 | SCSI device will not mount
by Don Jaksa on Jun 21, 2003 at 4:00:17 pm |
I am trying to mount a Medéa raid SCSI device and have been having no luck.
The device is showing up in the System profiler as an IOSCSIParallelDevice but is not recognized at all by Disk Utility and any third party disk utilities.
I believe that it is an issue with the SCSI host driver not being used for the device. I have installed the driver, but don't know where to look to find it or how to force it to be used for this device.
Any help is appreciated here, I am totally at a loss.

hello...
sorry - i have absolutely zero experience with scsi on os x... :-(
the only thing i can offer is our medea forum and contacting them directly with your issue...pretty useless, but it's all i got...

Without more details it's hard to troubleshoot. Here's some possibilities based on what you told us:
1.) What did you use to format the Medea? If you didn't use Apple's OS X Disk Utility or an approved OS X RAID utility, it won't work. Typically OS 9 formatted RAID's don't mount under OS X.
2.) The same goes for the SCSI card. Is it up to date and approved for your computer and OS X? Check with the manufacturer to see if it will work and if they have any updates for it.
3.) Lastly, try different cables. Check your current ones for bent pins. If you have anything else on the SCSI chain remove it for now. Check you termination. Remove the internal card and try it in another slot.
Good Luck,
Tony!

The Medea has not been formatted. I can not access it in order to format it. Disk Utility does not recognise the drive. However, Sytem profiler sees the drive attached and lists it as an IOSCSIParallelDevice.
The card is okay with OSX and is recommended by Medea in an OSX application. The driver have been loaded but the card will not accept a flash to update the firmware. Not sure if current firmware supports medea. However, the card DOES recognise and mount an internal SCSI drive with no problems.
Cabling is what came with the Medea drive and is recommended. If the device is showing up in System Profiler, it appears that it is communicating fine. I am more concerned that it is coming up as an IOSCSIParallelDevice and I believe that it is using the wrong drivers for the medea or ATTO. However, I do not know where to look in order to trash the drivers.

Did you check the pins on your SCSI cables to make sure none are bent. They are very easy to bend and could cause the drive to be seen, but not recognized correctly. Remove and replace the card as I suggested. Try a different SCSI card, cables, and the Medea on a different computer if you have access to any of these. Check to make sure the termination is on and remove any other SCSI devices attached to that card (or the Medea) for now. If is still does not work, call Medea on Monday, they are very helpful.
Tony!

Cable checks out Okay, as I said, it also shows up in System profiler, so I know that it is communicating.
The Medéa also works fine when I connect it to my Adaptec 39160 card. But this card is not supported for RT uncompressed with my Aurora Igniter card. Medéa recommends using an ATTO UL3D for best performance under OSX.
I have moved the card to different slots and also removed all other cards to eliminate a hardware conflict. Ireally don't think that it is a hardware issue. It is something regarding the drivers or firmware.
I was hoping that someone on the forum could point me in the right direction to find the drivers so that I could trash the files and start from scratch.

Thanks fot the help Tony, but no such luck. I have calls in to both Medéa and ATTO tech support. This is a wierd one.

I've got a number of Medea drives working with OS X. For some reason the system didn't like ID #3 and wouldn't recognize any of the 3 drives with one using that ID#. Changed Id #3 to 4 and everything worked. Just a shot in the dark. Good Luck.

Did they appear in system profiler for you??
I have called tech support from ATTO and Medéa and have narrowed the problem down to a firmware issue with the ATTO card. However, since it is an Apple OEM card, the ATTO updater will not work. So I don't know how to get the firmware updated. Any ideas (can't find anything on the apple site).

Don Jaksa,
I saw this(old) post on Creative Cow and wondered if you had solved the problem. I have the same: in OSX the ATTO UL3D shows up in the system profile but the drives do not mount. In OS9 they both mount. I guessed it was either drivers or some flash problem, but like you could not find a solution. Any luck?

I discovered that the ATTO UL3D card that I was using was an Apple OEM version of the card. Meaning that the card was designed for sale and installation of Apple machines directly from the factory. This version of card is slightly different from the ATTO UL3D retail card, using different IC's and different firmware.
The catch is in the firmware, the Apple OEM card WILL NOT accept a firmware flash (and is designed to not be upgraded) so you are stuck with the firmware that the card shipped with.
In my case, the conflict was that my Medea drive needed a newer version of firmware to work with the card, so I was screwed.
I ended up calling Medea and we configured the caching scheme of my Medea to work with my Adaptec 39160 SCSI card and now I am editing real time uncompressed using the Medea and Adaptec card.
I sold the useless (in my case) UL3D card on E-bay for the same price that I paid for it because the dealer that sold it to me refused to refund my purchase price. I no longer use that dealer.
