camcontrol cdb to disconnect drive
Hey, all. I want to replace a 9 GB SCSI drive with an 18 GB SCSI drive. All the hardware supports hot-swapping. Just for kicks, I thought I'd try to turn the drive off via SCSI commands and replace it without rebooting. The camcontrol utility doesn't have a disconnect command or a stop unit command (that I can find), so I was going to try to use 'camcontrol cdb' to send a stop unit command to the drive. Has anyone done anything similar? Can someone help me locate the necessary parameters to use for this command? All I can seem to find with Google is a quick reference for SCSI commands. It tells me the command to use is 1B, but I don't know what other details are needed to fill out the CDB command. I need to fill 6, 10, 12, or 16 bytes, and I only have the first.

There's also a 'start' command. -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
