Hi

Where I can find information how can I set-up/confgure diskless client (with HPUX 11.31) on HPUX :),and if is possible setup this env on Integrity Virtual Machines ?Thanks for help

NFS diskless was something you did for workstations a decade ago.
What are you trying to do for a server now? Just use SAN?

DiskLess Clients on HP-UX eneded I thought with 10.2. Only Linux and SOlaris I thought has support for such configurations these days.

The closest thing you can to "diskless" clients (to address costs for local disks and FC/SCSI HBAs) is to use iSCSI Storage + Boot from SAN.

I need to prepare environment to the development purpose, and I need to know how can I configure HPUX 11.31 to boot via nfs (could you answer me if I can use to build this env. on IVM ?Thanks for help

No.
OS on NFS - No.

Well you can try if it works.
Far as I know -- "Diskless Servers (Workstations)" are from the past sir.

Hi,

Think about the I/O for a basic task of the OS core as swap, now imagines it running over a NFS connection, a greatest bottleneck on LAN traffic and poor system performance.

You needs at least a fibre channel connections (gigabit-speed network technology) that connect your diskless box with a SAN (storage area network) solution, here you can done a boot area inside of your SAN.

Rgds.

>what kind of problem is with boot HP-UX via NFS?

This technology was removed years ago.

>could you answer me if I can use to build this env on HPVM?

Yes, since your host must have disks, you can do this on a VM.

Since only modern servers work with 11.31; booting such a server via NFS would not make any sense at all.

I'm still not sure what you really want to achieve.

Regarding virtual machines - these run "on top" of a integrity server running 11.31, so it's not really diskless too.

"diskless" years and years ago means, you have a piece of hardware (like a workstation), that was working via LAN on a "disk" presented from another server. Such thing is no longer sold since many years...

But maybe you mean something like a blade without own disks but booting from SAN?
