Sleep or Shut Down with Mac Pro RAID Card?

I'll be gone for a four-day weekend trip, which is longer than the 72 hours claimed for the Mac Pro RAID Card battery. If I shut down and come back four days later, the battery will presumably be discharged. What will happen when I restart?
Asked another way ... is 72 hours the maximum amount of time that the computer should be shut down or do I simply restart and wait for the battery to recharge and the write caches to be re-enabled?
The FAQ for the Mac Pro RAID Card http://support.apple.com/kb/HT1346 talks around this issue, but doesn't say whether it is a good or bad idea to allow the battery to discharge for "... any length of time." Please review the appended excerpt from the FAQ and advise on whether I should sleep or shut down.

Question: Why does RAID Utility show a yellow light and report the status "Write cache disabled"?
Answer: The write cache is disabled automatically so data cannot be written to RAID volumes when the battery charge is not sufficient to back up cached data for 72 hours. This message is normally encountered when a RAID Card is used for the first time, when the battery enters a conditioning cycle once every three months, or when a computer with a RAID Card installed is shut down for any length of time.
If your RAID card's firmware is M-2.0.3.3 or later, or E-1.2.2.4 or later, you can use RAID Utility to force-enable the write cache while the battery conditions itself. Warning: If you enable the write caches before the battery is fully charged, you might lose some data if the power to your computer is interrupted.

Thanks to everyone who replied to my message. I did a proper backup and normal shut down on Wednesday night and restarted on Monday morning. That was over 100 hours later and certainly more than the battery is specified (72 hours).
When I restarted on Monday morning I noticed ... no change! The battery was fully charged according to the RAID Utility, I received no warning messages, there were no new events in the RAID Utility log ... it's as if the extended shutdown never occurred.
So, an extended shutdown appears not to be a problem and I won't worry about it again, not even on my next extended shutdown for three weeks at the end of the year.

Is the Apple Mac Pro RAID card (v 2.0) compatible with the Mac Pro (v. 1.1)?

Hello,
Just wondering if any of you experts know if the Apple Mac Pro RAID card (v 2.0) is functional with the Mac Pro (v 1.1)?
I have an original Mac Pro and a new (black) Mac Pro RAID card. I would like to know if I can get any functionality.
I initially thought that the only difference was that the later RAID card did not have the same limitations on the HDs. I am aware that my original Mac Pro has a SATA II bus rather than a SATA III bus- but I am hoping this will not present any issues other than speed.
I am currently using Disk Utility for a striped software RAID (0) but would like to move to a parity hardware RAID (5); hence the purchase. If this isn't possible I'm not overly concerned as I managed to get hold of the RAID card for next to nothing so thought I would take the chance.
Any feedback would be appreciated as everything I've dug up online over the past few days has been a little inconclusive.
Julius.

The black-substrate card requires a 2009 or later model, and works only in slot 4, which has a special connector for it there.
The blue-substrate card requires the ipass cable and connector feature in the 2008 and older models.
These cards are both showing their age, and limit drive size to 2.2TB each. Their data-backup batteries have been extremely troublesome. You should probably look at other alternatives as well.

Shutting down my Mac Pro Retina properly?

When I shut down my Mac Pro, I close all apps except the Finder. I've noticed that sometimes when I start up again, the Apple logo and the loading bar don't appear, and when I go into the desktop, the Finder is still open on the folder it was on before I shut it down the last time. But there's still the normal start up sound. I think this is because when I see the screen go black, I close the laptop screen straight away, and it hasn't truly finished shutting down yet. I've been trying to wait for a minute before closing the lid after the screen goes black, and it's been working: the next time I start up my Mac the Apple logo and loading bar appears as usual, and when I get on to the desktop, the Finder isn't open on anything.
My question is, is it really bad for the Mac if I close the lid before it properly shuts down, and I leave it in a kind of limbo state before I start it up next time? Because sometimes I'm in a hurry and I don't have time to wait a minute before closing the lid.

