Intel Xserve power problems

As of recently, I just started noticing a issue with powering on a new intel xserve. If the machine is running, using LOM and shut down works beautifully. After I shut it down, using LOM and the button works beautifully. If i attempt to turn it back on a few min later, it works fine.
If I leave it off for a day or so, even though the lights are on on the front of hte machine, LOM can see the server, but "power on" doesnt do anything, and hitting the front power button doesn't do anything. I have to unplug it from the UPS and replug it in for it to turn on.

Hi Forum folks.
I've had a 6-month (ish) Xserve doing the same thing. Every day, at least once a day, I'd get an email / SMS, saying the power supply or blower was having a momentary problem.
After shutting down the server, I pulled out the Power Supply Units, and checked them out.
Turns out, one of them had a slightly damaged heat sink (damage visible without opening the PSU). So, I swapped it for a spare I'd purchased. And then got the damaged unit (damaged internally at factory by the look of it) replaced by my Apple Reseller.
Note: the newer Intel XServes (early 2008) have a 750w PSU, compared to a 650w PSU, in the 2006 Intel XServes. The older PSUs fit in the newer Xserves, but they DO NOT function. (You'll get an error in Server monitor).
Hope that helps,
Cheers,
Derek

Xserve Power Problem

i have an xserve g5 single 2.0ghz. it is having a new weird power problem where it restarts after about 2 hours. i am almost positive that it isnt the power source (the wall) because i have tried different plugs and still the same problem. although it could be because it has never done this a couple of months ago when it was in a different part of the room. i do not leave it on 24/7, it is only on for max 3 hours a day. it also really only restarts when i do video editing and use it as a scratch disk. i need to know if its the power supply or my wall plugs or the power cord
thanks

Your two best tools here are monitoring and logging.
Server Monitor will report way more than you want to know about the internal hardware of your Xserve. Run it on another machine (so you can read the log after the Xserve shuts down) and it will monitor temperature, memory, voltage etc and any hardware anomalies should register here first.
Open Console and check out the log right before the shutdown for any messages - short of yanking the cord out of the wall just about any strangeness should be registered in log messages from one source or another. If you computer is deciding to shutdown because of anything it detects it will definitely be in there.
If you can find no apparent cause the only way to rule out the electricity is to put a UPS between the computer and wall and see if the behavior changes.
Good luck,

Intel Xserve Blower for Power Supply 1 Out drops to 0 RPM momentarily

10.5.6 Server. Machine is less than a year old. Yesterday I configured Server Monitor for the first time and have received two notifications of the blower for the Power Supply Out changing to zero RPM. It is momentary and goes back to normal.
Everything else is in the normal range -- temp, voltage.
Is this normal or indication of future failure?

Can't Power on Intel XServe

I'm unable to sucsesfully power up an intel XServe. After I plug back in the power it boots up, at least by looking at the front panel lights. The fan kicks into high, the power light comes on, the first set of activity lights come on and the system id light comes on. However, I don't get anything on the monitor. I have removed all the RAM thinking it was a memory issue but that had no effect. I took out the PRAM battery, removed all the drives. Still nothing. If I push the power/standby it seems to go into standby. If I then power it down and restart via the front pwr button it seems to cycle on and off or perhaps sleep. The pwr light comes on for 5 seconds, the system id light flashess 3 times then stedy, and the RAM lights come when the pwr light is on. The machine did come on last week but seems to have died sometime after last friday. Any suggestions would be great.
Brad

Brad, did you happen to have server monitor set up on this box? It would have been nice because you would be able to see the status on a remote machine.
Are you sure it is not actually booting properly but with no video? Can you ping it from another machine?
If you turn it on you say the sytem id light is flashing?

Server Monitor on Intel XServe Problem

2 weeks ago - our new XServe Intel arrived. It is our 3rd, one G4 XServe running 10.3.1 sind 2003, one DualG5 XServe running 10.4.8 since 2005 - nonstop uptime.
So both machines run well.
With the Intel XServe I installed the new AdminTools like ServerMonitor on a Powerbook G4 and a old G4-466 - both running 10.4.8
But now I have 2 Problems:
First: With Intel XServes Server Monitor I can access the 10.3 Server, but I cant see the little icons and check things like van rpm or CPU temperature - it just shows nothing. Using the G5s 10.4 ServerMonitorversion it works.
Second: I am unable to connect to the Intel XServe via Server Monitor - it always tells me "Auf Antwort warten" in English like "Waiting for response", not even with the G5 Softwareversion.
I already checked the com.apple.hwmond.plist file and startet the hwmondSetup in the Terminal - nothing works.
Even not, when I start the application on the XServe itself.
ServerAdmin and the rest of bundled software is running well.
Anybody knows?

