  • 3. LPFC instance number renamed during boot, Solaris 8
    Hello! We have seen on several occasions that the lpfc instance number gets renamed during boot. This of course leads to the renaming of the controller number for the disks, so that cxt0d0 is changed to cyt0d0. We have seen this on several servers, all running Solaris 8, but with different patch levels. They all use the Emulex driver (we use Emulex HBAs) and the storage itself is EMC Symmetrix. Also, the problem is not reproducible all the time. It can happen to a server once in a while, and then "never" again, or it can happen again after several normal reboots. The guys here are not sure if it has only happended during a "boot -r" or if it has happened even during a normal boot. Nevertheless this shouldn't be possible. Has anyone seen this behaviour? Does anyone have the solution to this? Many thanks in advance! -- ---J.T.U.

Your choice.  I like to install everything before the reboot
(possible with a network install, since the install image is not
limited to a single CD capacity).

Then I like to disable unneeded services before the reboot, so as to
reduce the initial exposure to attacks from the net.

Method 3 generates a start script (the here document between EOT) that
executes when the machine comes up and at the end deletes itself.

I release my modular jumpstart scripts because not everyone has the
time and energy to deal with such things as this. They automate
installing many things post-reboot for you with no intervention and
make it a lot easier to maitain lots of profiles that have much or

Most can be made to work. Either by passing the correct option(s), or at
worst using chroot.  If you happen to find any Sun packages which dont
work correctly with pkgadd -R then feel free to get a bug raise and they
should be fixed.

There's some details on the chroot method at
 http://www.**--****.com/ 's a little outdated - I
really should update it one day...

Alternatively, have a look at JET, the JumpStart Enterprise Toolkit. It's
available from  http://www.**--****.com/ 
It includes a framework which makes configuring packages fairly easy, with
the ability to do it either before the first reboot, or even automatically
on any subsequent reboots.

In article <1075198086.189564@docbert>,

i install only the OS during jumpstart proper.
i leave about 5 scripts in /etc/rc2.d to to the rest.

once the finish script pulls over the custom.tar, kitup.tar,
the machine doesn't do any appreciable network activity.
so if you've a bunch of machines to do on one subnet,
you know you can kick off machine # 2 when machine #1
reboots the first time.  ie, if you want to guarantee
you won't have two machines fighting for the network.

yep, you're working with /, not /a.  one less thing
to deal with.

i have many of my customizations in packages.  i've never
tried them against /a, maybe they will, maybe they won't.
but i don't care, of course.  so i saved myself some
testing by going against / instead of /a.

doubtless there's a down side--it certainly isn't as elegant
as "doing it right", but it works.

Here's one more opinion.  I generally don't have a problem with setting
things up in a finish script, but that doesn't make it easy to make
changes in your existing machines.

I'd prefer to spend my time setting up jumpstart to get the machine
built and "in the environment" (might be limited to SSH or NIS
membership), plus activation of some sort of maintenance software.

The maintenance software is on all the machines for
installing/configuring them.  That way installation of stuff after a
jumpstart is just a special case of making sure the correct stuff is on
all the machines.

That might be a real simple rsync (possibly combined with some startup
scripts that run extra commands) to a very involved cfengine setup.

1.jumpstart: Custom jumpstart profile isn't used

Hello again.

After getting the system to actually boot (thanks Wolfgang!) and to
display nicely (thank Mr. Chow Wing Siu!), I'm now trying to setup
a custom profile, so that the installation works without manual 

To do so, I first copied the S10U5 Sparc DVD to the install server
with setup_install_server. I then added the install client to the
system by running:

./add_install_client \
 -p sys01.unx:/data/software/solaris/Solaris10/U5/jumpstart/sysidcfg/sys02 \
 -i -e 00:03:ba:12:d3:04 -n 'none(' \
 -c sys01.unx:/data/software/solaris/Solaris10/U5/jumpstart/jumpstart \
 sys02 sun4u

In /data/software/solaris/Solaris10/U5/jumpstart/jumpstart, there's, 
among other things:

$ ls -al /data/software/solaris/Solaris10/U5/jumpstart/jumpstart
total 104
drwxrwxr-x    3 root     adm            22 May 14 17:11 .
-rwxr-xr-x    1 root     bin         59946 Oct 17  2007 check
-rw-r--r--    1 mike     staff         320 May 14 17:11 prog_profile

-rw-r--r--    1 root     root           55 May 14 17:11 rules.ok

rules.ok was created by running the check script. Contents:

$ cat rules.ok
any -                                   -                       prog_profile    -
# version=2 checksum=1874

$ cat prog_profile
# profile keywords  profile values
# ----------------- -----------------
  install_type      initial_install
  system_type       standalone
  partitioning      default
  filesys           any 512 swap # specify size of /swap
  cluster           SUNWCprog
  package           SUNWman delete
  cluster           SUNWCacc

(I also tried using a simple profile, where the keywords are on the
1st column. Doesn't make a difference.)

