Hi all, do you know if there is a way at boot time do disable specific LUN's on a SCSI bus of a particular controller?
What do you need to do this for?
How about just echoing the command to /proc/scsi/scsi
echo "scsi remove-single-device X X X X" >/proc/scsi/scsi
get the values for the various X's from /proc/scsi/scsi e.g. Host: scsi0 Channel: 01 Id: 00 Lun: 00 Vendor: MegaRAID Model: LD 0 RAID1 69G Rev: 521S Type: Direct-Access ANSI SCSI revision: 02
would be 0 1 0 0

This is what I'm doing right now; but I was searching for a way of doing it earlier on startup. I'm playing with a non partitionable DS4300 FC, and I would like to avoid LUN contention.

--- scsi_dev_flags SCSI black/white list. scsi_dev_flags=vendor:model:flags This option lets the user add entries to the SCSI black/white list for a specific vendor and model of device.
Dug it up from my notes. This goes on the kernel boot line.
