difference between 11 & 11i

[Sanjeev gupta_2]

Hi
What is differnce between 11 & 11i 10.2 & 11

[Steven E. Protter]

Big Question.

11i v1 is newer, has more dynamic kernel parameters, but still boots kernel off HFS filesystem.

11i v2 is recently released, just about getting stable and lets you boot kernel off vxfs filesystem.

10.20 is obsolete and no longer supported

11.00 is approaching its support end of life date as well.

As the above has said there are loads of links in this forum.

11i v1 & 11i v2 ... not too sure of the major differences?
o I'm told 11i v2 is meant to have even better scaling with CPUs than v1.
o 11i v1 has a 32-bit installable, but I think 11i v2 will not, and will only be available as 64-bit.
o 11i v2 will have mode dynamic kernel modules.

11i v1 & 11.0 are fairly similar, but essentiall very similar as far as day-to-dy sys admin. where 11i v1 does differ from 11.0 is
o Dynamic tunable kernel modules 11i v1 has them 11.0 does not. This should save system boots.
o this is the biggy IMHO... 11i v1 supports nPar & vPar partioning, such that yopu can take an 8-CPU system & divide it up into say 2x 4-CPU systems. 11.0 does not
o re-arranged kernlel/sys/usr threads such that processes could spend more time in kernel rather than swapping in & out of sys & usr. This makes the system more scalable with increasing CPUs.

11.0 and 10.20;
o 11.0 introduced streams into the networking.
o 11.0 was the first 64-bit OS, 10.20 was only 32-bit

Some info on 11iv2:

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.
