The system has three SCSI adaptors: two Adaptec 2940UW cards that run traditional disks, and an Adaptec 2944W that I added today to run the Symmetrix array. The array has a differential fast-wide SCSI 2 interface. The array is configured such that I should see four 8.5Gb volumes, at SCSI ID 0, LUNs 0-3. However, I only see ID 0 LUN 0. This one volume appears OK, except that FreeBSD doesn't like the geometry (see below). Is there anything special I have to do in order to see the other LUNs? Also, the logical geometry reported by the Symmetrix for each drive is 18,410 cylinders, 15 heads, 64 512-byte blocks. FreeBSD doesn't seem to like this idea. How can I make FreeBSD happy with the geometry? Finally, how can I configure ccd to use the four disks with plain concatenation, not striped? The man pages aren't clear on how to do this. Any help would be greatly appreciated. -- Robert Levandowski Internet Systems Analyst ACC iNet / ACC Long Distance Corp. robl@phoebe.accinet.net
