I'm much the same as jschiwal, as it's been a while since I've done this but from what I remember, SCSI ID (or LUN) 0,0 is the ID number of the controller card & the drives that you connect to it are sequenced from there.
Like as follows :
LUN 0,0 --> controller card
LUN 0,1 --> 1st drive (the one plugged into the cable closest to the controller card)
LUN 0,2 --> 2nd drive (the next on the cable)
LUN 0,3 --> 3rd drive .......
You get the picture!
The order above is not absolutely critical as long as the first drive is not 0,0 & every consecutive drive has a
HIGHER LUN than the last! A
LSO, I FORGET IF THE 1st DRIVE PLUGS INTO THE CABLE CLOSEST TO THE CONTROLLER CARD OR IF IT SHOULD BE THE LAST ONE!!! SIMPLY TRY THEM BOTH!
So for your drives to work you will have to figure out how to set the jumpers (terminations) for each drive to define it's LUN (SCSI ID) This info should be either on the drives themselves or at the manufactures website.
Other things to check for are that the scsi modules are loaded, the generic ones that are necessary are :
sg
scsi_mod
& the correct driver module for the controller card will also need to be loaded, this will differ from card to card. Without the two generic modules, sg & scsi_mod, you won't get anywhere!
Then check dmesg for scsi entries with :
Are you running an older 2.4 kernel or a newer 2.6 kernel? as they have slightly different ways of configuring scsi.
Which distro are you running??
Post the results of the above questions even if you figure it out for yourself. Once these questions have answers we can dig a little deeper & hopefully get things working as they should!
