X2100M2 Embedded LIghts Out Manager best practice

Hi guys,
I'm in worry about the best practice of configuring network interface on a X2100M2 Solaris 5.10 for the Embedded LIghts Out Manager. Hope you can help. I haven't find any documents of it which explain the best practice.
Here is the situation :
I've have 4 network interfaces but I only need two of them. So I decide to use the bge0 and the bge1 interfaces.
bge0 is the server interface with an IP with .157
bge1 is the ELOM interface with an IP with .156
In the past, it was the reverse : bge0 was the ELOM with .156 and bge1 was the network server int. with .157
Could you please guys let me know what is the best practice? Does the int.0 must be the server one? Is it possible to have network problem with this kind of configuration?
Thanks
Cheers,

hi guys,
No one have a clue? I've got some dukeDolars to offer...
Tks

Xserve PowerPC G5: Configuring Lights-Out Management (LOM)

Can Lights-Out Management be configured using Server Monitor on an Xserve PowerPC G5? Thank you.
I was wondering because the "Configure Local Machine" feature is disabled.

Hi,
I'm afraid the G5 Xserve doesn't have Lights Out. It's a feature only found on the Intel Xserves.
All the best
Beatle

Lights-Out Management is not showing full status

Hi,
Since I upgraded my Intel XServe to Leopard, I don't get the full Lights-Out Management (LOM) status any more.
In Server Monitor it is only showing the status for:
- Power
- Temperature
- Blowers
- Security
Not the
- Info
- Memory
- Drives
- Network
Any idea what's wrong?
Thanks,
JO

How Do I Disable Lights Out Management (LOM)?

I was happily running 10.5 Server yesterday on my Intel XServe. The outside world was able to see my web server just fine.
I updated to 10.6 Server late last night and now my http service is not visible to the outside world (or local LAN for that matter).
Suspecting it has something to do with Lights Out Management (LOM).
How do I get LOM to turn loose of the local IP address of the ethernet interface?

What makes you think the LOM has anything to do with this?
There are about two million other things I'd check before I'd worry about the LOM. In fact I can't even think how the LOM could have have effect.
For a start have you verified the services are running? What do the logs say? Can you hit the web service from the machine itself? What about other services that should be running on the machine?
Have you checked the network configuration to make sure the server's IP address hasn't changed, that the default route is set correctly?
Then there are external factors to consider - maybe coincidences that occurred around the same time as your upgrade and may be masking the problem. Have you checked that your port forwarding is set correctly in your router? Are you sure your ISP hasn't started blocking port 80 traffic?

Asking for Lights out Management?

Running 10 iMacs & 10 Min Macs.
We can lock, restart, power off, control, all of that.
But as soon as we try to power on from shutdown, it comes up with ARD not active, and Lights out management not supported.
Obviously LOM has been discountinued with Xserve, but has it been integrated somewhere else?
I dont understand how it can be asking for LOM when it doesn't exist anymore.
Is there a solution to this? How can we power the mac's on using remote desktop?
And yes, before you ask, they are intel based.
Ross.

Hi
". . . but has it been integrated somewhere else?"
As of yet, no. It's not clear if Apple ever will? It has only ever been available on Intel XServes only.
"I dont understand how it can be asking for LOM when it doesn't exist anymore?"
It's not specifically asking for it as clearly LOM does exist but not on your hardware. ARD supports this feature if you're supporting hardware that does which can only be Intel XServe models.
"Is there a solution to this? How can we power the mac's on using remote desktop?"
Yes - you walk round to them and power them on. You can't use ARD to do this. You can however use ARD to send a terminal command that will set a power management schedule that goes some way in doing this for you. Mind you if you're having to go round to them all to switch them on you may as well apply the schedule settings locally. In an ideal world and assuming you have a mac server you can either define the settings you want in the build image you use to push out to rest or apply the settings using MCX.
Depending which method you use the Macs will have to be switched on at some point.
Questions specific to ARD are better asked in the dedicated ARD Forum here:

Lights Out Management...

Hi all,
I'm having troubles getting LOM to work on my new Intel XServe. During the Setup Assistant, without knowing anything about this feature, I happily skipped setting it up, thinking that it would be easy to enable it later (if deemed useful). The server is installed as a gateway (eth0 is WAN and eth1 is LAN), it is running local DNS, NAT, DHCP, Firewall and I can access the Server Admin and Workgroup Manager remotely using the domain name that points to the server.
Now when I go to the Server Monitor locally on the server and try to connect via. 127.0.0.1, it seems to connect briefly (i.e. the status lights at the bottom of the app change to green for a second), then the server listing itself disappears from the Server Monitor (i.e. the interface appears that I've never added a server). Now, if I try to add the server again (using the same local credentials), it says that that server has already been configured. The only way to remove this vanishing entry is to relaunch Server Monitor and delete the offending entry in the few seconds before it connects and vanishes again.
I've tried using the "Setup Local Server" menu option in the Server Monitor, but it's not clear to me what these values should be and everything that I've tried so far doesn't work. Should the port 1 have the same settings as my WAN port and port 2 the same as my LAN port?
Any help would be appreciated as guessing and testing isn't getting me too far and I'm concerned that by skipping the configuration of LOM in the Setup Assistant, I've made this impossible to turn on now.
Thanks for any suggestions,
Mike P

