Re: Sun Fire v490 / Solaris 9 booting from CD, Network problems

Hi Folks,
Apologies in advance for the length of this post.
For the purposes of disaster recovery I have built a custom CD based on the Solaris 9 installation disk with our third party backup / restore software included on it.
After the rcS script has setup networking it runs a bash shell so that I can label / partition / format the hard disks as necessary then use the third party software to recover the system.
This works fine on almost all the machines we've tested (Ultra 10s, Ultra 30s, FS Prime Power 400)
On one Sun Fire v490 however I seem to have problems with networking...
Part of the customised rcS script makes the following call
ifconfig ce0 10.4.20.20 netmask 255.255.0.0 upto configure the NIC. However when the rcS script leaves me at the shell I'm unable to ping anything.
The output from ifconfig - a looks like...
lo0 flag=..
inet 127.0.0.1
ce0: flags=1000823<UP BROADCAST,NOTRAILER,MULTICAST,IPv4>
mtu 1500 index 2 inet 10.4.20.20 netmask ffff0000 broadcast 10.255.255.255 ether 0:14:4f:0:be:beThe only thing that looks odd to me is that there's no "RUNNING" entry for ce0 that I get if I boot from the same CD on my other machines (Ultra 30s & Ultra 10s)
The broadcast address looks wrong, but again it's the same when I boot from th CD on my other test machines and they all seem to work.
I'm pretty sure that ce0 is "plumbed", 'cos if I "unplumb" it from the shell prompt then it doesn't even appear in the output from ifconfig.
Someone has suggested that it's a connectivity issue, but if I boot normally rather than from my custom CD then the networking is fine.
As a test I tried removing the drivers for hme from the CD then booting one of my Ultra30s but in this case the entry for hme0 was completely absent from the output of ifconfig.
So I've concluded that the driver for ce0 is at least there on the v490.
So for the moment I'm confused as to why the ce0 appears on the output for ifconfig, but has no RUNNING 'flag'
Anyone got any ideas
Many thanks in advance
Regards
Kevin

hello
you have an error in your interface configuration
you should have
you are using a class A ip adress but with a class B netmask
ip 10.4.20.20
netmask 255.255.0.0
broadcast should be 10.4.255.255

On Sun fire v490 - Solaris 10 with Oracle 8.1.7.4 & Sybase 12.0

Hi,
We are going to upgrade our server with this configuration -
Sun Fire V490     2 x 1.05 GHz UltraSPARC IV CPU
8096MB RAM     2 x73GB local disk
2x FC 2GB Sun/QLogic HBAs
DAT72
On one machine we will have Sun Solaris v10 with
Oracle DB v8.1.7.4 & Second one will be Sun Solaris v10 with Sybase DB v12.0.0.6.
Now our question is - Sun fire have Hyper-thread CPUs �� will the O/S and databases (Oracle and Sybase) view the proposed system as a true 4 CPU platform? Will parameters used to tune the database such as Sybase max online engines still operate in the same manner as before?
Our old machine configuration was - Sun E450     4x400MHz CPU     1024MB RAM     2 x18; 8x36GB disks

Questions on Oracle and Sybase should be directed to a database forum, this forum is for Sun hardware support.
Here is a link to a DB forum I look at from time to time:
http://www.dbforums.com/index.php
The topic of tuning Oracle or Solaris is way beyond the scope of this forum, I have attempted to go into it before but didn't get any feedback and I would only like to spend lots of time on it if I was being paid!!! On the memory side, keep in mind that Oracle 9i 64-bit can address a maximum of 2 ^ 64 ( 16777216 TB ) memory, prior to that the DBA had to define memory parameters in init.ora. To be honest the last time I worked with a Oracle 8 database I shut a HP K class server down permanently that had been migrated to Oracle 9i on Solaris by an Oracle consultant and I can't remember all the tuning trick etc.

I don't think the test-scsi command is viable for that platform.
The FC disks are "viewed" by the system as external to the SCSI controller, almost as if they were in a multi-pack.
They are FC drives addressed by the chipset as SCSI disks.
Try:
<pre>probe-scsi-all</pre>
Edit:
Which release of Solaris 10 are you trying to install?
Older releases that might be fine for V480's won't work on V490's.

Now what is the other way to login into server console. I am entering in the console using normal mode, should I try to login in using diagnostic mode., or is there any other way to login into and modify the file.

Lack of running for an interface normally means network connectivity issue.
Check the network cable is plugged in securely.
Check for light on ethernet card and switch connectivity light.
Try a different switch port or switch and a different ethernet cable.

Sun Fire V490 x 2 servers with Oracle RAC facing Split brain problem

Hi all,
I have Sun Fire V490 x 2 servers with Oracle RAC and they faced a Split brain problem. One of the node's database instance has gone down, The DBA claims it is due to network problem, but as such the networks are OK. We use the on board CE1 interface for Cluster interconnect and CE0 as the public interface.
Did anybody face this kind of a problem? Could this be a hardware/OS patch problem?
I had kept a continuous ping for 24 hours after this happened last time and the output shows no packet loss
Many thanks in advance.

