need help replacing raid controller
i have a poweredge 2600 that has a failing raid controller. i bought an adaptec to replace this, but i cant get the card to see any of the drives. the card is a 2120s and support 320MB and I am using a 320 cable with terminator.
I think my issue might have something to do with the LSI Logic??? I have tried a different raid controller (also adaptec) and a different cableand i get the same. If i put the failing dell perc controller in, it sees all the drives fine.
What am i doing wrong? I am sure the cable and card is good. Is there something I need to disable in the LSI Logic or remove from the server?
Thanks

The drives should be visible, but your raid configuration most likely will not be picked up.
You may need to initialize the disks (wiping all data) before the Adaptec controller can see the disks and create new raid containers. After that is done you can restore your data from tape.
The alternative is to buy a PERC3 or PERC4 (if you had a PERC4, you shouldn't get a PERC3 as a lower model card may not recognize the same raid containers), and put that in so you can use your existing configuration and data.

as i cant see them in the adatptec card, should i use the failing perc card the initialize?
the adaptec card locks up when i hook up the drives right now. do i need to make any changes in the LSI Logic? Also, the Adaptec card only has 1 port on it, but my cable has 7. I was just going to hook up the 2 drives bays to this one port. Could this be a problem?

Personally, my first choice would be to replace the failing card with a similar card.
But if you want to stick with the Adaptec card, the raid config on the drives shouldn't prevent the Adaptec card from seeing the individual drives as such. Therefor I'd look into other possible causes.
Are you using a hotswap backplane and the original cables (to connect the PERC to the backplane)? You mention having a cable with 7 connectors; this is usually used to connect multiple harddrives to that cable (this would mean without a backplane), and you'd need an active terminator on the last connector on the cable to terminate the scsi signal. If you're using this cable to connect to the backplane, make sure there's no terminator on it by accident as the backplane terminates the scsi signal and having 2 terminators could (will) cause weird issues.