Thanks for this.
I've read that Apple doc already (to no avail), but thanks for the link anyways, others might find it useful.
Just so I understand your suggestion, when configuring Lights Out Management for LAN access, I should use Server Monitor -> Setup Local Server and change port 2 (I assume that port 2 would correspond to eth1 which is my LAN port distributing addresses in the 192.168.1.* range) by picking a valid IP within that range (e.g. 192.168.1.100), and filling in my subnet mask and router information (255.255.0.0 / 192.168.1.1 respectively)? This would then allow access to the server through Server Monitor while connected locally to the LAN via. 192.168.1.100?
Does this imply that for WAN access to Lights Out Management I would need my ISP to provide me with 2 static IP addresses (one for Lights Out and the other for web / internet services)?
Thanks again,
Mike P

Lights Out Management - Crashing / Resetting

It appears that Light-Out-Management is crashing, and I would like to know if there is a way to restart the LOM controller manually.
I have a Quad-Core Intel Xeon Xserve (XServe2,1).
- 2GB of memory (from factory)
- 80GB boot drive, 1TB drive modules in bays 2 and 3.
- 1 power supply
- no expansion cards
- connected to storage arrays via Firewire 800
- both ethernet ports are in use, 1 connected to the internal network via gigabit ethernet, the other to the fallback ISP
I have have configured Lights Out Management via Server Monitor. It typically works well, delivers information, sends notifications when needed. The lights-out management controller seems to crash or stop functioning regularly. I can only tell this has happened when I stop receiving notifications and the machine no longer appears in the Server Monitor list. The network connection to the machine is up and all other services seem to function normally. If I remote into the machine and do "Configure Local Machine" in Server Monitor, I get the marble of doom for about a minute, and when the Configure Local Machine interface does appear, all of the settings are zeroed out. (i.e. 0.0.0.0 for IP, subnet and router. username and password are blank.) Trying to re-enter the settings delivers an unhelpful error.
Restarting the machine does not help, when it reboots the LOM settings are still zeroed out. However if I shut down the machine and have the power disconnected for a short time (until the back panel lights go out) and then power up the machine, everything goes back to normal.
This is the only Intel Xserve in the rack, and the only one running 10.5. All the others are G5s running 10.4 or Ubuntu. Server Monitor runs well on the other OS X machines.

This problem has existed since the Intel Xserve was released. I haven't found a solution yet. The LOM usually comes back when I remove power from both power supplies for 15 seconds or so, but I'm not inclined to shut down my servers as frequently as the LOM quits.
It would be valuable for us if it worked, since its ipmi compliant.

Lights Out Management - not accessable outside subnet

Have a new out of the box XServe and have configured the Lights Out Management Card for one interface port. Works great locally and on the same subnet, however, outside the subnet can not connect to it. Server is in a layer 3 environment, does the Lights Out protocol use broadcast packets (as those could be what is being blocked).
Lights Out Port has IP, Subnet mask, and Gateway configured properly (double checked, and triple).
Thanks

i 'believe' LOM does not work outside the local subnet. annoyingly.
not even sure why.
[quote]Using Server Monitor
The Xserve comes with the Server Monitor application. You can find Server Monitor in
/Applications/Server/ and on the Admin Tools disc that comes with the Xserve. You can
use Server Monitor to:
Â Check the current status of the Xserve and its components, including
Â Drive module status
Â Power supply status and system internal voltages
Â Network interface status and activity level
Â Temperatures of critical internal components
Â Cooling fan status
Â Review basic Xserve information such as
Â Uptime
Â Mac OS X Server version running on the Xserve
Â Amount and type of memory installed in each slot
Â Model and capacity of each drive module
Â Shut down, start up, or restart the Xserve
Â Generate an Apple System Profiler report for the Xserve
Â Send email alerts in response to changes in the status of the Xserve
You can run Server Monitor on the Xserve or on any computer that can connect to the
same network. [/quote]
notice the last line....
if anyone figures anything out i'd be grateful. i thought i'd use the second enet int'fce and configure it for LOM, giving it a second WAN IP, but i abandoned that idea for some reason.. can't remember why that wasn't working....
also, this may help: http://www.afp548.com/article.php?story=20070211101829496

Lights-Out Management Settings - Confusion

Just installed my new Intel Xserve. There doesn't seem to be any documentation for Lights-Out Management settings. At first I decided to just copy the external and internal network settings for LOM. The assistant didn't accept that. Then I used another real IP numer for the external and different one out of my internal net for the second interface (server internal IP 192.168.2.1 LOM 192.168.2.2). To no avail. Whenever I try to connect to these addresses using server monitor I get no answer from the server.
Could someone please explain a typical setting for LOM?
Thank you very much in advance!

