Is my fiber channel card failing?

Is there a way to test a fiber channel card.
I believe mine is failing, but don't know how to confirm.
Every few days the fiber channel links to my Xserve Raid go down.
Raid Admin shows no trouble.
Usually it comes back after rebooting the Xserve.
This is making things extremely difficult, please help!

Here's my situation. At home we use 3 different Macs
all on the local wireless Airport network. One is a
G5 that I use in my home office, another is my wife's
G4 laptop and the other is a relatively new iMac - it
is the iMac that is a problem.
Is this a new Intel iMac?
Are you using WPA?
Some Intel iMacs have issues connecting to a WPA encrypted network which results in a slow network connection.
I have read that there is an issue with the Intel iMac and wireless speeds when using WPA?
Are you using WPA?
What happens if you change to WPA2 ?
Or WEP?

Late PM G5 quad and Fiber Channel card

hello, will working on my late powermac G5 quad the Apple Fibre Channel card MA462G/A???
i will connect the apple raid...
the description implies that this card is Intel only...
when not, then what card you recommend?
thanks

My Quad has the 6600, 4.5G RAM, and 2 - 250G drives, Airport/Bluetooth. I loaded the system by running a process which runs 4 threads randomly moving 1M chunks of RAM around (from a block of about 3G), and verifying the memory isn't corrupted. Activity Monitor shows the CPU at 0% idle, my test program is using about 380% CPU. Processor is set to Highest in Energy Saver prefs.
I'm using a Kill-A-Watt. Running as described above, wattage is displaying 426.
I'm might be able to get it to use a few more watts by exercising the drives, but not more than about 20W.
My point is that the Quad itself doesn't use as much power as some think.
The UPS sure makes it easy to add the Kill-A-Watt without rebooting.
Quad G5 2.5Ghz 4.5GB 2x250G, PB 15" 1.5Ghz,80G,1.5G Mac OS X (10.4.6)

I am running Xsan 2 with primary/backup meta controllers and both of my servers showing no link on the Fiber channel cards....have 2 G5 dual 2.3 GHz systems, 6 gig ram, 10.5OS. and PCI-X FC cards. QLogic 5600 switches. Looking for the non-obvious

They have been up and running for over a about a year on XSAN 2 and all of a sudden started having problems with data transter and then won's connect anymore
Thanks

amd 64=12a @12V
ati 9800=7.5~10.5a @12V (assuming 90~125 watts) a max load,
a 9600 ir nvida 5200 used far less power
so your already at 18a with no fan,s no hd, no cd,no dvd ,no mobo chipset , no mem, no sound..etc
If you exclude the motherboard, memory, etc like you did there, the amd 64 draws 7.2A @ 12V.
90~125W for an ATI 9800?! [irony]Are you working for a PSU manufacturer or what?[/irony] That's just absurd.

4Gb Xserve Raid Card to 2Gb Xraid Fiber Channel

Greetings All,
Does anyone know if a 2x4Gb Fiber channel card will auto-negotiate down to the 2Gb level of my Xraid?
Thanks,
-dave

Yes it does. I've done it and the newest Xserve is plug and play with the old Xserve RAID.

Use of Fiber Channel in Boot Camp with Windows XP

Hi All,
I am looking at getting a Mac Pro for a project that requires I use Windows XP under boot camp and wanted to know if there were any problems accessing a RAID array via the standard 4GB Fiber Channel adapter available through apple. I don't need to boot off this drive, just access data on it. Not a lot of information on the official apple support pages...
Thanks!

Yes, XP will be able to detect the expansion card if you download the appropriate drivers online. When bootcamp was first starting... this article circulated http://docs.info.apple.com/article.html?artnum=305401... summary, you should remove the fiber channel card before bootcamping. Since then the software has gone through the proper modifications that you can just plug the card in, boot into windows, and download the LSi driver for XP.
So you'll have no problem setting this up.
Cheers
Ron

Apple Fibre Channel card & kernel panics

Hello
i've just installed a new Apple Fibre card 4gb 2port, in the top PCIe slot running at 8x - fine. once installed I am getting erratic and random - kernel panics. I've removed the card and the panics stop.
enclosed is a panic log -- any advice or noticeable incompatibility?
really need to get this connected to my fibre san - so any help appreciated (or any other card that might work?

Welcome to Apple Discussions!
It is possible you got a faulty card, or that the card was not properly seated, or that it doesn't have enough space in the slot to stay cool with other items in the slots. Try eliminating the latter as a possibility if you have additional PCI cards. Also if you have no other PCI cards, try changing slots to see if the slot on the Mac Pro is damaged. If all yield bad results, did you happen to migrate your data from a PowerPC Mac with the Migration Assistant? That can cause bad drivers to get migrated, and if there was a fiber channel card driver for the old Mac, it might be causing problems.
If not, then I'd assume you have a bad card, and I'd replace it.