Hello animefan4eva,
After reviewing your post, it sounds like you were trying to shut down the computer but closed the lid befor it finished. I would recommend that you read this article, it may be able to help the issue.
Mac notebooks: Wait for your computer to fully shut down before closing the display - Apple Support
If you close the display on a MacBook Pro, MacBook, MacBook Air, PowerBook, or iBook while it is shutting down, the computer may not shut down properly.
Thanks for using Apple Support Communities.
Have a nice day,

Mac Pro RAID Card - RAID 5 capacity with 4 drives

Greetings everyone,
last weekend, I installed a Mac Pro RAID card in my Mac Pro, gave it 4 Samsung 1TB disks to play with and set up a RAID 5 array on it. However, the capacity is less than what I would have expected (expected around 2.8TB and got 2.38TB).
After some searching on the Apple Support pages, I found this ...
http://docs.info.apple.com/article.html?artnum=306212
... support article stating that in a 4 column RAID 5, the capacity indeed could be less than expected due to "data placement and layout techiques".
Does anyone know the technical reason behind this? Any other RAID 5 I know, hardware or otherwise, does not have this quirk.
Is there any way to work around this? If not, are there any other, comparable RAID cards that get this right?
Thanks in advance,
-sai

Hi sairath;
With RAID 5 one of the drive is devoted to Parity so that the data can be restored in case of a drive failure. Hence you are only going to see the space for three of the drive so your results sound pretty normal.

Mac Pro RAID Card and Western Digital drives

I'm having huge troubles with these items.
I first installed four WD7500AYYS (Raid Edition) to build a RAID 5 and install Leopard on it. At this point, one of the drives was probably DOA and didn't show up in the bay. I then reinstalled the Seagate that shipped with the machine, then proceeded to create another enhanced JBOD raid with one of the WD drives. After a couple of seconds, RAID utility reported an error (disk about to fail and such). I then tried with another one. The process ended with a kernel panic after two hours, while RAID utility was still marking the drive for enhanced JBOD. That disk never show up again, in any bay.
At this point, I'm left with two WD drives. I can't get past the creation of a RAID set with them, no matter what. Either RAID utility reports an error, or it says the disk has been ejected, or it keeps create the RAID for hours... The later usually ends with a "force quit", or a force shutdown. During these attemps, the RAID card went missing once, then it appeared again on the following reboot. The RAID battery, which was fully charged at first, is now being "repaired" (charging ?).
I then ran AHT to see whether there was something wrong. No errors reported.
Because all four drives were Raid Edition, I thought this could be the root of the problems. So I bought a Caviar SE16 (WD5000AAKS). To no avail. It fails too, in the very same way. And now it no longer appears in any bay.
The last step I took was to remove the RAID card (connecting the iPass connector to the motherboard). Out of the five WD drives, only two RE2 (the two that still show up with the RAID card) do appear in disk utility. But disk utility never ends "writing the partition map" or "preparing for initialization".
By now, I end up with five WD drives that appear to be just dead, as if they were killed by the RAID card trying to RAID them. The only drive that works, with or without the RAID card, in any bay, is the Seagate. I didn't try to fiddle with it though (I'm reluctant to format it just to see whether I can create an enhanced JBOD raid with it).
So the question is, are Western Digital drives compatible with this RAID card ? If they do, then how a RAID card can kill them in such a way while keeping the Seagate alive ?
I'm lost in conjectures. I don't even know if/how I can bring all the WD drives back to life. I'm not sure the RAID card is faulty, I've already lost a lot of time and money, I'm not willing to buy yet another drive to see it fail too, and my Mac Pro is kind of useless as I don't want to spend time on installing/configuring everything I need on a drive that is bound to be replaced by a larger RAID 5 array.
Any help is appreciated. Thank you.

Someone yesterday or Friday, had a system with 4 x 1TB drives and Pro RAID, but in their case, it was determined later Saturday that drive bay #1 was not functioning.
Hopefully these fully retail drives, not OEMs, and I would think they are fine. They are what I would use (Sonnet Tempo only supports RE of the WD drives). Someone else, Danish?, had 3 out of 4 WD drives were DOA.
I've never had trouble buying over a dozen from OWC, so it does seem odd.
If you have SoftRAID 3.6.6 I would use that to zero the first and last 100 sectors, or you can begin to zero the whole drive and cancel at any time, just to check the health of the drive and that it can zero and not produce I/O errors.

