IDE to SCSI converter

Tuan Nguyen — Mon, 27 Dec 2004 11:14:38 GMT

Hi,
I tried to add more space for the K210 HP-UX server. I just bought an IDE to SCSI converter model ADAEC7726H. I plugged it to a 200GB IDE Western Digital Caviar SE hard-drive. I installed the hard-drive (with the converter) but the K210 server did not recognize the new drive and other drives on the same bus. Any idea ?

Thank you very much.

Yes,

Because the converter and or the drive are not supported by hp-ux.

I do not believe your current attempts are going to succeed.

Better to stick the 200 MB drive in a pic, install Linux and set up an nfs or samba share.

Steve,

Thank you for your quick response. This converter claims to work for Solaris. So I thought it might as well work for HP-UX. Well, I tried.

Can it be that the adapter had termination enabled or parity disabled - I'm quite sure (and hope for) You just mixed up something like that.
Or maybe You hit the hostadapters scsi address.

I don't (yet) possess one of these, but I hooked up about anything that has scsi to my old hp755 without any problems.

Good luck,

Florian,

Thanks for your response. I am not sure how I am going to enable or disable these features. It seems to me that this converter is quite simple to install. It has a 68-pin female SCSI connector, a 40-pin female IDE connector, and the jumper setting. That's all.

Tuan, IDE and SCSI are two fundamentally different ways of communicating between hosts and disks. There is no possible way that a simple connector/adapter that converted 40 pin IDE could connect to 68 pin SCSI. Very simply, there would have to be a LOT of logic in the circuitry to change the IDE signals to SCSI or vice versa. The only reason to use an adapter like this is to save money. You'll spend as much or more money converting between these signalling standards than you would just buying the appropriate drive to begin with. If you need an IDE drive, buy one. If you need SCSI, buy that instead.
I would be suprised if what you'e already done hasn't already broken something. You may haver already fried something. You should open the case and very, very carefully inspect the components for melted solder joings or worse.

Obviously, the Addonics converter is more than just a simple IDE to SCSI adaptor. It has an integrated high-speed logic controller, supports a multitude of OS choices, supports up to LVD160 controllers and has upgradeable firmware.

Suggestions.... check the SCSI id, make sure it is not conflicting with anything else.

Else, the specs did not include HP-UX as being compatible, maybe it just won't work with it.

Stupid questions...
Did you connect power to it? It has a 4 pin power connector.
Did you set the ID properly? It has a standard binary ID jumper setting system.

Steven,

I plugged the small 4-pin power supply to the controller and the regular power supply to the hard drive. I currently have 3 hard drives with scsi id 6, 5, and 4. The additional drive (with the converter) is set to 14.

ID:14 is an address in the 'wide' range. If your HP-UX server's adapter only works with narrow devices (which I don't know. but like to mention anyway), this will not work.

Do you have any devices connected to the FW SCSI connector on the core I/O in the back of the server?

Tuan Nguyen — Tue, 28 Dec 2004 16:37:12 GMT

Uwe,

I changed the scsi id of this drive from 14 to 3, but the server still does not see it.

Joshua,

I took this drive and hooked it up with the external drive case and attached it at the back of the server. The server still does not see it.

Tuan,

One thing to be aware of is that the SCSI drives in the K series are High Voltage Differential drives. These are almost impossible to find anymore. I'm guessing that trying an adapter with the HVD would fry the adapter.

Just my 2cts worth,
Mark

Re: IDE to SCSI converter

Joshua Scott — Wed, 29 Dec 2004 12:15:13 GMT

Mark has hit it on the head. the adapter's specs say Ultra160 SCSI which is not compatible with HVD or FWD SCSI.

Thanks guys. Basically, I am out of luck on this one.

THanks for all your information.
