Hi, Not sure if this is the right list for my question but I couldn't find a more suitable place to ask it. I'm trying to set the locator light of a disk in a SAS enclosure using sg_ses but I'm not getting anywhere. I'm dumping the enclosure status diagnostic page using 'sg_ses --page=2 --raw /dev/sgXX > page' and then set the SELECT and RQST IDENT bits of the array device element in question and write it back doing 'sg_ses --control --page=2 --data=- /dev/sgXX < tmp'. The command completes without error but unfortunately, nothing happens. When I read the page back, the IDENT bit is still cleared and the light on the enclosure remains turned off. Am I doing something wrong or am I missing something? Can't I use sg_ses to achieve this? Thanks in advance for any help ...juerg - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
