it's original build(s)
Where I am we have tried around 20 times to an
upgrade on various 'D' and 'K' class servers
all with no success. My advice is do a cold
install where possible and import your volume
groups that are not part of vg00.

Subhas,

Cold install of 11i is the only feasible
choice. Remember, the O/S install is the
key, applications follow later. Regarding
NNM, you can back it up and restore back.
Also, make a copy of any NNM related configuration files in VG00 and restore it
after the 11i install.
