My configuration is: 8 4-gb Seagate drives on one Adaptec 2944UW controller ( two identical setups. 64 GB total, two controllers, 16 disks) I plan to use ccd to create two 32 GB logical volumes for the system. My question/comments: Am I missing something in that it looks like I have to configure the kernel to support two controllers? The controllers are probed and detected at bootup, but where do they show in the /dev directory. What are the device names that reflect the controller number in the disk device names ( /dev/cont??sd0s7). The handbook is very lacking in the part of adding disk drives. Do I need to get a BSD manaual to cover adding disks. I am fairly competent in various UNIXs (Intergraph, SGI, Sun) but I am a stranger to FreeBSD. .I have added ahc1 to my kernel config file. I have defined scbus0 as ahc0 and scbus1 as ahc1. I have locked-down the device numbers to the scsi ID (this is a really primitive thing to have to do). I have rebuilt the kernel and am proceeding. Anyone have any good tips on adding drive arrays like these? They would be greatly appreciated Chris Sagar Csagar@iterated.com