Mac Pro w/ Fiber Channel, Can it sleep with XRaid attached?

I wanted to know if the new mac Pro can fall asleep when it has an xraid attached via its fiber channel card.
My Dual 2ghz G5 does not, this is why I'm asking.
Your comments are welcomed.

Not sure, but on the 'old' one,by design, NEITHER the Fiber card and Raid card will allow 'doze' but not 'deep sleep' of the Mac Pro in order to sustain connectivity, battery charge and redundancy, respectively.
I doubt that changed.
Anyone?

Fiber Card failed

Dear Guru
Hope you may give me some information about the problem.
Our company SAP is ECC6.0 running on AIX 5.3 with oracle database.
Few day ago, the server log showed one of the fiber NIC card on our development server was failed. I already arranged the hardware vendor to come down to change the device next week, but before that, may anyone confirm with me whether the hardware key will be updated by replacing a new fiber NIC card? And do I need to reactiviate the SAP again?
Thanks
guodong

Hi,
If fiber card fails then hardware vendor has to play the key role. After he replaces the card he may have to change the WWN number at the EVA side . One he was able to mount the file systems with the same data then there is no need to check at SAP side. Only thing yo have to monitor the SAP application completely. Also check the run the DB verify in DB13 for any block corruptions.
Thanks,
Chaitanya

XSERV RAID FIBER CHANNEl

We have XSERV RAID MODEL A1009 with 4 Hard disk RAID 5.
Now I have installed CISCO 1000Base SX Module in 3 COM Switch & other same Module in XSERVER RAID. Now XSERVE RAID & switcted with Transeiver cable. Now I check RAID ADMIN TOOL FIber Channel Option the links shows down.
Let me know what is solution. Please also let me know how can I know that fiber link is up if any way.

Finisar makes a nice SFP to LC transceiver (available on the Apple Store for $99.95 for 2 Gbit and $119.95 for 4 Gbit) that you can use in the Xserve to allow it to accept LC optical cables. You'll need 2 of these, and then you can hook up LC optical cables.
I'll echo the other post -- be aware those ports are for fibre channel communication ONLY. You must hook it to a fibre channel card (HBA) in a host, or to a fibre switch (i.e. Cisco MDX 9000 series). You cannot hook up a network connection to those ports -- Xserve RAID provides data ONLY over fibre channel, it is not a NAS device. You must connect it to a host which can re-share the data over Ethernet, for example Xserve RAID with OS X Server which can reshare using AFP, SMB/CIFS, NFS, FTP, DAV, and more.

Fiber Channel Error

Having a problem with the Fiber Channel on our Xserve RAID. The Admin Utility says that Fiber Link 1 is Down (and it's red), but everything is properly connected, I have restarted several times, unplugged and plugged back in, done a few upgrades to the firmware and it still says it's down.
Any ideas?
Thanks.

I swapped the Fibre cables, controller and reseated the card in the mac. Still nothing. I noticed under the Hardware Overview that there is not even an option for Fibre Channel. Is this due to the system running 10.3.9?
Thanks.

Kernel panic when connecting fiber channel

I recently inherited an Xserve RAID. I have an LSI fiberchannel card in a G4 running 10.5.5.
Anyway, I updated the firmware to version 1.5 and now everytime I connect the fiber channel cable I get a Kernel panic instantly and have to force power down.
I've tried 3 different cables on and every port on the mac and the xserve and get the same result.
any idea what's going on?

Well, i just upgrade to 10.8 and its solved the question.

My graphic card failed but passes the recall test - surely Apple would replace it? How wrong can you be!