Intel Xserve won't boot from 3rd party drive in ADM

Right, I've got a Late 2006 Xserve Dual 2.66 with the normal non-RAID SAS/SATA board, which has been running fine for 2 years with a pair of non-Apple Seagate Barracuda ES 250GB drives (Bay 1 & 2), and an original 80GB ADM in Bay 3 as a spare boot disk.
Bay 1 & 2 are set up using SoftRAID and are partitioned into a boot volume (30GB) and a data volume (200GB), both RAID 1 mirrors. The boot volume is cloned nightly to Bay 3 (single volume, set up using Disk Utility). Data is backed up to a utility machine, so this is arrangement lets me handle any single drive failing.
This arrangement has worked fine for 2 years, and allows me to remotely boot off Bay 3 and run DiskWarrior or other disk maintenance software on the normal boot drive without having to drive across town with a firewire drive. I originally started with Mac OS X Server 10.4, but I'm now on Mac OS X Server 10.6.4.
Where things have come unravelled is, I need to upgrade the two 250GBs to something larger. I didn't realise that the Intel Xserve is pretty fussy with ADM sleds and the model of SATA drive they will work with. I didn't have any issues when I set up the Barracuda ES 250GB so wasn't expecting any problems this time.
I bought a pair of Seagate Constellation ES 500GB drives (well 3 actually, one to keep on the shelf as a spare).
I installed them in the sleds and inserted them in the Xserve. The green power LEDs came on but the drives weren't recognised in Disk Utility or System Profiler. I then added the jumper to set them to 1.5Gb/s and then they mounted. I went through my normal process of cloning the OS to them from a standard disk image I have of a known working OS install, ran Disk Utility to repair disk & repair permissions, Disk Warrior to check everything else (my standard paranoid procedures). Set the startup disk to the new install and rebooted. No joy, just the flashing question mark folder. Reboot with the option key, and the new volume doesn't appear in the list of available boot options.
I installed the drives in a firewire enclosure, and it booted without any problems, so it's not a corrupt install, it's something to do with the ADM sleds.
So to go back to basics, I tried initialising a single drive as a single volume and installed 10.6.4 server fresh from the DVD. Same result, no boot when in installed in ADM sled, boots fine in firewire case.
Erased drive, changed formatting to APM (rather then GPT), cloned OS, etc. Won't boot when in ADM sled, boots fine from firewire case. So that screws the theory that drives have to be GPT to boot on Intel hardware.
So I ordered a set of WD RE3 500GB drives (x 3) and repeated this whole process. Same deal, boots fine in firewire, won't boot when installed in ADM. GPT vs APM doesn't make any difference.
Try #3. Ordered desktop variants rather than server class drives. So armed with a pair of WD Caviar Black 500GB. Same deal, boot fine from firewire, will not boot when installed in ADM. Also required jumpers for 1.5GB/s and also the undocumented pins 7&8 (apparently this might be related to the new Advanced Format they are using)
Try #4
A pair of Seagate Barracuda 7200.12 500GB. This is where it gets tricky. One of the Barracuda will boot the Xserve when installed in an ADM, and one will not. So 2 Barracuda 7200.12, both same model number (ST3500418AS), both same firmware (CC38), yet they behave differently.
Try #5
Barracuda ES.2 250GB (x 3). Won't boot in ADM, will boot firewire.
Try #6
WD Caviar SE16 250GB (WD2500KS)
Boots in ADM (Yay!!) and firewire
Try #7
WD Caviar SE16 500GB x 2 (WD5000AAKS)
Boots in ADM and firewire
I've managed to get access to G5 Xserve (2.3DP) so I've repeated all this testing on it as well. The G5 doesn't care about the model of drive and boots from any of them using a 10.5.6 install with APM formatted drives.
I've tried all these drives in 4 different models of ADM sled. One thing I have determined is that the model of sled determines if you need to use the 1.5GB/s jumper. I have 2 sleds from G5's, they require the jumper, a 80GB Intel ADM sled with separate data and power plugs requires the jumper, and an Intel 160GB ADM sled with the ribbon cable and combined data/power plug doesn't require the 1.5GB/s jumper. APM vs GPT formatting again makes no difference.
So on the Intel machine, the drives work in the sleds, appear as normal drives on desktop or in Disk Utility when logged in, and also appear as normal drives when connected via SSH if Auto Login is disabled. So to me they appear to be working drives.
It appears to me that something changed at a low level between the Barracuda ES and ES.2 generations of drives (for WD drives as well since the Caviar SE16 that boots is a similar age to the Barracuda ES)
So then why won't it boot from them? Is there some magic dance I've missed?
And how come one of the 7200.12 will boot, while another identical model won't?
Any tips or suggestions greatly appreciated.

