The card can tell it's there, but the OS doesn't see it. Only a reboot will correct the OS view. The same also applies when building a new RAID partition using the Adaptec-supplied RAID configuration program. A RAID partition looks to the OS like a different drive type than the drives it replaced. Rescanning the asr SCSI bus won't find the new "ADAPTEC RAID-1" pseudo-drive, but will manage to see the loss of the old drive, thus making the disk "go away" to the system, again until reboot. >How-To-Repeat: Add a drive to a SCSI bus controlled by the asr driver, and run "camcontrol rescan" and "camcontrol devlist". You won't see the new drive. If you have the Adaptec RAID configuration program, you will be able to see the drive with "raidutil -L all". >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
