Troubleshooting a Netra X1



  • 1. Automating an install
    I need to install SSH on about 40 solaris boxes, however installing 5 packages and seting it up to run on all the boxes is a lot of work. Is there a tool I could use to automate this install procedure. I mean, I thought of writing a script but do not know where to begin.
  • 2. ftpd logging
    I am currently logging all ftp sessions to a log file and would like to either eliminate password entries or have them written to the log file in an encrypted form. Is there a way to do this? Thanks, Tony
  • 3. Solaris ACL support for find?
    Well, hmmm. A possible hacky starting point is: find somedir -ls | nawk '{if(length($3) == 11) print $11}' Note that find . -ls prints a trailing + on the file permissions (ala /bin/ls) when the file in question has an acl. The question is what you're trying to check... the combinatorial effects of permissions, acls and default acls can be confusing. - Bart Jeff Wieland < XXXX@XXXXX.COM > wrote in message news:<c9nubv$d4n$ XXXX@XXXXX.COM >... > I'm looking for a find-like tool that can check if a file has a certain > ACL set.

  • 4. strange "uname -v" output on Sun Fire V210
    OS: Solaris 8 with latest recommented patch cluster Platform: SunFire V210 We just bought a Sun Fire V210. before I did jumpstart on it, the "uname -v" output is: Generic_108528-18 But after I jumpstarted it, the output of "uname -v" is: Generic_117350-02 I used the same jumpstart server to jumpstart a Sun SParc 5 and Sun Fire V120, both output of "uname -v" are: Generic_108528-29 Any idea why "uname -v" is differnet for Sun Fire V210? Thanks.
  • 5. T3 cache
    Hello all, I just replaced batteries in a couple of T3s and now that they are charged it seems that the cache is not enabled. If there something special that must be done to bring the cache back online? We're taking a terrible performance hit cause of this. Thanks, Mark

Based on this output, is there something wrong with this Netra X1 or am 
I doing something wrong?  How do you boot from a CDROM drive? or a Netboot?

Maybe you should type

I have tried that command.  I get "system is in standby mode"

If I type 'poweron' I can hear the powersupply fan and that's it.


Re: Troubleshooting a Netra X1

At the lom prompt, do this instead:

lom> poweroff

Wait 5-10 seconds.

lom> poweron

And let it sit for a few minutes. No need to physically push the power
button as you can remotely manage the system via LOM.

Do you see anything like this, anywhere?

LOM event: +0h3m52s overheat sensor 1 FATAL FAULT: overheat - shutdown req'd
LOM event: +0h3m52s host power on
LOM event: +0h3m52s Fault LED 3Hz
LOM event: +0h3m53s overheat sensor 1 no overheat

LOM event: +0h3m58s host power off

The reason why I ask is because the X1 is infamous for having a failed
temperature overheat sensor which is enclosed in the PSU. If you have a
failed temp overheat sensor, you're going to have to somehow find a new
Netra X1 PSU -- loads of fun there.

If you don't see these exact messages, then it's probably not the
infamous temp sensor overheat problem.

If you still aren't getting anywhere... then try:

<press enter key once>
<press #. keys>
lom> bootmode forth
lom> reset

...and see if you eventually get dropped into the OpenBoot PROM (OBP)'s
ok prompt.

If you get that far, you can boot off a CDROM by doing 'boot cdrom', or
off the network by doing 'boot net'.

Thank you for your response.  I don't believe I've seen the error 
messages about the PSU.  I also tried the other set of instructions and 
I still have got the OBP prompt.  I can type the 'bootmode forth'
command but when I type 'reset' I get 'system in standby mode'

There is a SCC card inserted.  When I remove it then I get the error 
message that the card has been removed.  Other than that, there is not 
much I can do outside of the LOM.  I hope this helps.  Thanks for your 
help.  This is first Sun hardware I have ever own.  Just wanted to see 
how it works.

A good first step would be to go to and RTFM, particularly
the introductory stuff about LOM.  If you truly have the OBP prompt (not
to be confused with the LOM prompt), then you should be able to boot up
(unless the disk has been wiped, in which case you should still be able
to boot net after first setting up a boot server).

Nothing you've said gives me any reason to believe the hardware is
faulty, but I suspect you don't have an OS on the disk.

An X1 would not be my first choice of system to cut my teeth on, because
of its lack of a normal framebuffer/keyboard console.  You might do
better to sell it (to me, e.g.  :-)  ) and get a more regular desktop
type Sun like an Ultra 10, which might be similarly priced.

Mr. CTJ,

RTFM huh? I RTFM BEFORE I got the server. I've used Goggle.  I took 
notes and tried the commands, it hasn't worked.  I know what the LOM 
prompt and the OBP prompt look like.  Which is why I'm wondering if this 
Netra is bad. I didn't pay for it, I got it because someone I knew 
didn't know how to test it.  Seeing as how I never paid for this server 
it's not a total lost to me if it doesn't work I have another Sun server 
to work on.

I'm only trying to install a OS on it that's why I am hoping to boot to 
a CDROM.  Or at least to troubleshoot the server and learn about Sun 

I thought I could come to this newsgroup and ask for help.  It's people 
like you and you {*filter*} comments that making this fustrating.  Others 
have offered advice and have emailed me directly and I thank them. You 
don't even know me and you are posting smart-ass comments towards me. 
All I am asking for is a little help.  If it was the other way around I 
wouldn't be a smart ass like you.

I don't want to start a flame war, I just want to learn about Sun 
hardware. If you are want to help then I would apperciate it. If you 
want to be a smartass then keep you comments to yourself.  I know these 
newsgroups gets flooded with newbie questions.  I posted my stuff 
because I want help on what to do when it doesn't work like the manual

I think you need to grow more skin. You'd never survive posting

Your reaction to the recommendations and frustration with this seem to
limit our (and your options). I've seen plenty of

"Try this"
"That doesn't work"
"OK, try this"
"That doesn't work either"

in this thread.

Either your system is really busted quite badly and you need to replace
it's innards or this is a "I need a 710 under my hood. It fell off and
needs to be replaced." problem:

It's your call if you want to pursue help via this newsgroup which only
seems to be pissing you (and us) off or hire someone or take it to a SUN
reseller to find out if it's really working or just a bunch of parts now.

Obviously not, and google isn't the right place to look.
Why not use Please read this:


Especially chapter 6 and/or page 29. Page 52 may also be
interesting, if the previous owner seperated the console
from the lom.

2.Netra X1, Corrupt text received via serial connection


I have just got hold of a Sun Netra X1 and would like to install
Solaris 9 (or 10) onto it.

The problem I have is that when I connect to the serial console I get
the LOM prompt alright, but after typing some commands like "help" I
get back scrambled text with some parts recognizable. I am using a
Cisco serial cable which has the same pinout as the sun original cable
(I have also made up a cable as per the Sun spec in the netra manual).

I have also tried connecting to the server via a Linux server, a Sun
Sparstation 5 and a windows laptop (using a variety of software
hyperterm, kermit, etc). All have the same issue.

I'd be very grateful for any opinions, ideas, etc.

3.Netra X1 - Can't open boot device


I'm rebuilding a Netra X1 with Solaris 8 2/02.....

I can build it off the network, and the build goes successfully.
However, when I reboot, and the box tries to boot from disk, it gives
me the following:

Boot device: /pci@1f,0/ide@d/disk@0,0   FIle and args:
Evaluating: boot disk

Can't open boot device


and then it tries to boot from the network again. Any thoughts? The
hardware is good, I just can't seem to point it to a good boot device.
Please help.

Hi everybody,

I've got virtually no experince with Sun hardware, I've done some