I don't have an answer for you, but you deserve thanks for all the useful hardware information you posted from your trial-and-error testing.
My impression has that the XServes need specific kinds of firmware and hardware monitors on their drives in order for everything to function smoothly. My own efforts swapping drives in ADMs has produced "mixed results" to put it mildly. It would be so much easier if we knew what kinds of drives worked properly in what kinds of ADMs and on which Macs/XServes.

Bootcamp on new Intel XServe

Does anyone know if it's possible to run bootcamp on the new Intel XServe machines?
Boot Camp Assistant tells me I need to upgrade the firmware on the XServe before proceeding, but I cannot find this for the new XServes.
Does anyone know if this is possible?
I am trying to install Fedora Core 6 using bootcamp.
Regards,
Trevor.

>Well, hwmond won't be running, so the fans won't be controlled
Are you sure about that? hwmond simply logs the hardware status and sends emails if there's a problem. There's nothing in the man page that hints that hwmond is responsible for adjusting the fan speeds. Althouth I don't know for sure, I'd expect that there's firmware-level control of fan speeds based on temperature sensor inputs, not OS-level control.
> it's unclear whether all the ECC handling will be done
ECC would be handled by the (hardware) memory controller, not by the OS.
There might be no mechanism to check the state of the ECC (e.g. count errors), but I'd still expect to get the benefits.
> and power supply failover (if you've got the dual supplies) won't work
Again, I'd expect this to be handled by the firmware, not by the OS. hwmond is probably responsible for detecting the failure and reporting it (e.g. via Server Monitor and/or email), but I would still expect the basic power load balancing and redundancy to work - you'd may just need to periodically check the LEDs on the back to check PSU state.
Note, I'm not saying Boot Camp will work, or that it won't work, just that I don't expect these hardware-level features to be affected.

Intel xserve + OS10.5

I'm about to set up a small office network based around an xserve but with the advent of Intelised Mac and the prospect of OS 10.5, I'm now in a quandary as to whether to wait. We will soon start replacing the older office iMacs with new Intelised ones and my concern is that I'm setting myself up for problems if I buy a current G5 xserve.
Does anyone know whether buying a current xserve will lead me up a blind alley in terms of hardware and software compatibility, system performance and cost.
Ta