Originally, only Apple drives were supported. My understanding was that this changed. But the only article I found in KB dates back to Aug '07:
Question: What drives does Apple support with the Mac Pro RAID Card and the Xserve RAID Card?
Answer: +Only Apple drives are supported with the Mac Pro RAID Card and the Xserve RAID Card.+
My understanding that 3rd party retail drives such as WD RE2 750GB, Seagate, Hitachi were supported as well since the article was written - and I can't find where I read that, but sure that I did, as this was discussed in the past.
I'd like to find an official article. Even my friend Google was helpless

Leopard/Bootcamp/Mac pro RAID Card

The last two bullets in the "More Info" section of Apple's Mac Pro RAID card read as follows:
• The Mac Pro RAID Card is required when selecting 15,000-rpm SAS drives.
• The Mac Pro RAID Card supports Mac OS X only.
Five Apple tech reps have told me I can run Leopard on a striped array of three 300GB SAS drives and then, via Bootcamp, use the fourth independent 300GB SAS drive to run Windows XP. I ordered a $10,000 G5 tower on this premise and now, today, a sixth Apple tech rep tells me it cannot be done. Each time I've called, I get a somewhat different answer. Does anyone have actual experience with a G5 such as this? Is there a third party RAID card that will work? If necessary, I still have time to cancel my order. Why would Apple build a RAID card that is not compatible with a most important feature of Leopard--Bootcamp? I don't understand their philosophy. They seem to work at biting the hand that feeds them.

Kappy, thanks for taking time to try to answer my question. I'll state it more clearly.
At this moment I'm typing on a 3 GHz Dual-Core Intel Xeon machine with four 500Gb drives. Three drives are configured as a RAID 0 Volume running Leopard. The fourth INDEPENDENT drive is partitioned via Bootcamp into two bootable volumes--one with Leopard and other with Windows XP Professional. For the new machine I would like to purchase, I never intend to run Windows from a RAID volume. My beef with Apple is that their high performance 15,000 rpm SCSI drives require their RAID card to function, whether it be in a RAID set or independently. Their interface to the motherboard is through the RAID card. Apple has not written Windows drivers for their RAID card. Consequently, if I intend to run Windows on their latest Mac Pro, I cannot install the high performance 15,000 rpm drives. I simply would like to configure the new machine the same as the one I have now, which is three drives combined in a RAID 0 array running Leopard, and the fourth drive remaining a stand alone for Bootcamp to partition into two bootable volumes--one with Leopard and one with Windows XP.
In summary, there is no way to use Apple's highest performance Mac Pro in a Windows environment. I think that's inconsiderate of Apple. I would like the performance of 15,000 rpm SCSI drives (RAID or not) but I also need Windows XP. I'm sure many others will face the same dilemma. Apple should give this matter a high priority and churn out the sorely needed drivers. So back to my original question--five Apple tech reps said I can configure the machine as described above and it will work fine--the sixth rep said there is no way it can work, because their card cannot run Windows. Who should I believe. I don't want to make a ten-thousand dollar mistake.
P.S. The configuration shown below is for the machine I hope to purchase, not the one I'm using now. This one is a 3GHz Dual-Core Intel Xeon Mac Pro.

When I shut down the Mac Pro, it restarts

Has anyone run into this issue with their Mac Pro? When I shut down the computer (either via the Ctrl + Option + Cmd + Eject or the Shut Down command from the Apple menu drop down), the Mac Pro will simply restart and take me back to my log-in screen.
At this point, I can hit the shut down button on the login window and it will shutdown, but this is annoying, a waste of time, and unnecessary.
I have tried performing an SMC reset, but it has not resolved this issue.
Specs: Mac Pro (2010)
3.33 GHz 6-Core
(2) 2TB Internal HDD
12GB ram
ATI 5870 graphics card (1GB)

I have noticed the exact same behaviour. It only happens when I have something plugged into one of the front USB ports (example : external HD, USB key)
Apparently the system crashes during the shut down process, and then reboots.
Unfortunately, I have not yet found a solution

Mac Pro & RAID Card configuration

hello-
i've got a 2 x 2.26 Quad Core Xeon Mac Pro with an Apple RAID card in it
1 x 1TB system drive
and
3 x 2TB media drive for video
question: can i have the system drive separate from the RAID card and just create a 6TB RAID0 array for the media drive?
i've heard that the system drive should be part o the RAID (currently it's its own JBOD RAID, so NOT part of the 6TB array) but I can't see how to do this
any help/advice will be much appreciated.
thanks
david

If you have a RAID card installed and the drives are in their trays, they're all going through the RAID card (for MLB interface purposes). You could have a single drive setup as the sys drive and then the three drive RAID 0 set. The card will support RAIDed and non-RAIDed disks. I currently have a MacPro with a RAID card installed, yet all of the disks are setup with the original OS-based RAID configuration (will be switching soon as the RAID card was just installed). You have plenty of choices and what you're wanting to do is totally doable with or without the RAID card, as it could be done in the OS via Disk Utility.

