Raid firmware compatibility with the OS

We would like to update the firmware on a four year old xserve raid that is attached to Xserve running OS X 10.2.6. The OS will be left at its current level and we will just update the raid. The current raid firmware level is 1.0.1/1.16f. Our concern is with the compatibility of OS X 10.2.6 and the new raid firmware 1.5.
We have left versions as they are, because the server hosts millions of critical files and is used in a production environment. The raid is presented to the server as a software stripped raid 50 using all 14 drives. Because a software raid 50 is not portable we have been reluctant to tamper with the server environment.
Does anyone know of any compatibility issues or is raid firmware level independent of the operating system of the server to which it is attached>

The firmware on the RAID is totally independent of anything going on with the computer. You can update it to 1.5/1.5.1 and all should be fine. It doesn't matter what OS version you're running.
Be aware that if you're using LUN masking, that 1.5.1 removes that functionality from the GUI (so I'd recommend 1.5 in that case).
Also note the RAID 50 is portable -- if you moved the FC card and the cables to another machine it should show up properly.
In any case -- have a current backup before you upgrade that firmware -- that's best practice in any case.

I have an iMac with 10.4.11 and a Mac Air 10.6.7. Will the Extreme be compatable with the 10.4.11?

I have an iMac with 10.4.11 and a Mac Air 10.6.7. Will the Extreme be compatable with the 10.4.11?

10.4.11 Macs will have Kernel Panics when trying to use Dual Band Airport Extreme Base Station. There are a few forums here dealing with it. I just purchased an Airport Extreme Base Station and spent two days now figuring out why the old iMac G5 running 10.4.11 (Tiger) was Kernel Panicing. There is a way that I am testing now that seems to be working. I will post the link in a minute when I find it. Other solution is to upgrade to 10.5 .
Here is the post
Aug 22, 2010 2:09 PM (in response to Acin)
Greetings... I have just found a resolution to this problem, at lease if you're using one of the newer Dual Band Airport Extreme base stations. This fix was provided by an AppleCare representative named Rebecca, and I am deeply in her debt. To review: MY PROBLEM - After installing a new Dual Band Airport Extreme in July 2010, I began to have frequent kernel panics with my older laptops running Tiger (10.4.11). My newer Intel/Leopard MacBook Pro ran fine with the new base station, but these older Power PC Macs with Tiger just crashed again and again. Pulling the Airport Card was the only fix. I tried every conceivable software and network fix; nothing helped. THE SOLUTION - The AppleCare rep talked me through this, but I'm pretty sure this was the procedure. Please note that I cannot guarantee that I have not forgotten a step! But I am fairly sure this is it. (If an Apple specialist is reading, please check this!) Keep in mind, this will only work if you have a dual-band Airport base station. I performed this on a Mac Pro running OS 10.6.4, with Airport Utility version 5.5.1 and firmware 7.5. 1. Launch Airport Utility.
2. With the dual-band base station selected, click Manual Setup.
3. Click the Wireless tab.
4. Click the "Wireless Network Options" button near the bottom.
5. Check the box that says "5 GHz Network," then enter a new network name in the Name field. (Your existing network name appears there now. Just delete it and type a new one.)
6. Click Done. That dialogue will close.
7. Now click Update. The Airport base station will now take about a minute to reboot. Here's what happens when you perform these steps... The utility changes your existing Airport network to 2.5 Ghz, and then creates a new 5 Ghz network with the new name. (It will apply the same password to both.) You will use the 5 Ghz network, the new name, for any new wireless computers using Leopard or newer OS. You will use the 2.5 Ghz network (bearing the original network name) for the older laptops running Tiger. This fix worked immediately, no problems. The issue is that Tiger does not perform well with 5 Ghz networks, and this causes the kernel panics. I now have two old G4 laptops running Tiger, both using my new Airport base station with the 2.5 Ghz network and running perfectly. At the same time, my new machine is using the 5 Ghz network at the same time. It seems quite stable. Good luck, and I hope this info is useful.

Firefox is trying to update my 8.0 version to 9.0.1. I'm not ready to do so because the Norton Toolbar is not yet compatable with the new Firefox release. How do I get firefox to stop trying to update every time I open the application?

This reads backwards, It is the other way as "Norton update is compatible with Firefox 9".

I just got my refurb iPad in the mail. I am trying to set it up, but im getting this message "iTunes could not back up the ipad because the backup was corrupt or not compatable with the ipad. Delete the backup for this ipad. then try again." How?

I just got my refurb iPad in the mail. I am trying to set it up, but i am getting this error message " iTunes could not back up the ipad because the backup was corrupt or not compatable with the ipad. Delete the backup for this ipad. Then try agian." How do I do that?

It sounds like the iPad wasn't erased to me. If the iPad is totally cleared of content, there should be nothing on it and no backup to create.
Without connecting the iPad to your computer - Launch iTunes on you computer and go to Edit>Prefences>Devices. Do you see an iPad backup in there? If you do see it, delete it.

I'm trying to find an external drive for the MacPro that will allow me to password protect the external drive in case it is taken. Any suggestions on a very reliable on that is 2TB or a third party software that is compatable with the need I describe?

