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? I'm trying to write an udev rule, but it seems that the system ignores the "vendor" model/name of the controller... For example: I want to disable /dev/sdb; so I gather some information with udevinfo -a -p /sys/block/sdb and I try to use them to write /etc/udev/rules.d/10-custom.rules ID=="?:0:1:0", BUS=="scsi", DRIVER=="sd", SYSFS{model}=="DDYS-T36950N ", SYSFS{vendor}=="IBM ", OPTIONS="ignore_device", OPTIONS+="last_rule" I put the "?" on the ID field because I know that the order of the controller can change (a kernel update could trigger the switch); also I tried with and without the spaces at the end of vendor and model: no change Where am I wrong? It is a different way of doing this? TIA Ciao Lorenzo