Even though I had read about the product recall on some iMacs, mine had never had an issue, but to be safe, the plan was to take it to an Apple store to have them test and replace it.
A week ago, on occasion, the screen suddenly started going completely gray, everything else seemed to be working fine, and any apps running would continue to do so. Without being able to see the screen, the only options was to power it down, run any diagnostic test and start normally. It passed pro tools tests, with no warnings so I thought it could have been a software issue. After many restarts without anything else plugged in, the iMac appeared to function for maybe a day or so, but gray screen whenever it wanted to.
So I called Apple, they told me to get it into a service centre, and they would do further tests. Whilst on the phone to the engineer, my iMac with the gray screen suddenly refused to power back up. The engineers tell me that the graphic card fails any benchmarking tests with corruption and the same gray screen issue, so it looks promising yes? No. The specific tests that the machine must fail for the recall - passed.
Having spent almost an hour on the phone to a Apple senior advisor today, he tells me that it is not covered by the recall !!
The machine is one of the matching serial numbered machines in the recall, it has suddenly developed a graphic card issue that leaves the machine unusable, it suddenly started having this problem within weeks of the recall being announced - It has the faulty card in it, it has the fault - yet it does not qualify?
Can someone please tell me what I could have done to get this card replaced without the estimated £250 charge to get my machine running again.
I am a die hard Apple enthusiast, I have converted everyone I have been in contact with to purchase from them for their legendary customer services and yet feel perplexed as to what I should do next.
My first reaction is to raise a big fuss about the situation at an Apple store, but I can't blame them too much if my machine does not match the recall criteria - but come on, it can't be a coincident that this card has failed now, can it?
What do I do next. I don't want to take my machine over to proper Apple store and raise a fuss, that would be counter productive. But really Apple
Anyone have a suggestion - would you buy another iMac that could have the same problem and get the same response?
To any Apple engineers out there who can look at a case number my ref number is 500592345, apparently there is a lot of info in there, but nothing that will help me!

Apple engineers do not participate here. The only replies you will normally get are from people who are, like me, just fellow users, and there's nothing any of us can do to intervene in this matter.
If Apple says that your system is not covered by the recall, there's not much you can do. You can try taking your system to an Apple Store and politely - do not "make a fuss"; polite but gently insistent is much more likely to get you useful results - ask for assistance. Or you can call Apple tech support, ask to speak with customer relations, and explain the situation to them and request coverage under the recall program.
If all that fails, though, then you're probably at a dead end and will need to pay for the service if you want it done.
Regards.

Problem with fibre channel card and raid system after upgrading to 10.4.7

Hello, I have a problem with our Xserve G4 DP. After the installation of 10.4.7 everything works fine exept our fibre channel card. This card is connected to a Hitachi Raid System which worked fine over a year. But after the update the volume was no longer mounted. I even reinstalled the server to 10.4.4 and no sign of our raid volume. Using the apple fibre channel utiltiy 2.0, I see that there is a connection - but still the raid volume is not mounted. When I restart the server the lights on the back of the card are shortly flickering and sending some packets to the raid system but that´s all. Has anybody an idea?
Greetings from Heidelberg

Xserve G4 DP 1 GHz Mac OS X (10.4.6) Mac OSX Server 10.4.7

You could re-update, by downloading the 10.4.7 Combination Updater from Apple.

What are the host network requirements for a 2012 R2 failover cluster using fiber channel?

I've seen comments on here regarding how the heartbeat signal isn't really required anymore - is that true? We started using Hyper-V in its infancy and have upgraded gleefully every step of the way. With 2012 R2, we also upgraded from 1gb iSCSI
to 8GB Fiber Channel. Currently, I have three NICs in use on each host. One for "No cluster communication" on it's own VLAN. Another for "Allow cluster network communication on this network" but NOT allowing clients, on
a different VLAN. And lastly the public network which allows cluster comms and clients on it (public VLAN).
Is it still necessary to have all three of these NICs in use? If the heartbeat isn't necessary any more, is there any reason to not have two public IPs and do away with the rest of the network? (two for fault tolerance) Does Live Migration
still use Ethernet if FC is available? I wasn't sure what all has changed with these requirements since Hyper-V first came out.
If it matters, we have 5 servers w/160GB RAM, 8 NICs, dual HBAs connected to redundant FC switches, going to two SANs. We're running around 30 VMs right now.
Can someone share their knowledge with me regarding the proper setup for my environment? Many Thanks!

Hi,
You can setup cluster with a single network but that leaves you with single point of failure on the Networking front, it is still recommended to have a heartbeat network.
Live migration would still happen though Ethernet, it has nothing to do with FC. Don't get confused, you had iSCSI for storage which used one of your VLAN and now you have FC for your storage.
Your hardware specs looks good. You can set up the following networks -
1. Public Network - Team two or more NICs (based on bandwidth aggregation)
2. Heartbeat Network - Don't use teamed Adaptor
3. Live Migration - Team two or more NICs (based on bandwidth aggregation)
Plan properly and draw guidelines to visualize and to remove single point of failure at all points.
Feel free to ask if you have some more queries.
Regards
Prabhash

Communication channel is failing

hai friends
the communication channel is failing as it is not able to pick a field it is showing the error as follows
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload: date_processing: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload: date_processing

Hi Sandeep,
i dont think, it can be helpful to open 3 or 4 threads for one question. It is quite difficult to follow the point of discussion if it is divided to more than one thread, additional it shows impatience.
You should invest in more details of one thread: Where did you pick the message up? How does your sceanrio look like? What does not work? What did you try? Where are your questions?