How much of a hurry are you in, and are you considering upgrading to Lion?
File Vault on Snow Leopard only encrypts home folders you select, and doesn't work well with Time Machine.
But Lion will have "full disk encryption" of local or external disks. See File Vault 2 here: http://www.apple.com/macosx/whats-new/features.html

Is the Ultimate Ears Super fi 4vi headset compatable with the iPhone 3G?

I am thinking of getting the Ultimate Ears Super fi 4vi headset. Will it be compatable with the iPhone 3G?
http://www.ultimateears.com/ultimateears/products/superfi/superfi4videscription.php
If it is compatable, is it any good?

Ah thank you. I actually just went to the Apple Store in Rosevelt Field (I'm a fellow NY resident as well ) They unfortunately never heard of Ultimate Ears and only had the V-moda vibes. I decided to not purchase the V-moda vibes today because i dont think it would be wise just because they were in the store and the Ultimate Ears were not.
I'm on LI.. So i think a trip to the apple store on 5th is probably not worth the trip. I'll probably just order them from Apple.
I'm still leaning towards Ultimate Ears, are they really that devoid of bass? All of the reviews on the apple store seem to say theres no bass at all.
How do they compare to say the default iphone buds?
I'd rather not have bass that is destroying the other frequencies. I like bass, but i like mids and highs as well. I know a lot of earphone companies just tend to focus on bass, cause its fashionable.
But there is definitely more to music than just bass. Thats not to say i dont like nice tight bass.

It's a good camera which I think has been overlooked in this area?
Any advice you good people?

Hello,
I don't know when but you can send a message to Apple so they can add that in a next update (not 100% sure but you can try).
Go here : http://www.apple.com/feedback/aperture.html and in the Feedback Type select : Harware compatibility.

Is the old HP-IB on a ribbon cable compatable with the now standard GPIB?

I have found a HP61001A and associated 61016, 61014 etc test equipment. It uses a ribbon cable to interface. Would anyone know if this is compatable with the now standard GPIB? Could it be used with some form of "connection converter"? Many thanks for any help.

Dave,
I recommend that you call HP to determine if the instrument is 488.1 compliant. If it is, then you can use GPIB boards (even 488.2 boards), but you must use 488.1 commands (such as ibwrt and ibrd). If the instrument is not 488.1 compliant, then you cannot use it with GPIB.
I hope this helps.

What cameras are compatable with the SD card accessory?

Is there a list of cameras that are compatable with the SD card attachment?

The camera Connection kit has two parts, one is the SD card reader. The SD Card Reader supports SD standards up to SDHC, miniSD and microSD with adapters, and MMC. SDXC is not supported.
The second part is an attachable USB port. Most digital cameras with a USB cable should work with the iPad.

Are you going to reestablish compatibility with the Norton tool bar?

Are you going to reestablish compatibility with the Norton tool bar?
Version 4 seems to have lost this compatibility, which version 3 had.

It is down to Norton to make their add-ons compatible and they are working on it. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US
I do not know about the time scale for updates for other Norton products. Pending the update by Symantec, if you want to use the Norton add-ons you will need to downgrade to Firefox 3.6.
To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

However, if your Mac has only Firewire 800 ports, you need an adapter such as one of the following to connect your FW400 external iSight:
• This Firewire 400-800 cable can work: http://store.apple.com/us/product/H7041ZM/A (I use this one.)
• Some report that this low-priced alternative cable works:
http://www.newegg.com/Product/Product.aspx?Item=N82E16812189097
• To use your iSight's FW400 6pin-6pin cable, you can use a 6pin-9pin adapter like one of these:

Is there a way to find out if current Add-ons are compatable with the latest upgrade ver. of Firefox before running the update?

I want to know if my current Add-ons and themes are compatable with the latest upgrade version of Firefox before running the update.

Hello azdec.
You can check the add-on's page at [http://addons.mozilla.org addons.mozilla.org] if it's just one or two. I believe there is one extensions in the add-ons gallery that lets you see whether your add-ons are compatible with newer versions of Firefox. But you'll have to search for them, since I don't know how it's called.
I will remind you that if you want an add-on to be compatible with a newer version of Firefox, you need to contact its author.
Also, the version of Firefox you are using at the moment has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems. I urge you to update to the latest version of Firefox, for maximum stability, performance, security and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com].

HT4623 how do I either: 1) turn off comptability feature, or 2) up grade the .exe to be compatable with the iphone ios 6.0.1 software. The computer will not recognize the phone.

How do I either: 1) turn off comptability feature, or 2) up grade the .exe to be compatable with the iphone ios 6.0.1 software. The computer will not recognize the phone. I reinstalled itunes, but it still does not work.

What are you talking about? There is no "compatibility feature" on the iPhone, and .exe files won't run on the phone.
Please slow down and explain exactly what you're trying to do and what happens when you try.

Upgrading raid firmware messes with drive data?

I need to upgrade both 1.5.0 controllers on one of my x raid so that later I can use then on a second x raid with 750gb drives. the second x raid is having lots of problems losing connection to a xserver and I need to pinpoint to see if it is a controller problem.
the question is. upgrading the 1.5.0 controllers to 1.5.1 messes with the data and settings on a simple raid5 on both sides of the raid storage? I don't have the time and mainly space to backup the data.
thanks.
Nuno

No upgrading the controller firmware doesn't affect the drives/arrays or data.
That's not to say you shouldn't have a viable backup of your data, but it's not a prerequesite for updating the firmware. :)
