I recently picked up 3 storagetek 2530's (with 12x 72gb's each), 12 300gb SAS, 12 400gb SAS, 12 1TB (SATA), plus controllers, and a serial cable. The units are attached to a server and I can see the array drives. The units are currently configured with some old 72gb drives.
The problem is I don't know the management IP nor password, and I've followed the docs on how to try to reset the ip using the serial cable. I was able to connect once momentarily a few weeks back but have yet to be able to reconnect (afer multiple power up attempts). I'm not ruling out a bad serial cable, but I'm skeptical about buy a new one with how some people are metioned there are ones with incorrect pinouts, so I don't even know which one I would replace it with (or what the best place to get it at would be).
What I need to know is:
1) Is there a way to factory reset these guys?
I don't care about what's on them now, but I don't want to spend hours clearing configurations.Please follow the instructions in the document http://docs.oracle.com/cd/E19508-01/820-0015-14/820-0015-14.pdf chapter "To Connect a Terminal to the Serial Port" page 91.
2) How exactly do you connect with the serial cable?
I've tried using putty, but the questions is what are the proper key sequence to hit when I need to break AND when should I be doing this? Do I have to wait for the array to be complete up? Is it like a PC where you need to do it before a certain event? I'm just clear if I'm doing it right at all.Please follow the instructions in the document http://docs.oracle.com/cd/E19508-01/820-0015-14/820-0015-14.pdf chapter "To Establish a Connection With the Serial Port" page 93.
If I recall correctly, when I got it to work weeks again I was playing with the flow control and "None" didn't work and I had to change it, even though the document said None.You cannot daisy chain 2530 controller trays. However you can attach expansion trays to a 2530 controller tray. The expansion trays do not contain controllers, they contain IO Module (IOM).
After I resolve the first two issues, I'd also like to know if I can daisy chain these directly or is there a different module that you need for the 2nd and 3rd arrays? I'd like two of these arrays on one computer, and the 3rd on another. This is probably less imporant but I figured I'd ask.
Anyway, any help would be greatly appreciated

Not sure how to reply to a specific message here.
I have review that document as well as a few others. I'll try again after getting a different cable.
The only question I have, that I can't find an answer to is when am I able to send the control break sequence?
Can I just start the unit up for 5 minute, attach the cable, and try, or do I need to do it after a powerdown/power up cycle? Should I be using the PS/2 connection on the left or right controller, etc... I just don't know enough about this and I'm trying to learn everything I can before I really start using it. Also, while I'm troubleshooting this, is it advisable to leave both controller cards in or should I remove one to simplify the troubleshooting.There are situations in advanced troubleshooting when we pull one controller. However in your situation you should leave both controllers inserted.
As for the daisy chain, it's not a problem. I have multiple pass through cards and I will just add a second card to that box. I just did't know if you could daisy chain them that way.