Does a Mac Pro RAID card affect a Sil3132 PCI-E Card ?

I've got a Mac Pro with the Apple RAID card (Slot4)
I've put a Sil3132 PCI-E eSATA card into Slot 3.
I can load drivers (v1.1.9 Silicon Image), and see the eSATA card in the System Profiler
But I cannot get it to see the hard disks connected to the eSATA bus.
The cables and disks work with my other Mac that has eSATA but not on the Mac Pro.

I've got a Mac Pro with the Apple RAID card (Slot4), I've put a Sil3132 PCI-E eSATA card into Slot 3. I can load drivers (v1.1.9 Silicon Image), and see the eSATA card in the System Profiler.
Hi,
I have seen system conflicts occur when both the Apple RAID card and SI drivers were installed. It may also be another driver that is causing the issue. To troubleshoot this issue I would install a fresh copy of Mac OS X on a spare HD using the Apple DVD and boot from it. Next, install the SiI-3132 1.1.9 driver, reboot and see if the issue still exists.
If the issue is resolved you will know something else is causing the problem on the regular boot disk.
Another possibility is that the SiI-3132 card has the RAID BIOS flashed to the card. This will usually occur if the card is purchased from a PC vendor. In that case, the card may not work unless the Mac SiI 3132 32-bit universal SATARAID5 driver is installed OR the card is flashed back to BASE BIOS.
You can find the drivers here:
http://www.siliconimage.com/support/searchresults.aspx?pid=32&cat=3
Unfortunately, there is no Mac driver uninstaller provided by Silicon image and the different driver versions install several files in different locations. This is why it pays to buy the SI controller from a Mac based reseller that knows what BIOS is installed. If you did not purchase from a good Mac reseller then it is best to test the card with a spare boot disk that you can erase if the wrong driver is installed. I would not want to mess up my main boot disk with these driver tests
Have fun!

Dying Batteries on Mac Pro RAID card

We are using three of these cards and two of them have completely defunct batteries. I am not sure why this happens considering that we have only used them for approx 6 months. The life of them is remarkably short for a rechargeable.... Due to a number of complicated reasons, our warranty with Apple is out so we are not able to do this as a warranty claim but I don't seem to be able to find a means of purchasing these apart from a 3 month wait here in Macau. Does anyone have any advice on where I should go from here. Of course, they operate fine without the batteries but we need them as a form of redundancy...

Hi
Welcome to Apple discussions
You can either try contacting Apple HK to purchase new batteries, is that who said it was a 3 month wait?

Mac Pro + RAID Card = No Bootcamp?

I have a Mac Pro with a RAID card in it and 4 drives connected to the RAID card. As is pointed out in the Bootcamp manual, the RAID card won't work since Windows does not have drivers for it.
Being persistent, I figure I just add a 5th drive to the system. I did so using one of the ODD-Sata (Optical Dist Drive SATA) ports (the extra ports on the Motherboard), only to find out that Windows still does not see this drive.
Now, there are supposed to be 6 SATA ports on the motherboard, right? But I cannot locate any of the other ports, I only see the 2 ODD-SATA ports. Does anybody know if it is possible to hook my 5th drive up to one of the other SATA ports and so still get Bootcamp working?

I got the same cable from Newark. It was a bit of an adventure to get it installed, you need to take the plastic housing of the "fan assembly" out, which you can do after you remove the cover of the heat sink fans.... there is some info on the web on how to take apart your Mac Pro, just search for it.
The result is GREAT! I got some Sata female to female connectors at Newegg, which allows me to attach a long Sata cable to the short stubs of the Molex 3009 cable (that I got from Newark). I also got a power cable converter, old style to sata power plug.
After plugging in an empty Sata drive, copy your system onto that drive (or do a fresh install, whatever). Then you can boot from your new drive, not the RAID. Once you've done that, you can use bootcamp as it is supposed to work. Windows XP installed without a hitch. The partition with the copy of your main system is not a bad thing to have either, incase you mess up your main system. I don't think you could wipe it, since I think (but am not sure) that it is needed for booting. You could probably shrink it to something tiny if you like.
So, problem solved! Now I have the possibility of hooking up 4 more drives....

