solaris >> diskless Solaris 10 setup?

by Dave Littell » Thu, 10 Aug 2006 09:47:15 GMT

Hi all,

I have a set of x86-based systems that I'd like to configure
diskless and then serve their filesystems from a single RAID server.
One catch is that each system has different hardware and will
require different drivers. I'm guessing that I can put the superset
of drivers in a (common) root filesystem that's mounted via NFS, but
I really don't know where to start setting this up from either the
server or client side. Can someone provide any insight?


Thanks very much,
Dave

1. Diskless station with Solaris 10 (sparc64)

	Hello,

	One of my servers (192.168.1.71) must boot by network from a Linux
	server (192.168.1.254) and I have some troubles with network boot.

	I have created a tftpboot image with add_install_client. Thus, in
	/boot/tftpboot on linux server, I have :

Root gershwin:[/boot/tftpboot] > ls -l
total 4863
lrwxrwxrwx 1 root root      14 Oct 19 15:51 C0A80001 -> vmlinux-2.6.23
lrwxrwxrwx 1 root root      14 Oct 19 15:51 C0A80002 -> vmlinux-2.6.23
lrwxrwxrwx 1 root root      27 Oct 19 16:52 C0A80147 ->
inetboot.SUN4V.Solaris_10-1
lrwxrwxrwx 1 root root      27 Oct 19 16:52 C0A80147.SUN4V ->

-rwxr-xr-x 1 root root 4949443 Oct 19 15:51 vmlinux-2.6.23
Root gershwin:[/boot/tftpboot] > 

	I have written a /etc/bootparams file :

Root gershwin:[/boot/tftpboot] > cat /etc/bootparams 
dvorak  root=192.168.1.254:/export/home/srv/solaris10-dvorak \
        boottype=192.168.1.254:in \
		rootopts=192.168.1.254:rsize=8192

	dvorak is the name of diskless server. When dvorak tries to boot, it
	downloads tftpboot image and uses rpc.bootparamd :

Root gershwin:[/etc/init.d] > rpc.bootparamd -s -r 192.168.1.254 -d
bootparamd: whoami got question for 192.168.1.71
This is host dvorak.systella.net
Returning dvorak   (none)    192.168.1.254
getfile got question for "dvorak" and file "root"
returning server:192.168.1.254 path:/export/home/srv/solaris10-dvorak

getfile got question for "dvorak" and file "rootopts"
returning server:192.168.1.254 path:rsize=8192 address: 192.168.1.254

	and :

	But on diskless side, I only obtain :

OpenBoot 4.25.3, 8184 MB memory available, Serial #78099454.

Rebooting with command: boot net
Boot device: /pci@7c0/pci@0/network@4  File and args:

boot: cannot open kernel/sparcv9/unix
Enter filename [kernel/sparcv9/unix]: 

	I think that diskless station doesn't mount its nfsroot, but I don't
	know how fix this... Any idea ?

	For information, nfs server exports /export/home/srv/solaris10-dvorak
	than contains a solaris10 root filesystem.

	Regards,

	JKB
