Appears that way... but when the dmesg stuff flies by I am pretty sure that the Asus card is detected as sym0. > Go back to the raid controler and plan ahead before removing the Mylex > (DAC 960?) RAID card. The original Mylex card is not available. The resources are not available to have a replica if every peice of hardware contained here. Therefore, a new card, a similar one, or the orignal one is not an option. > OR, Sacrifice your second drive and rebuild with it.

Start a regular install and make sure I somehow distinguish the second drive and setup a new install on it. There must be a way to tell FreeBSD the old controller crapped and I am replacing it with a new. > Proper, prior, planning, prevents, piss, poor, performance.

In a real world mission critical envrionment I would insist on proper, prior, planning, etc. Thank you for your time, D To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