Unlike the desktop and portable markets, where dual booting or running apps in virtualization are attractive, I can't believe that anyone will be doing the same with servers unless they are just playing around. Apple XServes are strong for AFP file services or SAN (XSAN) deployments, and Open Directory... but if you need a PDC, for example, you'll likely buy an Opteron or alternate Conroe platform w/o OS X as it will likely be faster at the same price or cheaper at the same performance level than Apple's hardware. Hardware performance of Apple gear, of course, has always been somewhat of a myth and effective marketing. However, not to say that the dependable hardware combined with the value of OS X isn't the more important issue.
A maxed out G5 XServe moves like a snail compared to the current maxed out Opteron systems, but they are CHEAP and they run OS X, which for some is a value, for others it is not. In the server market, Apple ends up being the budget solution, who would have thought?
To answer your question, I would buy now, because you are buying OS X, I presume. In the future, when the processing power jumps up 10 times, you can evaluate your system architecture and maybe then you can decide that you only need to buy 3 servers instead of 10... or something like that, but if the OS X server is going to meet your needs now, for the services you need to run now, you may not even get any appreciable value from a faster machine, especially if you have to wait for several months to a year. If your really scared about the hardware investment, buy a used G4 or G5 machine (like was mentioned), and install OS X server on it... maybe you only need the power of a G mini or something to tide you over for the Intel XServe? Or buy a G5 cluster unit... no one really needs the optical drive in most environments anyways.
The one thing no one has mentioned so far is that (at
least currently), we would not be switching from Mac
to Win without a restart. That's got to be a huge
PITA for a server on a routine basis.
I just got a single G4 xserve on ebay and max'ed the
ram (2GB) and 4x 180 GB drives for a mixed Mac and
PeeC network.
For what it's worth, there is still a lot of fight in
the old gal left for a small fraction of the cost of
the latest and greatest. 2 or 3 generations ago Macs
still offer a great value NOW.

Intel Xserve with Leopard Server 10.5.5 won't let me in via login

A power outage appears to have created some issues with my intel Xserve, running Leopard server 10.5.5
The System identifier light was blinking, so I booted up from the Leopard disk and found out that my mirrored internal array needed to be rebuilt. No problem, 4 hours later, I repair permissions on the mirrored internal array, everything gets "repaired". Change bootup disk to the internal 10.5.5 mirrored array and reboot. System Identifier light stopped blinking, things were looking good.
The login screen comes up and when I put in the admin username and password, the screen does the shake of the wrong login.
What's weird is, on my laptop I can use Server Admin, Workgroup Manager, and the screen sharing for the server....with the admin username and password.
So, I figure, perhaps the mirror rebuild requires me to reset the admin password. So, boot back up from the Leopard Server install DVD, run the password utility. and reset the main account password.
I change the boot drive back to the internal mirror, same thing. I'm stuck. I can't get past the login screen on the actually server....or via the screen sharing...and Server Monitor appears to be stuck at 'waiting for response'. I can, again, use Server Admin and Workgroup Manager on my laptop and make changes to the X server software....but I can't log into the X serve.
My webpage, wiki, etc....are all serving fine. But, I'd like to be able to figure out what I'm doing wrong...log back in and run super duper, etc.
Help...please...

Spent all day with apple support. They said it sounded like the LADP database was corrupted. They had me try to login as root, via an opendir account, etc. No luck.
So, they suggested I do a fresh install of the Leopard server on an external drive. Did that. They then suggested I use my laptop and the workgroup manager app to log in to the xserver, export users, groups and computers....and to copy over the library/collaboration folder to the external "clean install" of Leopard server.
Did that and followed the instructions to "relink" the metadata.plist files in each group, to the GUID to the groups in workgroup manager. First issue, they weren't different GUID strings.
Well, that didn't work...kept getting file not found error. When trying to access the domain.com/groups/groupname...it should've asked for authentication. And let me into that wiki...but no, apache error page.
So, they had me create a new "test" group....added a user. Start and stopped the web...etc. This didn't create a new wiki entry (when we replaced my custom index.html to the default index where groups/wikis/blogs populate automatically at the main). And, there's no new "test" folder in the library/collaboration files.
They then said "well, it must be because you don't have reverse DNS configured right, that's why the new wikis won't set up". I've contacted dyndns.com...but I don't think that's the problem.
So, I've rebooted my xserver to the internal drive. The wiki and blog is still there, still accessible the way I like....I still can't login to the xserver.
So, I'm wondering, if anyone knows a way I can boot up my xserve in the target drive mode, hook up my laptop and replace / swap whatever admin files so that when I boot up my xserve, I can login again.
There has to be a way to hard fix a hidden file? Replace a DB? Some awesome terminal command to get me in and fix the admin account / password....
Or, does anyone know if the reverse DNS issue applecare cites is legit? Doesn't make sense how, the same public ip and domain name, that's worked for some time...suddenly doesn't???
I'm hoping someone can help me.

Intel iMac Power / Overheat issue?

