HPUX11 and HPUX 11iver2

[Scott_14]

Hello:

Well, I know HP11 quite well, however over the years and changes to jobs I have been supporting other Unix systems with only 1 HP11 system.
I am going to be getting in another HP system
however its going to be on 11i ver2.

How much of a difference is there betwen the old HPUX11 and this HPUX11iver2?

Is there some documents that someone can point me to so I can get up to speed on installing and setting this up?

thanks
scott

Start at: http://docs.hp.com

From there you can select you HP-UX version and find the installation documents.

Is there a difference from the way the file systems work as well?

Hi (again) Scott:

> Is there a difference from the way the file systems work as well?

Well, VxFS 4.1 is now the standard version for 11.23. You cannot mount version-3 file layouts with it, but you can upgrade those versions.

VxFS 4.1 brings a number of enhancements.

Thanks James:

I am so used to 11 where I think I am going to look for a book to see the comparisions as well, so I can at least set up the system and get the drives mirrored.

IS Sam around in ver2?

I know from 11 using extendfs/pvcreate
vgextend as well as other items such as kmtune, which if I recall correctly was new in 11.

Well Scott, mainly HP-UX 11.00 and 11.23 (aka 11iv2) are mainly the same :
SAM is still there (only a few screens have been modified or replaced or behave differently), just like LVM and it's commands, serviceguard, swinstall, ignite ...
Everything you used to do on 11.00 is still available on 11.23, except maybe some minor differences.
The main thing is that 11.23 has additional functionality, new options, new commands, new possibilities of doing things, newer software versions with also added functionality ...
So if you know your way around in HP-UX 11.00, you will find your way in 11.23, but before attempting to set something up as you used to do in HP-UW 11.00, take a look at the new features and functions and maybe you will find a much better way.

Its still good to know all the good people I used to interact with here some time ago are still very much active. My thanks to you
as usual for fast response and information.

Wim thanks for your imput, I was quite concerned that 11 and 11iver2 was so differnent i was going to have to crash learn it, and not just adapt to it.

From the documentation it does seem a bit different on the install, from 11. I used to be in a heavy HP area, which lead me to get my HP Cert, however so much has changed and now my enviroment is not as heavy HP, actually 1 hp11, so going to a new version I was hearing a lot of changes.

thanks

Hi Scott:

Yes, but much of it links outward to standalone utilities. The System Management Home (SMH) is replacing SAM longer term but SAM is still there in 11.23:

In 11.11 it was 'kmtune'. In 11.23 and later it's 'kctune' and it's better. The manpages are your friend!

You will find this whitepaper very informative, too:

http://docs.hp.com/en/7779/commonMisconfig.pdf

The buffer cache is better managed in 11.23 then in 11.11.

Here's some info I got from: Friday, 11 June 2004

11i V2 is the next release of 11i, coming initially for Itanium servers only. A PA Risc processor version will be released late this year called 11.23PI.

It appears HP has changed the way we handle the kernel with this release. The core kernel is basically a frozen piece of code. Configurations are created that are applied at boot up or on the fly. Multiple configurations can exist at the same time. Many "tunables" are now dynamic, some even becoming more or less part of the kernel, so they do not need to be changed. The OS manages these parameters automatically. Some drivers can be added and removed on the fly, like CDFS file system. I expect V3 will add even more DLKM products.

Management of HP-UX is also changing. SAM functionality is reduced in this release as new web based tools are taking over these functions. It is expected that SAM will eventually be completely removed. kcweb is the tool used for tuning the kernel. pdweb manages periferal devices and SPB (software package builder). SCM or HP Systems Insight Manager becomes a major component of system administration. parmgr is the tool used for partition management. All have both GUI and command line interfaces.

Presently, when you boot a PA Risc system, you interact with the PDC, BCH and ISL. A new layered boot tool allows for standardization when booting different platforms. An EFI boot services layer sits on top of a SAL (system abstraction layer) which sits on top of a PAL (processor abstraction layer) which talks to the microcode.

Disk layout changes may not directly impact you, but are something you need to be aware of. Besides the LIF, ISL and HP-UX areas there is now a MBR (master boot record. not used), a Partition Table (duplicated at end of disk), an EFI partition and a HP Service Partition. The ISL is no longer used and is now part of the HP-UX area for compatibility reasons.

When you cold install a system, you can choose a security level. Bastille is part of the OS and is run at install time. There are 4 options you can choose from when you install. These are Security Tool Infrastructure installation only, Host-based lockdown, DMZ Manager lockdown or Full DMZ lockdown.

The customer class also covers n-Par information and commands.

Several library changes happening may be of interest to programmers and application administrators. New aC++ support libraries, enhanced math libraries and more.

CDE is being deprecated. It runs through the Aries PA compatibility application and will not be migrated to native mode IA.

Others: Compressed Crash Dump, IPv6, WBEM, OLAR improvements, MxN thread support, lazy loading, Adaptive Address Space (SAS) to ease porting to HP-UX. and more.

---------------------------------------

Course the current release is 11iv3 (11.31) which offers a bunch more improvements, especially around performance.

Again thanks for all the fast
information and for answering some key questions as well as suppling me with some very good information and links.
