I eventually figured out that I was having pretty much the exact same problem as the guy in this thread: http://www.spinics.net/lists/linux-ide/msg38500.html The unlock command[1] there worked once the disks settled... and my claim of them working fine direct attached was based on an identical disk that hadn't been molested by the 3ware controller. Having the kernel detect a 'drive is locked' condition and give an error about that (as suggested in the other thread) would have saved me a few hours of troubleshooting. It looks like some work was done on a patch to implement that functionality[2] but I'm not sure what became of it - this particular box has 2.6.38 on it which hasn't implemented that. If you would still like the full dmesg output let me know and I'll dig up my logs and attach them. 1. hdparm --user-master u --security-disable "3wareUserPassword " /dev/sdX 2. http://www.spinics.net/lists/linux-ide/msg38566.html -- Ryan Castellucci http://ryanc.org/ -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