In order to diagnose this properly, you'll need to provide too much detail and far too many log files for a generic discussion forum to handle.
Use your service contract and open a support case.
Because a cluster environment is involved you'll likely end up talking to the cluster support staff.
They can analyze hardware and software errors as well as review whether you configured the systems in a supportable fashion.
Be prepared to make a direct connection to each system and gather data using such as by using the Explorer tool. The technical support staff will tell you what they will actually need.

How do I stop my ibook from trying to boot from the network

I have an older Ibook 4g and I have been trying to learn how to use it. Somehow I changed the boot from the hard drive to boot from the network. can someone help me? Also I would like to upgrade the os from osx 10.3 to a newer version.

Don't apologize for asking for help. That's why we're here.
Have you tried starting up in Safe Mode? If not, I suggest that you give it a try. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once started up in Safe Mode, go to System Preferences > Startup Disk and select the Mac OS X startup volume (Macintosh HD unless the name has been changed). Then try starting up normally. If you are now able to start up, go to Applications > Utilities > Disk Utility and repair permissions on the hard drive.
If you still can't start up into OS X, it may be an indication that the hard drive has problems. In that case, having the system discs is almost essential.

Booting from external HD problems?

Hi There,
My wife's iBook (OS 10.4, G3 800 which got a new mother board 6 months ago) died again last week. She was out of town so in desperation she got the HD removed by a technician and put it in a USB-2 external box so she can access her data from her colleague's G4 iBook, but she was unable to start up on it.
Since then I've tried booting from it on my 1.6 PowerBook (OS 10.4) and my old iMac (OS 10.3) and neither of them worked. The iMac will recognise the HD in System Preferences/Startup Disk but does nothing when "restart" is selected. The PowerBook mounts the HD on the desktop but won't see it in Preferences. I tried to verify/repair the disk with Disk Utility while it was on the PowerBook but it said nothing was wrong (Verify/Repair Disk Permissions were not available).
Eventually I connected the HD through a bus powered Firewire device and it boots ok on the iMac but when plugged into the PowerBook I get a message saying the disk is unreadable and prompts me to reformat it.
Does anyone have any idea what's going on?? Please explain.
Thanks, P.

The Powerbook should not have a problem
powering the drive, but we need details.
Details do matter. The FW ports can supply no more than 7 watts of power, which may or may not be enough to run the drive, depending on the characteristics of the drive, the enclosure's power converter & circuitry, & the power source for the Powerbook. It is possible that the PowerBook cannot supply enough juice to spin up the drive quickly at startup time, making it difficult to boot from.
The reasons for this are technical, having mostly to do with the unregulated voltage FW ports supply & the power surge drives generate during spin up.
At the least, the O.P. should try disconnecting anything else from the FW ports & using the PB's AC adaptor while trying to boot from the FW drive.

P965 Neo: Boot from USB-Stick problem

Hi!
I have a problem with booting from a USB-Stick (FAT) with the P965 Neo board, Bios Version 1.5.
The USB-Stick will not be detected properly as a boot device (HDD) in the bios setup. It appeared only
once at the 'Hard Disk Boot Priority' list and sporadically at the 'CD-ROM Boot Priority' list (which is not always there).
Can anyone please point me to the correct bios setting to boot properly from the USB Stick?
(Booting from the USB Stick works fine on a ASUS board, so the USB Stick itself is bootable).
Here is my attached hardware:
SATA Harddrive
IDE DVD Burner
(both connected to the JMicron SATA/IDE controller)
thanks,
-phazer-

I use software called "Flashboot" to format my USB Stick, this software has options to format USB stick as USB-FDD, USB-ZIP or USB-HDD. You can use built in Free-DOS as your USB Stick OS. I have formated it as USB-ZIP and set my BIOS to boot with USB-ZIP and i didn't have any problems. Try this software it's very simple to use and user friendly. Only problem is that is not freeware so if you use trial version you can boot only once and after that you must format it again.

Booting from external dsrive problems

I have tried several methods for booting and not one has worked,, First i zero out my drive thenn put it in an enclousre and booted form the Mac Osx DVD and installed everything, (a normall installation) I try to boot, nothinh just a gray screen for 10-15 minsa then it boots form internal drive. I buy a new case, same problem, i also try another drive same trouble. I have even made an edrive with techtool, and still, it wont boot. any help woulod be nice.

Is the drive you are booting from Firewire? PowerPC Macs can only boot Mac OS X off Firewire, and not USB. Also did you make sure the enclosure has the latest firmware and is known to be Mac OS X bootable?

Problem with RSC card on sun fire v490

Hi all,
I have a little problem.
I got few v490 that were already used.
When I connect to the management port of the RSC card I get the prompt of the RSC password, somthing i don't have.
The OS doesn't get loaded and I can't do anything. ( if I had access to the OS I would have reseted the password)
So now, I got left with the only option i thought of.
1. Disconnect the RSC card,
2. This will force the output of the consol to go to the serial port(tty).
3. Jumpstart the machine (beacuse I don't even have the password for the machine)
4. connect the RSC card, and reset the password.
There is someone here that encountered this problem??
Maybe there is a jumper that can reset the RSC password. i don't know... every response will be great!
Thanks!!!