Tim,
I could not get your suggestion to work. So I called Apple. Together Apple and I could not get it working either.
So I am back to square one. The biggest problem here folks is the terminology. In the Server Assistant (that runs automatically after the server operating system has been installed) talks about "channels," not ports. I am making the assumption that they are talking about Primary Port and Secondary Port or Port 1 or Port 2. Geez, talk about inconsistency!
Tim: When you say your "secondary port," I am not sure whether you are referring to Port 2 on the physical server. I don't have an Ethernet cable running to, nor I do intend to, as this should work on Port 1, no?
I plugged an Ethernet cable into Port 2 of the server and still no dice. I can ping the IP address I put in Server Monitor for LOM on either primary port or "secondary" port from another computer. I just cannot use its IP address on a remote computer to get it working!
The Apple guy said on the phone that you need to use the LOM IP address, and alluded to the terminal to change it, but also inferred that this can also be done in Server Monitor as Tim spoke about earlier by adding the srever as local host (127.0.0.1).
Very frustrating... Other than this fault, I am sure that the server works fine, but I would like to have this ironed out before I proceed.
By the way, the settings for LOM are stored on the logic board and will be automatically filled in if you erase and install the Server Monitor hardware.
Some one please write if you get this more concretely nailed down, and of course, I will keep everyone apprised if I make any headway get this working.

Lights-Out Management Firmware Update

I tried to execute the Lights-Out Management Firmware Update, which Apple released, today.
But my Xserve always gives my an error, when I start the update application.
Lights-Out Management Firmware Update: Bad executable (or shared library)
Does anybody have the same problem?
Thanks and Regards,
JO

There's a new firmware update out, version 1.1. I tried simply using Software Update but no luck. It seemed to think it installed both 1.0 and 1.1, but all I saw was 1.0, which (still) did not work.
But I tried something else, and I think this works. I cannot test it until tomorrow when I can actually touch the server (to unplug it).
Open the Terminal application and do the following (omitting the "% " which I include to indicate the prompt).
% sudo rm /Applications/Server/Xserve\ Lights-Out\ Management\ Firmware\ Update.app
% sudo rm /Library/Receipts/LOMUpdate.pkg
% sudo softwareupdate -i LOMUpdate-1.1
The last step is important. It should only download the 1.1 updater. This seemed to work for me. that is, it downloaded the 1.1 updater, which I was able to run (from /Applications/Server/). However it tells me I need to shut down and unplug the the Xserve for one minute, then boot up, then install the update. I cannot do that until I'm back at work tomorrow. We'll see!

Lights-Out-Management - Same or different IP ?

Hello,
I manage 5 remote xservers (intel - recent model) which are located in a data center. ARD and remote desktop is fine, but lights-out-management is not working
reliably.
Which is the correct way to set it up?
I have tried two ways:
A) Configuring LOM to use the same IP as the server itself
B) Dedicating a different IP to the LOM interface.
It wasn't working well on (A), so we gave each server a second IP, just for the
LOM. However in ARD there is no way to add this second IP as part of the machine details in the Edit details window. Just the user/pass details for LOM. If I configure for (B), in Scanner I can see the servers listed by their LOM IP, but they are not responsive to PowerOn, Shutdown etc requests issued from ARD.
How do others have LOM configured?
and does it work well for you for remote management?
Thanks
Paul

The LOM needs to have it's own IP. It has to be unique, and ARD expects that it is. "B" is the correct configuration.
You should add the Server to ARD using the IP address assigned to the server, not the LOM. I believe ARD "asks" the Server what it's LOM IP address is once the LOM username and password is supplied.

Multiple room management -- best practice -- server side http api update?

Hi Folks,
Some of the forum postings on multiple room management are over year old now. I have student/tutor chat application which has been in the wild for 5 months now and appears to be working well. There is a single tutor per room, multiple chats and soon to be a whiteboard per student, which is shared with the tutor in a tabbed UI.
It is now time to fill out the multiple tutor functionality, which I considered and researched when building, but did not come to any conclusions. I'm leaning towards a server side implementation. Is there an impending update to the http api?
Here is what I understand to be the flow:
1) server side management of who is accessing the room
2) load balance and manage the room access 1 time user and owner session from the server side
3) for my implementation, a tutor will need to login to the room, in order for it to be available
4) Any reconnection would in turn need to be managed by the server side, and is really a special case of room load balancing.
My fear is that at some point I'm going to need access to the number of students in the room or similar and this is not available, so that I'll need client functionality, which will need update the server side manager.
As well, I'm concerned about delays on the server side access to which might create race conditions in a re-connect situation. User attempts to reconnect, but server side manager thinks that the user is already connected.
Surely this simple room management has been built, does anyone have any wisdom they can impart? Is there any best practice guidance or any samples?
Thanks,
Doug

