I have done the following to try to resolve this problem: 1. remade the devices in /dev (no change) 2. checked termination of SCSI chain etc. (no problems I can see) 3. connected the disks to a 2940 controller on another machine (dodo) - they are in an external enclosure, with the terminator in the same position etc. In this case I was able to label the disks without any problem, but when I reconnected them to the first machine, the problem appeared again. The differences between the 2 machines are: dodo: 2940 with normally 1 disk on internal bus (this one works OK with the 2 additional disks from anfi) anfi: 2x2940 with 8 disks and a tape drive. controller 1: 1x2GB disk (sd0) 1x4GB disk (sd1) 2x9GB disk (sd2,sd3 => ccd0) controller 0: 2x4GB disk (sd4,sd5 => ccd1) - this is a very busy squid cache 1xHP DAT drive 2x4GB disk (sd6,sd7) - these are the problem disks) Could the problem be related to the problems with the ahc driver that were recently fixed in the 2.1.7.1 point release? If so, is there any way I could migrate those changes into my 2.1.6 system in the interim until I have an opportunity to upgarde the machine. I need to get these disks working on the machine so I can update my ftp site (including the FreeBSD mirrors). Any other suggestions ??
