SUMMARY: Solaris x86 JumpStart server on SPARC hardware

Hi everybody,

my question:

Do we need a running x86 system to create a JumpStart server on a
SPARC system.

your answer:

yes, it is required.

SPARC processors use "Big-Endian" data encoding, x86 processors
use "Little-Endian" data encoding and UFS is NOT cross-platform.
So we need NFS to compensate these differences.

If we already have a running x86 system, we don't need any CD-ROM,
thanks to lofiadm.

  http://www.bolthole.com/solaris/mount-cdrom.html

tells us how to split the boot ISO image. But we always need a x86
system to mount the ufs part.


Steps to bootstrap a x86 JumpStart server:

1. get one x86 system up and running by hand

2. insert the boot CD

3. share the two filesystems with your install server

   {x86}# share -o ro=<install server>,anon=0 /cdrom/sol_10_x86/s0
   {x86}# share -o ro=<install server>,anon=0 /cdrom/sol_10_x86/s2

4. mount these shares on the install server

   {sparc}# mkdir -p /a/s0
   {sparc}# mkdir -p /a/s2
   {sparc}# mount -o ro <x86 system>:/cdrom/sol_10_x86/s0 /a/s0
   {sparc}# mount -o ro <x86 system>:/cdrom/sol_10_x86/s2 /a/s2

5. setup JumpStart

   {sparc}# cd /a/s2/Solaris_10/Tools
   {sparc}# ./setup_install_server <path to jumpstart dir>

6. unmount share

   {sparc}# unmount /a/s0
   {sparc}# unmount /a/s2
   {sparc}# rm -rf /a

7. unshare the filesystems

   {x86}# unshare /cdrom/sol_10_x86/s0
   {x86}# unshare /cdrom/sol_10_x86/s2

8. eject CD

That's it.