Hi there,
I have an Intel iMac from 2006. About 2 years ago it started to just turn itself off randomly as if there was a power failure. When it does, the only way to power it back up is to switch it off at the plug, switch it back on and press the power button (strangely) twice. I have noticed it seems to be temperature related - when my iMac reaches around 78C (which I'm pretty sure it should be able to handle fine?) it tends to be in the danger zone and at any minute can switch itself off.
I've got around this by using smcFan Control - which thankfully displays the temperature in the menu bar meaning when I hit around 72C I can whack the fans up to full blast to keep the temperature down. Being a sound studio computer - the hum of the fans really isn't ideal, but it at least makes my computer usable. However, I'm currently in the middle of a big project on Logic and I've had to turn my room into a fridge (window open-more clothes on) to be able to work on it as all the processing involved heats it up to 75C+ in no time.
I was hoping someone could shed some light on this or at least tell me if I am right in thinking that 78C is nothing really and the iMac should deal with it easily.
I have seen tons of posts regarding the G5 iMac power problems and similar problems with the intel iMacs - I've done all the hardware resets (PRAM, SMC, PMU) as suggested in these forums but nothing has helped.
I have had the power supply changed in the past (before this problem arose) as one day it just went kaput. Don't know if that makes any difference but I'm pretty sure that the problem started a little while after the replacement was installed.
Thanks in advance!

Intel Xserve + Xserve RAID + SCSI

I have a requirement for an Intel Xserve system that I can connect an Xserve RAID and SCSI tape autoloader to. It seems that Apple won't let me configure a system with a SCSI card and a fibre channel card in it at the same time, and repeated phone calls to them have yielded precisely nothing (very disappointed with the lack of professionalism and knowledge displayed by the Apple sales and tech staff on this matter).
Can I have such a configuration? It seems that I can only fit a fibre channel PCIe card in expansion slot 1 as it is too long to fit in slot 2 which is limited to 6" long cards. I've seen that Atto do PCIe SCSI cards but there is no mention on their site about whether they will fit/work in slot 2 of an Xserve and emails to them have gone unanswered.
If anyone has any info on this, or could point me in the direction of the info, I would be very grateful. Or if what I want isn't possible, ideas on how to back up a 7TB array without direct attached tape storage would also be appreciated.

Actually, having just looked at the store, Apple
don't seem to offer any PCIe SCSI cards, just a PCI-X
one with a PCI-X riser. Would this configuration stop
me using a PCIe card in slot 2?
Avoid the Apple BTO SCSI card like the plague. It's junk.
It's really a rebranded LSI Logic 22320. Ours never worked
right in our Xserve G5; we replaced it with an ATTO UL4D and
all of our problems went away. The right card for the intel
Xserve is the ATTO UL5D or UL5D low profile (both are PCIe).

Intel Xserve and kernel panic on high I/O load

Hi everyone,
Having added our 1st Intel Xserve to our server farm for test purposes we have encoutered several kernel panics on high I/O loads to Xsan volumes and standalone Xraid's.
Below is a portion of the system.log after restart.
The amusing part of this is that the crash reporter that suposed to log the reason for the crash crashed itself.
I was trying to use the new Xserve as a backup server but even with about 20% load on all 4 processors it will panic and restart.
Verdict: absolutley unreliable and useless if you need your Xserve to shuffle a lot of data around. The kernel drivers for the Apple FC card has also been changed which caused problems with our Archiware Presstore backup software.(kernel panic)
Looks like Apple is tampering with the multi core kernel of 10.4.8 on the Intel Xenon Processors at the moment and hasn't got it right yet. Well, we got one revision left to get this fixed before 10.5 comes out and that's still miles away from being usuable to say the least.
Thank you Apple, for selling your latest products that don't work as usual.
Any comments of similar experiences are welcome.

While I have found a few problems as well, I have gotten the intel xserve fairly stable (it did take a while and a lot of apple support calling)
I haven't had kernal panics, but I haven't been able to get the processors above 45% when doing compression. Also, I had some nasty lun masking problems with the fibre card which did result in corrpution of a HFS raid volume.
On the topic of xsan and the intel xserve, it is a BAD idea to try to install anything prior to 1.4.0. Had hangs, crashes and even corruption of the serial licensing daemon. Installing 1.4 and upgrading to 1.4.1 was a huge fix to those issues.
Overall, after a lot of work, it is working well, and does play back 100MB/s video extremely well off an xsan volume. Although, I would be fully content if I could get compressor's utilization of the CPU from 40 to 100%.