Never heard that advice before. The kb certainly does not say that.
Big difference from your statement compare ""Apple does not recommend leaving your portable plugged in all the time."
I think using the battery regularly is a better interpretation.
I would submit that is the way most people use their Portables, close the lid.
You absolutely misunderstood I referred to BOTH "on power AND in sleep mode"
     not to: "closing the lid ,... sleep mode"
Using the battery regularly can mean anything as a generalization.
That advice on parasitic charging is correct.   Which referres to BOTH in sleep AND on power...   not however to merely "in sleep mode"
There is no etrecheck for parasitic battery charging,   ..... NOR is there any such check for both:
1. fast discharges
3. low discharges
As such that battery information you provided above doesnt report bad abuse / misuse of a battery.
Nor does / can Etrecheck report on physical abuse of any macbook, logically.
Battery abuse / misuse is a type of physical abuse, chemistry of the battery abuse, however its internal.
I did not say the KB article said that,    what it says:
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
So, you misunderstood.
Apples recommendation refers to micro-cycling the battery and to parasitic charging in the above quote, that it doesnt elaborate on the specifics of same
is irrelevant.
The implication from same is exactly this
*If you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The only quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
Bad discharging or battery use conditions:
Heat (due to environmental conditions or due to rapid discharges from heavy use = gaming / video editing)
Rapid discharging of the battery frequently causes chemical changes over time in the battery leading to decreased capacity and resistance of current flow.
The very worst use of your battery is often draining the battery very low, and worse still letting it remain in such a state.
*Most long-term rapid damage to the battery occurs from discharging it with high loading (gaming) conditions but paramount is avoiding deep and frequent low DOD (depths of discharge) in use.
Undesirable charging or charged conditions:
High perpetual SOC (state of charge), where the battery is always or very often connected to charge
Parasitic loading where the battery is both usually on and charging or worse both always charging and in sleep mode, since this induces mini-cycling of the battery.
Bad general handling conditions:
Temperature use conditions when either too hot (95F and above) or too cold (50F and below)
Storing your battery away with a low charge (40% and less) long-term.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term.
Ultimately counting charge cycles is of little to no importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.

I want to shut down my mac pro (retina display) but when I try to it says that in the finder some operations are still open and i should go close or cancel them. The problem is that I have nothing running or in use. Is it the remote disc or what?

nothing seems to be wrong, so i am a little unsure of what the problem could be..

Press Alt, Command and Esc keys, select Finder in Force Quit and force close it. Then, you will be able to restart. You can also try to press Control, Command and Eject keys

Mac Pro RAID 0 setup with bootcamp

I'm about to take the plunge and buy a Mac Pro as soon as I get the money (or credit) to. There have been things here and there that have turned me off but I found ways around some concerns, but this one I haven't been able to find.
I am a musician and want to utilize raw power that Mac does so well with. But unfortunately my DAW of choice doesn't support OS X. I hate Vista, I never upgraded, I stayed with XP but have been willing to change to OS X with XP as well, to get the best of both worlds. Then i find my DAW doesn't support XP 64 bit so i am going to have to use Vista 64-bit (bummer).
What I haven't been able to figure out is if it is possible to run a RAID 0 of the windows OS and all its data. The Mac Pro RAID card doesn't support any Windows OS so i am wondering if there is anyway possible to get the Windows OS in RAID, any good hardware or software that will accomplish this. Like if i get the Mac Pro RAID cad, is there a good software or hardware RAID that will allow me to install windows in a RAID 0 configuration?
If its possible I would have no reasons to not move over, but I really need to have my RAID setup in windows since I am using latency sensitive disk streaming programs that need to stream files in the GBs
Also could I just opt out for the Mac Pro Card and get a generic RAID card that supports both Windows and OS X? And if so any recommendations?

Apple is not very upgradeable. It would cost me more to upgrade the cpu than buy new (though can get a good $$ on my system - in part because it runs the prior version of OS X 10.4 "Tiger". New systems will only run the current/latest OS, you won't be able to run Leopard if a system comes with Snow. The graphic choices and upgrades can be lame. It is almost a closed box.)

Shanghai’s 16 cores outperformed Dunnington’s 24 cores (or 48 if Hyper-Threading was used) by 6.5% or 8.8% depending on whether or not IBM or Dell’s chipset was used. But if we normalize that out per core, Shanghai outperforms by 59.8% (per core) or 63.2%. That is unbelievable!

I noticed Apple isn't selling the Mac Pro's with raid cards anymore, so it makes me wonder of Mountain Lion is compatible with my Mac Pro which uses the apple mac pro raid card. Anyone know??

Thanks Kappy. I'm more interested in the RAID card compatibility. Anyone else know?
