We have two StorageTek 2540 units here, both with 1 controller at FW version 07.35.44.10 (supplied with CAM 6.4.1). I tried various things with two versions of CAM, namely 6.9.0 and 6.6.0, both giving me the same errors:
- If I put both controllers in one enclosure and try to upgrade them, I get an error that 'staged download is not supported', thus failing the FW upgrade
- If I put the controllers in separate enclosures and try to upgrade, I get the error that they are degraded and cannot be updated: "Could not connect to array. One of the controllers is not reachable. Check network and password."
- If I try to set the redundancy level to simplex using the 'service' utility, I get an error 'Authentication failed - couldn't read password'
- Many options in the web interface give errors, I can't even rename the array, reset a battery age, create a volume, etc.
Is there some way to completely reset the configuration or force the firmware to be upgraded, even though the arrays are degraded? I can't do anything with them now... The IP addresses of the arrays are configured over DHCP, this should not be a problem, right? They get the same address every time they request one, though.

It's not clear what you plan give at finish.
One box with two controllers or two box with single ?
It's look like configured password on controller. You can clear ( reset to default) via serial connection.
In the end we would like to have two enclosures with one controller each. We thought it would be easier to flash them together, since they had the same firmware anyway. I have reset the passwords using the serial console before, but I did so again just now, to no avail (same errors). Too bad there is no hardware reset button or anything...
I was able to resolve this issue by pulling out the controllers out and put them in another, working 2540 array, one at a time. This way, they both copy the data from the active controller, causing them to both have the same firmware and nvsram. After that I set the redundancy to simplex and placed them into their own enclosures with wiped disks (so they don't copy an old nvsram backup from disk).