Intel Xserve No Activity Lights

Hey I'm trying to find out what could be wrong with our new Intel Xserve. It's fresh out of the box and set up on it's rack. We try to turn it on and it looks as if everything is well but the blue activity lights don't come on. We tried changing the startup method, and that doesn't work either. Anyone have any ideas?
BTW, this is my first post. Glad to be here!
Intel Xserve

Hey there,
Welcome to the board..
Had exactly the same problem 3 weeks ago. I pulled the thing completely apart and rebuilt and reset all the hard reset buttons inside. Still no joy. Had a spare's kit so replaced the logic board and away it went perfectly. Spoke to Apple techincal and they replaced the logic board from my spare's kit. They offered to swap the entire machine but time was not on my side so this was the quicked way to solve the issue. I did spend 1 hour on the phone to them to check and they agreed with my prognosis. Interested to know if you get any further with yours than I did - fingers crossed for you. Guessing there was a dud batch or similar.

Intel Xserve not using full CPU

When submitting a batch to qmaster, I notice my other g5 machines utilize almost all the processor, and on the intel xserve, all 4 CPUs usually max out at 40% tops. Is this a limitation, to be expected, etc?

Things do look clean - not familiar with all of the Processes, but some of the common "culprits" do not appear. Nice job in keeping these to a minimum. Most people have 60-80 going. Maybe someone else can look down your list and find something that can be eliminated easily for NLE work. I just don't see any potential problems, but remember I do not recognize some of those.
I like the Virtual Memory setting, with only one question: you mention a partition on the RAID 0. Why a partition? The reason that I ask is that Windows first sees your 2 HDD's as one (the RAID), then it sees your partitions as several. If accessing what it now thinks are 2, or more, physical HDD's, it's telling the controller to get the heads in a couple of places at the same time. You probably have a good reason for doing it this way, but it does throw up a yellow flag to me. Having the RAID managed by the MoBo chip is not the fastest/best, but is usually more than adequate. It does save on a US$400 RAID card with multiple channels/chips.
You have provided me, and others, with food for thought. I'll keep looking over your data, but just see nothing, except for the Page File on a partition, that might affect performance.
One test that I'd run would be a slight re-config on your Scratch Disks. I'd do a Save_As, or a Save_As_a_Copy for your Project. Leave your original totally alone. Do a test with the Scratch Disks set to "Same as Project." This will put them on the RAID 0. Then, perform the same operations and monitor the time. Unfortunately, you're investing hours into this, but you might get enough of a performance increase to justify it for future Projects. One way around the time, would be to do a "test" Project with shorter versions of similar Assets. Do all processing on that Project, as configured, and time the results. Do the Save_As, make the changes to the Scratch Disks, and process again. Any difference?
Good luck, and thanks for gathering the data,
Hunt

Intel xserve activity lights

First gen intel xserve from a long time ago, and was running 10.4.x
I remember it used to have 4 blue leds on the system activity lights on the front of the machine compared to the g5's 2 blue... (and remembered reading that had to do with the 4 cores).
As of recently, and haven't paid attention, I had to upgrade to 10.5, and then to 10.5.7 and the other day when I was downstairs, noticed that the 4 system leds were gone and it now just looks like the g5's when it's not doing anything. However, when I run compressor and have all 4 going full blast and look carefully at the front, it does still look 4 sets, but i havent been able to see just the four individual lights.
I've just been accustomed to looking at the front and seeing 4 individual blue lights, so was wondering if it sounds normal...

Hey there,
Welcome to the board..
Had exactly the same problem 3 weeks ago. I pulled the thing completely apart and rebuilt and reset all the hard reset buttons inside. Still no joy. Had a spare's kit so replaced the logic board and away it went perfectly. Spoke to Apple techincal and they replaced the logic board from my spare's kit. They offered to swap the entire machine but time was not on my side so this was the quicked way to solve the issue. I did spend 1 hour on the phone to them to check and they agreed with my prognosis. Interested to know if you get any further with yours than I did - fingers crossed for you. Guessing there was a dud batch or similar.