$ cat ../sysidcfg/sys02/sysidcfg
name_service=DNS {domain_name=unx
network_interface=PRIMARY {hostname=sys02

Pretty darn basic, isn't it? :)

Now I'm running "boot net - install" from the sys02 machine. It gets
the sysidcfg file (I see this, because snoop says so and because the
installation is colorful and thus must be using dtterm as terminal
and it's in german, thanks to my sysidcfg file).

But it's just not working - ie. when I run "boot net - install", I'm
presented the normal Solaris-Installationsprogramm and I've got to
select what cluster to install, how to slice the disks etc. pp.. Not
what I expected.

What am I doing wrong this time?

This time, all the paths *ARE* reachable; for sure :)

On a remote system, I did:

$ ls -la /net/sys01/data/software/solaris/Solaris10/U5/jumpstart/{jumpstart/rules,sysidcfg/winds02/sysidcfg,software/Copyright}
-rw-r--r-- 1 mike   wheel  170 14. May 17:11 /net/sys01/data/software/solaris/Solaris10/U5/jumpstart/jumpstart/rules

On /net, there's an automounter running.

2.grub jumpstart "file://jumpstart/config.tar" problem

I am trying to upgrade a server by booting from a DVD and specifying 
where to find its config info for a pretty much hands off upgrade.

The server to upgrade is a working and bootable Solaris 10 11/06 x86.
I want to upgrade it to Solaris 10 8/07 via its local DVD drive.

I insert the Solaris 10 8/07 DVD and boot from the DVD.
At the grub boot menu, I select "Solaris 10 via console ttya" (console 
is redirected on this server).
I change grub kernel line from:
   kernel /boot/multiboot kernel/unix -B install_media=cdrom,console=ttya
   kernel /boot/multiboot kernel/unix - install 
file://jumpstart/config.tar -B install_media=cdrom,console=ttya

On the hard drive of that server, there is a tarball file 
/jumpstart/config.tar containing the configuration files
  to use for upgrade:
# tar tvf /jumpstart/config.tar
drwxr-xr-x   0/0        0 Nov 28 10:24 2007 ./
-rw-r--r--   0/0      166 Nov 28 10:23 2007 ./rules
-rw-r--r--   0/0      748 Nov 28 10:20 2007 ./sysidcfg
-rw-r--r--   0/0       69 Nov 28 10:22 2007 ./profile
-r-xr-xr-x   0/0    59701 Nov 28 10:22 2007 ./check.s10u3-x86
-rw-r--r--   0/0       56 Nov 28 10:24 2007 ./rules.ok

Now when I boot from the modified grub menu, here is the output saying 
the compressed config file cannot be found:
Custom JumpStart
Using install cd in /dev/dsk/c1t0d0p0
Using RPC Bootparams for network configuration information.
Attempting to configure interface e1000g0...

This seemed so simple to me, what am I missing ? Anyone else doing/done 
this ?

4.UNIX in Vista (qualified opinions please)

Hello knowledgebase:

I  recently had an exchange with a coworker who told me that his friends @
MS told him that Vista's OS (or more specifically, its core kernel) shares
some commonalities with UNIX (or more specifically, its microkernel)... See
below for his claim:

"Interestingly enough the architect of NT based the OS Mechanics off of
4.3.0000 BSD UNIX and in turn the Vista core kernel incorporates more of the
UNIX micro-kernel system. I got that information from some friends at

If you have accurate/better info on the subject let me know.

It also
shows up with programming constructs that are more Unix like and the number
of easier ports like, PERL and scripting."

I am seeking qualified opinions on the accuracy of the above. Not being an
architect of NT -- I don't feel qualified to respond. Thanks in advance!

5.Any opinions from Linux users?

Just curious what y'all think of Vista, compared to other versions of Windows.