Hi Raff, Thanks a ton for the response.
I wasn't clear on what I was calling load balancing. What I mean by this is room assignment for student clients. We have one tutor per room. There are multiple students per room, but each is in their own one-on-one chat with the tutor.
I'm very much struggling with where to do the room assignment / room managemnt, on the server side or on the client side (if that is even possible). In my testing it is taking upwards of 10 seconds minimum to get a list of rooms (4 virtually empty rooms) and to query the users in a single room (also a minimum of users/nodes in the queried room). If after this point, I 'redirect' the student to the least full room, then the student incurs the cost of creating a new session and logging into the room. As well I intend to do a bit of xml parsing, and other processing, so that 10 seconds is likely to grow.
Would I see better performance trying to do this in the client?
As far as the server side, at what point does a room go to 'not-active'?
When I'm querying the roomList, I am considered one of the 'OWNER' users in the UserLists. At what point can it be safe to assume that I have left the room?
Is there documentation on the meaning and lifecycle of the different status codes? not-active, not-running, and ok? Are there others?
How much staleness can I expect from the server-side queries?
As far as feature set, the only thing that comes to mind is xpath and or wild card support for getNode() but i think this was mentioned in other posts.
Regarding the reconnection issues, I am timing out the student after inactivity, and this is probably by and large the bulk of my reconnect use cases. This and any logout interaction from the student presents a use case where I may want reassign the student return to the same room as before. I can envision scenarios of a preferred tutor if available etc. In this case, I'll need to know list of rooms. In terms of reconnection failover, this is not not a LCCS / FMS issue.
Thanks again for responding.

Hotfix Management | Best Practices | WCS | J2EE environment

Hi All,
Trying to exploit some best practices around hotfix management in a J2EE environment. After some struggle, we managed to handle the tracking of individual hotfixes using one of our home-grown tools. However, the issue remains on how to manage the 'automated' build of these hotfixes, rather than doing the same manually, as we are currently doing.
Suppose we need to hotfix a particular jar file on a production environment, I would need to understand how to build 'just' that particular jar. I understand we can label the related code (which in this case could be just a few java files). Suppose this jar contains 10 files out of which 2 files need to be hotfixed. The challenge is to come up with a build script which builds -
- ONLY this jar
- the jar with 8 old files and 2 new files.
- the jar using whatever dependent jars are required.
- the hotfix build script needs to be generic enough to handle the hotfix build of any jar in the system.
Pointers, more in line with a WCS environment would be very much appreciated!
Regards,
Mrinal Mukherjee

Working with version management and promotion management best practices BO 4.1

Hi Experts
I wondered if anybody knows if there is a document or something about best practices to work with the version management and promotion management in BO 4.1?
Our Environment includes two servers. The first one is our development and test server. The second server is our prod system.
Now on the dev server we have basically two folders called dev and test. We control access to them with a right system based on the folder structure.
My question now is how you would work in this scenario (third server is not an option). Main target is to have as few reports as possible. Therefore we try to work with the version management system and only have one version of each report in the dev folder of the cms. But this is where problems start. Sometimes the newest version is not the version we want to publish to the test folder or even prod server.
How would you publish the report to the other folder? Make a copy of the concerned report (transport to the same system via promotion management is not possible). Also how would you use the version management in regards to the folder structure? Only use version management in dev folder and export reports to test folder (out of vms control) or also use vms in test folder and how would that work?
Further more I’d be interested in learning best practices with promotion management. I found out that the promotion of a report that doesn’t exist in prod doesn’t make any problems. But as soon as an older version already exists there is only partial success and the prod folder gets renamed to “test”.
Any suggestions on how to handle these problems?
Thank you and regards
Lars

Thank you for your answer.
So you are basically proposing to work with the vms in the dev folder and publish the desired version to the test folder. And the test folder is out of version control in this scenario if I understood you correctly (like simple data storage)?
And how would you suggest promoting reports to the prod system? Simply by promoting the
desired version from dev folder directly to prod? This would probably lead to inconsistence because we would need to promote from dev system to test and dev to prod instead of promoting a straight line from dev over test to prod. Furthermore it would not solve the problem of the promoting result itself (A new folder called dev will be generated in prod but the report gets promoted to the prod folder if there was no report before).
Thank you for the link. I came across this page just a few days ago and found also lots
of other tutorials and papers describing the basic promoting process. The promoting process in general is clear to me but I wondered if it is possible to change some parameters to prevent folder renaming for example.
Regards
Lars
